Thanks to the generosity of the Stellar Product Testing Panel, I received the Cybex Eternis S All-In-One Car Seat in exchange for a review. My 7-month-old daughter is getting harder to carry in her infant seat, so this convertible car seat arrived at just the right time. Upon removing it from the box, I took note of the high quality of the materials used to construct the seat. The fabric is soft, and the seat looks very plush and comfy. I loved the separately reclining headrest. My daughter occasionally naps in the car, and the headrest lets her relax more comfortably. Although the car seat is large (and definitely not something I would want to switch between vehicles on a regular basis), it is not as bulky as some other car seats on the market. Regarding safety features, I especially like the LSP System. It is easy to activate with the quick press of a button, and it gives me peace of mind to have extra protection for my child in case of a side-impact collision. In terms of convenience, I liked the magnetic holders for keeping the straps on the side of the car seat when removing my child from the car seat. My other children's car seats have different ways of keeping the straps out of the way, which do not work as well as the magnets. The only thing I do not like about this seat is how difficult it is to use the chest clip. On the flip side, hopefully that means my daughter will not be able to unclip herself easily as she gets older. I was very surprised to see that this seat can be used for 10 years and that it can be used rear facing and forward facing and then convert to a booster. I'm looking forward to watching it grow with my child!

My husband and I loved having the opportunity to try the CYBEX Eternis S All-In-One Car Seat for our son! Aesthetically, the car seat is a great color with excellent fabric, and it looks really nice in both our minivan and our SUV. We loved the subtle cushioning and comfort that this seat offers our son while still providing safety and sturdiness. We were intrigued with the Linear Side-Impact Protection (L.S.P.) and loved to be able to use it while our son was in his seat. Any extra protection of our baby boy is excellent and much appreciated, and we feel that it shows the extra thought that went into the design. The 3-Position Reclining Headrest was a great feature to make our son as comfortable as possible in his seat, especially when he falls asleep while we drive. It was easy to adjust, and we saw a difference when we adapted the seat to his comfort level. We look forward to using this seat for him (potentially over the next ten years), and were excited to see that it would last him a long time! Our two daughters (our son's older sisters) wanted to try out their brother's new seat, too, and it was effortless to adjust to their heights and comfort levels. It is obvious that this is a well-designed, safe, and reliable car seat, and I am happy that our son has it. I would highly recommend it! Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat.

My initial thought after using the CYBEX Eternis S All-In-One Car Seat is that they thought of everything! I received this car seat through the Stellar Product Testing Panel, and as someone who has used an all-in-one car seat for nearly two years I thought, what could be so different about this one? Guys...it's like they kept everything I loved about my all-in-one car seat and tweaked those little things that drove me nuts every time I buckled in my three-year-old! For example, a slightly larger cupholder than can actually hold a toddler-sized water bottle so I don't have to reach back and yank it out for my son every time he wants a drink. And magnetic belt holders to hold the buckles out of the way. And the straps glide SO easily as you tighten and loosen them. But the pièce de résistance: the reclining headrest. Game. Changer. Every mom hates when their kid's head rolls forward when they fall asleep. It restricts airflow and ultimately isn't comfortable, so you child doesn't sleep as soundly (or as long...). I was skeptical that the reclining headrest would actually keep my son's head from falling forward but it. works. And my son even commented how "cozy" his new seat was, unprompted. This is especially important to me now that we're driving to and from my parents' house 375 miles away and 5+ hours up north to our cabin all summer. Of course I love the added safety features and the fact that this seat will fit him until he's 120 lbs, but the fact that they paid attention to the little details and got those right really made all the difference for me. The CYBEX Eternis has permanently replaced our former all-in-one car seat in my vehicle! For reference - I drive a 2018 GMC Acadia and my son is three years old (30 lbs, 38" tall).

This car seat caught our attention with the beautiful design and fabric, but when we learned that it grows with our child, we were so excited to receive it and get it installed. Being able to use one car seat for 10 years is incredible! It was very easy to install with the latch system and came with clear and simple directions. As a mom of 5, I've tried multiple brands/styles, and I'd have to say that this car seat really impressed me with the safety features. We are in the car often, and the 3-position reclining headrest has been so nice for car naps and being comfortable while preventing my child's head from falling forward while asleep. The quality is very impressive and the steel reinforced frame provide lots of peace of mind while driving. Safety is always my number one priority, with comfort and ease of use tied for second. Both my newborn and my 1 year old have been able to use this car seat, and the ease of adjustment between positions for proper fit plus the quick install reference guide and level indicator on the side car seat has been so convenient for our family that is always on the go! Can't say enough about this car seat, and I'm confident that the quality will last over the next 10 years. I received this amazing convertible car seat from the Stellar Product Testing Panel.

Thanks to the Stellar Product Testing Panel, I was able to try this AMAZING car seat! I absolutely love how this car seat goes from infant to child; I have three children (8 months, 4 years, and 6 years), and ALL of them can use this car seat, which makes it unbelievably awesome to have it in my husband's car for quick and easy school pick-ups without needing to swap seats. If you have limited storage space like I do, you will appreciate this car seat's extended life and versatility. Safety features are our number 1 priority, and this car seat ticked all the boxes. It's sturdy and doesn't shift. And, I love how the booster still has a full back (not just the seat cushion) with the normal seatbelt fitting across and under a notch - it provides better protection than only a booster seat would. The car seat also has wing-like structures on the sides that can extend to create a bumper in case the seat shifts in an accident! The three-position headrest made this comfortable for all three of my kids regardless of their differing heights and long torsos, too. If you need a car seat that'll last a long time - this is it!

I was excited to try a different type of car seat when I received this product to test as part of the Stellar Product Testing Panel. There were quite a few features that made me intrigued if it would be a good long term solution for our family! After trying it for a few weeks, my conclusion is that it is a great car seat and I would recommend it but would make sure people knew a few things about it first. The positives were: - the whole LATCH system! There's a place to store it when it's not needed -- there is a place to rest your thumb to press it into the seat -- it has a pull tab so rather than needing to get my fingers into the seat and push hard on a button to disengage the latch, the red pull tab was easily visible above the seat crease and with a quick pull I could disengage the latch when needing to move the seat -- and, my favorite, you can tighten and loosen ON BOTH SIDES so it doesn't matter what side of the car the seat is on! - the 3-position reclining headrest! I tried this seat with my 12 month old (rear facing) and my 3.5 year old (forward facing) - other car seats I've tried have a straight back so when they fall asleep their head ends up falling forward. In this seat, I could recline the head portion so their head tended to fall to the side against the headrest - yay! - the hardware (buckle, LATCH, shoulder straps) was all installed in a way that made it easier for things not to get tangled when moving straps around. - the fabric has so far spot cleaned incredibly well! Gunk from food pouches? Rubbed with damp washcloth and it was like new! - the safety features - I had not seen a pop out side on a car seat before and it made me feel like they had more protection from potential side impact. - the longevity - being able to use this car seat from birth to 120lb can be a huge plus for families not wanting to buy a seat for different stages! - easy to change positions back-and-forth at the bottom of the seat and up-and-down for the headrest/straps. - I like that the bottom of the seat flips open without having to remove the cover - makes it easy to change the strap positions or guide a seatbelts through While using it, the things I wish were improved were: - the weight of the seat - this is not a seat we could easily move between cars. Weight is somewhat subjective based on your strength, but as someone who lifts weights regularly, I found it heavy. My mom is a very active person and said it's the heaviest seat she's had to move. Even if you don't plan on moving it between cars that often, it makes taking it out to clean a hassle. - ease of removing and putting on the seat cover - I felt like I was going to stretch the fabric to the point of tearing when trying to take it off to clean. It was a bit cumbersome to get the cover back on, too - the edge needs to fit into a crease around the outside and my fingers took a bit of a beating getting it back in. BUT like I said above, the fabric spot cleans super well so you might not need to wash the whole thing very often. - The cupholder sticks far off to the side which makes it hard for the kids to grab things in it and wouldn't allow for positioning in the middle seat if I needed to get three seats across. Other things I noticed: - The material is very soft which is great for the kids to be comfortable sitting in but I wonder if in a few months it is going to show pulls in the fabric like another seat I used that had a similar feel. Not happening yet (which is great) but something I'll be keeping an eye on. - the tightening strap is has a plastic piece around it that, when I had the seat rear facing, would pop up when I was tightening because of the angle I needed to pull the strap at. When I looked closer, it looks like it's made to come off of tabs but there isn't a way to press the tabs in - it just comes comes off and tilts when it's pulled on hard enough at a high angle. Hope the tabs are durable! - the shoulder straps sometimes get stuck when I'm trying to loosen them - one side will loosen just fine but I'll have to pull pretty hard on the other side and it does a little pop before loosening. They are enclosed on the inside of the seat so I can't see what's going on. It doesn't happen every time but I'm wondering if the straps will have a shorter life than the seat (e.g., if the strap is getting caught on something and ends up fraying). - the buckle has a cloth cushion around it which makes it comfy for the kids - it is really hard to remove which is great for not randomly falling off but also hard to take off and put on for cleaning. I'm torn on if I like it or not ... I'm giving this carseat four stars because the LATCH system is even easier than the already easy LATCH system, it has what appears to be top-of-the-line safety features, the fabric wipes up super well, it's easy to adjust the straps/headrest but the weight and difficulty of removing/putting on the cover makes it so it wouldn't be my very first choice/recommendation.

This I'd our first post-infant car seat. I'm thrilled it can convert over the coming years, has so many small adjustment features like tilt and the quality of materials is excellent. It's hefty weight makes me very comfortable from a safety perspective from this early age. The installation is a bit tricky, and we needed several online video searches to figure out the correct setup. The chest strap monitor is nice to have but also not something I would have made a decision based on. I received this car seat through the Stellar Product Testing Panel.

As much as I would love to give this seat a 5 star review, I just cannot. There are a few things I love about it- the fabric is super easy to clean, lots of cushion for soft baby skin, and very comfy especially with the reclining head rest. The seat is customizable and I love that it lasts 10+ years. The side pop-outs for extra side impact cushion is a great safety feature, and it's easy enough to install as far as car seats go. However, my biggest issue is that although the full seat recline helps it to fit in your car, the seat is almost too tall for our backseat. It butts up against the front seat and barely fits- and we don't have a small car! We have a midsize SUV. But for some reason the shape of our car does not mesh well with this carseat and although we're keeping it in there, it means we can't adjust the front seat back any further for now (even when we play with the different recline positions). As the seat is advertised for being super flexible and fitting in any car I have to take away one star because it just isn't the case for us. Thanks to Stellar Product Testing Panel for sending it to us to try out!

Let me start by saying this is my third child and I've purchased at least 8 car seats. This is by far the most luxurious one that we have. It was very easy for me to install using the Latch system and secure it tight in the rear facing position. I think my favorite feature is the reclining headrest. We take a lot of long road trips and I cringe every time one of their heads falls forward while sleeping. My littlest sleeps comfortably in his new Cybex seat and his head has not fallen forward thanks to this headrest. I also appreciate the LSP System on the side facing the door. I hope I never need it, but I feel a little safer knowing it is there to help protect my baby if the worst happens. This truly is the only seat he will ever need. Now I need to purchase another one for our other car, since I'm not sure I want to go back to his old seat. Thank you to the Stellar Product Testing Panel for providing me with this convertible car seat.

We honestly had never heard of Cybex, but compliments of Stellar Product Testing Panel, we were able to give it a try! We received the Eternis S All-In-One to review. It is such a sleek clean design without having random straps hanging and clanking around while rear facing. It is a large seat though, if you have a small car, you may struggle to make them fit. The side impact protection has to be the best known to man. I was in awe of the effort they went to in regards to safety measures, it's beautiful. The head tilting feature is wonderful as well and more beneficial than we ever realized it was going to be. The grandparents are thankful for the large, easy to see release button, as our other one is a bit of a struggle with their older, worn hands. The fabric flows together nicely so there are very few "crumb catching" areas. The largest weakness of Eternis is the cupholder. We always let our kids have water cups in the car and the cupholders are a bit of a joke and have become a toy to our one year old. While I appreciate they are able to pop off to make cleaning easy, they pop off too easily and become a football or weapon in the backseat. All in all, we love the seat and are impressed with the brand, but I'm more than certain my husband will be supergluing or duct taping the cupholder on if he doesn't completely throw it out.

Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat. I tried it out with both my 10 month old ad well as my 3 year old. The seat is easy to install and extremely easy convert from recliner rear facing to straight back forward facing. The reclining headrest is my favorite feature (and works!) because my 3 yo always falls asleep on rides and her head always falls forward. I definitely love the fact that it goes from infant and up making the life of a car seat practical and convenient. I mean who wants to buy one they can only use for a few years because they grow so fast!? I must say that when my 10 month was testing it out, he looked ridiculously comfortable, I almost I felt like I was spoiling him with how cozy he looked! One thing to take note is that when rear facing and reclined, it does take up quite a bit of space so it may not fit into small cars. All in all, love it, would recommend it to anyone and everyone! Thanks again Stellar Product Testing Panel!

This car seat is hands-down, the best car seat I have ever used with either of my children. This all-in-one car seat is incredibly comfortable and roomy for little ones. My daughter hates riding in the car. She usually gets fussy after about an hour. We took a 7 hour trip this past weekend, and my daughter sat in this car seat for the ride. She lasted 4 hours before we had to stop to take a break! I really think all the padding, space, and ability to recline really helped a lot. It also was such a relief and peace of mind to have all the extra safety features, especially the Linear Side Impact Protection. I will say that this car seat is very large and quite heavy. Personally, I love that about it, because it seems so sturdy and doesn't shift around, but I also drive a large car. For a person that has a tight space and other car seats in their car, this might not fit for you. Overall, this is one of the best car seats that I have ever had or seen. I will not hesitate to recommend this to anyone and everyone. It's a major bonus that you can use it for up to 10 years. My 3 year old has already been fighting to sit in it as well. Special thanks to the Stellar Product Testing Panel for sending me this convertible car seat!

The cybex eternis s is the perfect all in one car seat for my youngest boy. He fits very well in it. It's snug but super comfortable. I noticed he sleeps much better in this car seat on longer trips especially with the 3 position reclining headrest which is unique and I haven't seen before on competitor brands. The seat itself straight out of the box was pretty much ready to go short of the latches to connect to the vehicle. I really liked that it was simple to install, has leveling indicators for added safety and stability. The latches felt durable and the handy loops were easy to pull and secure. The car seat felt safe and durable. The side impact protection was unique in this car seat and with a simple push of a button it extends out depending on which side of the vehicle the car seat is at. The harness is well made and very simple to buckle. One of my favorite features of this car seat is that it is a smaller frame on the bottom and gets wider as you go up allowing this car seat to be installed in a 3 in back position in my suv. The comfy material and cushions allow for additional comfort for my child which is a large benefit. I like that this car seat is rated for up to 120 lbs and should allow me to see my child grow in it as I convert it up. Excellent for longevity and durability. The only comment I'd make that was slightly disappointing is that it's a bit on the heavy side. If it could be made from aluminum or fiberglass material maybe will help. Nonetheless excellent carseat and very practical. I like the cupholder as well that can detach and go on either side. The seat was a very nice navy blue color. I received this product as part of the Stellar Product Testing Panel.

The Cybex Eternis S All-In-One car seat is a great car seat! This is our first time using an all-in-one car seat. This seat can be used rear-facing, forward-facing, or as a booster seat depending on your child's weight, height, and age. We tried it with our 18-lb, 26-inch, 6-month-old and he seems happy in it! He was having trouble in his infant seat, possibly because he would get hot and didn't like the angle (we are speculating), so we were eager to try him in a new option. The lower anchor latch release clip is convenient and easy to use compared to other seats we have tried. Installation was complex, but not any more complex than other seats. The height is easy to adjust as the baby grows and the angled headrest will be useful when our child is older. I look forward to trying out the headrest when he's taller. The angle of the seat in the rear-facing position causes it to take up more space than a standard infant seat, so this is something to keep in mind when considering an all-in-one or convertible seat as opposed to an infant seat with a base. You need a spacious backseat for any of these options. Our baby isn't tiny so he doesn't seem to get lost in the seat even though it's big and suitable for a much older kid as well. It's made to fit a newborn as well, but I can't imagine putting a newborn in such a big seat. This seat has a safety feature called "Linear Side-Impact Protection" or LSP, which I had never heard of before. The system is meant to enhance the safety of the seat in the event of a side collision crash. Of course, we have not tested this feature since we haven't been in an accident, but it is nice that it is built-in. The feature has a section that you push and it just pops out so it's incredibly easy to use. My favorite feature of this seat so far is how easily the straps tighten, almost as if they are gliding. Our other convertible seat has straps that are a pain to tighten and loosen. On the Eternis S, the straps easily loosen with the push of a button and pull of the strap. They are also easy to tighten by pulling the strap at the bottom. The idea of this seat lasting 10 years is great, although I have a hard time believing ANY car seat will last that long just due to wear and tear. I do think this seat will hold up well over time. The construction feels sturdy and the fabric feels high quality, but I've also owned other car seats that just get dirty and worn with a couple of years of daily use. Let's be honest, kids and babies are brutal on these types of products! The option of being able to use this seat at multiple stages is great though and for parents who would like to try to use a car seat for a long period, I think this is a great quality option. For us, it is nice that we can use it for our 6-month-old now, but if we decide to move our 5-year-old to a booster, we could potentially switch her to this seat when our 6-month-old is ready for the convertible seat. The versatility is definitely a plus. The appearance of this seat is really nice, too. I did not choose the color since we received this through a panel, but the "Denim Blue" color that we received is a pretty indigo that I would have definitely considered given the choice. It's nice that it's not just black, but it looks modern and sophisticated and nice in the car. Thank you to the Stellar Product Testing Panel for providing me with the Cybex Eternis S All-In-One car seat!

I was given this convertible car seat to try as part of the Stellar Product Testing Panel. I was excited to upgrade my daughters car seat and she really loves her new CYBEX Eternis S All-In-One Car Seat. I love the reclining headrest feature, it's so simple to adjust for when she's ready for a nap and it makes it more comfortable for her as she grows. I also like the lower car seat sides that make it easier for her to climb in herself, perfect for her as she grows into a big kid. This car seat does seem heavier than our old one, so it makes it more difficult to transfer between cars, but we plan on keeping this one positioned in my car, so it works out well and not a big concern. This car seat has all the necessary safety features that is most important to me when picking a car seat and it's also super comfortable for my daughter. We are both very happy with this car seat and I love that it's convertible and versatile, it can grow with my daughter over the 10 year period.

The CYBEX Eternis S All-In-One Car Seat was given to us for free to try out and review from the stellar parent panel. It arrived at the perfect time. Our 5 year old had grown out of her car seat and needed a booster seat and our 9 month old would soon be needing a replacement for her infant car seat. Since the booster we had ordered our 5 year old was delayed in shipping we decided to use the CYBEX Eternis S All-In-One Car Seat as her booster seat for our upcoming three hour road trip. It was PERFECT! Our daughter complains about being uncomfortable during road trips but loved this seat. Never complained and napped comfortably. The headrest tilts forward and back which made it easy for her to nap during the drive. Converting it to a booster was super easy. We love that she's so comfortable and that we know that she's safe and secure in there. The side impact safety is a feature I haven't seen on other booster seats. The fact that this car seat works from infancy to year 10 is amazing!! Really wish we would have had this car seat sooner. It's comfortable, stylish, and safe. The fabric is soft and doesn't get too warm. Living in Houston that is a big plus! I can't recommend this car seat more. Saves you money and the trouble of having to replace car seats to accommodate your growing kiddo.

I had the pleasure of testing the Cybex Eternis S All-In-One Car Seat, as part of the Stellar Star Parent Testing Panel for the last three weeks! I am a stickler for car seat safety, and love the new advances that are coming out. This car seat completely blew my mind. It is a beautiful, sleek, dark blue color (denim blue), and is loaded with safety, convenience and style. My absolute favorite feature is the linear side impact protection . It adds an additional almost 2 inch safety barrier at the head level (door facing) of the seat in the incident of a side impact. Knowing the seat itself is reinforced with steel, and there is this additional feature to keep her safe is incredibly reassuring. As someone who has tried multiple car seats, I love how deep my daughter sits in this seat, and how protected she looks. The three position reclining head rest is great if your child likes to fall asleep in their seat. The seat itself has such longevity and has 12 positions of height. It will last from infant (4lbs!) to preteen. The Eternis S is very easy to install, and you're able to get a nice tight fit. You can pull to install on both sides. It is even easier to remove with the one pull latch removal system. No one likes to fight a latch hook! I found that it was a little difficult to pull to tighten the harness. My big drawback to the seat is the softness of the belts. And while that is also a pro, it is a con for me. I felt that the belts twisted easier as they were a much softer material than others, however, if you lose the pads, it won't leave a mark on your little ones neck. On a side note, it is a little bit heavy, so may not be the best to fly with! I would absolutely recommend this seat to anyone!

If you're looking for a car seat that values safety as a top priority than this is it. Every detail is designed with safety in mind. It's one negative for me is that these extra safety features and soft extra padding make the actual car seat very large. Now for our family situation it wasn't a problem and safety is always the number one concern when it comes to our children. The CYBEX Eternis S All-In-One car seat has some very cool safety features, some I've never seen on any other car seat before. The L.S.P (Linear Side-Impact Protection) is a feature I never knew I needed before but the added protection from side impact is super easy to set up, literally pops out into place and a great peace of mind for kids with car seats by a door. The new reclining headrest feature seems like a fun and fancy feature but really didn't make a difference for my child's comfort and sleep in the car. However, with that being said my kids can sleep anywhere and in the most ridiculous conditions but if your child has more difficulty sleeping in the car this may be something you really love. For us we could take it or leave it. Overall this car seat definitely has a learning curve. The features are top notch and significantly nicer than other car seats I've used in the past. The longevity is outmatched at ten years and so it's worth learning and investing in to make sure your child is safe for as long as they are needing to be in a car seat. So thank you to Stellar Product Testing Panel for providing me with this amazing car seat. I look forward to using it for a many more years to come.

Before this carseat, we had another brand's that was okay for his first year of life, but nothing to write home about. We knew we were quickly approaching the need to level-up and invest in a new carseat. CYBEX Eternis S is a perfect carseat he'll be able to grow with: It's soft and he looks extremely comfortable, well supported and the ability to recline his seat back when he takes a snooze. He's already spilled some food on it and it was easy to spot clean. The carseat fits in the center our our mini-suv comfortably, while still allowing me to sit in the back with him! Lastly, and the most important part, there are several safety features to that, god forbid, we were ever in a car accident, he would be safe in. My only grip, and perhaps it's just me, is that I wish the seatbelt would tighten a bit more. I received this convertible car seat from the Stellar Product Testing Panel

I received the CYBEX Eternis S All-In-One Car Seat just in time for a 9 hour family road trip to FL. This was our first long trip with our daughter, who is now 15 months old so I was very interested to see how she would do and if the car seat would be comfortable for her. Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat for my honest opinion. The first thing I noticed was that the car seat was quite heavy! It feels very sturdy, which I find important for safety. The design is sleek and not bulky. It also does not take up as much room from the front seat as expected. The fabric is smooth and the padding seems plush. Installation was more difficult than I anticipated. I installed it rear-facing, in the center seat of the back seat, using the seat/lap belt. It was quite hard to get the seatbelt into the lock off. The instruction manual could be more clear in how to get it in the lock off (how to maneuver the strap/manipulate it). I ended up getting it in after about 20 minutes of using a "flossing" motion. Since we installed ours in the center seat, we didn't need to utilize the Linear Side-Impact Protection, but that feature is pretty cool to have in case we change the position in the car. Extra safety features are a big plus, and this would make me feel much better about a side impact collision using that feature. Once installed, it is very easy to use. I love that the straps are attached to the headrest so they don't have to be rethreaded as she grows. The magnetic holder for the straps is a nice touch for getting baby in and out while keeping the straps out of the way. The reclining headrest is nice for napping - it definitely helped keep my daughter's head from falling forward. She was able to nap her usual 2 hour naps on the road trip both directions so I would say she found it very comfortable! My daughter can't reach the cup holder yet, so it would be nice if it could be moved closer, but it is large enough to accommodate a variety of sized bottles/cups which is great. When the seat is installed rear-facing, I can't seem to reach the recline adjustment since it is located right up against the seat so that's a bummer. I also noticed that the straps go tightly around her thighs vs the waist so I wasn't sure if this would leave imprints/marks on her legs, but it didn't. I'm excited that we can use this car seat for many years to come as it will grow with her. Overall the car seat exceeded expectations and appears to be very comfortable and will keep my little one safe as she grows.

Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat. I was most impressed with the longevity of the CYBEX Eternis S and it's ability to transform for all the stages of a child's growth with the latest innovation in safety features. My daughter is 2 months old and is currently using this car seat in the rear facing position with the newborn insert. It's easy to strap her in and she loves the comfort of this seat with the reclining options. It feels completely secure and safe around her, giving me peace of mind. As a mom, I especially love the smart features of the seat which ping me if the car is getting too hot or if she's been in the seat for an extended period of time. I think this seat will be even more valuable as she grows with features that alert me if she tries to unbuckle her belt. Overall seat has a sleek design and it is both very heavy and feels extremely secure. This is definitely a seat that will remain in my car now that it is installed vs a light weight car seat carrier that can be affixed to a stroller. I think the value here is really that it can be used for an infant, a toddler and a young child all the way up to 120lbs so once you purchase you are covered for life.

The Cybex Eternis S is the only convertible car seat you will need for your child from 4lbs to 120lbs! It has a unique 3 positioning reclining headrest that made it easy for my daughter to put her head back when she wanted to rest. It prevents that child head forward tilt when they sleep. We enjoy how comfy and luxurious the seat is, it's so thick and squishy! My daughter immediately loved sitting in her seat and enjoyed having her sippy cup in the removable cup holder! The cool side impact protection system, shown in picture two, is also really neat because you push the button when you need it or put it back in if your seat is not next to a window. Other neat features include an adjustable 12-position headrest that moves up and down to size your child. A no-rethread harness, 6-position recline, as well as an in-seat recline feature which allows for extra legroom (and extended rear-facing to 50lbs!) without cramping the front seat! The magnetic clip connector is so helpful to have with a fussy child! There are so many reasons why you need to consider this car seat for your baby or older kid! It really is as great as it sounds! I received this product as apart of Stellar Product Testing to give my honest feedback!

I was really excited to receive this seat as part of the Stellar product testing panel! We were due for an upgrade for my 18 month old's seat and I've heard great things about Cybex products so I was interested to see how it really was. Out of the box, I loved the color and quality of the fabric of the seat and immediately noticed a few things: - places to store the front or rear facing latches for whichever set you aren't using - magnetic spots to hold the bottom buckles out of the way when taking out or putting in your child - the three positioned head recline for little ones who fall asleep All of these features were great! I also loved the added side barrier protection that you pop out depending on the placement of the seat. These will help incase of side impact in a collision and I thought that was pretty neat. Most importantly, my son seamed very comfy and happy in the seat and I can tell it will be great to grow with him. Oh and another thing is that it was super easy to install and get a tight fit immediately! Loved that. Overall, very impressed with this car seat!

I was excited to try this seat for my almost 4 year old. It was easy to put together and seemed like it would be a great fit. My son loves the cup holder, says it's very comfortable and likes the multi position head rest. Unfortunately it is extremely difficult to get a tight fit in our car when installing with the lower latches. I had to have my husband help tighten it as much as possible and even with it tightened as much as possible I'm not very comfortable with the fit. The shoulder straps also twist very easily, which is kind of a pain. Overall it's an okay car seat and I love the look of it, but due to not being able to install safely very easily I don't think it's the most user friendly. I am looking forward to trying this as a booster when we get to that point though. I was given this convertible car seat to try as part of the Stellar Product Testing Panel.

The installation of this car seat is not easy, not logical, and does not fit the seats of a VW Tiguan. Do not buy. For the price this should be better designed.

We've had this seat for a few months now and I love it. The swivel feature is life changing, the magnetic harness locations make putting my child in a breeze and install wasn't that hard. I would like to see a way to lock the seat during transportation, my husband had it swivel back onto him while, and possibly relocate the "lock/unlock" window for the seat. Overall I am happy with my purchase but definitely think for the price it could have felt a little higher end.

I have a really bad back due to a car accident, the feature of being able to get my 9 month old in and out without having to bend and twist in the car is just amazing! She is much happier as well not being in the car carrier seat. She can see better, is more comfortable. I am very excited about this purchase overall!

This car seat is absolutely incredible. It is an absolute game changer for loading your child into and out of the seat, especially as they get bigger and heavier. The safety features and engineering put into this seat give me absolute confidence that I am protecting my child the absolute best that I can in our car. Would 100% recommend this seat!!!

I was really skeptical about purchasing this car seat mainly because of the price. I was captivated by the fact that it swivels which would be extremely helpful for me. As a person that has rheumatoid arthritis and has limited mobility with my elbow and wrists its makes getting my child in and out of the vehicle a lot easier. The Sensorsafe feature was a bit more complicated to set up than I would have liked but now that its set up I think its pretty awesome.

We had a Cybex Aton for our first child and really loved it. So much so that we were disappointed in how fast our daughter outgrew the seat. The Cybex products provide a level of security and confidence that we didn't find with any other brands. We've only been using it a month or so, but the Sirona S is the perfect car seat. Installation was a little tricky, but once it's in it is solid as a rock. The side impact protection, Sensor Safe and load leg provide me with peace of mind that our child is well protected! Having had a Cybex with our first I can't imagine using a car seat without a load leg- the stability is unmatched. The swivel seat makes it easy to get our newborn in and out of the car. I highly highly recommend this seat!

As a person in a wheelchair it was hard looking for the right car seat. The Sirona S makes it so much easier to get my child in and out of the car. I have only had the car seat for a couple of weeks but for me there are two things I love about it. First is the swivel base, instead of feeling like I have to reach half way across the car to put my child in the seat and buckle him I now just turn him around and reach in front of me and do it. I will admit that because of how I am sitting at the car door turning the car seat took a couple of tries to get it to work smoothly but it is well worth the effort. The second one is the one time entry has completely taken away the worry of rushing to find someone to take the time to re-install the car seat for me, and from watching people do it it is not always an easy task. The instillation and setup of the car seat was done by someone else so I have no review on that but I did install and set up SensorSafe. Installation just from my point of view wasn't too hard but wasn't extremely easy. I think it really all depends on your ability to get under a steering wheel and insert the plug in the right spot. Slightly tricky for me but I got it done. After that the app was a breeze to install and get set up right. I didn't think SensorSafe would be much help at first but it has been a big reminder that the back of the car is never the same temperature as the front. Since it's summer I'm reminded that just because I'm freezing up front doesn't mean my child is freezing in the back.

This is a breakthrough for the North American infant car seat market as the rotating seat is just a must for anyone with a bad back or for older parents or grandparents. It just changes the whole process of putting your kid in the car and taking them out again. The only thing I would like to see improved is that several times I have put my baby girl in the car and forgotten to rotate the seat to the backward facing position. There should be an alarm or something to indicate that the seat is not locked in place once the SensorSafe seat lock is in place. Also like nearly every other car seat I have looked at, this seat is Made in China, so the quality of the plastic exterior is not wonderful and my drink holder broke on the first use.

I received this seat for free for testing purposes. I had difficulty installing the seat at first, but Cybex was very helpful with their tips. I specifically had difficulty locking the seat in, in order to install. Even on flat surfaces, it continued to rotate. I feel that a locking mechanism would be helpful for installation. I do love that the seat rotates. It is incredibly easy to put your child in, tighten, and rotate into place. The load arm also works well. I would definitely recommend this seat.

Unfortunately, I received this car seat right before the pandemic hit, so I can't say we're gotten the use out of it that we would like. However, I have been super impressed with it the few times I have used it. My little one had gotten to the point he would resist getting into his other car seat and never has complained about this one. This may seem small, but I absolutely love how easy it is to tighten the straps. I also love how easy it is to adjust the recline and how it can swivel. The major downside is it was a little more complicated to install and it's pretty big so it takes up a lot of room in the car. I would definitely recommend making sure it'll fit in your car before buying it. We have a Prius and my partner is 6'4 and he can't fit in the passenger seat comfortably with the seat behind it. But, if it'll fit in your car I highly recommend the seat

I'm sure other mother's can relate, but when it comes to my baby, I only want the best. I bought a few other car seats, but there wasn't a car seat that I was in love with. After hours upon hours of research, I found the Cybex Sirona S and I am in love! PACKAGING The Cybex came packaged very well and it was tucked in with moldings to prevent any damage during shipping. Car seats are only meant to take one hard hit (for instance if you get into a car accident, you have to replace your baby seat), so I was impressed with the packaging. FIRST IMPRESSIONS After taking the seat out of the box and freeing it from the packaging, I was very impressed with the design and the materials. It's a heavy seat, which typically means the material is good and the weight adds to the sturdiness of the chair. The cushions were plush and soft to the touch, and the color was a very elegant, deep blue. INSTALLATION At first, the installation of the seat was tricky. However, Cybex offers a number of helpful tools to assist with installation (e.g. manuals, online manuals, and Zoom conferencing with an installation tech). I went for the Zoom conference with the installation tech, and they were both friendly and helpful. They first showed me how to install the seat on their demo, and then watched me install mine. They then provided feedback on my installation to ensure the seat was properly installed. Cybex offers a few different ways to install the seat, but they recommended to install the seat with the lap and shoulder belt, so I went with their recommendation. USE This is where Cybex takes a lead above all other brands. This seat swivels at the base to allow parents to strap their babies or toddlers into the seat without contorting your body and twisting your back. You simply push the seat back to the upright position and spin it around. I also noticed that the straps were much easier to put on than the other brands I've tried. Also, the seat has magnets on the side to hold the clips, so you don't have to pull them out from under your child or worry about them burning your child, while placing them in the seat. Adjusting the straps are really easy, so you can make sure your child is securely fastened. Then you simply turn the chair back around, and recline it to a comfortable angle. It's that simple! BELLS AND WHISTLES/SAFETY This seat comes fully loaded with all the bells and whistles. The chest harness is bluetooth enabled with Sensorsafe technology, allowing you to check the temperature of the seat and whether the harness is connected (in case of an accidental unharness by a curious child) through their app. My child loves it when I buckle it and the blue light comes on. The seat comes with a stabilizer leg, which you can use or tuck away, depending on your install needs. The stabilizer leg (if used) provides additional load bearing safety, which makes me feel more secure. I also love that it has these impact wings on both sides, to provide additional coverage and protection for your little one. As I mentioned before, the seats are very plush and can be easily adjusted to fit your child. There are magnets on the side to hold the buckle clips on the shoulder straps, and it has the swivel function. There's not much more you can ask for in a child seat. FINAL THOUGHTS I absolutely love this seat. My husband and I use to fight over who had to put our child in the seat, because it was such a painstaking process, but not with the Sirona S. We simply open the door and the seat is already facing us, welcoming our child. We then tuck our child into the plush cushions, and strap out child in. Then we slide the seat back and go on our merry way. This car seat checks off all of the boxes, and I finally found a seat that I am in love with. When you go to see this car seat in person (as a demo or something), you will see the difference. No more straining my back or twisting and turning to get my child into the car seat. This seat gets a 10/10!

We are thrilled with our Cybex Sirona S car seat. The car seat swivel 360 degrees on its base. This way we can turn the seat towards the door and helps reduce stress on back when lifting child into the sat. It is also convenient as you sit the child facing you to help ease any tension they may have going into the car seat. It also reduces chances of bumping child's head. We are only using rear facing as this point but are looking forward to using the same option with friend facing. The seat clicks when locked into its position but there is also am indicator on the load leg will show when the seat is engaged in rear-facing or forward-facing mode. The load leg is an added feature that helps secure the seat in place. It increases sturdiness of the seat. The seat can be reclined to multiple levels. The seat has a leveler to help recline the child to the correct age and weight. and able to see which recline is appropriate for the weight of child with the label on the side. The leveler is on both sides, so the seat can be placed on either side of the car. The sensor safe feature is an added benefit especially as our child likes to play around with her seat belt. There is a reduced stressing knowing that if the seat belt becomes undone, we will be notified right away through our phone. The L.S.P. system is easy to use with a push of a button and helpful tool to reduce impact to car seat for side impact. The fabric is soft but sturdy. Its robust and easy to clean as our child spills all her meals. Our child appears comfortable in the seat and has tolerated a 3 hours drive without any issues. We are very pleased with our cybex sirona s and recommend it for its safety, workmanship and reliability.

This is the third carseat we've owned, and it's a keeper. As a Brooklyn mom, we are on the go quite a lot -- and escape the city nearly every weekend for a little fresh air. We recently upgraded our carseat with the Sirona S -- and we're never going back. I'll start by saying that this is a heavy seat -- it's not one that can go wherever you do, but we've traded convenience for safety, which is our top priority. Here are the top things we love about our seat: - SAFETY (again, I know). Obviously, safety comes first here, and this seat us one of the top on the market for safety features. The side safety feature is an added bonus. Plus, the stabilizing load leg makes this seat sturdier than the other two we've previously owned. It's noticeable, and the seat seems to rock less. - EASE OF USE. Once installed, this seat is so easy and convenient - it's really easy to get our LO in and out of, without what feels like a full body workout. Seat adjustments are simpler than our previous seats (straps can be extended really easily) and there are a host of functional adjustments that can be made. - LOOK AND FEEL. Though style isn't our biggest determinant in purchasing a seat, this is by far the best looking carseat we've seen. It's quite sleek and stylish (I know this is a carseat here -- it's not haute couture), and we love the blue color. Plus, we've noticed the everyday spills are somehow less visible. The only drawback that I can really point to is the installation process -- which seems to be challenging for me regardless of the seat (let's chalk it up to tired mom brain and lack of handiness). But thank goodness for YouTube, because I was able to follow another user's install guide -- and voila, we're ready to roll!

I got the Sirona S Rotating Convertible Car Seat with SensorSafe for my mom to have in her car for my little one. I thought it would be ideal since it has the swivel seat. My mom absolutely loves and keeps going on and on about how easy it is to get my daughter in and out of the car now.

I was so excited to receive my new seat. It has absolutely exceeded all of my expectations. Pros: The seat swivel is great for getting my little one in and out easily. Installation is tight and secure. The sensorsafe is a fantastic feature. Load leg is nice for added safety. Cons: the chest buckle can be a little tricky to get open. Installation was a little tricky - instructions could be more detailed.

We got this as our "big girl" car seat, so I cannot speak to the comfort for infants, but I really love this seat and my daughter does too! It's stylish and highly functional, and I highly recommend. It worked well for us, but make sure you review the dimensions before purchasing because it is large. Pros: -I love the Sensor Safe technology! One of my greatest fears is forgetting a child in the back seat, and this really puts my mind at ease. Once installed, it chimes as soon as you turn off the car to remind you that baby is in the back. Simple, but effective! -My 1 year old daughter is on the smaller side (20 lbs), but it's still a wrestling match to get her in the car seat. With the seat being able to rotate outward I can easily put her in and get her properly fastened before rotating to rear facing. (I will say this takes some getting used to, but once you're there, it's amazing!) I can only imagine how nice this will be once she's bigger. -The cover is fully washable! However, I didn't find it intuitive to take off, but there are plenty of videos on YouTube to show you how. The manual just doesn't do it justice, you need to see it. Cons: -Keep in mind that it's pretty heavy and I found installation difficult, so I wouldn't recommend if you are needing to move it another vehicle regularly. -Double check the size of your backseat before you buy. I have a compact SUV, and it is tight in the back seat. It easily fits behind my seat (I'm only 5'3") but my husband is 6' and he can't move the seat back to his usual position with the seat in rear facing mode. I think if our daughter were forward facing this wouldn't be an issue. -This is an expensive seat, but if it fits in your budget, the features for both safety and convenience make it worthy of purchase.

I am so excited this swivel car seat is now available in the US! It is a beautiful, sleek car seat, easy install and easy to use, and has many safety features. These are the most important things to me when searching for a car seat! My daughter is turning two in two weeks, and we are expecting another little one soon. I have used maybe 4 different convertible car seats up until now (through our own, and others traveling) and let me tell you why we love this new Cybex Serona S: Easy to use: · Seriously easy to install! We installed with the seatbelt option and it took no time at all, and super straight forward. What I love the most? You can change recline positions without having to reinstall the entire seat! So if baby is sleepy, you can recline back, or if awake or older, you can put them more upright. This is huge! Also, you only have to install once, before changing from forward to rear facing. · The rotating feature is a back saver! This allows you to put in child and tighten the straps so easily without having to bend and twist. This is currently the only car seat available that does this, and it's truly a treat! · The magnetic clips are so easy to use! Other top car seats have buckles that require two hands just to push to open, it can be so frustrating to use these hard buckles, but this Cybex seat is so easy to open and close! The straps easy adjust to tighten and loosen too. Safety: As a mother, my child is my most precious possession. Safety is a very important factor for me when shopping anything baby related. Here are some of the safety features I love in this car seat: · This seems to be the only convertible car seat with the load leg you usually only find on some infant car seats. This load leg can minimize forces from rear collision. · Sensor safe will send notifications to your phone and vehicle receiver when a child has been left in the car, when the car temperature is unsafe, when a child has unbuckled the chest clip, or when the child has been left too long in the seat. · The base of the seat also acts as an anti-rebound panel, to further prevent movement. · Indicators: The lock indicator notifies you that the seat is locked in place, and the load leg indicator notifies you when the leg is properly positioned. · LSP pops out of the sides to prevent side impact Finally, I love how this car seat looks and feels. I would love to be able to get all cozy in a seat like this! I can tell my daughter is comfortable and enjoys the seat. It's a simple, sleek design, with premium materials. This car seat looks and feels great. Overall this car seat is a total win! Super easy to install and use, tons of safety features, and looks great. I am so glad I don't need to compromise on looks for functionality and safety! I highly recommend this seat for anyone out there shopping!

We have been using this seat for the past few weeks and couldn't be happier! It is an absolute game changer. We have a Buick Enclave SUV with 2nd row captain seats and a bucket 3rd row. Our 4 year old is seated in the middle of the 3rd row, forward facing, in a Cyber Sensorsafe convertible seat. Our 2 year old is rear facing on one side in the 2nd and our baby is in this seat on the other side of the 2nd row. Until we found out about this seat, we were starting to car shop. The only way the seating arrangement worked in the past, was because we could get in and out to the 3rd row from the side the infant carrier was on, with just the base, before putting the seat in. Our issue was that once we transitioned her out of that seat, to a convertible seat, we would no longer fit between the seats or be able to make it work. This seat changed all of that! The ability to rotate the seat to the side, is not only extremely easy and convenient to put her in and take her out, but allows us to fit between the 1st and 2nd rows, to get to the 3rd. This literally saved us from needing to buy another car! The sensorsafe, side impact bars and load leg are just amazing safety features! The overall quality, safety, convenience and ease of use make this seat unmatched by anything on the market and worth every penny! It also helps that my daughter absolutely loves her new seat and is always so happy and comfortable. Knowing that my baby has every safety feature possible, makes me happy and comfortable!

This seat is next level. We are a Cybex carseat family and I was so excited for this new Sirona S. We also have an Eternis S, so I was familiar with some of the features that were also on the Sirona S. We have had this car seat for a few weeks now, and while being quarantined at home recently we haven't done as much driving, I still feel like I've gotten enough use to write a review. I love that I will only have to install this once since the installation is good for both rear and forward facing. That being said, I watched videos on installation before I did it, and it certainly looks easier in all the videos than it was to do myself. I installed with the lap and shoulder belt and had a really hard time getting the tensioner to clip in place when the lap/shoulder belt was locked. My husband was eventually able to get it and I am now grateful that this does not require me to re-install. Now that it is in, it feels very secure. Some of the features that I love the most are the load leg base, swivel, the ease of adjusting the headrest and SensorSafe. Having a load leg base is in itself a great feature, but the base also shows you red/green if you are installed securely and also has a lock showing a check mark if the seat is securely clicked in or an "x" if the seat is not securely clicked. This is especially helpful if you utilize the swivel feature and are constantly swiveling the seat back in forth to get your kid in and out. The swivel is simply genius and makes putting your kid in SO much easier. I currently use this seat for my almost 1 year old, however, I also have a 3 year old. When I'm just taking my 3 year old places he now asks to ride in his brothers seat. Both are still rear-facing, but even if he was FF, it would still be incredibly easy to allow him to use this seat with a simple adjustment of the headrest or swivel from RF to FF. Having an Eternis S, I am familiar with the SensorSafe technology. The SensorSafe app was helpful guiding me to where to install the sensor in my car (I had installed the sensor when I got my Eternis S, so I didn't have to re-install). You are able to add more than 1 seat to the app, so you can have multiple seats using the same technology. I have always been impressed with Cybex and this carseat is no exception. It has safety features galore, looks incredibly comfortable and is so easy to manipulate. I can easily recline the seat if I think my son will fall asleep in the car, or I can keep him more inclined if I think he wants to look out the window. The only "downside" that I can come up with is that when he is RF but sitting in the upright most position, there is a lot of "dead space" at his feet. As in, the seat does not sit flush with the backseat of the car, so things can fall down past his feet and he isn't able to reach them. On the flipside, this is likely a bonus if you have tall kiddos you want to keep RF because that is extra foot space for them as they grow. All in all, I love this car seat. The only "issue" was the harder-than-expected install but since I only have to do it once, I don't mind. The safety features and the swivel certainly make it stand out from other seats on the market. We are very pleased with this seat and love that we'll be able to use it for years to come!

Cybex Sirona car seat is amazing. Great quality, easy to use and looking amazing. I'm very serious about car safety and this car seat can keep my little one totally safe. Pros: 1. This car seat looks very cool and stylish. I have it in Indigo blue color that's looking amazing. 2. Easy to install in a car, easy to use. 3. I love the fabric of the car seat. It's seems very comfortable and easy to clean. 4. Car seat have sensor safe technology and looking very safe for baby. Love that I can rotate it in both directions. 5. Have a cup holder. Which is really great. Cons: 1. Car seat is really heavy. Overall I can say that car seat is awesome, I'm happy to get it and would definitely recommend it. My baby feels very comfortable and I feel pease, cause I now that she is safe during our car journeys. Thank you, Cybex for amazing product!

Standout features: • 360 rotation: Our little guy is on the taller side and that has usually made it hard to lift him up and into the traditional rear facing car seats. Add to that the fact that he isn't always willing to get in (grabs on the door frame or kicks the seat back) being able to turn the seat 90 degrees to the door opening makes it so much easier to get him in and out. We will also turn the seat forward facing and he is able to climb in the seat himself. Once he's buckled in, we turn seat to the rear (safest for his age). This rotation feature is great for Grandma who has an even harder time lifting the little guy in and out. • Refacing Recline: When the little guy falls asleep in the car seat, we have the option to recline it while he is in the seat. This prevents his head from falling forward. And then when he's awake, we can adjust the seat more upright to allow him to look out the windows. Our other car seats cannot be adjusted once installed. • Sensor Safe: The chest clip has a sensor in it and the car seat comes with a transmitter that you connect to your car. You and your family members can download the app on your smart phone which shows current info (car is moving or stopped & child's current temperature). The app will notify you and the transmitter in the car beeps if the car is parked and you walk away with the child still buckled in. This feature gives me piece of mind when grandma takes the little guy out. I can check the app and know when they are on the move and would get an alert if for some reason, he was left in the car. • Magnetic: Magnets on either side of the seat hold the seat belt off the seat and out of the way so putting your child in is easier. The way the seat is designed you can also easily sling the belts out of the way. • The super easy adjustable head rest and harness means the little guy will always have the correct fit (no need to wait and find time to re-thread the harness). As with all Cybex products safety and style are the standout features and it's no different with the Sirona S. When looking for a car seat if these two things top your list like it did ours, then the Sirona S Rotating Convertible Car Seat with SensorSafe checks both boxes. However, there are two key features that make life with a toddler just that much easier (the 360 rotation) and that much safer (the sensor safe technology). Immediately you can tell Cybex put safety at the top of their list. The car seat Is very substantial. Out of the box you can tell it is very sturdy and quite heavy. It's meant to stay in place once installed. While the installation was straight forward and easy, I wouldn't suggest moving the seat from one car to another. I had a tough time with one of the installation steps and had to ask for help. The Latch system was easy to engage, but I couldn't push and lock down the belt tension arm. It takes a bit of hand strength, but once installed you don't have adjust it anymore. We installed it behind the passenger seat in a Chevy Bolt 2017 and it fits easily. It has a somewhat narrow footprint but the chair itself it wide which makes it very roomy and comfortable for our 21-month-old boy who is on the bigger side. The high-quality fabrics/textiles are soft and luxurious adding to the comfort. This is one of the only convertible car seats that still has a load leg which I love. The button to release the harness and the chest clip are a bit tough to press but I've noticed that with other car seats as well and gets easier over time. If you have weakness with your hand you might want to test this out before buying. You can also purchase one of those "car seat keys" to help. Overall the safety and the features listed above make it an outstanding car seat if you have the space in your car. Definitely recommended.

Pros: SironaS seat has very nice material and padding, feels very comfortable for my daughter. Love the adjustments that can be made as she grows and the ability to rotate the seat so I can easily get her in and out. I have midsize sedan, so getting in and out of the car is a hassle. Feels very safe, the harness and interior padding is a plus. Easy to install. Really liked the upgraded feature of the SensorSafe, gives me peace of mind knowing the temperature is good and my daughter is not left in the car. You can also add anyone else to receive the alerts, so they also can have peace of mind. App install was easy, and user friendly. Cons: Its sooo heavy and bulky. Don't expect to move this seat on a regular basis. Sensorsafe- I don't like having my location turned on all the time, so that is the drawback for me. Pricing is high

I was so excited to receive this car seat and was eager to get it installed. It has so many amazing features and safety devices within it. I had seen the European versions of these seats online and thought the swivel concept was fantastic. I have scoliosis and along with that comes some pretty bad back pains. This car seat can easily swivel to turn it to the side and be able to load your child in and out without twisting your back. This is huge for me and I'm sure many other parents out there. I also loved the extra protection that comes from having the load leg safety protection. I found this car seat was very easy to install and I used the latch hooks. I love how I only need to install this once. I currently have a 7 month old and a 3 year old so technically they could each take a turn riding in it without doing separate installs. The headrest is easily adjustable as well. Another one of my favorite features in this seat was the magnets on both sides of the seat that holds the straps so there is no more scrambling underneath and behind my child to locate the straps. This is especially helpful when your child is not so happy to be placed in the car seat! The Cybex Sirona S is also equipped with SensorSafe technology on the chest clip. This comes with a receiver that is plugged into your vehicle and then you download the app onto your smartphone. This amazing technology will let you know through the app if your child is too hot, if they unbuckled themself, or if they are left in the car too long. I personally think all car seats should be equipped with this in order to prevent many accidental child deaths due to overheating by being left in the car. My absolute only negative about this seat is that it is rather wide and I am unable to have my older child's convertible seat right next to it if I want to utilize the rotating feature. This is really not a huge deal as I just have to place it in another spot within my vehicle. All in all, this seat is absolutely amazing and I am looking forward to be using it for a long time. It is going to be so helpful especially on the days when my back pain is bad and I need to get my child in and out of their seat a few times. This seat has amazing safety features and there is no doubt in my mind that my child is riding as safe as can be. I will be recommending this car seat to everyone I know!
