I'm really happy with the flexibility and technology of this car seat. The safety features are excellent and it's been a huge upgrade from our previous baby-specific travel system seat. We especially love the easy-in-and-our function that allows you turn the seat to the side, that's been a game changer in our vehicle. The safety features are so critical, and give me peace of mind. Really appreciate the thoughtful design and tech innovation that went into this car seat!

I have been obsessed with this car seat since I saw it in my cousins car in Germany. It makes taking my daughter in and out of her seat such a breeze. It is the only car seat in the US with the swiveling technology. It also feels incredibly safe and makes me feel secure taking my child in the car. It's also aesthetically nicer looking than most other car seats out there. I LOVE this seat and highly highly recommend it to all parents. Safety, ease of use, aesthetics, comfort - it checks all my wants and needs. Cybex exceeded all expectations with this seat

I am in love with this car seat!!! It's is so comfy and cozy for my big nine month old who outgrew his infant carrier by the time he was six months. I needed a convertible car seat for him already. This one is great. Infant stage all the way to big kid! So you only need to buy is one car seat and save money this way. This car seat has an extended pole that pressure woo it's in the car's floor for added stability and security for safety. The most greatest part of this car seat is that it rotates for easily to get your child in and out especially when they are smaller to take out yourself. Very easy to install in my Chevy truck. I really feel my child safe in this car seat due to its durability and the side impact features. Can't wait to use this more for our frequent road trips I am over the moon with this new gear and will totally recommend this item.

I have been using the Cybex SironaS rotating convertible car seat with SensorSafe in my 2011 GMC Terrain for a couple of weeks and it has exceeded my expectations in regards to style and safety. My son usually whines after sitting in the car seat too long but this seat has proven to be comfortable and he has not complained since we started using it. Pros: - Installation was simple with Isofix system and it is optional to use the bar depending on your cars setup. - Safety features include SensorSafe which hooks up to your cars computer system and makes a noise when you park and the seat is buckled or if unbuckled when the car is moving. SensorSafe can also be easily connected to an phone app which gives the temperature of the car and status of the seat (ie. buckled or unbuckled). - Easily able to swivel the seat 360 degrees, great if you need to rotate the seat toward you to place your child in the seat with ease. Also great if you are using the seat for different age kids and want to quickly make it forward or rear facing. - The material is soft and can be easily wiped down; cloth portion of the seat can be removed and washed - Leg room when rear facing - Spacious seat with great head support Cons: - Somewhat bulky, can only fit 2 car seats in a row with not much space between. - Only for usage up to 65 lbs Overall, I would definitely recommend the Cybex SironaS car seat. The safety features and quality of the seat are unmatched and both my 5 month old and 2 year old appear to be extremely comfortable.

This is really by far the best carseat ever, no doubt about it. You can always be sure it's on properly, so that's one less worry. When you are alone with the your baby and they won't stop crying you can turn them real quick to give them their pacifier and turn them back to rear facing. This is a genious idea. I saw the struggle other have with a normal car seat, this is safe, baby looks super confy and secure. This is seriously a must have for all parents.

We got this car seat to be used as both a rear facing and a front facing car seat for our little guy! He's kinda on the short size due to him being born 3 weeks early and only weighing 4 lbs at birth and now he weighs a little under 20 lbs so he's not big enough or to sit front ways just yet and he's pretty short so we needed something other than the car seats that you carry around due to it getting pretty heavy with him in it! So we needed something that we could just mount in the car and leave it! And we sound this car seat and we absolutely LOVE IT and it is so cool to use we love the way it looks and the 360 degree feature that you can turn it from rear facing to forward facing with a push of a button this is a great buy!!!

The product arrived in a box that was clear of what it was. This could be problematic if you live in an area where items are taken off your door step. However, this product is heavy and by myself I was not able to move it without the assistance of my husband. The shoulder straps/ clips clip very easily and release easy when pushing the release button which is easier than a previous model that I had tested. The device to plug into your car is beneficial especially if you are a new parent and often rushed with the tasks of everyday life in order to ensure you do not forget your little one in the car. The fact that this car seat can be used from 6pounds to 65 pounds is amazing. You can literally use it from newborn up. However, it is problematic to have to take the infant out and carry around if you do not have them in a car seat with a removable base. Many car seats go up to 100pounds and for this reason I gave it 4 stars. It is also pricer than many car seats that do go up to 100 pounds and for this reason is not as cost effective as others. The installation is more difficult than another car seat we have. However, after completing it a few times it does become easier and easier to install.

About installation : It took me about 20 min to install the seat. I had to use both system to attach the seat. Seat belt and adjusters. Instructions are easy and clear. You just need to check out the instructions on the car seat back panel and repeat few step instructions. About usage : Super comfy and roomy. My 1 year old daughter loves it. Baby is easy to sit in by using the rotation seat feature. Security : As you can see all the features, functionalities for that car seat are baby and security centric. Your baby feels really safe. Sensors and app are a good plus I did not use much so far. It alerts you when the seat belt is suddenly unlocked and such things. Quality : Seat materials are really good. We had the Cybex Cloud Q before and this one is as good and as safe as the cloud Q.

We've had this seat for a couple weeks and we love it. It's very easy to install and the anchors are easy to get in and out. I haven't used the sensorsafe feature yet but I think it's a great idea but I'm not really a big fan of the leg.

I fell in love with the Cybex Sirona after seeing Kim Kardashian use it for North (in KUWTK). It was super sleek and looked like a very robust car seat. Stylish but practical- like it would be affective and really protect the child in the event of an accident. Now with the new model S, they really did think of everything. I love it and my toddlers seem to love it. I used to bump my daughter's head on the top of the door opening every time I put her in the rear facing car seat. With this one, she snaps on easily facing me and the seat just glides right back into the rear facing position. She used to fight and wrestle with me getting into her car seat. And even though she still does sometimes (lol), it's so much easier to get her strapped in while she's facing me instead of trying to do it sideways through a small opening. And I absolutely love that you don't have to reinstall the base if you want to switch it over to forward facing. Omg sometimes it takes me an hour+ to learn how to install and actually install a car seat correctly- especially when there's different instructions to install it forward facing or rear facing. The base has a stability leg so it's pretty safe either way you flip it. Overall, the quality of the car seat is excellent. Everything works/snaps/glides so smoothly. It's definitely a luxury product and I feel that my children are absolutely safe in the Sirona S. My only complaint is that I can't fit 3 car seats in a row in the backseat, but then again I guess very few car seats can.

I was a certified Child Passenger Safety technician for several years and have installed many different car seats in many different types of vehicles. I have only tried the Sirona S in my vehicle (Toyota Prius V) for my toddler (25 months 30lbs. and 33.5" tall). I installed the Sensorsafe app on my iPhone, it works well and the setup instructions within the app were easy to follow. I love that you install this seat using the same belt path for rear or forward facing, less things to have to remember! I highly recommend the using the seat belt to install this car seat because it was easy to get a tight install with the seat belt and you must cease using LATCH at 30lbs rear facing and 35lbs forward facing, just more things to have to remember. I really like the lock off in the base (the bottom of the car seat is called the base, but the top part does NOT come off like an infant car seat) it was very easy to feed the seatbelt through and lock it down with the Easy Lock lever, I did not have to put my weight in the car seat to get it tight. I like the pull strap release on the LATCH buckles. The rotate feature is my favorite feature by far! My 25 month old can climb in by herself when the car seat is rotated to face the car door. I hurt my back from lifting the toddler after having my second baby. The most difficult lifts I had to do with her were getting her in and out of her rear facing convertible car seat. If I had this car seat back then it would have really helped, maybe even avoided the 10 weeks of physical therapy I ended up having to do. Be aware that the user manual requires the top tether to be used forward facing (and you want to use it, it greatly reduces head movement in an accident), the rotate feature will not work unless you detach the tether each time. This is not huge negative for me because I plan rear face until at least 3 years old, by that time she will easily be able to climb in and out of the car seat without rotating. When I checked out the seat in the house I was very excited to see how upright the seat can sit while rear facing. I thought my toddler could sit upright and have lots of leg room and see out the window better when she is awake and I could easily recline the seat more when she takes an occasional nap in the car. When it is installed in my car however, the only positions that can be used according to the level indicator are the 4 most reclined positions. There is not really any more leg room than with our other convertible car seat and she is at about the same recline. I only had to move my front passenger seat up one notch to allow the Sirona to recline fully for a newborn, it is very unusual for such a large seat to take up so little front to back space! For forward facing, only the most upright position can be used in my car, the level indicator was barely in the red zone (red is for forward facing, blue is for rear facing). Pros: -A load leg and L.S.P on a convertible car seat! -Looks like it will work well for a small newborn -Does not take up much room front to back even in the most reclined position -High rear facing capacity, 4-50 lbs. and 17"-49" -High forward facing capacity, 22-65 lbs. and 28"-49" -The headrest adjusts smoothly and easily up and down -Very well cushioned and comfortable for babies and toddlers, when I press the seat bottom cushion with my hand I can't even feel the plastic through the very thick cushion -The harness adjuster moves very smoothly and easily when loosening or tightening the harness -Retractable L.S.P. only takes up extra width in your car when in use -LATCH strap pull release mechanism is easy to use -Clear, easy to understand user manual and stickers on the car seat -10 year expiration date Cons: -The chest clip is stiff to buckle and unbuckle, this may get better with use -Only 5 of the 12 recline positions are usable in my car -The rotate feature isn't really useful in forward facing mode because of the top tether -The user manual is clear, but very long with many rules for using the different features, it took me several days of spare moments to read the whole manual, it is a little overwhelming -Not certified for use on aircraft, this is not a huge con, I assure you that you do not want to lug this gigantic car seat onto a plane I recommend this car seat for a newborn or a toddler! I used an infant car seat for both of my newborns but the Sirona reclines enough for a newborn and would still allow an adult to sit comfortably in front, I will definitely consider it for the next baby! I think the rotate feature is especially useful with larger rear facing toddlers, they are so heavy to lift in and out. I received this car seat for free in exchange for my honest review.

This carseat is truly so convenient. I love the ease of putting my son in and swirving the carseat back to rear facing. It's extremely cushioned but doesn't seem to make my son sweat so that's a plus. The carseats appearance is very elegant, the stitching is nice, it looks extremely well made. The only issue I had with this carseat was the installation. It took me about 2 1/2 hours to install and a few times going over the manual. You just have to find what works for you when it comes to installation. The mounting post did not work for my car so I don't use that feature but all in all it seems very secure and hardly moves. My son overall loves it and seems so cozy.

Honestly this it's the best car seat I ever had for my kids I love it and works perfectly for mi family because I don't have to re-install every time I have to use it either for my toddler or my baby I just install once and that's all honestly this it's he best!!!! I highly recommend this car seat

It came in the mail two weeks ago. I ordered it maybe two week before. So far I love the style of it, it's nice and heavy. The best part I love about it is, you can turn it around and punch from infant to toddler.

We had over 5 carseats (all from different brands) so far and this is by far the best carseat we've ever had! Pro: - the belt is easy to put on and easy to adjust the length - baby's head does NOT move around! (we had this issue with some other carseats) - baby is very comfortable and happy in it (he doesn't complain) - it feels very safe and sturdy - I love that we can technically adjust the carseat positions and move it 360 degrees. - I love that my son can grow in this carseat. It manages wide range of height and weight. - love the design! Looks very high quality. Con: - compared to other carseats I have owned, it was slightly more complicated to install but its easily managed if you watch their manual video - heavy - it may be heavy for a single mom to carry it - I still have a hard time moving the carseat 360 degrees.

Installation: We installed the carseat forward facing with lap and shoulder belt. It was very straighforward and simple EXCEPT the instructions for the belt lock feature were lacking (no pictures, no instructions on how to put the belt in, and I'm pretty sure you don't need this feature if you have a seatbelt that locks). We ended up not using it. Features: The cupholder is pretty dinky, you just slide it on one of the sides and it does not seem like it will hold up to toddler use, and it is oddly slanted (using recline 5). I love that the shoulder straps move up with the headrest and do not require re-threading. This makes it VERY easy to resize as your baby grows. I also like that there is a storage compartment for the top tether belt if you were not using it. The Linear Side-Impact Feature sounds like a good added safety feature though I hope we never need to know. Overall this seat seems comfortable for my son, easy to us on a day-to-day basis

This car seat is great for infant to toddler. I have a 4 month old daughter that I used the car seat for 2 weeks. It was great for a permanent rear facing seat. I really enjoyed the Magnetic Buckle Holder!!! Having a small child and having to place in the seat is difficult and especially when the straps lays under them. I also used this seat for my 3 year old daughter. She was in love with how roomy and comfy(squishy) it was. The adjustable head rest was nice for her. Also being able to position the car seat to be specific to your child is very helpful in taking long car rides. NO NEED TO ADJUST THE HARNESS just slide the headrest!!! Super quick! Also easy to install LATCH system but EASIER to remove with the one pull red strap. This is my 1st Cybex brand product or even hearing about the brand. This car seat has really opened my eyes on what nice quality details and safety features Cybex offers.

We love this carseat. We are foster parents and have been on the hunt for a safe reliable carseat that could comfortably fit a large age range of children, and the Cybex Eternis S fits the bill. For a carseat that works from infant through 120 lbs (WHAT??!!! thats AMAZING), its affordable and stylish and comfy as all get out (I wouldnt know, but the kiddos seem to love it). My favorite small little detail about the Eternis S are the magnetic seatbelt clip holders- this has been a lifesaver when transfering a sleeping baby without waking them by having to pull up the seatbelt straps from underneath them. And it was SO easy to install! We started with a cybex infant seat and trust the brand, and have upgraded to this all-in-one Cybex Eternis and we wont look back. We are Cybex fans for life!

My family got this car seat a couple of weeks ago and we are already so happy with it. I needed a car seat to put in my husband's car that we could use with my 3 year old but also with my 5 month old. This car seat can be easily switched from being forward facing in a more upright position for my toddler to being rear facing and inclined at the right angle for my infant. The look is amazing and completely sleek looking.

The most important thing about an infant/child's car seat is Safety in my opinion. The Eternis is made extremely sturdy and all of the parts on this car seat glides/snaps smoothly and seamlessly. You can tell that they did not skimp on a single detail- including the packaging box that it comes in. (I've had other car seats delivered in a loosely packaged box without any foam protection or padding that keeps it in place. So the box is not only bent but the car seat inside it has been tossed/bumped around!) So the attention to detail not only makes me feel like I have a high quality product, but it gives me assurance that the car seat is going to hold up and do it's job in the event of an accident. I love the LSP (Linear Side-Impact Protection) that is built into this seat too. Even though the middle seat is supposed to be the safest to put your car seat in, the LSP seems like it would give extra protection that my previous car seats didn't have even if it's installed on the outer sides. I have two different car seats installed on each side of my backseat. And honestly, it's tough deciding which child to put into the Eternis because I feel like I'm favoring one child over the other and in the event of a car accident, the other child may not be as safe. It's so stupid and silly but I really do feel that way and I'm thinking of buying another Eternis and donating my other car seat because of it. LOL. The only drawback I could see about the Eternis though, is the size/width. You really can't put 3 car seats in a row with this. However, 3 in a row is hard to do with most car seats and I think the Eternis is more for people who are looking for Style and Durability or Safety. Not necessarily Space savings or Lightweight/Travel friendly. So just think about what's more important for your specific needs before you make a decision.

We've had this seat for about a month. I was AMAZED at the attention to detail. My favorite feature is that everything has a built in storage area. Especially for the user manual! It fit's right in the back compartment. Same for the back latch, and for the latch system. I also love the weight of the seat. It feels like a safe place for our little ones.

I have had this car seat for about three weeks and so far I love the look, features and my daughter seems to be more comfortable in it than her old car seat. We went on a road trip and she did not fuss which is a big win for us! My initial thought was it was sleek and modern, so much my husband instantly wanted to switch out seats with me and put it in his sports car. I love the soft padded material around the shoulder supports and leg buckle. I was also impressed with the back support that automatically adjusts when you pull the head rest up and down. This seat also has Linear Side-Impact Protection which is hard plastic that can be set on each side and is designed to absorb impact during an accident. Installation was a bit difficult. It took about 30 minutes to install the first time and that was after reading the instructions. The issues I ran into were understanding the proper routing for the lap/seat belt for the rear facing configuration. The seat was loose and it took a moment to figure out how to route the belt through the belt locking feature. Subsequently, the seat was extremely easier to install.Once installed everything was easily adjustable including the tilting mechanism and moving the headrest. Overall, I love the car seat and would definitely consider purchasing this seat for my next child. It is definitely top of the line and superior in many ways. Pros: The seat sits firm and doesn't slide around in my vehicle (GMC Terrain). Spacious seat Shoulder cushions are comfortable Cup Holder easily clips to either side of car seat Cons: Initial installation becomes labor intensive due to ambiguous directions. The buckle across the chest is a little hard to unclip which may ease up over time. Material is not removable (spot cleaning can be difficult)

I have been using this convertible car seat for a few weeks now and I am so glad I went for it. I'll start by saying that it is a very well made car seat and of course it is heavy, but that only makes me feel safer while driving my toddler around, and once it's installed is not going anywhere. It has a lot of padding and seems very comfortable, even the buckle has some around it to avoid marks around my babies thighs when she wears shorts or bathing suit. The adjustable head rest makes this car seat extra safe! It reminds me of a race car and how protected their head must be. I picked black color and it might be slightly "boring" but I like how you can't really tell there have been some water spills, and it is easy to clean. It took me a little while to learn how things work (I am slightly technology impaired) especially with adjusting the head rest and making sure it was in the right position, but once I got it it was great. The straps slide very nicely as well and the small places to hook them are such a nice feature!! So helpful when you have a sleeping baby that you need to put in or take out of the car! Overall, this car seat has everything you need and nothing you don't. Plus did I mention how safe it is?

I really really love this car seat! My 2.5 year old is so comfortable and actually loves sitting in it. I think my favorite feature is how easy it was to install. He is still rear facing, and I hate struggling to get the car seat hooked to the tethers. This made it so easy to switch between cars and get a good tight fit every time we had to install it. I also loved that you can access the tethers by unsnapping the lining of the car seat. It made it so easy to thread them through properly and make sure they were not twisted. I also really love that it offers a head recline. We have not used it much yet, but when my youngest gets a little bigger, and out of the infant seat, I can't want to have that option for her so she does not slump foreword! It is easily adjustable, and very easy to get the right fit/recline in the car. I would highly recommend this for ease of install, ease of adjustment, and the comfortable feel for my kiddo!

We have the Cybex Gold Eternis S All in One Carseat in Lavastone. I feel that Cybex thought of EVERYTHING when they created this product!! The installation of this carseat was so simple! My husband and I were able to install it together in about 10 minutes tops. One thing that really sticks out with this carseat is that my child can rear face up to 50 pounds! That's a huge deal for me as children and safest rear facing! I love that my child has so much room in this carseat and is still safe with the linear side protection and the steel base (the highest in safety quality). Some other amazing features of this carseat are the tilting headrest so that my daughter's head doesn't flop forward when she falls asleep and the magnetic holders on the side for the safety clips. This carseat is top notch and WELL worth the investment!

This carseat is amazing, it came all together and ready to go. I will say it is heavy but totally fine. I had it installed in my Tahoe and it worked wonderfully. I do like the L.S.P. system which puts my mind at ease for safety if anything was to happen. I love the color and fabic was soft. Im happy to know it has a ten year life span which is great. A all in one for all stages of my childs life. I even liked the fact it came with a cup holder. Adjusting the seat in the car was easy to do, plus, it had a leveller for adjusting to where it needs to be in safe zone. I definitely will recommend this carseat.

I decided to use this seat for my 7 year old because of the tilting head rest. My son fits well in this seat and he told me it is more comfortable than his previous high back booster. The tilting head rest is so nice for him to be able to sleep in the car. What's nice value for a convertible car seat from basically birth to booster. The only thing I would change is add a ratchet system to install it.

This is a very well made car seat. It is heavy, but sturdy and the fabric is soft, good looking, and no piling yet! The headrest and straps are very easy to adjust. The straps glide smoothly and it's super easy tightening or loosening them. With the headrest in the lowest setting the seat back folds and sits awkwardly in the seat. As the headrest is raised the seat back fits much nicer. I achieved a good fit for my 9 month old. The seat doesn't feel very padded- the seat back actually feels a bit hard but my daughter falls asleep in it so I imagine it isn't that uncomfortable. I love how easy the belt install is in my car. The multiple reclines, level, and labels on the seat made it quick and easy to install (rfig) first try. Hoping ffing will be the same!

This car seat is so sleek and has many features! I absolutely enjoy the love the sensor safe harness and could not do without it. It's very easy to adjust and will grow with my daughter. This seat can be used from birth until booster. The material is high quality and looks very easy to clean. Overall this seat is really awesome and has many quality features!

I currently have the Cybex Cloud Q plus infant car seat and was looking to upgrade to a car seat that could stay with my little one throughout his years. I am consistently drawn to the Cybex brand because of its powerful combination of safety and design. The Eternis S has both, and I found it easy to install as well as safe, comfortable, and stylish. I installed the Eternis S using the latch system and rear-facing option. The latches are in a compartment underneath the seat and the instructions in the booklet were easy to follow, esp. the visuals. I also like that there's a device on the side with a bead so you know you've installed it correctly (e.g. the recline) for both forward and rear facing options, based on your child's weight. The linear side protection was so easy to use (just push a button!) and is an added element of safety. Beyond the ease of installation, some features I enjoy include the following: the reclining headrest so that baby/child's head is back with airway open; the soft padding; and the ability to remove and wash the upholstery on the seat. My one criticism is that for the seatbelt, particularly the bottom buckle, you do need to have one hand on the front and back to forcefully push the red button so the belt releases. Overall, it's reassuring to have my child in the safest car seat while also turning heads with the Eternis' innovative style. I look forward to transitioning to the forward facing option when my little one is big enough, and having this car seat for the long haul. .

I've had 3 children, and went through a few carseats, I can honestly say this is the best carseat I've ever owned! It has such a nice amount of padding! Makes for such a comfortable car ride! I got it for my son who just turned two so I have only used this forward facing. Feels so sturdy and safe! The head rest tilts back so when hes asleep his little head doesn't flop forward, like it would in any other seat! I like that the cup is removable, so it's easy to clean or choose which side to put it on. Although, if I had one complaint I wish it had the cup connected to the front of an arm rest. Only because I have two seats next to eachother and there isn't much room for me to squeeze the cup on the side by my daughters seat. The feature on the bottom to make sure the seat is at the right angle is so nice and easy to use! It was super easy to install. love the side impact safety as well! My daughter who is 4 sat in it and was like oh my gosh mom this seat is so comfortable, I want to trade lol I definitely recommend this carseat!! I recieved this carseat in exchange for an honest review.

We are loving this seat so far! My son says his favorite part is the padded lower seatbelt - I think that the bottom part of car seat seatbelts can be very uncomfortable for little boys, and this one has a nice soft padding to protect. I was able to install it very quickly, and get a secure in style. The seat is sleek, and easy to buckle. I love that it can convert to the high back booster, which we will be doing in the next several months.

I love this car seat!! The first thing I noticed was how soft the fabric is. It appears so comfortable and luxurious. Although heavy, the seat was easily placed in the car and adjusted for my 15m old. The level at the bottom made it easy to ensure it was adjusted properly. My baby is very comfortable. The wings in the head make a little car nap easy with no "head bob". The design of the seat is also great with side impact safety features and has a firm fit on the 5 point harness. I would definitely recommend!!

Purchased this as an additional seat for another vehicle. Seat is very high quality and easy to use. All belts and latch system are very smooth and easy to operate. Seat is very comfortable and our daughter loves it upgrading our other seats to this model.

I have a 4 mo baby, and had a Atom M2 carseat, witch baby does not like at all, so I change to the Eternis S. He Love it, now he can go on the car without tears! chair looks so comfy and deluxe!!! For real, we went from "economy class" to "1st class" have a lot of positions and is very easy to use.

The Cybex Eternis S All-In-One Convertible Car Seat is going to be the only seat my 3 month old son will ever need because it grows with him.  It moves from rear-facing to forward facing to a booster seat as he gets older. The car seat was fairly heavy due to the steel reinforced frame which gives me a peace of mind knowing that if I am in an accident that I have one of the best durable materials surrounding my child. This seat came with an additional protection function called Linear Side-Impact Protection (LSP).  It was an easy to push button on the side of the car seat which then popped out a hard piece of plastic toward the door which is designed to absorb up to 25% more impact forces in an accident. The headrest in this seat had 12 different positions!  I always worried with my first child that her head would bounce around and fall to her chest once she fell asleep.  Using this seat for my son I can worry less because it has all of these positions that you can set the headrest at.  Some settings are designed at these inclines especially for when they fall asleep. It was easy to install using the anchor clips and that they click released.  The tightening straps could be shortened or lengthened effortlessly.  I did find that the labeling could have been better in the manual/on the car seat because I was looking for the exact words of rear facing belt on the car seat to slip the seat belt through and I was not able to find it.  The headrest was a bit difficult to adjust at first because you have to pull up on the release and push/pull the headrest at the same time. After a very long day of car riding my son seemed to nap well in the seat and not be as fussy during awake periods due to all of the extra padding and positions you can have in this car seat.

The Eternis Car seat is a great car seat. I feel like this car seat is so Solid! The added safety features like the linear side impact system are great for peace of mind. One of my favorite features is the magnetic strap holders. No more having to dig for the buckles or hold them out of the way while putting baby in the seat. The reclining headrest is also nice but not usable during the smaller infant stages so I can not tell you if my child likes it or not. The aesthetic of the seat is very sleek looking. Really the only cons to this seat have to do with the harness. I felt like the buckles were a bit cumbersome. They work, don't get me wrong, but It takes a little more effort. Also the tightening strap was awkward in the rear facing position. The opening was too close to my car's seat and made it difficult to pull. Those are really only minor things though. Overall I think this is a fantastic car seat

This car seat replaced another that we had. My child is EXTREMELY comfortable in it. She now is willing to take longer car rides. It is also very easy to get her in and out of this seat, which is nice. It has some nice features that I like and some that can be better but we have no real issue with. Pros: The magnets that hold the buckles up are very useful. The easy in which we can tilt the seat is nice. The pull-through to tighten the latch buckles made tightening it easy. The button to loose the straps is the best we have seen, most are either difficult to find or press the "wrong" way, this one makes loosing the straps very easy and removing my child from the seat very easy well. When the head rest goes up it adjusts the straps automatically. The head rest tilts forward and back, which greatly aids to my child's comfort. Cons: The head rest is a bit wobbly, but I am not really worried about that. There is no way to remove the seat cover, so cleaning it will be difficult. Somehow the straps came loose and I had to retread them to through the seat, I think this was just bad luck though, I was able to do this with relative ease. Overall: Not being able to remove the seat cover to clean it might be an issue, spot cleaning it is easy enough though. If you can live with not removing the seat cover, then this is a very nice car seat that we expect will last for many years. We are really happy with the comfort, which is top notch and the features like the magnets to hold the straps and the button to loosen them are a real plus.

I've had this car seat for about a week and it's such an excellent car seat! My 2 year old actually enjoys sitting in his car seat and I can see that he is comfortable. The safety features are excellent. The belt clip is easy to use, easy to get my son in and out of. The sensor safe app is helpful, but something we have to get used to using since this is the first car seat that actually has an app. Installation was a little difficult, but we eventually figured it was my car's latch system at fault. I drive a midsize suv and the Eternis is a little on the big side, but there is enough space for 2 passengers in the back. I'm very happy with this car seat and it's features. This car seat exceeded my expectations compared to the other brands that I've tried! Thank you Cybex!

Fits very nicely in our Subaru Forester, was very easy to install and get nice and tight using the latch system, both sides can be tightened and I like that a lot. Feels very very sturdy and our daughter fell asleep on the way home the second time she road in it so it also much be very comfortable!

This is a high quality car seat that will last through each stage. It's well made, and has cool features like side door impact protection, a cup holder my kid can reach, flexible headrest, comfy padding and a nice shape, etc. my only downside is that it's super heavy- not a travel car seat at all- this one will live in our car and we got a cheap, light one for travel.

I got this car seat this week and am amazed as it truly does meet the needs of my children from rear facing to booster. Most important it is easy to transition and install. The seat fasteners are quick and easy as they can be easily hooked and unhooked. (All I have to do is pull on a cord and they come undone no more pulling till I can't feel my fingers.) This latch system should be on all your seats! I love how how I don't have to remove the harness straps to transition it to a booster and it is still comfortable at the same time. My children love the seat and have been fighting over who gets to sit in it.
