I loved this car seat, however I have a 4Runner and it did not leave a lot of floor board space with the leg extended.

Cannot reccomend this enough. Loved it so much we bought a second for our second car. I will say it is a little difficult to instal but otherwise we love it.

We are grandparents to a hefty 15 month old. Grandma has back issues and grandpa dementia. This car seat has made sharing time with our grandchild a snap. I do not have to twist my back to clip him in a car seat. It is outstanding. It is a pleasure knowing that technology can make such a difference when people have back issues. LOVE IT. RECOMMEND IT. BUY IT. It is worth every dollar of investment made.

This was the first car seat I’ve purchased that wasn’t a britax. Even after taking it to a car seat technician I’m just not comfortable with how It feels installed in comparison to britax. The chest clip is also very easy to undo… so be prepared for o your toddler to undo it 437 times on every ride.

We bought two of these car seats, and it has been such a breeze to installing and using over the past two years. I will also say for a majority of the comments that state it was difficult to get a secure fit, you are supposed to check for a 1 inch wiggle at the base where either the latch or seatbelt is used(not check the shake towards where the head rest.) I would also say the main reason with why we bought this seat was it being the only convertible available with a load leg

Not so great install, very bulky, pads didn’t hold up well with cleaning. The swivel feature is great though.

Very nice car seat

Cybex is one of the best carseats that exceeds Saftey standards. I spent way too much of my pregnancy researching. Got the cloud q and the dj khaleed epriam and loveeeee the ensemble! Now that my son is older and i might have another infant, I figured this sirona s that can get in both ways is perfect. Cloud q is really great for preemie, sirona s is a bit larger but still can accompany itty bitty babies!

Great, sturdy and handy car seat, our son loves it. The only downside is that you are not able to rotate it in the front facing mode.

At first it’s a bit hard to install, but its a very good quality car seat, we use it since my baby turned one, so it’s almost one year since we have this car seat and I’m very happy with the purchase. It’s comfortable, nice, easy to wash/clean and it’s a big plus that you can rotate the car seat.

I wanted to love this car seat, but after having it for 3 months my 14 month old figured out how to unbuckle the chest clip. It’s nice that I get an alert, but I wish they made it childproof. He’s not old enough to get the concept not to do that which means we have to either pull over every 5 minutes while driving, have someone ride in the back with him, or use the button up shirt trick. The car seat is very user friendly and very nice quality, it’s a shame we’ll probably have to get a whole new car seat for him.

I’ve had this seat for almost two years now- I bought it once my little one outgrew her infant seat. I love this car seat and if I had to get a new one today, I’d just buy the same thing. We stopped using the censor safe awhile ago- we work from home so we don’t have a lot of opportunities to accidentally leave her in the car and she talks now so it would be pretty difficult. It did have a fair amount of warnings that were unnecessary- car is cold or hot- but nothing too crazy and it was worth the peace of mind while she was small. The swivel is just amazing. We don’t accidentally bump her head, there’s no extra stress on our backs getting her in (I’m almost 40, so I’ve got a fair amount of wear and tear on my back already). I did get it stuck in the wrong direction once, but was able to google my way out of it. The seat itself is very heavy and large. It almost doesn’t fit in our Mercedes GLB- the passenger seat has to be pretty far upright to get it to click in, but I’m short so I can keep the seat up. I had to move it on a few occasions and it felt like a lot of work. The first couple of times I installed it really sucked. I’d never installed a car seat before and just felt like it was really difficult to get it to feel secure. Now, im an old pro. I liked this seat enough that when I wanted to get a car seat for my moms car (and not move this behemoth again), I got another one from cybex.

The car seat is good and we like it. Has one of the most difficult car seat install. I would recommend this seat if you are planning to install your seat once and leave it in your vehicle.

We bought this seat when my toddler transitioned from her infant seat. We loved the swivel motion, which helped a lot when putting her in/out of the car. This car seat feels secure with the extra leg, that is the primary reason why I choose this particular seat. After 2 years of use, we had a problem with the latch used to turn the seat, it was no longer clicking so we couldn't use the seat anymore. We contacted cybex and since the seat was blocked facing the door of the car, there was nothing we could do but they said that they will send us another car seat free of charge. We had to dismantle our car seat literally because it wouldn't come off, but nonetheless, we found that the spring that was connecting the latch was not attached anymore! I opted for a different seat without the swivel motion, as my child was older and I don't really want to have this problem in the future. It was an inconvenience since the seat was blocked in the car, therefore we couldn't use our car seat for some days until the new car seat shipped. Overall a good car seat, safe, secure, easy to use

The CYBEX Sirona S is a phenomenal car seat, albeit decently challenging to install. When looking for a easy to operate car seat for smaller family cars, this seat received excellent reviews, and we now know why: it is very well constructed with advanced safety features we have not seen in any other car seats, including active monitoring systems linked to your car's OBD-II diagnostics port. We appreciate the ability to transition our child from backwards facing to forward facing at the push of a button / turn of the seat. Additionally, the set it and forget it nature of this seat makes it a no-brainer for active families that are sick of spending unnecessary time carrying, latching, and belting their kids into traditional car seats. Once you are able to get the seat installed (I would suggest having a partner help you with a few steps in the installation process, an extra set of hands is very helpful), this seat rocks. Absolutely worth the cost!

Love rotating the seat!

My baby unclips himself from the harness within two minutes. It’s very easy to do. Also, it’s impossible to install on your own. I had to pay for someone else to do it. Pretty disappointed overall considering it’s one of the most expensive car seats on the market.

My girl loves to stay in her car seat, easy to install and like the quality.

The concept of this car seat is great, but it is heavy and difficult to install if you don’t have at least a minivan or a lot of space. My daughter is 3 and weighs less than 40 lbs, she has cubby little legs and I find that I’m pinching her every time I clip in the seatbelt if I’m not careful. There is not enough length to sit the buckle comfortably on her crotch. I was hoping to use this for a long time, but sadly we’ve outgrown it and I’ll need to spend another 400 dollars on another car seat before she can safely switch to booster.

We love this carseat! We were transitioning out of our Doona, and looking for something that would make life easier with our 23lb 6mth old. This works great, she's comfortable and has plenty of room to grow! We also get lots of compliments on how clever and cool it is! Thanks!

I have twins so I purchased two Cybex siona S car seats. I transferred the boys from their infant seats to these at about 11 months. They are so much more comfortable now. I love the ability to flip them forward facing with such ease. And the fact that they don’t need to be reinstalled once the boys are ready to be forward facing. Also, they rank very high in safety among other car seats. Highly recommend!

We love this seat. it has a few small issues, like the swivel can some times be difficult, and its very heavy. other than that its worked great!

This seat is huge and would not be appropriate for a lot of cars without having to put the front seat all the way forward. We could not get a secure install so ended up having to have a professional install but I still don’t feel it is as secure as our Nuna Rava seat. The sensorsafe component is also terrible. You will get dozens of alerts for temperature etc. while you are in the car. If you are in the car in the summer and you know it’s hot you don’t need a critical alert notification every 90 seconds while the car is on. This could be life saving if it only alerted when the car is off (ie in the case a child was left in the car), but the excessive alerts just causes you to turn off the alerts thus making it useless. It does seem comfortable and the rotation is convenient but for the money I wish I got another Rava instead.

We really love this car seat, it is really the best one on a market. We tried multiple brands and this one is superior. We have no complaints at all and like all the futures especially ability to rotate it 360*.

This is a good concept for a car seat and very convenient for loading and unloading a kid, but there were a few things that could have been better. The cup holder broke off the first day. I wish the cup holder would’ve been more sturdy and not a clip on. The load leg takes up a ton of room and we had a very hard time getting it secure and tight. My little one would get super fussy if he was in it for longer than 30 mins or so and I don’t know if that’s just him being antsy or if the car seat wasn’t comfortable enough. We had to replace due to something getting in the car and chewing on the straps. Cybex does not sell replacement straps.

I enjoy this new and improved car seat that is easy for a grab and go. Able to put baby in and out of car seat very easily with the swivel design. I recommend this car seat for first time moms or multiple children.

So convenient! Makes life so much easier. My child feels safe and secure

Great product but very difficult installation.

I’m all about find ways to make daily tasks easier and this car seat does that. This car seat wasn’t available when my son was younger and I always bumped his head trying to load him in. With the Sirona S I love being able to face the seat towards me for loading and unloading. I’m sure my daughter loves it too because I’m not accidentally hitting her head on the car. We started using the Sirona S at 14 months when she outgrew her infant seat and plan to continue use for as long as we can. I highly recommend this seat.

My baby is very happy in this car seat. However it was a nightmare for my husband and I to install. We still don’t know how to make larger the seat belt

We've owned a ton of car seats and this is by far our favorite! The swivel is life-changing and all of the parts feel smooth to maneuver.

I love how this feels extremely soft. I do wish I would’ve gotten the black instead of the grey because grey shoes EVERYTHING. But one thing I didn’t like about this car seat is the installation. My husband things it’s simple but every single time I install, I don’t feel comfortable with the finish. I love how it swivels for easy access. It does take up quiet a bit of room. But overall, it’s study, safe, made high quality.

We love this so much!

I had a hard time at first with the install, but turns out I wasn’t checking the seat correctly. I consulted the website Car Seats for the Littles and they have a page about how to check the seat only at the beltpath. Turns out I had installed the seat correctly the first 3 times. My child is not quite grown out of her infant seat but we decided to purchase a new one as she is getting heavy to carry in the old one. I love the rotation feature and how it has a coupe positions for her rear facing. She seems so comfortable in it. Cybex has stated the feather doesn’t have to be used in the forward facing position as long as the load leg is in use. This makes the rotation feature available. I will probably still use the tether at that time as my hope is she will be able to climb in the seat herself. Got it for the best price here on Albee so I’m pleased overall. The photo shows her rotated but she does not ride sideways. The seat must be locked into place before the car moves.

I purchased this car seat during Black Friday and got the best price and service. The car seat came so quickly. I couldn’t be happier with the product and would definitely buy it again from Albees

I gave it 3 star considering all factors. Pros: Seat turns and make putting baby in a lot easier when it's rear facing. Cons: Difficult to install. Seat and front of the base still move after a very tight installation. Makes me wonder about it's safety. Fabric is so so and on the cheap side. Operation is a bit awkward.

I really wanted to love this carseat, and I actually did really like it for the first few months when we had a large SUV and could use the leg to help support the carseat. It was still incredibly difficult to install correctly and get it to stay stable, but we figured it out and loved it for about 3 months. We had to get a new car (still an SUV, just a little smaller) and we have tried every possible method and even watched many videos on installation and just can't get the seat to stay tight. I'm very concerned for my baby's safety, as the carseat wiggles around (way more than the 1 inch that is "safe") within a day of re-installing. While I love the 360 feature of the carseat, the hassle I have to go through to constantly re-install it and the fear I have for my child's safety is simply not worth it. I've been trying to get in touch with Cybex for over a month about the issues I'm having and I'm getting ignored. For the price paid for this carseat, I'm really unhappy with the results and the service I (haven't) received.

This car seat was one of the highly reviewed and recommended car seat in my community. This one was always on the top 3 convertible car seat and the main pros was that it saves your back. And it really does! Other fixed car seats require you to tilt your baby to the side, squeeze him/her in to put the belt in, fight them in a weird position, all happening towards the side. But this one, since you can swivel the chair to make your baby face you, everything is so much easier. You can either stand at the outside or you can face your baby when you are sitting next to them inside the car. One downside is that the supporting leg isn't that sturdy. I did install it properly and it has the green sign on but I just always have a feeling that it might have issues and may cause the car seat to either shake or slide (it won't but just feels like) to the side. One major downside - you don't have ease in your mind. Could be my personal issue but that single supporting leg just doesn't seem sturdy as other ones.

This carseat was so difficult to install, especially in my tiny BMW I3, but I needed a swiveling carseat to make the car work. Took me roughly an hour with the help of my husband to get it to not wobble around. And there is this silly stupid plastic compartment door that keeps POPPING off. But otherwise, its lovely. The quality is obviously there. My babe is really happy in it and he absolutely hated his infant car seat, Nuna Pipa. It's easy to get him in and out. The swivel feature is very cool. I generally like the thing, just can't believe the struggle to get it properly installed. I have yet to use it facing forward. Only rear facing.

I love this car seat first for safety and secondly for it is convertible

I procrastinated installing it because I was intimidated, but it wasn’t as hard as I feared. I used the YouTube instructions. I have not been successful hooking up to the safety sensor, but working on it. Will call help line if I am not successful today. Seat, with all the padding, looks really comfy, though wish it inclined a bit more. I have a tiny 2 month old(within weight limits) who is a bit more upright than I like. I have a bad back, so love that it revolves towards me so I don’t have to twist to get little guy in. Expect it to be even better as he gets older and bigger! -Overall, it’s expensive, but hopefully worth the $ in the long run.

I initially got this car seat for my rear-facing son but often used it for my forward facing daughter as well. The swivel and no re-thread hardness made it very convenient to switch between forward and rear facing. I will say, however, it was very difficult to install securely. I quickly realized I had been spoiled with my Britax Clicktight car seat. No matter how hard I tried I was never able to get the installation quite as secure as my clicktight. I now have this car seat in my husbands car so he can take one of the kids without having to totally re-install a carseat to be forward or rear facing. One major plus to this carseat is that its machine washable and does appear to be very comfortable for my little ones. Biggest con is the installation. If you are going to be taking the car seat in and out, I would recommend a different one.

I love this car seat! Definitely watch a youtube video for the installation, but once you figure out how to use that lever thing, it's pretty easy. We had the nuna before with the same stability leg thing, so having that on the Cybex is comforting. The swivel makes taking baby in and out of the seat SO much easier! No more head bumping against the end of the car. It's also great when we're waiting in a parking lot or something to turn baby towards you to play for a bit. There's a gap between the top and bottom cushion which is a little annoying because I know there's a pile of cheerios gathered in there but that's probably true of any car seat. The senor is super annoying so we disconnected but the temperature gauge on the seatbelt is great. I'm sure the Evenflo is also wonderful but I don't regret paying what we paid for the Cybex.

I have always used Britax or Chicco seats with my 3 children and have always been very happy with them. I decided to get the Cybex seat because with my bigger SUV and also being on the short side it was difficult to put my 1 year old in the car. This seat has been a life saver, I no longer struggle to get him in the seat. I love the swivel function and my son is happy and comfortable. I am so glad I purchased this seat.

Love this car seat. It's so easy to put my little one in it and get his properly fastened! I swivel him around and off we go. I will say it's very hard to install and I had to call one of their professionals for them to help me install it. The seat is very comfortable for my big boy!

The install is annoying & difficult. Customer support from Cybex is a week long wait. Watched many YouTube install videos & finally figured it out. There’s a lot of info to know if you installed it properly. Example, only use the base to see if it’s done well. Don’t sway the top, it’s supposed to sway. Really easy to turn, amazing recline! Head never goes forward when toddler falls asleep.

This was not the eaiest car seat to install and it had some wobble at first, so you will need to put in the time to get it in snugly. That said the wivvel feature is usful for so many reasons. It's easy to load your little one into the seat and roating it when they are not with you allows the front seat to be used!

We LOVE this car seat! It may be one of the most expensive car seats on the market but it is worth every penny. It’s so convenient to get the baby in and out without straining our backs. I can tell it’s a comfortable ride for the baby too. He stopped screaming at red lights once we installed it. I was nervous about the price before we got it but 10/10 I would recommend this after using it.

I've had this car seat for about a year now and have absolutely loved it!! The swivel is great for daycare drop-off and pick-up, I love the SensorSafe feature (we thankfully haven't needed it, but it gives me peace of mind), and the load leg is a big win in my book as well! It's super easy to take the cover off to clean and put back together. Overall, a great car seat that I would definitely recommend.

Thus car seat feels so luxurious and hugs my baby so perfectly. I love the swivel and I helps to not break my back.
