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.

I recently purchased this car seat, and so far we are all loving it! I definitely wanted the swivel feature, and it has been so worth it for me. My daughter didn’t care for her last seat as time went on, but she’s been happily sitting in the Sirona S. I highly recommend!

This car seat is HUGE and heavy But I must say the swivel helps a lot since I just broke my elbow and use 1 hand a lot And the sensor safe works well with the app and the chest buckle even glows blue for a second after the baby is buckled in My son is 11 months and fits nicely with room to grow Not sure how comfortable when he’s 2 with longer legs

We have been using the Cybex Sirona S for 5 months now and it is wonderful! The swivel feature makes getting out LO in and out of our vehicles so easy! The Sensorsafe alert reassures us that we will be less likely to forget about the LO in the car - especially when tired, full-time working, parents of a toddler are sleepy and have not yet had enough coffee or rest!

Love love love this car seat!! It’s so easy to get my son in and out now with the swivel feature. Also the install was pretty easy and it feels very secure with the load leg. Love all of the safety features and know we will use this car seat for years to come. My only con was that it’s so expensive. But I am so happy I found it on Albee for a discount!! Love using this site for big purchases.

This is by far the best convertible car seat. My husband and I have back problems and this really makes parking our baby in and out so much easier. Shipping was excellent. I am pleased with this buy.

My son totally Outgrew the Doona and I was totally lost what to get for a car seat. This one is amazing, the material is so soft and comfortable, he looks so happy in it with plenty of room to grow, but extremely safe. He also likes the options of sitting up or reclining. It was not difficult to install once we actually figured it out and besides it being heavy wouldn’t be the end of the world if we had to move it from car to car.

Let me first say that I love this car seat, but we are having to send it back over a major safety concern. Our 15 month old continues to push the chest latch release while driving. The spring on the single button release takes no effort to release and we can't take that risk. Thank goodness for the OBII sensor for constantly notifying us that this was happening. This is only the only complaint about this seat, but it's a huge one for me and my family as I'm not willing to take that risk.

This carseat is worth every penny. It's a task just getting out the door with a little one so making it quicker and easier to put them in their car seat is such a time and tear saver! It's not super easy to move from car to car so wouldn't recommend if you have to move it around often.

We love it

The product is great, baby loves the seat and gets so excited every time she goes in it. The downside is, I have a 2013 Dodge Durango and I had the worst issues getting it installed correctly and took forever!

makes my life ten times easier getting my daughter in and out - just a little bulky.

This car seat is very well made, and feels modern and cool. The swivel feature is the main reason to buy this car seat. Because otherwise I would just buy something less expensive. Installing it was a little hard, but now that’s it’s in its nice to know it sits in rear facing it forward facing so I don’t have to install it again.

I actually don’t agree with the other reviews saying it was hard to install, I thought it was very easy to install actually. I love the swivel affect, during my pregnancy I ended up having a really bad back. I drive a Tesla model Y and not having to bend over to put my son in the car is amazing. The only downfall is when you have the car seat facing the front, you have to use the tether. This does not allow your car seat to swivel, which defeats the purpose of the swivel affect. I’m sure you can use the car seat without the tether,But I like my car seat to be very tight and sturdy. The leg was a little janky, every now and then it would turn red. So if that is some thing that concerns you, you might want to get another car seat.

I love this car seat so much I purchased a matching one for our second car.

I am so happy with this purchase. I don’t know how anyone lives without the rotating seat. My son doesn’t always enjoy being strapped in, so the rotating seat makes it much easier to get him in safely and gently.

My sister in law recommended this car seat and I’m so happy we got it. It’s so convenient with the 360 mode and the safety features are unbelievable. Everyone asks about it every time they see us taking baby out the car. Highly recommend!

The swivel feature is super handy and the seat is a wonderful and comfortable delight for my daughter. SensorSafe is awesome! Upgrading from the wonderful Cybex Aton Q. Wife and I have been Albee Baby and Cybex fans since 2015. Cybex has proven its quality for our family with long lasting products that stand the test of time for car seats. Can’t say enough! Her twin brothers are on the 2nd row with her in the 2020 Volvo XC90. This Sirona S works best for us set up behind the front passenger. Twin A sits behind the driver in his Evenflo Maestro Sport. Twin B sits in the middle seat aka Volvo’s integrated booster with Volvo’s excessively over priced booster seat overlay to make it function more like a high back booster than a booster alone. I’m 5’8 and my wife is 5’3 and we’re comfortable at the moment not using the third row for the twin boys with the high back boosters. One of the boys is happy and the other is happily tolerating it (the one in Maestro Sport). We have a Maxi Cosi RodiFix ordered and on the way. Hoping it’s narrowness might be even better than Maestro Sport and the seat more comfortable than the Maestro Sport and easier for child to buckle himself independently. As a fan of German engineering, I seriously considered a Cybex Solution booster. In my quest for 3-across comfort on a second row, I’m trying RodiFix instead. Love the Albee shopping process and prices. Thanks Albee Baby!!

My daughter hated going into her infant carseat, and when I saw this seat could swivel I figured it would be a lot easier to get her in/ out of her new seat. The installation was very difficult, because the isofix system prongs are a little longer than the isofix on our Uppababy. Once, we did get it installed the seat was nicely secured and didn't move. My daughter seems to love her new seat! The app can get a little annoying, and if your phone is connected to Bluetooth it'll stream notifications through the speakers. The carseat rotates seamlessly while my daughter is in it, and offers her (32 inches tall) a lot of leg room in rear facing. So far we're very happy with our purchase and considering buying another one for my husband's car.

It works great and easy to install. Only downside was you can’t take out the car seat from the base. Also it’s heavy. But otherwise I love all the features.

I recommend this car seat to everyone I know!! I would pay the price over and over again. I was so excited to find out there was finally a swivel car seat approved for the US market!!! Makes loading my toddler in such a breeze! Can’t imagine how difficult it would be without the swivel option.

I absolutely love this car seat. Easy to use. Only reason I did not give it 5 stars is installation is very confusing. My husband looked at several utube videos to install correctly. Read instructions. Now that it’s done it is perfect!

Fabric quality = soft and plush Recline positions = so many to keep kiddo comfy Swivel = must have! Style = classy and polished Load leg.... = may not work in ALL cars or with LARGE dogs that share the space Installation = a little tricky Overall, I really like this car seat and will be buying another for baby #2.

This carseat is a great plush quality. It swivels very easy and has many great options.

We bought this for our road trip up to NC & baby loved it!!!! Our son is 8 months and weighs about 24lbs. This car seat was perfect for him. It seems spacious and comfortable. Worth every penny.

We got these car seats for our twin grandsons at 16 months, because their baby sister is coming. My dil loves them! It makes it so much easier to get the twins in and out. The seat is so soft and comfortable. They never complain when getting in. The installation took us longer than anticipated but is pretty straight forward. The load leg needs to be checked every time they are loaded in. They haven’t used the senor safe yet.

This car seat is a godsend. It was a little difficult to instal, but once it’s in, it’s the best car seat you could have ever purchased!

So I was going back and forth on this car seat and the nuns exec since we already had a nuna pipa but hunny, this car seat comes with everything I need as I first time mom and more... my baby loves it and sleeps or stays quiet and enjoy his car ride. . Love it

I bought this for my best friend’s son. It is pricey but I think it is worth it since it will last long time. The best feature is that it spins when you take your baby off the carseat! The Manhattan grey color is beautiful!

Not going to lie it is heavy, the videos make it easy to install. The rotating feature is the best part of this seat. No more hitting heads or getting frustrated with my daughter not sitting in it correctly and trying to buckle it.

This is a great car seat. It is quite large, and barely fits in my wife's Volvo XC90. Definitely check the product dimensions before purchasing. We assumed we would have no issues fitting this in a SUV, but it is a tight fit.

Love it!! I wish I bought it sooner. I bought it for my 1 year old baby girl. Fit really good in a Lexus Gx 460 with captain chairs. Sturdy, comfortable and beautiful! It feels really good to have it because it has a lot of features that makes it safe. Came in time.

The rotation capability of this seat can't be overstated. Not only does it make it so much easier to get baby in and out of the car without bumping her head, it also means you can swivel it when not in use and gain that much needed leg space for the passenger in front. Plus Cybex gives you a video appointment with a car seat professional to ensure you installed it correctly, which is the most important factor when it comes to car seat safety! I also really wanted the peace of mind from the sensorsafe.

Obviously the swivel feature is fantastic. Other features including fabric, straps/adjustment, load leg, anti-rebound, recline are all very good too. Difficult installation is the one negative. The length of the vehicle belt or lower anchor strap through the belt path is VERY short. Taller buckles may not allow for a snug enough fit. Vehicle belt is the recommended installation method, and lower anchor strap may only be used until the child weighs 35 pounds. Anchor guides might help with a more secure lower anchor strap install, but they are not included. Given that Cybex and Evenflo are by the same company, I would love to see Evenflo's Easy Click system adapted to this seat.

This seat makes it easy to get our child in and out since the seat can turn toward you. The load leg makes it safer than any other convertible car seat I have found. The only problem is as for rear facing the child grows you have to make sure you have their feet up to get it locked into position but that is a minor issue.

Love this seat. Easy to install and the swivel is LIFE CHANGING! Not a huge clunky car seat either.

Since out little guy is just about to grow out of his infant car seat, we have been looking around for the next step. Initially, we had our eye on the Nuna Rava, but then saw this guy. We love it and so does our little one. It feels much safer than its competitors with the load leg and rebound bar. It also fits nicely and securely in both our sedans. Because the seat swivels, getting out active little guy into the car is a breeze. The only annoyance is the sensor safe app. It literally went off anytime we put our LO in the car due to the temperature outside. Since the app is somewhat archaic, you can't tell it what you want to be alerted for. I see how this can be a great safety feature, but it needs to be improved.

My order came in three days! So quick and easy. Lovely car seat.

We had the Sirona M car seat but decided to upgrade due to swivel function of the Sirona S! We love it! Install was not as bad as anticipated, but watching the instruction installation video is a MUST!! I didnt even bother trying to follow written instructions. But we love the car seat so far!!

Love the swivel feature! Makes taking a baby in/out of rear facing so much easier! The car seat also looks super comfy. My little one has no complaints! The sensorsafe is a okay feature. I can take it or leave it. I can see where it can be helpful to a sleep deprived parent. Only downside is that it can only pair to 1 cellphone.

I wanted to love this car seat so much. I love all the safety features like the loading leg, SIP, and the sensor safe technology. However after installation the car seat was very loose. I tried several times and even sent a video to Cybex and they said it was normal, but I was not comfortable with the movement. Also, after removing the tape from the SIP one of the sides would not close back. Very disappointing. I will be returning it for the Nuna Rava which we have already in my husbands car and love it. Hopefully I won’t have an issue returning it and exchanging for the Nuna Rava.

We got this to use instead of a Nuna Rava and I LOVE it. We have a forward facing toddler and I haven’t quite figured out how to tether it while still being able to rotate it to get her in and out but other than than that we are in love! We plan to buy another for my husbands car. Our little one is immobile and has special needs and isn’t able to help at all at climbing into her seat so this will save our backs!!

Can’t say enough good things about this seat!

With a toddler that doesn't not like to be strapped in, having the rotating feature was a selling point for me. Less of a struggle each time to try to put him in the car seat. WIN! The car seat itself is of great quality and I like the Sensorsafe feature for added piece of mind. Just a FYI- we have a BMW X3 and the seat belt harnessing worked in our car with no issues as well as in the X5.

This seat seems super awesome and was our number one choice for convertible car seat. I would give it 5 stars, but after trying to install it, it became clear the seat belt anchoring system would not work with our vehicle, the Volkswagen Atlas. This was confirmed through technical support with Cybex, so we had to return it. I would recommend it, but make sure it will work with the seat belts in your vehicle first.

Toddler loves it. We are road tripping family and comfort and safely is always a must! This car seat is both and much more!!

I bought this solely for the rotating feature and was very pleasantly surprised that, aside from that awesome feature, it’s still my favorite car seat (out of about 8 or 9) that I’ve ever used. The rotating feature works as easily as the videos show. The seat is super padded and very comfortable. The fabric is very high quality and definitely the nicest I’ve ever seen on a car seat. The harness loosens and tightens very smoothly which has been a huge issue on our past convertible seats. I haven’t set up the Sensorsafe yet so I’m not going to speak on it, but given the very high quality of the seat in general, I’m assuming it works great. The install was a bit tricky, but mostly due to the fact that I hadn’t read the directions carefully enough - I’d watched the video. I do recommend carefully reading the full installation instructions AND watching the videos. I had somehow missed that you close the belt tensioner with the EasyLock. Not sure how I missed that, but don’t make that mistake because it’s MUCH easier if you do it the correct way. When I move the car seat at the belt path, the install is rock solid. However, that was a little tricky to achieve because the more slack you pull out of the seat belt, the harder it is to lock the belt tensioner into place. If you don’t pull enough slack out, the car seat isn’t tight enough even after closing the tensioner. So you have to find the balance. Even with the seat being totally unmovable at the belt path, it’s still slightly loose feeling towards the load leg end. I’ve never used a seat with a load leg before, but since the load leg is locked into place correctly (there’s two indicators - one to show that you’ve folded the load leg out fully and the other to ensure adequate contact with the floor of your vehicle - the indicators are red if the leg isn’t in place correctly and are green if it is) and the seat doesn’t move at the belt path, I’m assuming the little bit of give there is normal. Also, the seat doesn’t take up much room from front to back when rear-facing. It’s about the same footprint as our infant seat (Chicco Keyfit 30) - maybe even a tad less - and that’s with it fully reclined. My 10 month old doesn’t hate the car, but she had been fussy lately when putting her in our other convertible seat. She seems to like this seat much better and doesn’t fuss in it. Oh and lastly, the harness shoulder pads are fantastic. They’re super soft and snap instead of Velcro. It seems like a small thing, but we’ve had several seats with pads that we’ve ended up just taking off if they were removable. These are by far the softest and most useful. I’m very happy with this purchase and am fighting the urge to buy a second one for my husband’s vehicle. 😬
