Seems very comfy
December 28, 2021
I had a hard time at first with the install, but turns out I wasnít 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 doesnít 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 Iím pleased overall. The photo shows her rotated but she does not ride sideways. The seat must be locked into place before the car moves.
  • Rotation feature
  • Good padding
  • Long rear facing option
  • Takes a high weight limit once forward facing
  • Super easy to remove pads for washing
  • Tether use prevents rotation forward facing
  • Cup holder is awkward
  • Installation is not as easy as the other rotating seat sold here
  • Sensor safe doesn?t connect correctly

I gave it 3 star considering all factors.

Seat turns and make putting baby in a lot easier when it's rear facing.

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.

Great in theory, but poor execution and incredibly difficult to install
December 15, 2021
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.

Swivel saves your back!
November 24, 2021
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.

  • Steel frame

Cool but Difficut
October 19, 2021
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.

Very pleased with my Sirona S car seat. It was easy to install (watched videos and read manual before installing so I was able to do it quickly without frustration. Also scheduled a call with their car seat tech to make sure it was installed correctly and it was! ;0) My daughter falls asleep in it, my back appreciates I don't have to lean in to put her in the seat. The magnetic holders for the clips are super handy. I would recommend this car seat to anyone looking at a rotating base seat. I was looking at the new even flow and this one definitely is better quality.

August 19, 2021
I procrastinated installing it because I was intimidated, but it wasnít 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 donít have to twist to get little guy in. Expect it to be even better as he gets older and bigger! -Overall, itís expensive, but hopefully worth the $ in the long run.

Convenient, cozy and complicated
August 11, 2021
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.

Love the swivel
August 2, 2021
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.

Saved my daughters life
July 31, 2021
I don't ever write reviews but this is extremely important to all the parents in the world. 2 days ago my daughter and I got hit by someone running a red light at 50mph (15 mph over the speed limit). I had her buckled in the Cybex Sirona S and right where my daughter site is where we got hit. She doesn't have one cut or bruise on her body. I'm fact she has been cleared by both paramedics and the ER that she is perfect okay. She is 11 months old and of course rear facing. This car seat saved my daughter's life. I was told this by 8 cops, 2 doctors, 4 nurses, 2 paramedics, 4 emts, and 6 firefighters. I will never use another car seat again in my life, Cybex will forever be the brand we purchase, it is well worth every penny. If your trying to justify spending the money look at the picture of my car, right where the triangle window is is where my daughter was.... She didn't even get a scratch. I have whip lash, a concussion, my neck and back got strained and bruised. Thank you Cybex for taking the time to make these car seats. I will be getting another one soon!

Great car seat!
July 30, 2021
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.

Instal is difficult but worth it
July 3, 2021
The install is annoying & difficult. Customer support from Cybex is a week long wait. Watched many YouTube install videos & finally figured it out. Thereís a lot of info to know if you installed it properly. Example, only use the base to see if itís done well. Donít sway the top, itís 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!

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.

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!

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 wouldnít be the end of the world if we had to move it from car to car.

I want to love this, but It's got a safety flaw
April 16, 2021
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.

April 14, 2021
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.

Great features but has some minor cons
March 1, 2021
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.

Rear facing is amazing. Front facing not so much.
February 17, 2021
I actually donít 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. Iím 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.

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. Canít 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 Volvoís integrated booster with Volvoís excessively over priced booster seat overlay to make it function more like a high back booster than a booster alone.

Iím 5í8 and my wife is 5í3 and weíre 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 itís 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, Iím trying RodiFix instead.

Love the Albee shopping process and prices.

Thanks Albee Baby!!
  • Easy installation. Safe & comfortable. Promotional prices.
  • It?s large from front to back when considering impact on front seat passengers. I?m glad my wife and I aren?t any taller. The the back seat where this eat is installed is pushed back and reclined back as far as the second row will allow of the 2020 XC90.
  • Still worth it to have it, but I?m glad I don?t have this Sirona S installed behind the seat of this 5?8 driver.
Best UsesFor parents or the grandparents because it?s super convenient as long as your car has the space. My family prefers European cars and this is a European engineered seat, but I wish somehow European cars and SUV?s were a little more forgiving. My recent experience is with the 2020 Volvo XC90.

Difficult Install
January 31, 2021
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.
