Really great carseat

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!

Convenient but difficult install

By Gailan

Verified Buyer

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.

Pros

Rotation

Cons

Size, difficult install, excessive sensorsafe alerts

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*.

Pros

Safe

Soft material
Baby loves it from the first use
Able to swirl 360*

Cons

A little bulky

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.

Pros

Turning capability to load or unload

Cons

Hard to get installed securely
Only one cup holder that is a bit flimsy

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.

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.

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.

Pros

Rotation feature
Good padding
Long rear facing option
Takes a high weight limit once forward facing
Super easy to remove pads for washing

Cons

Tether use prevents rotation forward facing
Cup holder is awkward

Just OK

By X G.

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.

Pros

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

Cons

Difficult to install.

Great in theory, but poor execution and incredibly difficult to install

By Kenzie

from Alexandria, Virginia

on December 15, 2021

Verified Buyer

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.

Pros

360 makes it easy to get my baby in and out

Cons

Won't stay tight
Very difficult to install
Horrible customer service

Swivel saves your back!

By June

from California

on November 24, 2021

Verified Buyer

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.

Pros

Swivels - Easy to seat your baby in and out
Steel frame
High-tech sensor

Best Uses

Moms with lower back pain

Cons

Supporting leg doesn't seem to be as sturdy as it seems

Cool but Difficut

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.

Swivel is awesome, Quality, Comfort, Convenient

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.

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.

Pros

Safety
Looks comfortable
Technology (safety sensor )

Cons

Having trouble connecting to technology
Heavy - it?s not coming out of the car until it?s outgrown!
Expensive

Convenient, cozy and complicated

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.

Pros

swivel, comfortable, wipes cleans

Cons

installation, big and bulky

By No R.

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

By Brooke2294

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!

I have always used Britax or Chicco seats with my 3 children and have always been very happy with them.

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!

Pros

Features and look. Rotation is great for different use cases.

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.

By Jason

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.

Swivel is awesome, safety features, ease of in and out

No stepping on the baseboards to strap in

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.

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.

By Cathy

from Las Vegas NV

on February 17, 2021

Verified Buyer

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.
