CYBEX Sirona S with SensorSafe, Convertible Car Seat, 360° Rotating Seat, Rear-Facing or Forward-Facing Car Seat, Easy Installation, SensorSafe Chest Clip, Instant Safety Alerts, Premium Black

We love this car seat. It is sturdy, safe, comfortable for my toddler, and easy to adjust. My only real critique is how difficult it is to install. My husband and I spent an hour to install it initially and moving it between cars is a total pain. But otherwise, we are overall pleased with our purchase.

I bought this seat as I am becoming a foster parent for children 0-2. I wanted a convertible seat that would accommodate any child in this age range. I loved that this seat swiveled. It's currently the only convertible swivel seat in the USA.Back story: I survived a deadly car accident in 2012. I was driving an Audi, so since German engineering saved my life before, I had high hopes for this German car seat. (Made in China though) 🙄I now drive a 2013 VW Jetta. When the car seat arrived today, later than expected due to the storms in New England, I was SO excited to put in the car.After two hours of trying to get this seat to not wobble, I called it a day. I'm returning it tomorrow morning. Which is a huge pain given that the refund doesn't come for 2-3 days AFTER the seller receives it. So I'll have to wait another two weeks to order a different seat.I have worked as a preschool teacher for all of my adult life and have installed hundreds of car seats over the years. I have NEVER seen a car seat wobble like this. Even the $40 Cosco car seat from Walmart didn't wiggle like this.For $500 I expected the dream convertible car seat but I am highly disappointed. There are multiple points on this seat that are flawed.1. The latch system belts are not sewn well. It wouldn't surprise me to see these become a reason for recall.2. The latch system doesn't fit well in the two alcoves meant to contain them once latched. They don't allow for the belt to be tightened enough because they're restricted to the space in the alcove.3. The belt system which is noted as the "preferred" method is useless. I'm sure the shape of my VW's seats play a role but minimally. The blue plastic pieces that are to hold the belt....I would say are upside down. There's nothing to prevent the seat belt from being pulled back up in the direction of the seat.4. Because of these little alcoves for the latch - you need to weave the belt through the alcoves but its such an odd space that again even with the car's seat belt, it won't tighten enough.5. Cybex thought to add a compartment on the back of the seat for the user manual but didn't think to add a handle anywhere on the seat to be able to carry it. It's HEAVY! And awkward!6. The fabric is so smooth (yay) but is a type that is going to grasp on to every hair or fiber that comes it way. I could tell immediately that it would be a bitch to maintain.7. The base itself has a much smaller width than the top of the seat. - I would think that due to physics this is why the thing wobbles. If the base was wider and more comprehensive espically by the edge of the VW's seat (where there's more natural give) then the Cybex wouldn't wobble.On a side note, I had emailed the company previously about any type of discount/program/grants available to try to lessen the cost. They emailed back to say they don't offer anything like that.Additionally, I couldn't find a crash test video anywhere for the seat.They sell for 270 Euro which converts to 195.5 Dollars.This Cybex seat is not worth $500.

Love the rotating feature! I don’t hate loading and unloading my kid anymore. It was pretty difficult to install we used the the preferred seat belt method. When installed improperly you will be able to notice because it is all wobbly. I was like nope we did something wrong lol! But once we set it up properly it was way better and it was not wobbly! My only issue is that the lock rotation indicator doesn’t work and we called Cybex. They informed us that they had not heard of such an issue but as long as seat is locked when we aren’t grabbing the handle to rotate it that it is good. Hope that makes sense. It’s a tiny bit annoying but we checked when he was reclined if it rotated and it didn’t and that means it is locked. I’ll definitely keep an eye on that.

I really struggled with installing this and had to get professionals to help me. They explained the way the bench in my car worked it wasn't a good fit for having it in the middle, though i'm sure this varies by vehicle. If it's important to you to have your car seat in the middle seat and you don't have an SUV, i'd go with something else. We now have it installed on the side and it's been wonderful. The swivel has been a big relief for my back, and I don't feel I had to make sacrifices safety wise for it like I did with other swivel seats I researched. Our daughter appears very comfortable, the straps move smoothly and hold her firmly in place, and the sensor-safe works extremely well (though I needed the pros to show me where to plug that in too!). Unfortunately kiddo vomited in it ,but we found it very easy to clean! Everything came off the base and went back on easily and washed right out the first try. When the seat swivels, the leg pops up which can be unsettling but once the seat is locked in place (forward or rear facing) it isn't going anywhere. I'm grateful for all of the visual reminders indicating the seat is installed properly because we moved our front seat and it knocked the support leg off kilter. I noticed right away because of the color coding indicators at the top. Very glad we chose this car seat!

I absolutely love this carseat! I did a lot of research about the best convertible carseat regarding safety (crash testing), comfort, etc. I was stuck between this and the nuna rava which are the best rated car seats for comfort and scored highest on crash tests. I really wanted the 360 swivel as my son is a big boy so I opted for this one and I'm glad I did!!! Nuna has the Revv with 360 swivel, but it scored horribly on crash tests and only went up to 40 lbs so again this was definitely the better option. I've read a few people say it's very hard to install, but my husband got it installed within 5 minutes after watching the video that is on the QR code with the carseat. It also has a blue tooth sensor that is connected onto your phone which alerts you when your baby is buckled, temperature too hot or too low, etc. It really is so cool and the swivel is very easy. I'm really happy w/ this purchase and my son seems very comfortable in it. Only negative thing I would say is this is a very big carseat, so if you have a small sedan it might not be the most ideal; I drive a ford explorer so it fits good
