## Description

The CYBEX Sirona S is the first convertible car seat in the U.S. to feature an innovative 360° rotatable seat with a load leg, making switching between rear-facing and forward-facing positions quick and easy. This rotatable seat, along with magnetic buckle holders, makes it easy to get your child in and out. Designed for safety, the Sirona S features a steel-reinforced frame and anti-rebound design that reduces car seat rebound movement. Linear side-impact protection system absorbs up to 25% more impact in a collision when compared to the same car seat without L.S.P. extended. A one-time belt installation secures both forward and rear-facing positions. Our EasyLock™ Bar works with your vehicle belt for easy and secure installation, while the dual-level indicators ensure the car seat is at the proper angle. Adjust your Sirona S as your child grows, with a 12-position headrest with no-rethread harness. SensorSafe™ technology in the chest clip syncs automatically with your mobile app and provides alerts of unsafe situations, including if a child unbuckles themselves; if the back seat is too warm or cold, if a child has been seated for too long, or if the driver accidentally leaves the child behind.

## Questions & Answers

**Q: Does it alert you if you forget to take the baby out of the car after the car is turned off?**
A: I do not own this carseat but a friend does. I am someone who got alerted that my friends child was left in car, and where car was. Because of covid child was being cared for by relative who normally did not care for the child. Child is fine care of alert. Thank you to whoever came up with this

**Q: I installed this with the seatbelt and latch and it’s wobbly. i feel like i can tip it over. what did i do wrong?**
A: This seat only allows for install using one method - Seat Belt, or Latch, not both at the same time.  I would reccomend installing using seat belt - oncle you click it, pull the extra slack in the seat belt down where the buckle is, and then route the shoulder belt portion the rest of the way before you lock off - most times, the installer leaves too much slack in the lower belt and that is why it moves for any car seat.

**Q: Why is this car seat not stable? it wobbles side by side .**
A: Most have better luck installing this with the seat belt, over the latch system. The user manual also states, "In some vehicles in the most 
reclined position, it may be necessary 
to place a rolled towel or small blanket 
beneath (not behind) the Child Restraint 
near the seat back to provide enough 
recline so that the Recline Ball is in the 
BLUE ZONE for REAR-FACING use.
NOTE: Only items approved by CYBEX 
are allowed under Base."

**Q: Will this fit in a Chevy trailblazer?**
A: Some child restraints do not fit all vehicles or all seating positions. There are so many different combinations of vehicle makes, models, child restraint configurations, seat belt designs and seat cushion designs.  Dimensions of the seat  H 25.5” x W 20” x D 25.3”.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great car seat, tricky to install
*by O***R on December 31, 2020*

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!

### ⭐⭐⭐⭐⭐ Great car seat!
*by S***H on December 16, 2024*

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.

### ⭐ Design disaster! OMG this seat is impossible to install safely
*by M***S on March 6, 2024*

Spent hours on this, finally put it side by side with Uppababy Mesa and City Turn to see why it just couldn't be installed securely via seat belt or anchor belt. We loved the secure feeling of this seat - your baby is truly in a protected cocoon, surround by heavy thick materials, with nice fabric and really solid heavy duty belts and buckles. Everything feels great. BUT the seat is let down by its base, which, even when the seat is back in locked position, allows so much slack between the top rotating section and the base that you get a click each time you brake or accelerate. Then, this slack is accompanied by having to push your baby and chair up to vertical in order to rotate the seat, so you're not even gaining rotation at any swivel angle for that slack. Last, and this is the worst part, the design of the base, in order to accommodate that big cocoon for your baby, requires the belt path for both seat belt and anchor belt to travel very close to parallel with the vertical surface of your vehicle seat. This means it's impossible to get enough back/forth pull, or tension in the direction perpendicular to the vehicle seat surface, to secure the seat. The belt path is basically too flat against the surface, unlike the City Turn or Uppababy Mesa, so you can never tighten the belt enough to secure the seat to your car. Or if you do, like I really tried, you start deforming/damaging your car seat belt or the Sirona's anchor belt. What a mess. Maybe they fixed this in new European version, but we seem to only have the Sirona S here in the US for now. Easy fix is to put a spacer of 3 or 4 inches between car seat and your vehicle seat, to add perpendicular belt path, but then for sure the Sirona will bump up against the front vehicle seats in most cars. So close!! The City Turn took 5 min to install tight. The Sirona S never made it. Google it - everyone has problem installing it tightly. Even if the base is set in concrete, there's still so much slack between base and seat, sigh.
