The CYBEX Sirona S is the ONLY Convertible car seat to feature a 360 rotatable seat with load leg stability, linear side impact protection and SensorSafe technology.

The CYBEX Sirona S is the first Convertible Car Seat in North America to feature an innovative 360° rotatable seat with a load leg, making switching between rear-facing and forward-facing positions quick and easy. The Sirona S load leg stabilizes the seat and can significantly reduce crash forces. These features, combined with an EasyLock™ bar for quick, simple and secure installation, offer advanced safety protection for children — and greater peace of mind for parents.

With SensorSafe™ technology, you'll gain instant insight into your child's well-being—right to the SensorSafe app on your phone. Built into the chest clip of CYBEX car seats, SensorSafe provides alerts when unsafe situations arise including if a child unbuckles themselves; if the back seat has become too warm or too cold, if a child has been seated for too long, and if the driver accidentally leaves the child behind.

  •  Innovative, one-hand 360° rotatable seat allows parents to easily get their child in and out 
  • Load leg stabilizes the car seat and can reduce rotation in certain crashes by up to 30%

  • Linear Side-impact Protection absorbs up to 25% more impact in a collision* 
  • Anti-rebound design reduces car seat rebound movement

  • Dishwasher safe cup holder can be positioned on either side of seat 
  • 12-position, height-adjustable headrest with no-rethread harness

Cybex - Sirona S 360 Rotating Convertible Car Seat

Stacey K. (Burlington, Ontario)
The perfect carseat

Easy to set up and to maneuver daily. I feel so much safer with my daughter in this car seat.

Nadia H. (Dollard-des-Ormeaux, Quebec)
Easy to use but difficult installation

We like the car seat however it was difficult to install. The 360 feature is really what made us buy it and we really enjoy that. The car seat seems very comfortable for our son and we also love that there are different levels to put him in once we click the car seat. I just find that the clips are a bit hard to close.

Game changer

Amazing car seat! Took me a little while to secure it into my truck. The base is solid but i still find it to be a bit “wobbly” . Maybe it’s just because it swivels ? The swivel is a huge game changer - super easy to function with one hand / getting them in and out of the car.
Do watch you’re babies feet when you swivel with them in it; they can get caught . Love this seat and recommend for sure !

Paloma S. (Stouffville, Ontario)
Excellent purchase and car seat

The car seat it is everything we expected, the swivel feature is the best feature, it makes easy to put our child in and out of the car seat. I love the clip safe buckle and tells you if the child is in the car if you leave the car, if temperature is safe, if clips gets unclipped. The blue indigo color is very nice. 1 cup holder. Easy to install. The speed of the delivery (standard delivery) was excellent, we got our car seat in 2 business days, we didn’t expect it that soon and more because other baby stores had this car seat with back orders. Easy and fast check out. First time buying from this store and the experience was extremely positive. We will definitely buy from here next time.
