Cybex Sirona S Rotating Convertible Car Seat with SensorSafe 2.1, Children Newborn to Four Years, Easy Child Load, Infant Baby Toddler Preschooler, Indigo Blue
Why we love it
360 Rotatable Seat
EasyLock Bar for Secure Install
SensorSafe Alerts for Safety
Main highlights- Superior Protection: Linear side-impact protection (L.S.P.) absorbs up to 25% more impact in a collision compared to the same car seat without L.S.P. extended while the anti-rebound design reduces car seat rebound movement in the event of a crash.
- SensorSafe: Built into the chest clip, SensorSafe provides app alerts 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, or if the driver accidentally leaves the child behind.
- EasyLock Bar: Reduces the force needed up to 4x for simple and secure car seat installation. Dual-level indicators ensure that your car seat is at the correct recline angle while our load leg can reduce rotation in certain crashes by up to 30%.
- Convertible Car Seat: The first car seat in the U.S to feature an innovative 360° rotatable seat, the Sirona S makes it quick and easy to switch between rear-facing and forward-facing positions and get your child in and out of the car.
- Adjustable Headrest: Make sure your car seat is always a perfect fit with 12 different headrest positions. The Sirona S harness adjusts without re-threading, making it easier to adjust the height of the shoulder straps as your child grows.
