The CYBEX Sirona S is the only Convertible Car Seat in the U.S. to feature an innovative 360° rotatable seat with load leg stability, linear side impact protection, and SensorSafe™ technology. The rotating feature makes it super easy to get your child in and out, and also convenient for switching between rear-facing and forward-facing positions. The load leg helps decrease rotation of the car seat while the side impact protection system absorbs impact forces in certain crashes. Built into the chest clip, SensorSafe provides app alerts when potential unsafe situations arise. These features offer advanced safety protection for children and greater peace of mind for parents.
