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.
