The CYBEX Sirona S Convertible car seat features a 360° rotatable seat with load leg stability, linear side impact protection and SensorSafe technology.
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.
Smart-tech harness chest clip with SensorSafe™ technology provides alerts when unsafe situations arise including if a child unbuckles themselves while the vehicle is in motion; 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 after the vehicle has been switched off. These alerts are provided through an installed vehicle receiver and a user-friendly smartphone SensorSafe App.
