Sirona S Convertible Car Seat
The Cybex Sirona S is the only convertible car seat that protects your child and your back. The car seat rotates 360 degrees, allowing you to rotate the seat toward your car door while helping your child in and out
The NEW CYBEX Sirona S is the first Convertible Car Seat in the U.S. to feature an innovative 360° rotatable seat with load leg technology, 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
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.
