The CYBEX Sirona S convertible car seat brings parents some peace of mind. Not only does it have an ultra-convenient 360-degree rotatable seat, but it's the first of its kind to also offer load leg stability, linear side-impact protection and Sensor Safe technology. The innovative height-adjustable load leg element is integrated into the base of the seat and extends down to the vehicle floor, which can significantly reduce crash forces. The Bluetooth-enabled chest clip provides real-time, in-app alerts when potentially unsafe situations arise: including if a child unbuckles the chest clip, if the back seat becomes too warm or too cold, and if the driver unintentionally leaves the child behind. These features—along with the EasyLock bar for quick and simple installation—offer a safe and secure ride for your little one.
