The Cybex Sirona has been developed to safely extend the time that children can travel in a rearward-facing position. Due to its innovative design, children can be transported rearward-facing up to approximately four years of age. Once the child has outgrown this position, the car seat can be used in a forward-facing manner – starting at 9 kg up to approximately 18 kg. Thanks to a one-click ISOFIX connection and a clever rotation mechanism, it can be turned from rearward- to forward- facing mode without having to reinstall the seat. At the same time, this function offers an easy entry and exit position.
