    360° Comfort & Safety

    Say hello to rear-facing travel with the ADAC awarded CYBEX Sirona G i-Size car seat, with up to 50% higher safety levels¹ for your child. Innovative 360° rotation makes on and off-boarding so much simpler for parents as the child is placed in a much more manageable position. Once on-board they'll be cool and comfortable whatever the weather, with an all-round ventilation system with special mesh fabric increasing breathability by a factor of six². A cleverly integrated Linear Side-Impact Protection System gives streamlined, reinforced protection in the event of a side collision. As part of the Modular G family, the base you had for the Cloud G i-Size fits perfectly to this seat: continuous safety for the first four years.

    Rear-facing travel is obligatory until your child is 15 months old. The Sirona G i-Size provides up to 50% higher safety levels in its rear-facing position¹. In the event of a front impact, the child's body is pushed against the padded car seat shell, minimizing movement and reducing the forces on the neck. A safe position you can count on until your child is 4 years old.

    An innovative 360° rotation mechanism makes it so easy to get your child in just the right position to get them in or out of the car, even when the seat is reclined. Swivel the seat with one hand: much quicker and so much better for your back.

    As part of the Modular G Family, the Cloud G i-Size and Sirona G i-Size both fit onto the Base G. Once your child has outgrown the infant car seat, the Sirona G i-Size installs on the base with just one click. Thanks to ISOFIX installation, it's a user-friendly, safe foundation for the first four years (Base G available separately).

    Base G  

    Required


    The Sirona G i-Size clicks on and off the Base G. This is installed using a load leg and ISOFIX. The Base G ensures safety and stability, and it can also be used with the Cloud G i-Size infant car seat. Look for the i-Size logo in your vehicle to check compatibility. If there is no i-Size logo but your car has ISOFIX, please check our Car Compatibility tool.
