360° Comfort and 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. The 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 will 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.

Up to 50% higher safety levels
Up to 50% higher safety levels
Rear-facing travel is compulsory 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, minimising 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 faster and so much better for your back.

The Base G ensures safety and stability, and it can also be used with the Cloud G i-Size baby 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.
