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.

Base G
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.
