Cybex Sirona Gi i-Size Car Seat - Moon Black Plus

£299.95

360° comfort and safety

The latest car seat in our successful Sirona line is the most comfortable yet: the Sirona Gi i-Size, best in class* at the 05.24 ADAC / Stiftung Warentest.

Rear-facing for safer travel, this car seat also features integrated Linear Side-impact Protection for defense from all directions. Upgrade your child’s comfort with 360° rotation for smooth on and off-boarding.

All-round air ventilation keeps the ride cool – choose the Plus version for additional mesh and even more breathability.

Five recline positions provide tailored comfort in either direction, for tiny newborns and fully-grown four-year-olds alike. 360° of comfort and safety for their first four years: the Sirona Gi i-Size.

 

Up to 50% higher safety levels*

Rear-facing is one of the safest ways to travel. In the critical first moments of a front impact, the child's body is pushed against the padded car seat shell, minimising movement and reducing the force acting on the child's neck.

Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for comfortable rear-facing travel until your child weighs 20 kg. (*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2,022 ADAC frontal crash test criteria.)

 

Quick and easy onboarding

A stress-free start to your journey. Just swivel the car seat to face the car door and get your child onboard. You avoid back strain, while your child stays comfortable in any recline position.

 

Optimal breathability

Comfort in any season. All-round air ventilation lets air flow through channels in the car seat, carrying away heat and helping avoid a sweaty ride for your little one. The Plus version also includes mesh fabric that increases breathability up to six times compared to regular fabrics.
