Product Description
CYBEX Sirona Gi i-Size Car Seat
The CYBEX Sirona Gi i-Size Car Seat combines extended rear-facing travel, 360° rotation and advanced side-impact protection with everyday comfort for your growing child. Suitable from approximately 3 months to 4 years, or from birth when used with the compatible newborn inlay, it allows children to travel rear-facing up to 20 kg for enhanced protection during the early years.
Its smooth 360° rotation allows the seat to turn towards the car door in any recline position, making it easier to get your child in and out. Integrated Linear Side-impact Protection works alongside the energy-absorbing shell, while multiple recline positions, all-round air ventilation and straightforward ISOFIX installation help make every journey safer, cooler and more comfortable.
Extended Rear-Facing
Allows your child to travel comfortably rear-facing up to a maximum weight of 20 kg.
360° Rotation
Turn the seat towards the car door for easier boarding, even while the seat is reclined.
Linear Side Protection
Integrated L.S.P. works with the energy-absorbing shell to reduce forces in a side impact.
