Sirona Q i-Size Rear-Facing Car Seat

The new CYBEX Sirona Q i-Size complies with the new European requirements and regulations for car seats ECE R-129. This new "i-Size regulation" states that children aged 15 months and under must travel in a rear-facing infant car seat, which is seen as the safest mode of transport by many experts, including consumer and health organisation such as the ADAC and the German independent consumer testing organisation Stiftung Warentest.

Safely rear-facing up to 18kg

When using the CYBEX Sirona Q i-Size, the child can be transported in a rear-facing position from 45 cm until they reach 105 cm in height (approx. 4 years). The new, intelligent design means that even taller kids have plenty of leg room to sit comfortably. But it doesn't take up too much space either – the Sirona Q can be easily installed in smaller cars. Additional features such as the one-hand reclining function provide extra convenience and make everyday use easier.
