Product Details

When using the CYBEX Sirona M2 i-Size, the child can be transported in a rear-facing position from birth 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 M2 i-Size can be easily installed in smaller cars. Additional features such as the one-hand reclining function provide extra convenience and make everyday use easier.
