Product overview

M-LINE MODULAR SYSTEM - The Sirona M2 fulfills the latest safety standards and completes the 'family-system' together with the Base M and the Aton M i-Size infant seat offering one base for two car seats (Base & Aton M available separately).

The new CYBEX Sirona M2 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 organisations such as Which?, the ADAC and the German independent consumer testing organisation Stiftung Warentest.

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.

The integrated linear side-impact protectors (L.S.P. System) fold out on the side facing the door, reducing the force of a side-impact collision at a very early stage of impact. Whether rear or forward-facing, the CYBEX Sirona M2 i-Size’s integrated Linear Side-impact Protection system increases the level of safety in case of a side-impact collision. 

The Sirona M2 is super comfy and adjusts to your growing child with 12-position height adjustable headrest with integrated harness guides that grow with your child. One-hand recline function so you can easily adjusts to the perfect position (rearward facing: 5 positions; forward facing: 3 positions).

  • Rearward facing up to 105 cm, approx. 4 years
  • Alternatively forward facing from 16 months and 76 cm
  • Integrated L.S.P. System
  • One-hand recline function
  • Height adjustable headrest
  • Click-in system to change seat position
  • Easy Installation with Base M (available separately)

PLEASE NOTE: This car seat can only be installed into a vehicle with the Base M. The car seat base is available on it's own or as part of a package.
