Cybex SIRONA M2 i-Size

  • UN R129/02 i-Size
  • HEIGHT 45 cm – 105 cm
  • WEIGHT max. 18 kg
  • AGE From birth up to approx. 4 years
    The CYBEX Sirona M2 i-Size complies with the new European requirements and regulations for car seats UN R129. This “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.
    Highest safety and comfort until your child reaches 105cm in height

    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.
    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

    Rear-facing car seat
    Significantly reduces the risk of injury in case of a head-on collision. The Sirona M2 i-Size allows you to transport children rear-facing from birth up to a height of 105 cm (approx. 4 years)*.

    Alternative – Forward Facing
    The Sirona M2 i-Size features a click-in system that allows for easy interchange between forward and rear-facing position. Depending on your preference, the Sirona M2 i-Size can also be used as a forward-facing car seat for children who are 16 months and 76 cm and above (up to 105 cm).

    Integrated Linear Side-impact Protection
    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 (L.S.P. System) increases the level of safety in case of a side-impact collision. The L.S.P. system can be folded out and reduces the force of a side-impact collision in combination with the head and shoulder protectors.

    One-hand recline function
    Easily adjusts to the perfect position (rearward facing: 5 positions; forward facing: 3 positions).

    12-position height adjustable headrest
    Protection that grows with your child. 12-position height adjustable headrest with integrated harness guides that grow with your child.

    One-Click Installation with ISOFIX
    A one-click installation with ISOFIX* both in rear- and forward-facing position allows for simple installation and guarantees increased safety.
    Sirona M2 i-Size is secured using the car’s ISOFIX system* and requires no further fastening. An installation indicator also helps to prevent a possible misuse.

    M-Line Modular System
    This modular system has all you need. With the infant car seat Aton M and your Sirona M2 i-Size you can click two seat onto one base. This ensures a safe rear-facing journey for your child – from birth up tp approx. 4 years.

    Energy-absorbing shell
    Absorbs the forces of an impact and protectively covers the baby.

    NB – Isofix Base Not Included. Base M available.
