Product Details

The Cybex Sirona has long been a favourite of parents with its ability to be used in both rear and forward facing positions, with the ability to go rear-facing all the way up to four years. One thing many a parent has said is "But I wish it was i-Size compliant!" and so Cybex listened and created the new Sirona M2 i-Size!

  • i-Size tested to highest safety standards
  • Extended rear facing for additional safety
  • Multiple recline positions for little one's comfort
  • Height adjustable headrest grows with your child
  • Install safely in seconds with ISOFIX connectors

All about me

The Sirona M2 is a little bit different from its predecessor; the swivel and impact cushion are gone - but all the safety and comfort features are still there and improved to ensure it meets the stricter R129 (i-Size) standard! A new feature is the integrated Linear Side-impact Protection system to offer a shock absorber to help absorb energy from a side impact faster.

The removal of the swivel function allows the Sirona M2 to be more compact (the original was rather bulky!) which gives it great compatibility with cars. The seat now has a click-in system which allows for an easy change between rear-facing and the optional forward facing position.

Keeping a great deal of adaptability, the Sirona M2 has a 12-position height-adjustable headrest to grow with your child, and the harness grows too so no complicated rethreading. The harness can also be held open with the magnetic clips to make getting your little one in and out easier.

For your child's comfort and an ideal sitting and lying position, the seat has 5 recline positions in rear-facing mode or 3 in forward-facing mode. It's easy to operate one-handed.

The Sirona M2 is now part of the new Cybex M-Line Modular System where the included Base M ISOFIX base can first be used with their Aton M Infant Carrier and when it's time for the next stage seat, you can continue to use the same base with the Sirona M2. Please note, the Sirona M2 is only truly i-Size compliant when used with the ISOFIX base.
