SIRONA S I-SIZE REAR-FACING CAR SEAT

360° convenience for you – optimised safety for your child

No more awkward lifting and back pain when helping your child in and out of the car seat. The innovative one-hand 360° rotating mechanism provides a comfortable entry and exit position, ensuring less strain on parents' backs.

  • 360° rotation with easy entry position
  • Rearward facing up to 105 cm, approx. 4 years
  • Driving Direction Control (DDC)
  • Energy Reduction Technology (ER-Tech) in forward-facing position (from 16 months and 76 cm)
  • Integrated L.S.P. System
  • Height-adjustable headrest
  • Newborn inlay included

Because it's the safest way for your little one to travel, the Sirona S i-Size provides comfortable rear-facing travel for children up to 105 cm, approx. 4 years. The Driving Direction Control (DDC) prevents forward-facing use before the child is at least 16 months old and 76 cm tall. Sirona S i-Size also offers increased safety for your child in the forward-facing position thanks to the Energy Reduction Technology. It is activated as the forces reach their full impact in a head-on collision: The headrest slides down, progressively limiting the neck’s exposure to the impact forces, and subsequently locks into position.
