  • Driving Direction Control (DDC)
  • Energy Reduction Technology (ER-Tech)

360° convenience for you – optimised safety for your child

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.
