The Sirona S i-Size car seat from Cybex means no more uncomfortable lifting when getting baby in and out of the car. Since it's the safest way to travel, this car seat offers comfortable rear-facing travel for children up to 105 cm (or approximately 4 years). The Driving Direction Control (DDC) prevents forward-facing use before they're at least 16 months old and 76 cm tall. Sirona S i-Size also provides increased safety in the forward-facing position thanks to the Energy Reduction Technology. Read more below to learn how this car seat provides optimal safety as well as comfort for baby.


  • 360° ROTATION MECHANISM: The innovative 360° rotating mechanism of the Sirona S i-Size makes switching between rearward and forward-facing position easy. In addition, it provides a comfortable entry and exit position with less strain on parents' backs.
  • REAR-FACING CAR SEAT: The Sirona S i-Size allows you to transport children rear-facing from birth up to a height of 105 cm (up to 18 kg, approx. 4 years). Depending on your preference, the Sirona S i-Size can also be used as a forward-facing car seat for children (starting from min. 76 cm and 16 months up to 105 cm).
  • DRIVING DIRECTION CONTROL: The Driving Direction Control (DDC) prevents misuse of the forward-facing position of the car seat. It ensures the forward-facing position is not used before the child is at least 16 months old and 76 cm tall.
  • ENERGY REDUCTION TECHNOLOGY: The Energy Reduction Technology of the Sirona S i-Size offers increased safety for your child in the forward-facing position in the event of a head-on collision. It reduces the forces on the neck of a child during a front crash by approximately 20%, compared to other existing harness systems.
  • INTEGRATED LINEAR SIDE-IMPACT PROTECTION: The integrated L.S.P. System of the Sirona S i-Size offers increased safety in the event of a side-impact collision. It reduces the force of a side impact in combination with the energy absorbing shell by approximately 25%.
  • ONE-CLICK INSTALLATION WITH ISOFIX: Sirona S 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.
