- Rear-facing car seat
- When positioned rear-facing, the seat significantly reduces the risk of injury in case of a head-on collision. The Sirona Zi 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 Zi 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). However, CYBEX recommends that children travel rear-facing in the Sirona for as long as possible.

- Integrated Side-impact Protection
- 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 approx. 25%.
