Reliably safe and easy travel
Say goodbye to hassle and back strain at the start of your journey. The Sirona S2 i-Size car seat features a genius one-hand 360° rotation mechanism for a fast entry and exit. It’s your new secret weapon for easy and comfortable boarding. The Sirona S2 i-Size lets your child sit rear-facing to improve safety in the event of a head-on collision. If you make the switch to forward-facing, Energy Reduction Technology makes the journey safer. The headrest and harness system are designed to reduce the energy of impact forces, so whichever travelling direction you choose you can be rest assured your child is protected.

Installation with isofix: Pay attention to the i-Size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-Size child seats and will therefore not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.
- 360˚rotation mechanism
- The 360° rotation mechanism takes the back strain out of getting your child onboard. It’s a breeze to swivel the seat to the door side and get your child in and out. Switching between rear and forward-facing travel also couldn’t be easier.
- 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 S2 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 S2 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.
- Energy Reduction Technology
- Energy Reduction Technology improves safety performance during front-facing travel. Impact forces are transmitted directly into the car seat via the harness system, where they are partially dissipated by energy-absorbing materials. This reduces the forces acting on the child’s sensitive neck by approximately 20%.
