Cybex Sirona S2 i-Size Car Seat - Lava Grey

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.

360˚rotation mechanism

The 360° rotation mechanism takes the back strain out of getting your child onboard. It is 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 could not 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%

Integrated L.S.P. System

The integrated L.S.P. System increases safety in the event of a side-impact collision. In combination with the energyabsorbing shell, it can reduce the force of a side impact.

One-hand recline function

The one-hand recline function makes a peaceful drive only a moment away. Quickly adjust the seat and your child can take a relaxing nap on the go. With five settings available in both riding directions, it is easy to find the perfect sleeping position.

Height-adjustable headrest

The height-adjustable headrest has 12 settings for a customised fit. As your child grows it is simple to adapt the seat to keep pace.
