    The innovative one-hand 360° rotating mechanism provides a comfortable entry and exit position, ensuring less strain on parents' backs.

    The Sirona S2 i-Size allows your child to sit rear-facing up until 18kg/105cm, to improve safety in the event of a head-on collision. If you make the switch to forward-facing, Energy Reduction Technology will help to improve the safety for forward facing, however, rear facing is always safest! The headrest and harness system are designed to reduce the energy of impact forces.


    A rear-facing car seat improves your child’s safety in the event of a head-on crash. In this position front impact forces are distributed across the car seat shell. It is mandatory for children to travel rear-facing until they are over 15 months old and 76 cm tall. However, CYBEX recommends that children travel rear-facing in the Sirona for as long as possible.

    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%.

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

    ISOFIX is a reliable way to install the car seat in your vehicle. Set-up is simple with fast one-click attachment and a load leg to anchor the seat in the vehicle. Easy-to-check indicators confirm when the seat is installed and ready to go. 

    It can only be installed in cars with isofix and no underfloor storage compartment.

    **Please note that Sirona S2 itself has not been tested by ADAC yet. However, the Sirona SX2 has been tested by ADAC. The Sirona SX2 and SIrona S2 have the same ECE certificate number.   


    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 different settings available in both riding directions, it’s easy to find the perfect sleeping position.

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

    The belt holders are a genius feature that give you a helping hand with getting your child on board. Hook the harness straps out of the way – the simple solution to tangled-up limbs!
