Comfortable travel in the safest position.

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.

Reduces impact forces in the forward-facing position.

Energy Reduction Technology improves safety performance during front-facing travel.

This reduces the forces acting on the child´s sensitive neck by approximately 20%.
