Functions

Quick and easy to get your child onboard

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.

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.

Preset side-protection for error-free installation

Advanced Linear Side-impact Protection is ready to use from the start, with no extra installation required. In combination with the energy-absorbing shell, it can reduce the force of a side impact by approximately 25%.

Reduces impact forces in the forward-facing position

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%.

Quick change to a sleeping position

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.

Grows with your child up to 4 years old

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.

Easier to get your child in and out of the seat

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!

Straightforward installation and anchorage in your vehicle

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.

Diverts impact forces away from your child

The energy-absorbing shell is designed to flex with an impact and channel dangerous forces away from your baby.
