Onyx

Onyx provides your growing child (76 – 150 cm) with the very best protection whenever you’re on the road. With integrated G-CELL panels and a 5-point safety harness, they’re fully protected in the event of forward as well as side collisions. And thanks to its five comfortable recline positions, your little one has the cosiest seat in the car every time you hit the road.

Safety

Onyx is designed for safe journeys together. It meets the highest and latest i-Size safety standards and keeps your child protected throughout childhood. Its integrated G-CELL panels provide the very best protection in the event of side collisions, while the 5-point safety harness offers the most secure fit as they grow.

Ease of use

Comfort

Your child can make use of five recline positions that keep them comfortable whenever using Onyx in harness mode. Whether they’re taking a nap on a long journey watching the world go by outside the window, Onyx ensures they remain cosy and comfortable in their seat.

Great car seat

Verified purchaser

Lovely car seat brought as needed to be able to fit three car seats across the back row and it’s narrow enough and doesn’t spill over into the middle seat. ( Ford Smax) Very easy to install and move when needed, my toddler seams very comfortable and very happy to sleep in it too.
