Maxi Cosi Onyx i-Size Car Seat

£229.99

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

Each day is made easier with Onyx. Its 5-point safety harness can be used up to 4 years (105 cm), and after that, you can store the harness away in the seat to convert the car seat to booster mode. Your little one can then be buckled up quickly and easily using the car’s seat belt.

Age range

Onyx is the multi-age car seat that’s designed to grow with your child. It can be used from 15 months all the way up to 12 years old (76 – 150 cm). It adapts to their changing needs as they grow thanks to its height adjustable headrest and high back booster design.

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.
