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.

Under no circumstances should a rearward-facing car seat be used on a passenger seat where there is an active airbag.

Correct fitting of all car seats and boosters is of paramount importance in making them the most effective in the event of an accident. Not all car seats fit all cars and it is important to check for fitting suitability on all cars you intend to fit the seat to, as well as re-checking if you change your car.

Always read the instruction booklet that comes with your car seat to achieve a safe and correct fitting, retaining the guide for future reference. We recommend fitting your car seat in advance of first using it.

We recommend that babies shouldn't be left in car seats (infant carriers) for prolonged periods.

Please make sure that you check the car seat you choose is suitable for your car before ordering. This can be done in store with a Partner or on the car seat manufacturer's website.

All the car seats in our range are designed to give your child the best possible protection and meet the criteria set out in the R129 (iSize) safety regulation. A baby must travel in the safer rear-facing position up to the minimum recommended age of 15 months. Some R129 car seats can be used rear-facing until a child is 105cm tall, which is around 4 years old.

Side impact testing is assessed as part of the regulation to improve the protection of the child's head and neck. R129 also makes use of the most high-tech crash test dummies which not only has improved sensor technology to test for greater sensitivity, but it also features more sensors on fragile areas of the body. iSize is an enhancement of R129 that makes it easier to confirm your car seat's compatibility with any iSize approved vehicle - reducing the risk of installing your car seat incorrectly. While all i-Size car seats meet the R129 testing standards, not every R129 car seat is an iSize compatible seat.

R129 (iSize) car seats are classified by height only. The below table is a rough guide as to how the car seats can relate to a child's age based on the average child's height. In some instances, we may still need to check the weight of the child within the height band due to the maximum mass load permitted on a vehicle's ISOFIX points.

Note: This is a rough guide only. Please always refer to the individual car seat's guidance for more specific details. Some car seats will be approved for use across two or more height bands. This just means that these seats have the ability to adapt as your child grows, meaning they can use them for longer.
