Safety comes first with the FamilyFix S, the dedicated ISOFIX car seat base for the S-Family. Compliant with the highest i-Size safety standards, it ensures your child's lasting protection. FamilyFix S offers the recommended and safest rearward-facing position up to 4 years old.

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.

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.

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.
