Product description

Bébé Confort’s FamilyFix One i-Size works perfectly with the Rock, Pearl Smart i-Size, or Pearl One i-Size, providing you with an easy-to-use Click & Go installation. It fits both baby and toddler car seats, enabling long-time use.


More and more cars in Europe have ISOFIX connectors, so your car will most likely have them as well. Our Bébé Confort FamilyFix One i-Size attaches to your car’s ISOFIX anchorage points for a safe fit. Our user manual tells you exactly how to connect the ISOFIX base to your car, step bystep.

Once installed, you can leave the FamilyFix One i-Size in the car. This way, every time you need to get in and out of the car, the baby car seat is fitted onto the base with a simple secure "click”. Visual indicators on the base notify you when your Bébé Confort car seat is correctly installed, and you are ready to "go”.

Keep using our FamilyFix One i-Size, even when your little one outgrows their baby car seat and is ready for a toddler car seat, such as the Pearl Smart i-Size or Pearl One i-Size.

The FamilyFix One i-Size can be installed in combination with the Rock baby car seat, and the Pearl Smart i-Size or Pearl One i-Size toddler car seats.


At Bébé Confort we have carried over 50 million babies home from the hospital. External crash test centres, such as the German automobile organisation ADAC (Allgemeiner Deutscher Automobil-Club), regularly test our Bébé Confort car seats and bases on dynamic safety and ease of use.

When ADAC tested our Bébé Confort FamilyFix One i-Size and Rock, they rated them as above-average for safety and ease of use. After having undergone extensive testing for frontal and side impact protection, our car seat and base received excellent scores on safety. Using the ISOFIX base is recommended for your baby car seat’s swift and easy installation in your car.

Besides its extensive safety test, the FamilyFix One i-Size also scores high on its ease of use. The ISOFIX base offers a Click & Go installation, making it easier to install the car seat, and reducing the risk of doing it wrong.

ISOFIX installation for Rock, Pearl Smart i-Size and Pearl One i-Size

Owning a baby car seat requires that you correctly install it on a daily basis. Because we want to help you as a parent, we make things that work for real families. Our Bébé Confort FamilyFix One i-Size has been constructed to make things easier for you. Thanks to its Click & Go installation, a simple "click” will do the job to guarantee a safe connection, every single time you need to get in and out of the car.

Bébé Confort FamilyFix One i-Size fits our Rock baby car seat and Pearl Smart i-Size or Pearl One i-Size toddler car seats. Additionally, the FamilyFix One i-Size allows you to install the toddler car seat in a rear-facing position. Experts recommend that your little one travel in a rear-facing position for up to 4 years, because this offers enhanced head and neck protection. For this same reason we, at Bébé Confort, recommend that your toddler travel in this position for as long as your little one fits the toddler seat. Besides, the ability to use the ISOFIX base for up to 4 years offers you great value.
