Installing your car seat is never a hassle with our Maxi-Cosi Pearl One i-Size! First, install the FamilyFix One i-Size base in your car using the ISOFIX connectors. Then snap the Pearl One i-Size car seat onto the base with a simple "click”. The base will notify you each time when your baby is secured and you are ready to "go”!Check the user manual or read our checklist for correct ISOFIX installation.



At Maxi-Cosi we have carried over 50 million babies home from the hospital. For us, your child’s safety is Maxi-Cosi’s top priority. External crash test centres, such as the German automobile organisation ADAC (Allgemeneir Deutscher Automobil-Club), tested our Pearl One i-Size on dynamic safety and ease of use, and rated it as good.


In addition, the Maxi-Cosi Pearl One i-Size car seat holds the Swedish PLUS-test certificate, a safety test which rates car seats based on the performance of their head and neck protection. Rest assured that in a PLUS-tested car seat, your child is well-protected in the event of a frontal collision. Last but not least, our Pearl One i-Size complies with the latest European i-Size safety standard for improved safety. It offers better head, neck and body protection while enabling up to 105 cm (approx. 4 years) of rear-facing travel with the base unit, which is considered the safest travelling position for children. The FamilyFix One i-Size will give you peace of mind by providing visual and audible confirmation when the seat is securely attached.
