About this Car Seat Base

This base is designed with safety in mind. The one-click installation makes the Base One very easy to use since it works with the ISOFIX system and has individually rotatable ISOFIX connectors, making it even easier again! Installation indicators provide confirmation you have correctly installed the base and seat, giving extra peace of mind. What’s more, all the seats are very easy to use, they click-in in less than a second on the Base One. All you have to do is enjoy your family trip!
