Am I allowed to use an i-Size homologated car seat?

Yes. The i-Size legislation has officially been adopted by the United Nations Economic Commission for Europe (UNECE), and approved in all countries that are a member of the European Union.

Some countries may have to adopt these rules in national laws, but until then Maxi-Cosi actively supports you to use i-Size car seats.

Can I use an i-Size homologated car seat in my ISOFIX car?

Yes. i-Size is an evolution of the current ISOFIX car seats, and is often referred to as super ISOFIX. i-Size car seats have always been intended to be backwards compatible with ISOFIX cars. The legislation is also officially adopted in order to allow this installation.
