The Nuna NEXT™ System Explained

The Nuna NEXT System is designed to give parents maximum flexibility during the first four years of their child’s life. Instead of buying multiple bases, the NEXT System allows several compatible car seats to work with one rotating ISOFIX base.

This modular approach means you can upgrade your car seat as your child grows while keeping the same secure base installed in your car.
