Nuna pipa™ rx + pipa relx base

Stylish car seat that securely installs with or without the PIPA RELX™ base for greater flexibility.

It’s a brand new world for them. Your world has forever changed. Enjoy every magical moment with PIPA rx, a car seat bringing such comfort to your baby, you’ll feel it too.

It starts with a full-coverage canopy with pull-out Sky drape™ attaching silently with magnets and keeping them shaded.

Equal in versatility and safety, PIPA rx is fashioned solely from materials that are free of fire retardant additives. Give them—and yourself—a good start
