The Nuna PIPA RELX base is the foundation of Nuna’s infant car seat system—designed to make daily installs faster, safer, and more consistent. While often overlooked, the base is one of the most important parts of your car seat setup.

Positioned as a premium safety + convenience upgrade, the RELX base stands out with features like a stability leg, anti-rebound panel, and 5-second installation system. For parents using Nuna PIPA series infant car seats, this base transforms everyday use—especially for families managing multiple vehicles or frequent transitions.
