Nuna PIPA Aire RX Infant Car Seat + RELX Base is the lightest full-featured infant car seat in the PIPA lineup — weighing just 6.2 lbs without canopy and inserts — with Tailor Tech™ memory foam, GREENGUARD Gold certification, and the PIPA RELX base included.
The PIPA Aire RX uses aerospace aluminum accents, Aeroflex™ foam for lightweight energy absorption, and Merino wool + TENCEL™ inserts for sustainably sourced comfort. The included RELX base features a True Lock™ rigid LATCH 50% stronger than a standard belt latch, an integrated anti-rebound panel, and a multi-position steel stability leg.
