A multiposition base is equipped with an easy-to-use true lock™ installation system to help secure your nuna PIPA car seat in just five seconds. Click it into the lower anchors and look for the green-means-go indicators, or install with a seat belt. Dual bubble-level indicators confirm the correct angle, and the steel stability leg can fold under when not in use. Easy-release buttons make the car-to-car transfer a snap, so you can spend less time fussing and more time enjoying the ride.
