The Nuna® flex system makes the everyday parenting juggle a whole lot easier. It starts with the innovative PIPA™ urbn car seat: a plush, lightweight and newborn-ready seat that installs securely and swiftly without a base using a rigid LATCH system. When it's time for a walk, you can move the car seat from the vehicle and into the lightweight stroller frame with just a couple clicks for a fuss-free transition. The stroller's never-flat tires and all-wheel suspension deliver a smooth ride on sidewalks, and the frame folds down in seconds when you're done. And with carbon-reinforced frames, premium fabrics and leatherette-finished handles, the whole system looks as sleek as it functions.
