Flex System Seat by Nuna

Meet the add-on seat that gives your PIPA urbn flex system a longer life and your baby a front-row seat to the world. Designed to click on when your infant car seat days are over, or during as an alternative, this seat keeps the ride going without skipping a beat (or a step).

The recline is smooth, the canopy is generous, and the comfort? Fully upgraded. And thanks to the same featherlight carbon fiber reinforced frame, you still get that smooth fold and carry you signed up for at the start.

While others stall out after months, this system just gets smarter. No gimmicks. No trade-offs. Because growth doesn’t come with an off switch.
