The Nuna PIPA aire rx & DEMI Next Travel System in Caviar with Chocolate is the complete go-anywhere solution for growing families. Pairing one of the lightest full-featured infant car seats on the market with a stroller that adapts from single to double, this duo is designed to take you from newborn days through toddlerhood with ease.
DEMI next Stroller
With 25+ modes, the DEMI next converts from a single stroller to a double or twin and includes a rider board for siblings (sibling seat sold separately). Folding, flipping the seat, and converting to bassinet or car seat mode is super easy, and four recline positions plus a one-hand adjustable calf support and footrest keep every ride just right as baby grows. Custom Dual Suspension™ and foam-filled tires handle any terrain, while self-guiding MagneTech Secure Snap™ buckles and a quick-release 3 to 5-point harness make getting in and out a breeze. The water-repellent UPF 50+ Aire Protect Canopy™ features a privacy drape and ventilation panels, and the all-season Merino wool seat insert converts to mesh in summer. A large 22 lb basket, adjustable leatherette-accented pushbar, and included rain cover complete an incredibly well-thought-out stroller.
Rider Board
The included rider board positions your child between your arms for closeness and attaches to the stroller’s lower seat mounts with ease. It holds up to 50 lbs, has two swivel wheels for smooth maneuvering, folds with the stroller, and tucks neatly into the basket when not in use.
PIPA aire rx Infant Car Seat
At just 6.2 lbs, the PIPA aire rx is lightweight with zero compromises. It installs with or without the base using a vehicle seat belt, making it ideal for city living, taxis, and FAA-certified aircraft use. True Lock™ installation with the included RELX base takes just 5 seconds, while Side Impact Protection and Aeroflex™ foam minimize force transferred to baby. A 3-position height-adjustable headrest, 5-point harness, integrated magnetic buckle holders, and Tailor Tech™ memory foam seat panel ensure a secure and comfortable fit at every stage. The UPF 50+ canopy with flip-out eyeshade, Sky Drape™ privacy panel, and machine-washable fabrics make daily use effortless, and GREENGUARD Gold Certification confirms it meets some of the world’s most rigorous chemical emissions standards. Infant inserts are crafted from Merino wool and TENCEL™ lyocell — soft, moisture-managing, and eco-friendly.
RELX Base
The RELX base features a True Lock™ rigid latch that is 50% stronger than a typical belt latch, along with 4 bubble-free recline positions and a 4-position rigid latch for a precise vehicle fit. An integrated anti-rebound panel and telescoping steel stability leg with crumple zone add an extra layer of rear-facing security, and colored installation indicators confirm correct connections at a glance. The low-profile design makes loading easy, and the latch and stability leg stow neatly when not in use.
