The Nuna PIPA Urbn & MIXX Next Travel System in Granite pairs one of the lightest baseless infant car seats on the market with a versatile 4-mode stroller — road-tested in our boutique and built for families who move through the world with intention. From rideshares to park runs, this system handles it all from birth through the toddler years.
PIPA Urbn Infant Car Seat — Baseless & Built for Life on the Go
At just 7 lbs, the PIPA Urbn installs in seconds using the integrated pipaFIX™ rigid latch — no base required, making it the ideal companion for taxis, rideshares, and frequent flyers. The auto-reclining foot ensures proper vehicle installation every time, while a European belt path offers an additional installation option. Aeroflex™ foam absorbs and minimizes force transferred to baby, and side impact protection adds an extra layer of confidence. The Sky drape™ canopy pulls down smoothly and attaches silently with magnets, while the full-coverage UPF 50+ canopy with flip-out eyeshade and XL peek-a-boo window keeps baby shielded in any light. Merino wool and TENCEL™ lyocell infant head and body inserts, GREENGUARD Gold Certification, and FAA certification for aircraft use round out a seat engineered for the modern family. Fits 4–35 lbs and up to 32 inches. Not compatible with PIPA™ series base or RELX™ base.
MIXX Next Stroller — Four Modes, One Compact Fold
The MIXX Next adapts as your family grows — configure it as a travel system, attach a bassinet for newborns, or flip the seat to parent-facing or world-facing mode with ease. Rear-wheel Free Flex suspension™ paired with front-wheel progressive suspension delivers a cushiony smooth ride across any terrain, while tough rubber foam-filled tires handle city sidewalks and park paths alike. A true-flat sleeper recline ensures newborn comfort from day one, and the five-position recline adjusts with one hand as baby grows. The MagneTech secure snap™ buckle self-guides and locks automatically, and a no-rethread harness makes adjustments quick and frustration-free. The all-season seat features a cozy knit panel for winter that unsnaps to breathable mesh for summer, and the removable two-piece bamboo blend seat insert grows with baby through the toddler years. A UPF 50+ water-repellent extendable canopy with flip-out eyeshade and ventilation panel, height-adjustable leatherette push bar, one-touch rear braking, and a two-compartment basket with hidden zipper pocket complete the package. Stroller weighs 28.3 lbs; unfolds to 32.7"L × 23.6"W × 45.3"H and folds to 27.5"L × 23.6"W × 19"H.
