The Nuna MIXX Next paired with the PIPA RX Infant Car Seat in Granite is the complete travel system designed to carry your baby from the hospital to their first adventures — and everywhere in between. This bundle includes the MIXX Next stroller, PIPA RX infant car seat, RELX base, and ring adapter for seamless one-click attachment, road-tested in our boutique from day one.

MIXX Next Stroller — 4 Modes, One Compact Fold

The MIXX Next adapts as your family grows — use it as a travel system with the PIPA RX, attach a bassinet for newborns, or switch the seat to parent-facing or world-facing mode. Rear-wheel Free Flex suspension™ and front-wheel progressive suspension handle any terrain, while a true-flat sleeper recline, five-position one-hand recline, and MagneTech secure snap™ buckle make every ride comfortable and effortless. The one-piece compact fold stands on its own with an automatic quick-click fold lock and trolley function.

PIPA RX Infant Car Seat

The PIPA RX is made entirely from materials free of fire retardant additives — from fabric to foam. It installs in seconds with the RELX base or directly via the belt path on the shell with no base required, and is FAA certified for aircraft use. It fits 4–32 lbs and up to 32 in, with a full-coverage UPF 50+ canopy, Sky drape™, side impact protection, organic jersey insert, and a luxe leatherette carry handle. Complimentary car seat safety installations and safety checks by our trained staff for all purchased seats.

RELX Base

The RELX base installs in 5 seconds with an open belt path and True lock™ rigid latch — steel-reinforced with indicators that turn green when secure. Four-position on-the-go recline with bubble-free angle guides, an anti-rebound panel, crumple zone in the stability leg, and a locking 3-piece steel stability leg that fits most vehicles including middle seats.

What's Included

Every bundle includes the MIXX Next stroller frame and seat, PIPA RX infant car seat, RELX base, ring adapter, and bamboo blend seat insert with a 3-year stroller warranty and 2-year car seat warranty.
