Quick Answer
The Nuna TRIV lx and the Mixx Next are both premium Nuna strollers, but they're built for different footprints. The TRIV lx is the compact option at 21.1 lbs, with a near-flat recline that converts to a newborn carriage position, a carbon fiber reinforced frame, and a 22 lb basket. It's open for pre-order now, with availability starting September 15, 2026. The Mixx Next is Nuna's full-size everyday stroller, with a true-flat recline usable from birth, a reversible seat, four use modes including bassinet and PIPA car seat, and it's in stock now.
Nuna TRIV lx vs. Mixx Next: Which Nuna Stroller Fits Your Family?
Nuna's lineup covers a wide range of everyday use cases, and the TRIV lx and the Mixx Next sit at two different points on it. Both connect to the same Nuna car seat ecosystem, so the decision usually comes down to size, fold, and how flat you need the seat to go for a newborn.
What the TRIV lx Brings
The TRIV lx is Nuna's compact daily stroller, and it just became available as a standalone frame for the first time instead of only bundled with a car seat. It weighs 21.1 lbs with the canopy, insert, and arm bar attached, and offers a near-flat recline with calf support that raises to convert the seat into a newborn carriage position, usable from birth without a separate bassinet.
The frame is carbon fiber reinforced aluminum, paired with large, never-flat tires and all-wheel suspension for a smoother ride than most compact strollers manage. The basket holds up to 22 lbs and includes a built-in tracking device pocket. It connects to all Nuna PIPA series car seats and the SWIV and TRIV series bassinet, using a MagneTech Secure Snap magnetic buckle.
What the Mixx Next Brings
The Mixx Next is Nuna's most complete single stroller, built for families who want one stroller to handle newborn through toddler without switching setups. It offers four use modes: parent-facing, world-facing, with a bassinet, or with a Nuna PIPA series car seat, using an included ring adapter. Its true-flat recline means it's ready for a newborn on its own, no separate bassinet purchase required.
It's noticeably larger than the TRIV lx, at roughly 28 lbs, with a bigger everyday footprint, rear-wheel Free Flex suspension, front-wheel progressive suspension, foam-filled tires, and an all-season seat. The fold is a one-piece compact fold that stands on its own regardless of which direction the seat is facing, and the basket is sized larger than the TRIV lx's for families who carry more gear on a typical outing.
