Quick Answer
The Nuna TRIV lx and the UPPAbaby Cruz V3 are both single strollers built for children from birth to 50 lbs, but they come from different brands with different car seat ecosystems. The TRIV lx is the lighter of the two at 21.1 lbs, with a near-flat recline that converts to a newborn carriage position and a 22 lb basket. It's open for pre-order now, with availability starting September 15, 2026. The Cruz V3 is in stock now, weighs 26.5 lbs, has a lay-flat seat with an included infant insert, a 30 lb basket, and connects directly to UPPAbaby's own Mesa V3 and Aria infant car seats.
Nuna TRIV lx vs. UPPAbaby Cruz V3: Compact vs. Full-Size, Which One Wins?
The Nuna TRIV lx and the UPPAbaby Cruz V3 both aim at the same kind of shopper: someone who wants a single everyday stroller without the size or price of a full expandable system. Since they come from two different brands with two different car seat lines, the choice often comes down to which ecosystem you're already building toward, on top of the size and timing differences below.
What the TRIV lx Brings
The TRIV lx just became available as a standalone stroller for the first time, no longer requiring a bundled Nuna car seat purchase. At 21.1 lbs with the canopy, insert, and arm bar attached, it's a genuinely compact stroller, with a near-flat recline that converts to a newborn carriage position for use from birth without a separate bassinet.
Its frame is carbon fiber reinforced aluminum, paired with large, never-flat tires and all-wheel suspension. The basket holds up to 22 lbs with a built-in tracking device pocket, and it connects to all Nuna PIPA series car seats and the SWIV and TRIV series bassinet through a MagneTech Secure Snap magnetic buckle.
What the Cruz V3 Brings
The Cruz V3 is UPPAbaby's lighter, more compact alternative to the Vista V3, without needing a double stroller option. The seat lays completely flat and comes newborn-ready out of the box with an included infant insert, so there's no separate bassinet purchase required. It weighs 26.5 lbs total (17 lbs frame, 9.5 lbs seat), folds in one step into an ultra-compact, self-standing shape, and carries a 30 lb basket.
Comfort comes from dual-spring FlexRide suspension, and it connects directly, with no adapters, to UPPAbaby's own Bassinet V3, Mesa V3, and Aria infant car seats. Adapters are sold for other major brands including Nuna, Cybex, Maxi-Cosi, Chicco, and Peg Perego, so a Nuna PIPA seat can attach to the Cruz V3 with the right adapter, just not without one the way it does on the TRIV lx.

The Ecosystem Question
Since the TRIV lx and the Cruz V3 come from different brands, the more useful question for a lot of families isn't which spec sheet reads better, it's which car seat ecosystem you're already using or planning to buy into. If you already own or plan to buy a Nuna PIPA car seat, the TRIV lx's no-adapter connection is the simpler path. If you're set on Mesa V3 or Aria, the Cruz V3 is the direct match, and it can still take a Nuna PIPA seat with the right adapter if you decide to mix brands.
