Quick Answer
The UPPAbaby Kona and the Nuna TRIV Next are both compact, everyday strollers built for children from birth to 50 lbs, but they come from different brands with different car seat ecosystems. The TRIV Next is available now, with a near-flat recline that converts to carriage mode, never-flat airless tires, and direct connection to Nuna PIPA series car seats with no adapters. The Kona is UPPAbaby's newly announced mid-size stroller, weighing around 21 lbs with a one-hand fold that works in either seat direction. It opens for pre-sale August 2, 2026, and ships September 29, 2026.
UPPAbaby Kona vs. Nuna TRIV Next: Which Everyday Stroller Fits Your Family?
The Nuna TRIV Next has built a loyal following as an everyday city stroller, and the new UPPAbaby Kona is entering a similar space from a different brand ecosystem entirely. Since these come from two different companies with two different infant car seat systems, the decision often comes down to which ecosystem you're already in, or planning to build toward. Because the Kona was only announced in May 2026 and won't ship until late September, some of this comparison reflects what UPPAbaby has confirmed publicly rather than side-by-side testing, which is worth keeping in mind.
What the TRIV Next Brings
The TRIV Next is built as a natural city stroller: a compact fold, a seat that faces and folds both ways regardless of which direction your baby is facing, and an all-season seat that converts to breathable mesh for summer. It covers children from birth to 50 lbs, with a near-flat recline that converts to a carriage-style position for extra newborn coziness, plus calf support that raises to match.
It connects directly to Nuna PIPA series car seats with no adapters needed, using a self-guiding MagneTech Secure Snap magnetic buckle and a 3 to 5-point no-rethread harness. The wheels are never-flat airless tires, paired with front swivel locks and quick-release wheels for an even more compact fold. The canopy is UPF50+ and water-repellent, with multiple windows and mesh panels for warm weather. It comes with a carry bag included, leatherette accents on the pushbar and armbar, and a ring adapter in the box for building a travel system.
What the Kona Brings
The Kona is UPPAbaby's new mid-size stroller, unveiled at the 2026 ABC Kids Expo under the tagline "Compact Without Compromise." At around 21 lbs, it's built around a lightning-fast one-hand fold that works whether the seat faces forward or backward, with a slim frame meant to smooth out transitions from subway stairs to sidewalk strolls. It covers birth to 50 lbs, with a full recline, an adjustable footrest, and a basket UPPAbaby has positioned at roughly 30 lbs.

The Ecosystem Question
Since the Kona and the TRIV Next come from different brands, the more important question for a lot of families isn't which stroller has the better spec sheet, it's which car seat ecosystem you're already using or planning to buy into. The TRIV Next's no-adapter connection to Nuna PIPA series car seats is fully documented today. UPPAbaby hasn't yet published the Kona's car seat compatibility details, so if you're building a travel system around a specific infant car seat, that's worth confirming before you commit to either stroller.
Fold Mechanics: What's Confirmed on Each Side
The TRIV Next's fold is fully documented: it folds easily with one hand, stands on its own once collapsed, and its quick-release wheels let the fold get even more compact when needed. The Kona's fold is described similarly, a lightning-fast one-hand fold that works whether the seat faces forward or backward, but UPPAbaby hasn't yet published exact folded dimensions or independent testing of how it holds up over repeated daily use. That's the kind of detail that tends to firm up in the weeks right before a stroller actually ships.
