Nuna TRIV next

This reversible-seat city stroller folds flat with one hand in either seat direction, keeping its included PIPA ring adapter attached through the fold. Nuna's own advice is to ride in a PIPA car seat until around six months, since the seat only reclines to three positions.

What it does well

Folds flat one-handed even with the seat parent-facing
PIPA ring adapter is included and stays on through the fold
All-season seat converts to mesh for summer
Owners say it is light enough to lift into a small trunk and fold alone with one hand

What it gives up

Nuna recommends a car seat rather than the stroller seat until about 6 months
Only three recline positions
Published weight excludes the insert, arm bar and canopy (about 2.6 lb more)
Owners find the seat swallows small babies, with the harness straps reaching their faces

What owners say

The TRIV next is the stroller parents pick when a MIXX, Cruz or Vista feels like too much. It folds one-handed, lifts into a small trunk, and still has rubber wheels and a real basket, which is the gap it fills between travel strollers and full-size ones. It also flies well, gate-checked or sent through the airport scanner folded.

Babyhood tests it at both ends. The US seat does not recline flat, so newborns ride in a PIPA car seat or Nuna's SWIV & TRIV series bassinet (the LYTL), the only bassinet that fits and one owners found hard to get in 2025. When babies do move to the seat, small ones can look lost in it, with straps reaching their faces. Opinions on terrain and basket size are split: some owners keep it to paved paths and find the basket small next to the MIXX, others take it on gravel and cobblestones and call the basket roomy for its size. A few owners say it feels cheaper than a Silver Cross or UPPAbaby, while longer-term owners insist it is sturdy.

Daily life with several folds a day, in the city or in and out of a car, and a PIPA seat for the early months is its sweet spot. Parents who want a lay-flat seat from birth or who walk mostly on rough ground tend to be happier with something bigger.

What owners like

The one-handed fold is the main reason people choose it, and it makes getting a baby and a stroller onto a subway alone manageable.
Its in-between size wins over a lot of buyers: light enough to lift into a Mini Cooper or a sedan trunk, yet with rubber wheels and a proper basket, unlike a travel stroller.
Travels well. Parents gate-check it without damage, and folded it goes through the airport X-ray belt with the wheels still on.

Common complaints

The US seat does not lie flat, so for roughly the first 3 to 6 months you are using a PIPA car seat or Nuna's SWIV & TRIV series bassinet (the LYTL).
Nuna's SWIV & TRIV series bassinet, sold as the LYTL, is the only bassinet that fits; it costs extra, second-hand MIXX bassinets will not work, and it was sold out for months in 2025.
Small babies get swallowed by the big seat, and parents describe harness straps hitting the face or bending the ears until somewhere between 6 and 12 months.
Rough ground divides owners. Many call it a paved-sidewalk stroller that feels every crack and struggles on gravel or sand, while others take theirs on gravel, light trails and cobblestones without trouble.

Questions owners ask about the Nuna TRIV next

TRIV next or MIXX next?

Parents who chose the TRIV did it for the one-handed fold and the smaller, lighter package that fits a compact trunk. The main thing they gave up was a seat that lies flat for a newborn.

Does a newborn need the bassinet on the TRIV next, or will the seat do?

The US seat does not recline flat, so for the first few months parents use either a PIPA car seat on the included adapter or Nuna's SWIV & TRIV series bassinet, sold as the LYTL. That is the only bassinet that fits, MIXX bassinets do not, and stock ran out for months in 2025. One parent took a cheaper route with a third-party adapter for an UPPAbaby bassinet.

Is the TRIV next only for paved sidewalks?

Owners disagree. Many say it is best on pavement and that the small wheels feel every crack, though it does fine on grass. Others report no trouble on gravel, garden trails and European cobblestones.

Is the TRIV next basket roomy for a mid-size stroller?

It depends who you ask. Some owners call it large and easy to reach for a mid-size stroller, while others find it small next to a Vista or MIXX.

Does the TRIV next survive gate-checking and the X-ray belt?

Yes. Parents gate-check it, some without a bag, and report no damage, and folded it fits through the airport X-ray machine without removing the wheels.
