The Nuna TRIV offers similar features to the best-selling Nuna MIXX Next—at a fraction of the size.

Like the MIXX Next, the TRIV has a reversible seat, ample storage space and easy car seat compatibility using Nuna's innovative ring adapter. Yet it manages to be 7 pounds lighter and significantly more compact than the MIXX Next, making it easier to carry and stash in your trunk.

But bigger is better in some ways: The MIXX Next is more versatile, offering more seating options and larger wheels for a smoother ride over any type of terrain.

Both strollers are available at Strolleria, and the price difference between them is $100.

So which is better: the Nuna TRIV or the Nuna MIXX Next? We'll review the differences between the two strollers, along with their pros and cons, in this comparison.

This post references the most recent versions of the MIXX Next and TRIV, both of which were updated in 2021.

Nuna TRIV vs. Nuna MIXX Next Stroller Comparison

Nuna TRIV vs. Nuna MIXX Video

Watch the video below for a comparison of the Nuna TRIV with the Nuna MIXX. 

While the video depicts the prior-model MIXX, most of the features apply to the newer MIXX Next. See this Nuna MIXX vs. Nuna MIXX Next comparison for an overview of what's new for the Next model, including a more compact, standing fold and improved suspension.


The TRIV is Nuna's most compact stroller to date—weighing less than 20 pounds, or just 14.6 pounds when using only the frame and car seat.

You'll only need one hand to fold the TRIV or to quickly attach a Nuna infant car seat using the included ring adapter (which folds in half, too).

The TRIV offers comfort features like an adjustable footrest and handlebar, a three-position recline, and a breathable merino wool insert that can be removed to reveal a mesh seat back.

In 2021, the TRIV was updated to include a magnetic harness buckle and zippered seatback storage pocket. Also new: a bassinet sold separately that can be used as an overnight sleeping option for your newborn.

Nuna MIXX Next

The Nuna MIXX Next is a stylish yet sturdy stroller for all your outings, whether you're headed on an all-terrain adventure or just a stroll around the block.

Tough foam-filled wheels with all-wheel suspension allow the MIXX Next to tackle any terrain, while features like a five-position recline, adjustable handlebar and ventilated seat back add comfort for both parent and child.

The Nuna MIXX Next is simple to fold with the seat facing either direction and fabric protected. When folded, the stroller locks automatically and can stand for easier lifting or trolleyed for transport. 

Create a travel system by attaching an Nuna infant car seat using the included ring adapter, or create a comfy newborn stroller adding the MIXX bassinet, which is approved safe for overnight sleeping.

Updated in early 2021, the MIXX Next model has a smaller, standing fold; a smoother ride with enhanced suspension; and a new magnetic harness buckle that makes it a snap to buckle your child.

See this Nuna MIXX vs. Nuna MIXX Next comparison for more details.

Nuna TRIV vs. Nuna MIXX Price

The Nuna TRIV costs $100 less than the Nuna MIXX Next. Both strollers include the ring car seat adapter, but the TRIV also includes a rain cover, which is sold separately for the MIXX for $39.95.

  • Nuna TRIV: $699.95
  • Nuna MIXX Next: $799.95

Nuna TRIV vs. Nuna MIXX Next Weight and Dimensions

The Nuna TRIV is more than 8 pounds lighter than the MIXX Next, thanks to its smaller, lighter wheels and reduced footprint.

The TRIV is also more compact for navigating tight spaces, with its reduced width of 3.5 inches. And compared with the MIXX Next, the TRIV is also couple inches smaller (in length, width and height) when folded.

    Nuna TRIV vs. Nuna MIXX Next Wheels and Maneuverability

    If you're looking for a stroller to tackle tough terrain, the Nuna MIXX Next is your best bet. The MIXX Next has chunky wheels with robust all-wheel suspension, which help the stroller push through grass, gravel and snow.

    The TRIV also has all-wheel suspension as well as spring suspension underneath the seat to help absorb shock, but the rear wheels are significantly smaller than those on the MIXX Next. As a result, the TRIV is best-suited for neighborhood walks and errands rather than all-terrain uses.

    Both strollers feature rubber, foam-filled wheels for maximum durability.

    Wheel Size

    • TRIV: 7" front wheels, 7.5" rear wheels 
    • MIXX Next: 7.5" front wheels, 11" rear wheels 

    Nuna TRIV vs. Nuna MIXX Stroller Comparison

    Nuna TRIV vs. Nuna MIXX Next Seat

    Most Nuna strollers, including the MIXX and TRIV, feature a removable seat insert that can be removed in warm weather to reveal a mesh back.

    The TRIV seat insert is made with merino wool, a natural fabric that helps to keep your child stay warmer in the winter and cooler in the summer. Merino wool also has bonus properties, like being soft, hypoallergenic and environmentally-friendly.

    Both strollers have a no-rethread harness that slides up and down, making adjustments fast and easy as your child grows taller.

    The TRIV seat is about 2 inches taller than that of the MIXX Next, providing a little extra headroom for a growing toddler, while the TRIV sits lower to the ground than the MIXX.

    Seat Size

    • TRIV: 21" from seat to canopy, 17" from seat to footrest
    • MIXX Next: 19" from seat to canopy, 17" from seat to footrest

    Seat Height

    • TRIV: 20" from floor to seat
    • MIXX Next: 22" from floor to seat

    Nuna TRIV vs. Nuna MIXX Next Configurations

    Both the TRIV and MIXX Next have a reversible seat, which folds with the stroller regardless of the direction it's facing.

    Both strollers also offer the option of attaching a bassinet, which can also be used inside your home (with the MIXX also offering a bassinet stand). 

    Unlike car seats, which aren't safe for extended naps, the MIXX bassinet is approved for overnight sleeping, so it can be used at your bedside or weekend trips away. Plus, the bassinet offers more space and ventilation than a car seat, which tend to make babies hot.

    And while the TRIV offers three recline positions, the MIXX Next has five positions to help your child find a comfortable angle whether she's napping or exploring the world.

    How to Fold Nuna TRIV vs. Nuna MIXX Next

    Both strollers are easy to fold and stand when folded for easier pickup and lifting into the car. With the Nuna TRIV, you can use one hand to fold the stroller and the other to hold your baby. Folding the MIXX Next is also simple, but you'll need both hands.

    How to Fold Nuna TRIV

    To fold the Nuna TRIV, first push the small button within the recline lever, then pull the lever to fold the seat into the frame.

    Simply pull up on the strap integrated into the frame, and the stroller instantly collapses. The TRIV ring adapter folds in half alongside the stroller, a feature not seen on any other Nuna strollers.

    See this video for a look at folding the Nuna TRIV.

    How to Fold Nuna MIXX Next

    To fold the Nuna MIXX Next, first pull the lever on the back of the seat to fold it into the frame. Then pull the triggers on both side of the frame to lower it into place.

    While the MIXX Next folds to a flat position, you can rotate the stroller until it's standing upright or trolley it like a suitcase when folded. To unfold the MIXX, undo the lock and lift it back into place. The ring adapter also folds with the MIXX, but unlike the TRIV, the adapter itself does not fold.

    See how the Nuna MIXX Next folds in this video.

    Car Seats Compatible with Nuna TRIV and Nuna MIXX Next

    Both the Nuna TRIV and Nuna MIXX Next are compatible with Nuna's PIPA series of infant car seats using the ring adapter included with purchase:

    Learn about the five models—which differ in price, features, base and installation method—in this Nuna PIPA Series comparison.

    With both the TRIV and MIXX Next, attaching a car seat to the stroller doesn't get much easier. You'll need only one hand to snap the car seat into the ring adapter and one hand to release the car seat by pressing a large button on the back.

    The ring adapter design is unique to Nuna, so neither the MIXX Next nor TRIV can be used with other brands of car seats.

    Nuna TRIV vs. Nuna MIXX Next Accessories

    Accessories help customize your stroller for the weather or the age of your child. Currently, Nuna offers far more accessories for the MIXX Next than the TRIV (we'll update this post if new accessories become available).

    The TRIV comes with a rain cover to protect your child from the elements, and now also has a bassinet option. Otherwise, the only TRIV accessory is the universal travel bag that fits all Nuna strollers.

    Nuna TRIV vs. Nuna MIXX Next Stroller Comparison

    Nuna MIXX Next


    • Larger, tougher wheels with all-wheel suspension provide a smoother, easier push over rough terrain
    • Storage basket offers more space for diaper bag and necessities
    • Offers five recline positions, compared to three for TRIV
    • Offers more color choices and accessories

    • Requires two hands to fold
    • Ring adapter folds while attached to the stroller but does not fold in half


    The choice between the Nuna TRIV and the Nuna MIXX Next may be one between convenience and versatility.

    The TRIV is more convenient because it's lighter and more compact than the MIXX Next. If you're always on the go, you'll value the TRIV for its one-handed fold and easier carrying. And if your strolls are typically limited to errands and neighborhood walks, you may not mind that the TRIV wheels are small and not as rugged than those on the MIXX Next.

    The MIXX Next is the better choice for families who often embark on long walks or encounter rough terrain, like grass, gravel, sand and snow. The MIXX Next provides a smoother ride, thanks to its larger, tougher wheels. Plus, the stroller offers more storage and added recline positions.
