Video Review: See What Makes the Nuna PIPA Urbn Flex a Smart Travel System

Parenting means being ready for anything: a car seat meltdown, a last-minute ride in Grandma’s car or an airport sprint with baby on one hip and luggage in tow. That’s when gear that adapts to real life—like a baseless car seat you can install in seconds—really comes through. The Nuna PIPA urbn flex system does exactly that, giving you flexibility without the extra bulk.

Lightweight and ready to roll, this all-in-one travel system includes the ultra-light PIPA urbn infant car seat and a compact stroller frame that’s easy to carry and break down with one hand. Want to use it past the baby stage? Just add the Nuna Flex stroller seat (sold separately), and it’ll keep up with your kiddo until around age six (or 50 pounds).

Why you may want a car seat and stroller combo 

A travel system—aka a car seat that clicks into a stroller or stroller frame—can simplify your days. While it may not be an absolute must for everyone, having a corresponding stroller for your car seat to safely and seamlessly fit into (without ever having to take your baby out of the seat) can certainly be helpful.

And in the PIPA urbn flex’s case, you can go from car to stroller to rideshare—and back again—in just a few seconds, keeping the process quick and painless no matter where the day takes you. It's especially helpful in the early months when you're adjusting to new routines and want fewer steps in the mix. And since you can add the Nuna Flex stroller seat when your baby outgrows the infant car seat, the PIPA urbn flex system won’t be a one-year wonder. 

What sets the PIPA urbn infant car seat apart 

Lots of car seats offer convenience, but the PIPA urbn is built for maximum mobility. Here’s what sets it apart: 

• No base required: The built-in pipaFIX rigid latch system clicks directly into your car’s anchors—no base or seatbelts needed. That’s especially helpful if you’re switching between vehicles or hopping in a rideshare, since you won’t have to haul around a bulky base or deal with heavy gear. See how Neeli installed hers at 1:08.

• Simple setup: Just click it in, make sure the level line is parallel with the ground, check that the color-coded indicators switch from red to green, and you’re good to go. See the color indicators for yourself at 1:15.

• Featherweight design (0:54): At just seven pounds (excluding the canopy and inserts), the PIPA urbn is one of the lightest car seats out there, making it easier to carry your baby through errands, daycare drop-offs and everything in between.

• Swift transitions (1:33): A one-handed latch release makes it simpler to lift the car seat out of the car or off the stroller, even when you’re juggling a toddler, a pet or a bag (or three). 

• Everyday extras: Magnetic buckle holders that keep straps out of the way (1:43), a full-coverage UPF 50+ canopy and flip-out eyeshade (1:55), a pull-down privacy drape (2:00) and a peekaboo window  (1:58) help handle the little surprises—so you can feel ready for whatever the day brings.

• Safety + comfort (2:04): Aeroflex foam and side-impact protection help keep your baby safe, while the Merino wool and TENCEL lyocell headrest and inserts keep things cozy. Bonus: Everything’s machine washable, because messes happen.

Why the PIPA flex stroller frame stands out

If you’d like to see how you can turn the PIPA urbn infant car seat into a super maneuverable stroller, jump to 2:32 in Neeli’s review and read on for some extras that make the PIPA flex stroller frame stand out:

• Travel-friendly build (2:39): At just over 11 lbs, this carbon fiber reinforced aluminum frame is strong but ultra-portable. It folds up fast with one hand, stands on its own when folded (no awkward balancing act) and comes with a travel bag to make getting from A to B more manageable.

• Smooth strolling: All-wheel suspension and puncture-proof tires help make curbs, playground gravel and other uneven terrain a lot more manageable. Watch how easily Neeli navigates a bumpy city sidewalk at 2:53.

• Customizable comfort (2:58): A three-position handlebar lets caregivers of all heights find their perfect push position.

• Storage that works (3:05): A roomy underbasket holds up to 22 lbs (hello, diaper bag + snacks). It even includes a hidden pocket in the basket designed for a tracking device—because whether you're navigating a theme park or swapping strollers with a caregiver, a little extra peace of mind can go a long way.

• Bassinet compatible: If you’re looking to use the stroller frame from day one, the flex also fits with the Nuna SWIV and TRIV series bassinet, giving you more flexibility (and a cozy spot for newborns who need to lie flat). 

Who we recommend the PIPA urbn flex system for

This system could be a good fit if you’re looking for gear that’s easy to use, especially during those early months when routines are still taking shape. It’s especially useful for:

• Families who regularly switch cars: The no-base install is helpful for rideshares, grandparents’ cars or caregivers.

• Parents in smaller spaces: Lightweight and compact, it’s easier to carry upstairs or store in tight entryways or trunks.

• Those who want fewer steps: The simple fold and one-handed releases can make getting out the door feel less overwhelming.

• People planning ahead: Add the Flex stroller seat later, and you’ll keep using the system well beyond the infant stage.

And if you love the clean, luxe design Nuna is known for, this system offers a more accessible entry point at $750, so it’s a great place to start. So, if you’re hoping to keep your setup lightweight, low-fuss and adaptable, the PIPA urbn flex system covers a lot of bases, well, without an actual base.
