Nuna PIPA urbn flex system | New Nuna Product Review 2025
Nuna is one of the most beloved luxury baby brands worldwide—and for good reason. Nuna puts safety, quality, performance, and comfort at the forefront of every design. Year after year, their products evolve to meet the changing needs of modern families.
New releases from Nuna are always met with excitement and anticipation, and the new Nuna PIPA Urbn Flex System is no exception. This innovative one-box, snap-and-go travel system is perfectly suited for busy city and suburban families alike. In this review, we’ll dive into everything you need to know about the Nuna PIPA Urbn Flex System, how it works, and how it compares to other popular travel systems on the market.

What is the Nuna PIPA urbn flex system?
The Nuna PIPA Urbn Flex System is a true one-box travel system designed for life on the go.
A travel system refers to an infant car seat and stroller that pair seamlessly for quick transitions between car and stroller—no need to unstrap or wake a sleeping baby. This is a huge advantage for parents constantly moving in and out of the car, especially during the newborn stage when uninterrupted sleep is precious.
Traditionally, families have opted for a full-size stroller with a matching infant car seat, expecting it to last through multiple stages of childhood. However, with so many stroller types available today—compact, all-terrain, travel, jogging, and modular—modern parents often find themselves using multiple strollers to fit their unique routines.
Active families might choose an all-terrain stroller for adventures and a lightweight stroller for errands or travel. Others may begin with a full-featured stroller and later invest in a compact model for family trips.
The challenge many first-time parents face is that it’s difficult to know exactly what life with baby will look like until baby arrives. That’s why flexibility matters. While many gear decisions can be made later, every family needs a newborn-safe car seat and wheels from day one.
The Nuna PIPA Urbn Flex System provides exactly that—a thoughtfully designed starter system that includes only what parents need from the first trip home from the hospital, while leaving room to grow and customize as family needs evolve.

What Makes the Nuna PIPA urbn flex system Unique?
This system comes with the PIPA urbn infant car seat and the new Flex stroller frame, creating a lightweight, ultra-portable snap-and-go setup perfect for everyday use.
What truly sets the PIPA urbn apart is its baseless installation. It features built-in rigid LATCH connectors, offering the most secure and convenient baseless install currently available. This innovation is a game-changer for city parents, rideshare users, frequent travelers, or families using multiple vehicles.
When paired with the Flex stroller frame, the system provides effortless portability from birth to roughly one year.
The Flex stroller frame is also modular—it can be paired with the Nuna SWIV/TRIV Bassinet for premium newborn comfort and later upgraded with the reversible flex toddler stroller seat (sold separately) when the time is right. This flexibility allows parents to buy only what they need, when they need it, making the system both practical and budget-conscious.

Nuna PIPA urbn flex system with Bassinet
While a travel system offers easy, on-the-go transitions, it’s important to remember that babies should spend limited time in an infant car seat. For optimal spine development and safe breathing, newborns benefit most from lying flat whenever possible.
Pairing the Nuna PIPA Urbn Flex System with a bassinet creates the most comfortable and developmentally supportive environment for your newborn.
The Nuna SWIV/TRIV Bassinet is fully compatible with the Flex stroller frame and is ideal for longer walks or daily strolls. It can also serve double duty as a bedside bassinet for overnight sleep or a secondary nap station during the day. The included stand allows the bassinet to transition easily from stroller to home use—so if baby falls asleep on your walk, you can simply lift the bassinet off the frame and let your little one continue napping safely indoors without interruption.
This flexibility makes the Flex + Bassinet combination one of the most versatile newborn stroller setups available, blending Nuna’s signature comfort and convenience for both baby and parent.

Nuna PIPA urbn flex system with flex stroller seat
Once your baby outgrows the infant car seat or bassinet, the next stage in your travel system journey is the Flex Stroller Seat.
Sold separately, the Flex Seat allows parents to hold off on the extra expense until it’s truly needed—no need to store extra parts you won’t use during the first few months. When your little one is ready to sit up and explore, the Flex Seat seamlessly attaches to the same Flex frame, transforming your beloved newborn setup into a full-featured toddler stroller.
The seat is reversible, allowing your child to face you for bonding or face forward to explore the world. It includes all the premium details parents expect from Nuna—high-quality fabrics, extra large sun canopy, and comfort-focused design—providing a safe, stylish, and roomy ride for toddlers up to 50 lbs.
The Flex Stroller Seat completes the modular system, extending the life of your investment and giving families a travel system that grows with their child from newborn through toddlerhood.
Comparing the Nuna PIPA urbn Flex system to Popular Travel Systems

Nuna PIPA urbn flex system vs. Nuna TRVL lx
The Nuna TRVL Lx stroller can also be paired with any Nuna PIPA infant car seat, connecting directly without an adapter. It features a fully flat, newborn-friendly recline, allowing comfortable use from birth without additional accessories.
However, the TRVL Lx has a forward-facing seat only and a smaller storage basket compared to the Flex System. The Flex’s basket holds up to 22 lbs, which is 12 lbs more than the TRVL Lx. The key difference is that the Flex is modular, meaning it can pair with a bassinet or reversible toddler seat offering versatility and premium comfort at every age and stage.

Nuna PIPA urbn flex system vs. Nuna TRIV Next
The Nuna TRIV Next is a compact mid-size stroller that blends portability with full-size features. Like the Flex, it pairs easily with all Nuna PIPA infant car seats and the Nuna SWIV/TRIV Bassinet.
The major difference is that the TRIV Next comes boxed with its stroller seat, making it an all-in-one purchase designed for long-term use up to 50 lbs. The Flex System, on the other hand, sells the seat separately, allowing parents to spread out purchases or transition to a different setup after the infant stage if they prefer.

Nuna PIPA urbn flex system vs. the Doona Infant Car Seat/Stroller
The Doona Infant Car Seat Stroller has become a favorite among city and travel-loving families for its unique all-in-one design—it transforms from car seat to stroller in seconds.
While incredibly convenient, the Doona’s integrated design makes it heavier to lift in and out of vehicles, especially as baby grows. It also shares the same limited lifespan as most infant car seats—usable from birth to around one year. Parents will need to purchase both a new stroller and car seat afterward.
In contrast, the Nuna PIPA Urbn Flex System can grow beyond the first year with the addition of the toddler seat, providing extended use up to 50 lbs.
Additionally, the Doona keeps baby in a semi-upright position, whereas the Flex System’s compatibility with a flat bassinet offers a more developmentally supportive option for newborns—especially for families who walk frequently or spend extended time out and about.

Is the Nuna PIPA urbn flex system worth it?
The Nuna PIPA Urbn Flex System is a smart, future-focused choice for parents seeking safety, convenience, and long-term value in a premium travel system. Its lightweight, baseless installation car seat and modular stroller frame deliver flexibility and simplicity without compromise.
Whether you’re a first-time parent building your baby gear collection or a seasoned caregiver looking for a streamlined, on-the-go solution, the Nuna PIPA Urbn Flex System offers the perfect balance of luxury and practicality—designed to grow with your baby every step of the way.
