Best convertible stroller test Uppababy Vista V2

Parents / Leticia Almeida

Convertible strollers are kind of magical: They grow right along with your family, changing from a single stroller to a double stroller when you decide to have a second baby, and then back again when your older kid is over it. Some even accommodate a third kid! And all of this is with just one purchase (and maybe extra accessories along the way. But because these are a huge commitment, we tested just about every model we could find (17 and counting!) in our lab and at home with our own families, to bring you a list of the best convertible strollers on the market.

“Purchasing a stroller can be an investment, so having one that gives options to grow with your child, and with your family, can be a great choice,” explains Amanda Stovall, M.D., an Illinois-based board-certified pediatrician. At the same time, because these strollers must have strong frames that are big enough to fit two seats, you may eventually want to purchase a compact travel stroller too.

To find the best convertible strollers, we evaluated how easy they were to assemble as single strollers, how hard it was to add and take away a second seat, their maneuverability on various terrains, their design (for aesthetics, safety, and comfort), their value, and their durability once they left the lab and ventured into the real world.

Our Favorite Single-to-Double Convertible Strollers

Best Overall: UPPAbaby Vista V2 Stroller



Why We Like It: This smooth, beautiful ride is sturdy, even as you push around the weight of two kids and extra cargo.

But Take Note: Taller kids may eventually outgrow the canopy.

The UPPAbaby Vista V2 stroller earns the top spot on our list, not just because it earned high marks in the lab, but also because it's done brilliantly in the real world. We also see it all over New York City, carrying as many as three kids (with a ride-along board) and loaded up with bags.

In the lab it was intuitive to put together the first time, and we thought attaching the second toddler seat and swapping out the infant bassinet was a breeze. The seats can face forward or backward, and they tilt way back for sleeping littles. WE love the eye-catching, thick full-grain leather on the handlebars that come in a variety of shades, like saddle and chestnut. The handlebar’s height is also adjustable, so parents and caregivers of any height can push the stroller comfortably. And while there's a generous storage basket under the seats that holds up to 30 pounds (easily a diaper bag and a backpack), the tall parents on our team really appreciate that they never find themselves kicking it as they walk, which happens often with other strollers.

The extendable canopies offer kiddos UPF 50+ protection, while the mesh peekaboo windows provide airflow and visibility to kiddos (and peace of mind for adults). A five-point, no-rethread harness keeps littles strapped in securely for rides at any recline without hassle for adults.

We also put the Vista V2 through our maneuverability test, which includes pushing the stroller over different terrains, like carpet, hard floor, and even gravel, taking a brisk walk, and going up and down steps. The stroller was easy to push through the obstacle course, thanks to the stroller’s all-wheel suspension. Due to its size and the safety locking feature on the front wheels, we didn't enjoy pulling it up stairs, however.

In the real world, this stroller gave our kids a smooth, sturdy ride, and it's shown very little wear and tear over the past three months. The only drawback we've found is that taller kids will outgrow the use of the seat with the canopy, so be prepared to provide alternative sun and rain protection when they reach those new heights.

The Vista V2 is one of the most expensive single-to-double strollers we tested, but you get your money’s worth, and it might just be the only stroller your family needs.

Best Flexibility: Evenflo GOLD SensorSafe Pivot Xpand Smart Modular Travel System

Evenflo Gold SensorSafe Pivot Xpand,


Why We Like It: Its assembly took less than five minutes, and you can switch it into 22 different configurations of seats.

But Take Note: It bounces kids about on rough terrain, though not in a way that feels dangerous.

While the standard Evenflo Pivot Xpand didn’t blow us away in the lab, the Gold version was quite impressive right from the start, when it took us less than five minutes to put it together. Everything snapped into place with a loud click that let you know it was in securely.

And speaking of security, the Gold Pivot Xpand travel system comes with the SecureMax Instant Car Seat, which has the SensorSafe clip that can connect to a caregiver’s phone and alert them to potentially dangerous situations like overheating, accidental unbuckling, or an unattended child. You can switch it out to make room for two toddler seats, and the second seat (sold separately) doesn’t require the purchase of additional adapters. In total, there are 22 possible configurations of seats for this stroller.

We love the bright colors and a bold design of this stroller, which has easy-to-use buckles and clips, generous footrests, full recline options, and perfectly placed cup holders. The canopies have multiple positions to keep little ones safe from the sun or rain. In real world testing, the storage space under the seats fit a diaper bag as well as extra groceries, and our kids enjoyed the generous size of the seats, too. One small downside to the design is that we think the bumper bar might have to be removed completely in order to put some children in the stroller. We also felt a little wobble in the handle that, while not worrisome in a safety sense, made it clear this was not the sturdy luxury of the Uppababy.

Despite a couple of small issues, the Gold Pivot Xpand maneuvered beautifully in the testing lab’s obstacle course. The stroller features rear-wheel suspension and a front swivel wheel, allowing for smooth turns, no matter how tight or wide. It went over the bumps with little resistance, and was even easier to push when both seats were facing forward. In the real world, we found that this stroller is so lightweight that the rougher bumps jostled kids a lot, though not in a dangerous way. Still, the kids never complained, and the convenience of having a stroller that can switch from one to two seats was worth it.

The Details:

  • Dimensions: 49 x 26.5 x 56 inches (stroller), 26.5 x 16 x 26 inches (car seat)
  • Product weight: 28.6 pounds (stroller), 9.2 pounds (infant car seat), 8.7 pounds (base)
  • Child age/weight range: Birth to 55 pounds (toddler seat), 4 to 35 pounds and up to 32 inches tall (infant car seat)

Best for Travel: Baby Jogger City Select 2 Single-to-Double Modular Stroller

 Baby Jogger City Select 2 Single-to-Double Modular Stroller,


Why We Like It: It's lightweight, compact, and easy to fold and move the seats, making it the best for packing into a car.

But Take Note: In double stroller mode, you can't recline both seats.

If you have two kids close in age, the Baby Jogger City Select 2, which has more than 24 possible configurations, can accommodate them—and you can add a third on the ride-on board for triple the fun. It's sold as a single stroller or as a travel system with an infant car seat, and you can purchase a second toddler seat for it separately. What we really appreciated about this lightweight stroller in the real world is that it's quite compact and folds quickly, so it's a go-to choice when traveling somewhere by car.

Each seat has an adjustable five-point safety harness to keep little ones safe during rides. We love the stroller’s extended UV 50+ canopies, which provide good coverage to children, and peace of mind to adults, thanks to peekaboo windows for visibility and extra ventilation. The City Select 2 features a large storage basket under the seats that holds up to 15 pounds of essentials. We were able to fit a diaper bag in there with room to spare, and it didn’t weigh the stroller down. It also folds compactly in just one step for quick storage. One design flaw we discovered in the lab, though, was that with both seats facing forward, only the back seat reclines all the way, and the front seat does not.

When pushing the City Select 2, we liked the handlebar, which felt durable, comfortable, and controllable. This stroller weighs just under 27 pounds and features front-wheel suspension and all-terrain tires, which allowed it to maneuver with ease through the obstacle course. That's pretty great considering that this stroller is less than half the price of some of the others on this list.

The Details:

  • Dimensions: 35 x 23.8 x 41.1 inches
  • Product weight: 26.71 pounds
  • Child age/weight range: Children up to 45 pounds in each seat

Best for Shopping: Cybex Gazelle S 2 Stroller

CYBEX Gazelle S Stroller, Modular Double Stroller


Why We Like It: It can hold up to three kids (with a ride-on board) and still fit plenty of cargo, while looking great.

But Take Note: The assembly is a real pain.

We've tested both the original Cybex Gazelle S and the 2023 release, the Gazelle S 2, and loved both options for growing families. Like the Uppababy, with the purchase of a second seat (or the cot for newborns) and a kid board, you can push up to three kids without breaking a sweat. Before your family gets that big, however, you can also take advantage of one of our favorite included accessories: a removable shopping basket. Between that basket and the generous cargo space, you can carry up to 55 pounds in addition to your kiddo.

As with just about every other Cybex stroller we've ever tested, assembly was kind of a pain. The back wheels had to be positioned just so to get them to snap in. Then it took two people to figure out how to get the canopy on. There was also a learning curve when it came to folding the stroller. But once we got over all that, we had a really easy time arranging and rearranging the seats—though we didn't quite get to all 20 configurations possible with this stroller. Not yet, anyway! With included adapters, the stroller is also compatible with Cybex, Maxi-Cosi Mico 30, and Nuna Pipa infant car seats (sold separately).

One of the best improvements of the Gazelle S 2 over the original is the harness, which allows you to adjust the strap length with one pull, just like in a car seat. The extra-large canopies shield kids from the elements, while they stay comfortable using the footrest with an extra ledge and a fully reclining seat. Grown-ups will also enjoy the cupholder, which for some reason is a rare sight on high-end strollers lately.

Foam tires and all-wheel suspension made this go quite smoothly over various surfaces, and it handled turns really well, though we didn't think this would be your best stroller for off roading. We really liked the reassurance we got from the fact that the brakes turn from green to red when engaged.

The whole look of this stroller is pretty luxurious, but it also feels like it's built to last, which makes us not too upset about the $800 list price of the Gazelle S 2.

Price at time of publication: $800

The Details:

  • Dimensions: 41.9 x 25.4 x 42.7 inches
  • Product weight: 28.4 pounds (with one seat and no shopping basket)
  • Child age/weight range: Children up to 50 pounds per seat

Best Looking: Nuna Demi Grow Stroller

Nuna DEMI Grow Stroller

Pottery Barn Kids

Why We Like It: It looks great, and comes with very cool extra canopies.

But Take Note: You lose storage with the second seat installed, and it's too cramped for bigger kids.

Nuna's single-to-double stroller looks a bit different from the rest of the pack—the lower seat is very close to the ground, taking up what would normally be your cargo space. It looks odd at first, but the more we thought about it, the more we appreciate that this style values the kids' comfort over the parents' needs. While many other convertible strollers didn't let both seats fully recline, this configuration does. And if that means you can get more stroller naps in, you won't mind lugging your cargo on your shoulders for a bit.

The Demi Grow comes nearly complete and slides right out of the box. The remaining pieces clicked into the designated spots. If you want to convert the stroller to accommodate two children, you’ll have to purchase an extra seat (which also comes in a separate box). 

A three-point harness keeps children buckled in safely, while the stroller’s UPF 50+ extendable or removable canopies have peekaboo mesh windows. The stroller comes with an extra canopy that features additional netting that goes over the entire seat to provide extra protection from the sun and creepy crawlies. Fenders over the foam-filled tires protect kids and adults from mud, water, and other debris.

We put the stroller’s all-wheel suspension to the test on the obstacle course with different terrains, a brisk walk, and trips up and down steps. In these tests it felt light but wobbly, and not very smooth.

Unfortunately, once we got this stroller out into the real world, we realized that the bottom seat is not great for bigger kids. The stroller may be best suited for parents of twins or kids very close to each other in age. We also found that it wasn't fun to fold this stroller, which is surprisingly bulky for something called "Demi," and put in the car.

One other detraction is the price of this stroller. Nuna as a brand tends to get away with high prices like this, but we think your money may be better spent on an Uppababy or something with a bigger seat for kids to grow into.

Price at time of publication: $950

The Details:

  • Dimensions: 24 x 39.5 x 43.5 inches
  • Product weight: 27.4 pounds
  • Child age/weight range: Up to 50 pounds

Best Budget: Graco Modes Nest2Grow Stroller

 Graco Modes Nest2Grow Stroller


Why We Like It: It's super easy to assemble, budget friendly, and comes with snack trays and drink holders for the kids and their grown-ups.

But Take Note: It takes more effort to push on some terrains and feels a little unsturdy when pushing.

If you’re looking for a budget-friendly single-to-double stroller, Graco’s Nest2Grow is a functional option at an affordable price. The Nest2Grow features an inline, or tandem, style, so one seat is located in front of the other.

Assembling this stroller was a piece of cake, since the frame arrived in one piece. Once that was done, we immediately noticed that the frame felt less sturdy than other options on this list. That may be expected for something that costs half as much as those others, too.

With the Nest2Grow, kids can enjoy their favorite treats during their ride with the stroller’s included sturdy snack tray and drink holder. Adults get their own cup holder to stay hydrated along the way, too. We were impressed by the large storage basket under the seats, providing plenty of space for essentials, like an older sibling’s school backpack. The stroller’s leatherette handle is adjustable by simply pushing two buttons to help accommodate parents and caregivers of any size. It stands when folded, and the seat pad is machine-washable.

The Nest2Grow weighs over 30 pounds, a bit on the heavier side, which affected how the stroller performed during the maneuverability test in the lab. The stroller turned easily in the lab on hard floors. When it came to maneuvering on grass and carpet, the Nest2Grow struggled, however. If you plan on using this mostly on pavement and indoors, though, this stroller is a fantastic deal.

Price at time of publication: $390

The Details:

  • Dimensions: 25.75 x 35.5 x 47 inches
  • Product weight: 36 pounds
  • Child age/weight range: Children up to 50 pounds

Best Budget Runner-Up: Evenflo Pivot Xpand Modular Stroller

Evenflo Pivot Xpand Modular Stroller,


Why We Like It: It's a no-frills option with spacious seats.

But Take Note: It's less sturdy on rugged terrain.

Compact with an affordable price tag, the Evenflo Pivot Xpand wasn’t far behind the Nest2Grow when it came to design and maneuverability in our lab tests. Though many features of this stroller are the same as on the Evenflo Gold Pivot Xpand, the price difference in the two aligns with the fact that this one definitely feels less sturdy and less comfortable.

All the pieces of this stroller clicked into place easily without much help needed from instructions. But then we had mixed feelings about the design. The stroller features canopies with peekaboo windows to let parents and caregivers keep an eye on precious cargo, but if you want an extended zip-out canopy, you’ll have to upgrade to the Gold model. To keep kiddos secure and comfortable, the stroller has a five-point harness and a wide seat with padding. It doesn't take too much muscle or thought to switch the seat from forward-facing to parent-facing, and you can use it with an infant car seat or a second toddler seat, purchased separately. Children will appreciate the stroller’s five-position adjustable footrest to stay comfortable while riding. Parents get a cup holder at just the right height for your own drink.

While the Pivot Xpand felt wobbly, it was easier to push than other options on our list. We felt like it was more of a Hyundai than a Cadillac. But if you’ll be using your stroller only on pavement and hard floors, this might not be a problem for your family, and again, you can save your money for other important purchases.

Price at time of publication: $320

The Details:

  • Dimensions: 26.5 x 41.5 x 34 inches
  • Product weight: 28.2 pounds
  • Child age/weight range: 4 to 55 pounds and up to 38 inches tall

Best Side-by-Side: Bugaboo Donkey 5 Twin Black Stroller

Bugaboo Donkey 5 Stroller

Pottery Barn Kids

Why We Like It: Kids can sit side by side, and the stroller keeps their weight steady.

But Take Note: It's wide as a double, so it may be hard to maneuver in a store.

The Bugaboo Donkey 5 isn’t the highest-ranking stroller on our list, largely because of its arduous assembly process and high price, but it offers one thing no others do: side-by-side seating. Bugaboo offers this stroller as a Mono or single stroller, with an interchangeable bassinet and toddler seat, with the option to buy the extension kit to make it a double later. Or, you can buy it all at once as a Twin to get all of that in one shot.

In the lab, we did not enjoy the process of putting the Donkey 5 together. We had to read the directions multiple times and struggled with how to get the (machine-washable) fabric on. Despite that trouble, we came to love the innovative design of the Donkey 5’s extendable base. The stroller features an extra-large canopy with UPF 50+ protection and a mesh peekaboo window. At 29 inches wide, the stroller fits comfortably through most standard doors, but it does take up most of a standard sidewalk. As a single stroller, it's also a great option for anyone who wants to shop with their little one and place things in the handy little side basket.

We weren't thrilled with the Bugaboo in the maneuverability test in the lab. We could feel some resistance when pushing the stroller over bumps on our test and the seat shook a little, though it turned well and the ride was otherwise smooth. Out in the real world, however, we learned that it performs great with a toddler and a baby, distributing their weight quite nicely so the whole thing is easy to push. The deep seats and secure harnesses were a real plus when it came getting kids in and out of this. And then nothing beats the fact that once, we witnessed the toddler holding her sister's hand as they sat next to each other.

Price at time of publication: $1,989

The Details:

  • Dimensions: 29 x 33.5 x 43.7 inches
  • Product weight: 32.8 pounds
  • Child age/weight range: Birth up to 50 pounds, or 48.5 pounds per seat

Our Testing Process 

We tested a total of 17 convertible strollers over the course of the past year, assessing each on several attributes, such as assembly, design, maneuverability, durability, and value. We also spoke with Illinois-based board-certified pediatrician Amanda Stovall, M.D., about safety features, and we reviewed guidance from the American Academy of Pediatrics on how to keep children safe while riding in strollers.

We took time unpacking and assembling strollers right out of the box. We noted whether we needed any extra tools or a second pair of hands during the process. While some strollers simply clicked into place, others desperately required instructions for assembling. Strollers with the easiest assembly, without having to read instructions, scored the highest marks.

For design, we placed sand bags into the strollers to determine the ease or difficulty of buckling in a child with the strollers’ harnesses. We then added the second seat and buckled a second weight bag. We placed a full diaper bag in each stroller to test storage capacity. We also looked at other separate features, like adjustable handlebars, cup holders, footrests, and removable bumper bars. Some of these attributes were more subjective, but we considered features we would want when traveling with our own children, like sun-protection canopies, reliable harnesses, comfort for kids and adults, and style.

We pushed the strollers through an indoor course that had shag carpeting, hardwood flooring, gravel, and a large bump to maneuver over. We also took the strollers on a brisk walk and up and down steps. We checked the brakes on each stroller to determine whether they were easy to use and strategically placed.

Finally, we took our favorites from the lab home to use with our own kids. We periodically check in to re-evaluate our initial lab scores and to see how well these strollers stand up to use in the real world.

Factors to Consider in Convertible Strollers 

Safety Features

Safety is of the utmost importance when it comes to buying products for children. Dr. Stovall first recommends considering your child’s age and development to keep them riding safely. “For young infants who are unable to hold their head up and support their trunks for a given period of time, a reclinable stroller is best. These will lay flat, giving your baby a safe space to travel in while meeting safe sleep standards,” explains Dr. Stovall. “Some convertible strollers allow you to put your own car seat into them, making it easier to maneuver for quick trips. Some strollers have bassinet-type attachments, making them ideal for younger infants.” Not all single-to-double strollers have these options, however, so you’ll want to think about the best fit for your family’s lifestyle. 

One safety feature that’s universal on single-to-double strollers is a harness. They often come in three- or five-point restraints, but Dr. Stovall recommends using a five-point harness if possible. “Check the straps—just like in car seats, five-point harnesses are safest,” she says. “If you are trying to use straps for a younger baby, ensure they cannot slip through the leg openings.” Moreover, Dr. Stovall says that parents and caregivers should check the weight limit. “Strollers are safest and most stable when the rider does not exceed the weight limit,” she says. 

Finally, don’t forget to check the brakes, Dr. Stovall says. “The safest strollers have two brakes on the back wheels, are easy for you to use, and are out of reach of children in the stroller,” she explains.


Look at the stroller’s size, weight, and overall design to ensure that it will fit into your family’s lifestyle. For example, families who travel often likely won’t want a heavy stroller that is difficult to fit in the trunk of a vehicle or overhead bin. Bells and whistles are nice, but they often come with more than just a high price tag. “The more attachments and gadgets the stroller has, the more likely that it will be bulkier and more difficult to fit in the trunk of smaller vehicles,” Dr. Stovall tells us, adding that “wide-based strollers are more stable and, overall, less likely to tip over.” 

Be sure to check the size of the storage basket to ensure that toys, snacks, and other important items will fit, and that the items won’t hinder the stroller's operation.

Ease of Use

During the maneuverability test in the Lab, some strollers we tested struggled with certain terrains or sharp turns. Depending on where your family plans to use the stroller, these issues might not be a big problem. Down the road, however, you may find yourself wishing you had gone with a different stroller. Look for a stroller that maneuvers with ease so it will be less stressful during outings. 


Not only should children be comfortable while riding, but parents and caregivers deserve a stroller that’s functional and easy to use comfortably as well. For the kiddos, look for canopies to help protect sensitive eyes and skin from the sun. “Be mindful of the sun, even on cooler days. Most strollers have a canopy, and some have a clear window so you can keep an eye on your child from behind,” Dr. Stovall says. Also check to see whether the stroller has recline options, as many single-to-double strollers do not, due to a lack of space. This small feature can make a huge difference to little ones who are desperate for a nap while out and about. 

An adjustable handlebar allows parents and caregivers of any height to push the stroller comfortably. Some convertible strollers feature handlebars with an adjustable angle, and others with an adjustable length. It’s up to you which you’d prefer.

Your Questions, Answered

Are single-to-double strollers worth it?

Because these strollers adapt with your growing family, you typically only have to purchase one stroller, giving you the most bang for your buck. While single-to-double strollers aren’t a requirement for those who have multiple children, they are very handy.

Can you convert a single stroller to a double stroller?

Not every single stroller can convert to a double stroller unless the manufacturer states that it can. This is why it’s important to consider your family’s lifestyle and future needs. Single strollers are designed to hold one child, while double strollers can support the weight of two children. Attempting to place two children into what’s supposed to be a single stroller puts children's safety at risk.

What do single-to-double convertible strollers cost?

Strollers that can convert from a single to a double are often a pricier investment. You will likely buy the convertible stroller with a single seat, which can cost between $320-$1,400. Then, depending on the brand, you may also need to buy the second seat and any adapters to convert the stroller from a single to a double—this additional cost starts around $100. Our best overall, the Uppababy Vista V2, is definitely on the more expensive side at $1,000 (for the frame, first seat, and the bassinet), but we think it is well worth the cost if you plan to use it with multiple children as your family grows.
