When you're shopping for your first stroller, you're naturally thinking about your first baby—not necessarily your second. Then, in seemingly no time, Baby #2 is on the way, but Baby #1 still needs the stroller, too. Now what?

Many families purchase a double stroller with side-by-side seats, which works well for a period of time. But when the older child graduates from stroller travel, you’re either back to where you started with the single stroller, or you’re pushing a double stroller with only one kid in it (resulting in unnecessary bulkiness, uneven weight distribution—and a couple of weird looks).

The solution? A convertible stroller—one that can be both a single and a double.  A convertible stroller allows you to attach a second stroller seat, infant car seat or, in some cases, a bassinet in order to transform a single stroller into a ride for two.

When your older child insists she’s too grown-up for a stroller, you can detach the second seat to convert it back to a single stroller. And when it turns out that she’s not quite grown-up enough for long walks, after all, you can add a glider board so she can ride along.

Another pro: Most convertible strollers offer multiple seat configurations so that your kids can face you, face the world or face each other, helping you attempt to keep two kids happy at the same time.

The cons: Given their size and complexity, convertible strollers can be both heavy and expensive. But because it endures for years as your family expands, a high-quality convertible stroller can be a wise investment for new parents.

Here’s a look at a dozen high-quality convertible strollers that grow with your family (listed by ascending price):

Baby Jogger City Select

The versatile Baby Jogger City Select was one of the first convertible strollers on the market—and remains one of the most popular, too.

The City Select is one of the more affordable convertible strollers available.

Baby Jogger updated the look of the City Select in 2019 to reflect more modern, neutral colors and more premium fabrics. No changes were made for 2020.

Agio Z4 by Peg-Perego and Peg-Perego YPSI

The Agio Z4 and Peg-Perego YPSI—two models that are nearly-identical twins—became the lightest convertible strollers on the market in 2020. They weigh just 22.5 pounds, making them lighter than many single strollers, yet they're sturdy enough to accommodate a total weight of 100 pounds.

Both models are made in Italy by Peg-Perego with the same features, functionality and configurations. The Agio brand, sold exclusively at specialty retailers like Strolleria, has a longer warranty, more premium fabrics and more travel system options. See this Agio Z4 vs. Peg-Perego YPSI comparison for more details.

If you're using a car seat or bassinet for your newborn, it only takes a set of double adapters ($59.99) to change the stroller to double mode. Because both stroller seats are identical, offering a 50-pound weight limit, you can simply move the upper seat to the lower position.

Agio Z4 Price

• Single stroller: $599.99
• Double stroller: $909.97 (includes companion seat and double adapters)

Peg-Perego YPSI Price

• Single stroller: $599.99 (Mon Amour color only; Onyx and Atmosphere colors sold only as travel system for $799.99)

How to fold Agio Z4 and Peg-Perego YPSI

The Agio Z4 and Peg-Perego YPSI have an easy two-step fold: First, pull up on the triggers to fold the seat in half. Then pull a bar underneath the seat, and the handlebar swings over the stroller into a standing position.

When using the stroller as a double, you'll need to remove the lower seat before folding. The double adapters add several inches to the height of the stroller when folded. You can save space by removing the upper seat before folding the stroller, then removing the upper adapters (which can only be detached when the stroller is folded).

Agio Z4 and Peg-Perego YPSI Drawbacks

• Requires double adapters (on both upper and lower positions) for all double configurations
• Stroller has to be folded in order to attach and remove upper adapters
• Stroller is tall when folded as a double due to height of double adapters
• Lacks accessories such as cup holder and snack tray
• YPSI can only be purchased as a travel system for Onyx Black and Atmosphere Grey colors

Baby Jogger City Select LUX

The Baby Jogger City Select LUX builds on the popularity of the original City Select, adding improved maneuverability, more premium details and additional accessory options.

For an additional $90, the City Select LUX offers all-wheel suspension for a smoother ride, a decelerating hand brake, upgraded fabrics, and a fold that's 30 percent smaller fold than the original Select thanks to folding seats. The bench seat, an accessory that only fits the City Select LUX, seats kids up to 65 pounds, extending the life of the stroller for older kids.

See all the differences between the two City Select versions in this Baby Jogger City Select vs. City Select LUX comparison.

City Select LUX Fold

Like the City Select, the City Select LUX folds when you pull up on the triggers on each side of the stroller. But unlike the original, the seat itself on the City Select LUX also folds in half, creating a more compact fold.

The City Select LUX folds with the seat facing either direction. To fold the stroller when configured as a double, first remove the second seat and second seat adapter posts.

Vidiamo Limo

New in 2020, the French-designed Vidiamo Limo is the only stroller that converts from single to double with no extra parts or purchases required. The frame of the Limo is expandable, allowing a foldaway seat to slide out from underneath the primary seat.

That makes the stroller ideal for families with an infant and a toddler who insists on walking—until that mid-zoo tantrum that makes you wish you had a double stroller. While the foldaway seat is in use, the primary seat can be reclined flat for a newborn or paired with a car seat or bassinet.

At 25 pounds, the Vidiamo Limo is an average weight for a single stroller but can fit two kids up to 40 pounds. With both seats included in the $699 price, the Limo is also one of the most affordable convertible options.

How to fold Vidiamo Limo

The Vidiamo Limo folds in one step, with one hand, when you press a button on the back of the frame and pull up. The stroller stands when folded and can also be trolleyed like a suitcase.

Vidiamo Limo Benefits

• Instantly transforms from single to double without having to buy or attach a second seat

• Foldaway seat has limited function and does not recline
• Stroller is not very compact when folded, although similar to other double strollers
• Stroller canopy and seat fabrics must be removed to attach car seat

Cybex Gazelle S

The Gazelle S debuted in 2020 as the first convertible stroller from Cybex, the German manufacturer known for its innovative and stylish line of baby gear.

Among the stroller's more than 20 configurations are a few options that set the Gazelle apart. The Gazelle includes a shopping basket that can be used in the stroller's upper position (with your child in the lower seat)—a configuration that nearly doubles the storage capacity of the stroller.

When your family grows, you may not need to buy a second seat. The seat that comes with the Gazelle can be moved to the lower position, allowing you to use an infant car seat or bassinet on top for your newborn. Adapters that convert the Gazelle from single to double are incorporated into the stroller frame, so you won't need to purchase additional accessories.

• Single stroller: $699.95

Then press the button underneath the handle while sliding the button on top of the handle. Use your left hand to press the trigger on the side of the frame while retracting the handlebar.

Pull the handlebar down and toward you, and push the spoke into the lock. The Gazelle stands when folded and can be lifted using the handle built-into the seat plastic.

Nuna Demi Grow

The Demi Grow launched in 2018 as the first convertible stroller from Nuna, the stylish Dutch brand known for its strollers and ultra-popular Nuna PIPA line of infant car seats.

Unlike other convertible strollers in which one seat sits in front of the other, the two seats on the Demi Grow are stacked. With the weight of both kids on the rear axle, the stroller becomes easier to maneuver and can accommodate a higher weight capacity of 50 pounds per seat.

The stroller seats are identical, which allows the upper seat to be moved to the lower seat when a sibling comes along. Included with purchase are two sets of Nuna car seat adapters, including a ring-shaped adapter that allows the car seat to be attached and removed using only one hand.

Nuna Demi Grow Price

• Single price: $799.95

How to fold Nuna Demi Grow

You'll need to remove the lower seat before folding the stroller when configured as a double.

UPPAbaby VISTA V2

The UPPAbaby VISTA has been a trendsetting stroller for more than a decade. The VISTA is one of the most popular models on the market, thanks to its ease of use, versatility and classy yet practical style.

The VISTA offers a simple, standing fold and includes a bassinet that's safe for overnight sleeping, a height-adjustable sun canopy and perhaps the largest storage basket you'll find on any stroller.

When your family grows, attach the RumbleSeat to the lower position to create a double, and use upper and lower adapters to create more than a dozen configurations involving up to two reversible stroller seats, car seats and bassinets. The Toddler Seat for the upper position has a 50-pound weight limit, while the smaller RumbleSeat holds 35 pounds in the lower position only.
