Stroller shopping often involves trying to reconcile two conflicting goals: You want a stroller that's sturdy enough to hold two kids as your family grows, yet compact enough for stress-free lifting into your trunk.

The Agio Z4 and UPPAbaby VISTA are among the only strollers that meet both requirements. They're two of the lightest strollers that convert to a double, weighing in at 22.5 pounds and 27 pounds, respectively.

You're probably more familiar with the UPPAbaby VISTA, a top-seller revered for its versatility and style for more than a decade.

The Agio Z4 is a newcomer that debuted in 2019 and gained a second seat option in 2020. But its manufacturer isn't new to the stroller game: Agio is a specialty brand of Peg-Perego, an Italian maker of baby gear since 1949.

In this post, we'll help you determine which stroller is better for your family: the Agio Z4 by Peg-Perego or the UPPAbaby VISTA.

Agio Z4 vs. UPPAbaby VISTA Stroller Comparison

Agio Z4 vs. UPPAbaby VISTA V2 Video Comparison

See below for a video comparing the Agio Z4 and UPPAbaby VISTA V2, including a review of single and double configurations, folding, specifications, compatible car seats, colors and materials, and more.

Agio Z4 by Peg-Perego

The Agio Z4 is among the lightest and most affordable convertible strollers on the market. Just add a set of adapters to the Z4's 22-pound frame, and your stroller instantly becomes a double when you add an infant car seat or bassinet for your newborn.

All-wheel suspension, a standing fold and a height-adjustable canopy are among the features that make the Z4 easy to use and maneuver.

Made in Italy by Peg-Perego, the Agio Z4 is sold exclusively by specialty retailers like Strolleria. All Agio products offer premium materials and a 5-year warranty, the longest in the industry.

The Z4 also has an almost-identical twin, the Peg-Perego YPSI. The YPSI offers the same functionality as the Z4 but differs in a few ways: It has less-premium fabrics with a shorter warranty, and most colors are packaged only as a travel system. See this Agio Z4 vs. Peg-Perego YPSI comparison for more details.

Agio introduced a second seat for the Z4 in 2020, although the stroller itself did not change. Meet the Agio Z4 in the video below.


The UPPAbaby VISTA is a top choice for quality and ease of use, between its three-year warranty and features like a standing fold, oversized storage basket, and one-click compatibility with the UPPAbaby MESA car seat.

The VISTA includes an overnight-approved bassinet with purchase and easily converts to a double stroller when you add the lower RumbleSeat (as well as upper and lower adapters for some configurations.)

UPPAbaby debuted the VISTA V2 in 2020, adding upgrades like enhanced all-wheel suspension for a smoother ride, a redesigned sun canopy with extra ventilation, and a no-rethread harness for easy adjustments. See the VISTA V2 in the video below.

Agio Z4 vs. UPPAbaby VISTA Single Stroller Price

The Agio Z4 is one of the most affordable strollers that converts from single to double, priced more than $300 lower than the UPPAbaby VISTA V2.

However, the VISTA includes several accessories sold separately for the Z4, like a bassinet along with rain and bug covers. If you add the same accessories for the Z4, the stroller is evenly priced with the VISTA.

The purchase of an Agio Z4 stroller includes:

  • Single stroller with one seat
  • Car seat adapters for Peg-Perego infant car seats manufactured in January 2018 or later

The purchase of an UPPAbaby VISTA includes:

  • Single stroller with Toddler Seat
  • Bassinet
  • Bassinet storage bag
  • Rain cover for Toddler Seat
  • Bug cover for Toddler Seat and bassinet

Here's what the pricing for each single stroller looks like when you compare the strollers with identical items.

Agio Z4

  • Stroller: $599.99
  • Bassinet: $249.99
  • Bug cover: $39.99
  • Rain cover: $39.99
  • Total price for stroller and bassinet: $849.98
  • Total price for equivalent items to VISTA: $929.96


  • Stroller, bassinet and rain/bug covers: $929.99 to $969.99

Agio Z4 vs. UPPAbaby VISTA Stroller Comparison

Agio Z4 vs. UPPAbaby VISTA Double Stroller Price

As a double stroller, the Agio Z4 can be far less expensive than the UPPAbaby VISTA, depending on the configurations you plan to use.

All components considered, the Z4 double stroller costs about $185 less than the VISTA V2 double.

But the Z4 could save you more than $500 if you plan to start using the stroller as many families do—with a car seat in the upper position and your toddler in the lower seat. It costs only $59.99 to convert the Z4 from single to double by adding a set of double adapters.

The Z4 stroller seats are identical, allowing you to simply relocate the seat that came with your stroller from the upper position to the lower position. By adding an infant car seat or bassinet on top, you can prolong—or even forgo—the purchase of the lower Companion Seat.

The upper and lower seats on the UPPAbaby VISTA aren't the same size, so they aren't interchangeable. To use an infant car seat on the upper position of the VISTA, parents must purchase the lower RumbleSeat. Upper and lower adapters, sold separately, are also needed for most double configurations. See What Adapters Do I Need for the UPPAbaby VISTA? for more details.

Agio Z4 double stroller price

  • Stroller: $599.99
  • Bassinet: $249.99
  • Companion Seat: $249.99
  • Total price with one stroller seat, double adapters and infant car seat: $659.98 (plus car seat)
  • Total price with two stroller seats and double adapters: $989.97

UPPAbaby VISTA V2 double stroller price

  • Stroller and bassinet: $929.99 and up
  • Second seat (RumbleSeat): $199.99
  • Upper adapters: $19.99
  • Lower adapters: $24.99
  • Total price with two stroller seats and upper/lower adapters: $1,174.96 to $1,214.96

Agio Z4 vs. UPPAbaby VISTA Stroller Comparison

Agio Z4 vs. UPPAbaby VISTA Weight and Dimensions

The Agio Z4 is the lightest stroller on the market that converts from single to double, weighing 4.5 pounds less than the VISTA V2 as a single. It's also more than 5 inches more narrow, helping to navigate tight spaces.

When configured as a double stroller with two seats, the Agio Z4 is similar in weight to the VISTA V2 because of the addition of the double adapters, which are needed for all double configurations.

Single stroller weight

  • Agio Z4: 22.5 pounds
  • VISTA V2: 27 pounds

Double stroller weight

  • Agio Z4: 31.5 pounds
  • VISTA V2: 32.6 pounds

    Single stroller dimensions

    • Agio Z4: 39.25"L x 20"W x 40.25"H
    • VISTA V2: 36"L x 25.7"W x 39.5"H

    Single stroller folded dimensions

    • Agio Z4: 15.25"L x 20"W x 32.25"H
    • VISTA V2: 17.3"L x 25.7"W x 33"H

    Agio Z4 vs. UPPAbaby VISTA Stroller Comparison

      Agio Z4 vs. UPPAbaby VISTA Weight Limit

      Featuring two identical seats that each accommodate a child up to 50 pounds, the Agio Z4 has a higher overall weight capacity than the UPPAbaby VISTA.

      That's because the seats of the VISTA are not identical, with the Toddler Seat (the upper stroller seat) holding 50 pounds and the RumbleSeat (the lower seat) accommodating 35 pounds.

      The RumbleSeat can be a drawback for parents with older children who have exceeded the weight limit, as larger toddlers would need to sit in the upper position with the baby farther away from the parent in the lower position. Most kids reach 35 pounds around age 3, but some toddlers may become too tall for the RumbleSeat first.

      Weight capacity 

      • Agio Z4: 50 pounds per seat
      • VISTA V2: 50 pounds for upper Toddler Seat; 35 pounds for lower RumbleSeat

      Agio Z4 vs. UPPAbaby VISTA Warranty

      Both the Agio Z4 and UPPAbaby VISTA V2 have the longest stroller warranties on the market—an important factor to consider when investing in a stroller to last through multiple kids. But all Agio products carry a 5-year warranty, two years longer than UPPAbaby's warranty on the VISTA.

      • Agio Z4: 5 years
      • VISTA V2: 3 years

      Agio Z4 vs. UPPAbaby VISTA Double Stroller Configurations 

      Both the Agio Z4 and UPPAbaby VISTA offer more than a dozen configurations for siblings and twins.

      Both upper and lower seats are reversible, allowing the child to face you or face forward. To accommodate a newborn and a toddler, both strollers can be used with a car seat or bassinet in double mode. And for twins, both take two infant car seats and two bassinets.

      Double Adapters

      Adapters are needed to convert either stroller from single to double. While UPPAbaby sells separate upper adapters and lower adapters, the Agio adapters are packaged together as a set of double adapters.

      The Agio Z4 double adapters—both upper and lower—are needed at all times in double mode, regardless of the configuration. The upper adapters can only be attached and removed when the stroller is folded, while the lower adapters snap onto the frame. 

      Most families using the VISTA as a double will purchase the upper adapters: They're needed to attach a car seat to the upper position, and they're recommended (though not required) to add spacing between the two stroller seats. You'll need the lower adapters only if you're attaching a car seat or bassinet to the lower position of the stroller. See What Adapters Do I Need for the UPPAbaby VISTA? for more details.

      Both strollers fold with upper and lower adapters attached.

      Configuration Differences

      Here are the differences between the Agio Z4 and UPPAbaby VISTA configurations.

      • A set of double adapters are needed for all Agio Z4 configurations. No adapters are required for using the Toddler Seat and RumbleSeat on the VISTA, although the upper adapter is still recommended to add leg room between the seats.
      • The main seat on the Agio Z4 is the identical to the Companion Seat, allowing it to be moved from the upper or lower position. The lower RumbleSeat on the VISTA is a smaller replica of the upper Toddler Seat, so the two aren't interchangeable.
      • The Agio Z4 bassinet can be used in the upper position with the stroller seat in the lower position. On the VISTA, the bassinet only fits on the lower position when the stroller is used as a double.

      UPPAbaby VISTA Configurations

      Agio Z4 vs. UPPAbaby VISTA Bassinet

      A bassinet is the coziest way for your baby to begin strolling: It allows your infant to lie flat, which is safest for her head and neck, and provides more airflow than a car seat.

      Both the Agio Z4 and UPPAbaby VISTA have bassinet options that can be used on the stroller in either single or double mode, as well as on a bassinet stand for overnight sleeping in your home.

      Your purchase of the UPPAbaby VISTA includes a bassinet, which includes a zippered ventilation panel on the back, as well as a pull-out sunshade for complete sun coverage. The bassinet clicks into the wooden UPPAbaby bassinet stand, which can later be used as a laundry hamper.

      The Agio Z4 bassinet, sold separately, includes ventilation inserts, a window and an extended apron that provides protection from the elements. Add the Agio bassinet stand to bring baby to your bedside, keeping essentials in a basket underneath.

      Bassinet Prices

      • Agio Z4 bassinet: $249.99
      • Agio Z4 bassinet stand: $149.99
      • VISTA bassinet: included with stroller
      • VISTA bassinet stand: $149.99

      Agio Z4 vs. UPPAbaby VISTA How to Fold

      Both the Agio Z4 and UPPAbaby VISTA stand when folded, making the strollers easy to lift into the car.

      As single strollers, the two models are about the same size when folded. But when configured as a double, the Z4 is about a foot taller than the VISTA because of the height of the double adapters. 

      You can save space by removing the Z4 seat before folding the stroller, then removing the upper adapters (which can only be detached when the stroller is folded). The VISTA folds more compactly with adapters attached.

      For both strollers (and most doubles), you'll need to remove the lower seat before folding.

      See the photos below for a look at each fold: On the left, the strollers are pictured in single mode. On the right, the Z4 is folded with the double adapters, and the VISTA is folded with the upper adapter attached.

      With the purchase of car seat adapters, both strollers are also compatible with car seats from several other leading brands.
