At first glance, the Agio Z4 and Peg-Perego YPSI strollers appear identical—and they nearly are!

Functionally, the Z4 and YPSI are the same: They're made in Italy by the same parent company, Peg-Perego, and offer the same features, like a lightweight, standing fold and the ability to convert to a double stroller.

But the Agio Z4, which is exclusive to specialty stores like Strolleria, includes some key differences, like a longer warranty, more premium fabrics, and more customizable travel system options.

In this comparison, we'll help you determine which of these similar strollers will be best for your family.


Made in Italy by Peg-Perego—a manufacturer of high-quality baby products since 1949—the Agio Z4 stroller is exclusive to independent retailers like Strolleria. The Agio collection features premium fabrics, brown leatherette details and an industry-leading 5-year warranty.

The Z4 can be paired with a matching Agio Primo Viaggio 4-35 Nido infant car seat. But because the stroller and car seat are packaged separately, parents can also use adapters to attach a car seat from Nuna, Cybex, Maxi-Cosi or Clek for a more customized travel system.


Functionally, the Peg-Perego YPSI is the same as the Agio Z4, although it has a shorter warranty (2 years vs. 5 years).

Aesthetically, it looks a bit different: It has black leatherette instead of brown, and the fabrics aren't as soft or textured.

If you're buying the YPSI in the Onyx Black or Atmosphere Grey colors, you'll automatically be purchasing a Peg-Perego Primo Viaggio 4-35 Nido car seat in the same color—the two products are packaged together in a single box. Only the Mon Amour color of the YPSI stroller is sold separately.


Functionally, the Z4 and YPSI strollers are the identical, and both have the ability to expand to a double stroller.

Both feature a lightweight, narrow frame (that's only 20" wide!) with durable, all-terrain tires, a removable and reversible toddler seat, the option to attach an infant car seat or bassinet. and the ability to expand from a single to a double stroller for two!

The toddler seat on both models can be removed and reversed to face parents or face forward, and it features a large, expandable canopy with UPF 50+ sun protection. For smaller kids, the integrated pop-out footrest can be raised to provide more support and lowered as they get older. The seat folds compactly with the rest of the stroller frame, which can stand on its own when folded.

Using the Z4/YPSI double adapters, you can turn any Z4 or YPSI stroller into a double. This set of upper and lower adapter pieces allow you to add a Companion Seat, sold separately, or an infant car seat or bassinet.

One set of car seat adapters for Peg-Perego infant car seats (called "links") are included with your stroller purchase. The links fit Primo Viaggio 4-35 and Nido car seats manufactured in January 2018 or later; older car seats aren't compatible.

Both strollers can also be used for twins. You can purchase a second set of Primo Viaggio links for twins, or purchase adapters to attach an infant car seat from select other brands. See here for a list of infant car seats compatible with the Agio Z4 and Peg-Perego YPSI strollers.

The YPSI and Z4 are also compatible with the same accessories, including a wheeled travel bag, bassinet stand, baby stage pad for the toddler seat, and a ride-along board for an older toddler. For taller parents, extend the handlebar an additional 5.75 inches with the handle extensions.


Agio Z4 vs. Peg-Perego YPSI Stroller Comparison

Choose from three sophisticated fashions for the Z4: Agio Grey, Agio Black, and Agio Mirage, which feature premium fabrics on the seat and canopy as well as eco-leather details on the handlebar, bumper bar, and piping. Grey and Black include saddle brown eco-leather, while Mirage has black eco-leather with silver metal accents. 

While the Agio Primo Viaggio 4-35 Nido car seat is available in the same three colors, the stroller and car seats are packaged separately to allow more flexibility.

For the Peg-Perego YPSI, only one color of the stroller is packaged separately from the stroller: Mon Amour.

The Onyx Black and Atmosphere Grey colors cannot be purchased without an infant car seat, as they're packaged in the same box as the matching Primo Viaggio 4-35 Nido infant car seat as a travel system. 

Mon Amour is the most similar to the Agio collection, featuring more premium fabrics on the canopy and seat, along with a chic rose gold frame and leatherette details.

All three colors of the YPSI come with eco leather handlebar and bumper bar for a sleek, modern look and comfortable grip.

Agio z4 vs peg-perego YPSI stroller comparison


Apart from packaging and fabric choices, perhaps the biggest difference between the Peg-Perego YPSI and Agio Z4 is the warranty.

Peg-Perego includes a 2-year manufacturer's warranty with the YPSI stroller, but the Agio collection is covered under an industry-leading 5-year warranty.

Manufacturer's warranty covers any defect during that period starting from the date of purchase, so you will have three additional years of warranty coverage on the Z4 compared to the YPSI.

With a stroller that can grow with your family to accommodate baby #2, or even #3 (by adding the ride-along toddler board accessory), those additional three years could make a difference in the longevity of your stroller.

Agio Z4 vs. Peg-Perego YPSI Price

Peg-Perego packages the Onyx and Atmosphere YPSI in one box with the infant car seat at a slightly lower price, so you will spend $150-$200 less if purchasing either of these YPSI travel systems, compared to the Z4 travel system or the YPSI travel system in Mon Amour.
