Agio Z4 vs. Peg Perego YPSI Stroller Comparison

Note: Strolleria no longer carries the AgioZ4, but functionally, the Agio Z4 and Peg Perego YPSI strollers are identical!

Both models are 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.

While the Agio Z4 is exclusive to select stores and includes a longer warranty, both the Z4 and YPSI are made with premium materials and offer flexibility with configurations and car seat compatibility. Peg Perego also makes the YPSI in a wider range of colors, 

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


Peg Perego's lightest weight, full-featured stroller, the ultra-narrow YPSI converts from a single to a double and offers many configurations with one, two, or even three children. Aesthetically, it offers black or rose gold leatherette instead of the Agio's brown or grey leatherette, as well as a more diverse color selection ranging from neutral to colorful options.

The YPSI stroller is manufactured in Italy by Peg Perego—a manufacturer of high-quality baby products since 1949including a 2 year warranty and wide range of accessories.


Also made in Italy by Peg Perego, the Agio Z4 stroller is exclusive to select independent retailers. The Agio collection features brown leatherette details and an industry-leading 5-year warranty.

The Z4 can be paired with a matching Agio Primo Viaggio 4-35 Nido or Agio Primo Viaggio 4-35 Lounge infant car seat. Parents can also use adapters to attach a car seat from Nuna, Cybex, Maxi-Cosi or Clek for a more customized travel system.

Agio Z4 vs. Peg Perego YPSI Features

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 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 Warranty

Apart from color options, 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 includes a longer 5-year warranty.

Manufacturer's warranty covers any factory 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), an additional three years could make a difference in the longevity of your stroller.

However, it is more common for a defect to arise right out of the box, such as stitching imperfections in the fabrics, rather than develop over time. Warranties do not cover travel damage, damage due to misuse, and other situations determined by the manufacturer.
