Agio Z4 Stroller by Peg-Perego

Compatibility Guide


The Agio Z4 stroller combines sophisticated Italian style with easy-to-use features for an everyday stroller ideal for urban and suburban families alike.

The Agio Z4 now grows with your family when you add a companion seat and double adapters to convert the stroller from single to double. The Z4 is one of the lightest convertible strollers on the market, as well as one of few that hold an even 50-pound weight limit on each seat.

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.

With a width of 20 inches, the Z4 is as narrow as an umbrella stroller, making it easy to navigate through city sidewalks and store aisles. But while compact, the Z4 is also sturdy, with all-wheel suspension that helps you navigate any terrain. The Z4 folds with one hand and stands when folded, making it easy to get in and out of the car.

Use the Z4 from birth by attaching an infant car seat or overnight-approved bassinet (sold separately). With a reversible seat, pop-out footrest and height-adjustable canopy, the stroller will last as long as you need it.

    Love the design

    I wish the material was a water prof or to come with rain cover I live in Seattle it gets pretty saggy here

    Best Double Stroller we found.

    We have a 2 year old and are preparing for a new infant.

    We had the Citi Mini GT single stroller and love it. We were looking for something that'd be as easy to fold and rugged for walks on unpaved paths.

    After some research we got the Citi Mini GT Double. It looked like a simple fold. But once we got it, we realized that it was a BEAST. Heavy, Wide, and generally too bulky. We determined that if the Citi Mini GT Double was too wide, then all of the side-by-side strollers were too wide for us.

    We looked at the tandem (front-back) strollers... but they looked really annoying to set up and break down every time you want to put them in the car. A bunch of pieces and adapters. The seats are removable... but where are you going to put them? The whole thing seemed like a pain. Also some of the strollers have major differences between the front and back seats. Either the kid in back can't see anything, or the kid in front can't recline... generally, not idea.

    We even tried adding a "buggy-board" (ride along foot board) to the back of our existing stroller... but it really messed up the ride and feel of the stroller. It ruined the one thing we loved about our Citi Mini GT.

    After we found the Z4... I feel like we found the perfect stroller for us. We have a peg perego 4/35 car seat - so we don't need any crazy adapters and bars that get in the way. The kid in front and back both have a view. Both could eventually recline. It's light! You can actually remove one of the seats when you want to add the stroller so you're not adding the car seat to the stroller on top of the regular seat... you can remove the regular seat saving some bulk / weight. It looks well built. It really does look like the Uppa Baby. I've confused the UB with the Z4 several times while out in public. Nice materials. When it arrived our toddler was excited to sit in it and ride around. "So comfy, so soft" is what our toddler said.

    Pretty easy to fold.
    Pretty light (for what it is)
    Great with a peg perego car seat.
    Lots of room in the bottom, especially compared to the citi mini gt.

    The Z4 is EXACTLY the same stroller as the Peg Perego YPSI. I didn't know this until after I purchased the Z4. I think they're basically identical except for the warranty, branding, and slightly different fabrics.

    The one downside is cup holders. If you buy the Peg Perego cup holder, it attaches on the OUTSIDE of the stroller, making the stroller wider. We bought a "stroller organizer" that velcros to the handlebars... but that doesn't work with this stroller and a car seat. The car seat fills up the entire handle-bar area and there's no room for a organizer/cupholder. That's something we'll need to solve for.

    Better than all the competition

    I went back and forth for a few years about whether to spend the money on a nice set like this, and what brand was truly the best. I skimped with my first child and it created so many postural issues that we spent so much money on accessories trying to fix. Then we bought more of that brand to fit certain needs for sake of compatibility. Now I went online and searched for months with kiddo #2 to find the best system at this price point. This still has more options and configurations than the more commonly trendy name brands at this cost... I couldn’t resist giving it a try. So glad I did I couldn’t be happier. Hoping if we have a third he/she can enjoy sharing this stroller as well as it fits two kids for 15lb longer than the competition. Best kiddo purchase yet.

    The best hidden secret

    The Agio Z4 is amazing !! I have a 3 year old and we are expecting our second in 2 months. My daughter still naps once in a while and gets tired when on long walks or zoo trips. I definitely did not want to spend a lot of money on a double stroller. With this stroller, a pair of adapters is all you need to convert an amazing single stroller to a double stroller. We plan on using a car seat of the new baby and the seat in the lower position for our older child. We also got the piggyback board.
    This stroller is small, light weight, and very compact as a single stroller. The suspension is amazing and the basket is Extra-Large.

    Agio Z4

    I had not heard of this brand until Strolleria recommended it. Peg Perego has been around for a long time, but Agio is new. We were deciding between this and the Nuna Mixx. Ultimately we decided on the Z4 because it was lighter and easier to lift because it stands when you fold it. We are still able to use our Nuna car seat with it, too.
