Peg Perego Viaggio Flex Booster Seat Review (US/Canada)
In this review, we’ll take a close look at why the Peg Perego Viaggio Flex booster may be a good option for your booster-aged child. This booster can be an excellent option if you need to fit 3 kids across the back of your vehicle. It’s also a nice option for parents who travel often since it folds up. Additionally, if you have non-removable headrests in your vehicle, this is one of the high-back booster options that will work.

✅ Seat is Good for You If:
✅ You frequently use Lyft/Uber/Taxis.
This seat works well in most vehicles. It folds up to make it easier to carry around as well. For carrying it around the city, you may want to grab the separate travel bag that Peg Perego makes for this seat.
✅ You travel often.
This seat folds up to the size of a carry-on so it can be stowed in the overhead compartment of many planes. This makes it a good option for parents who want to take a high back booster on their family trips. And at 15 pounds, it’s not overly heavy to carry around.
✅ You need to fit 3 across in a vehicle.
The Peg Perego Viaggio Flex is 17″ wide unless you choose to use the backrest in the optional wider positions. At the lap belt path, it’s closer to 14″, so it’s usually very easy for a child to buckle the seat belt even when it’s next to another car seat. In this picture, we have it in a 3 across configuration with a Safety 1st SlimRide (review) and a Graco SnugRide SnugLock 35 DLX (review). For other narrow car seat options that might work well next to this one, check out our blog post on fitting 3 across here.
✅ Your vehicle has non-removable headrests.
This booster is one of the few options that works well with non-removable headrests because it does not have to be flush with the vehicle seat. Other options that work with these kinds of headrests are Nuna Aace, Clek Oobr, and any of the Diono or Evenflo high-back boosters.
✅You have a tall child.
This high back booster has 63″ limits, which is currently the maximum standing height limit available for boosters. It also has a very tall belt guide that can accommodate a child until their torso height is around 22″.
🚩 Use Caution If:
🚩You want a booster that converts to backless as well.
This is a high back booster only. But it has a very tall headrest, so it will accommodate most children until they can fit properly in the seat belt.
🚩You want a lightweight option to move between different vehicles.
This booster weighs about 15 pounds. With some boosters as light as 5 pounds, this is quite a heavy one. But it’s still not as heavy as many convertible car seats are, so 15 pounds may be ok for you!
️ Stand Out Features:
It folds!
We love that this booster can fold. This also makes it easy for parents who want to have an extra booster in their trunk for carpooling or for parents who travel often. It makes storing it in your house easier as well!
It has rigid lower anchors
Lower anchors on the booster are optional. But if you don’t use the lower anchors, then you need to buckle the seat belt whenever the child is not riding in the vehicle with you. The lower anchors on this seat are rigid, which also makes them easy to attach in many vehicles.
It has many adjustments for child fit
This high back booster has a couple of adjustment options to improve the child’s comfort. In addition, it has a recline option that can be good for tired kids. There is also a knob on the back of the seat that allows you to widen the seat where the side wings are. The width of the booster is 17-20″ depending on how you have this set.
⚠️ Quirks to Be Aware Of:
⚠️ Check the lap belt fit
In a few vehicles, we have found that the lap belt is too low. If you find this to be the case, you can try a different seating position. If this does not remedy the situation, you will need a different high-back booster. The lap belt should be on the hips.
✈️ Airplane Use
Like all boosters, the Peg Perego Viaggio Flex does NOT have aircraft approval. But because it folds up, this is still a great option for airplane travel. When folded, it’s small enough to take as carry-on luggage for most airlines. For help with all things airplane travel and car seats, check out our Wheels Up Course and private Facebook group.
SITS Bottom Line
The Peg Perego Viaggio Flex high-back booster seat is designed for versatility, accommodating various travel and vehicle needs. In addition, it’s convenient for frequent travelers, folding to the size of a carry-on and weighing only 15 pounds. The seat is also compatible with vehicles that have non-removable headrests and can easily fit alongside other car seats when you need to place three in a row. While the booster offers numerous adjustments for child comfort, including recline and width settings, it does not convert to a backless booster and may not be suitable for those looking for a lightweight, convertible option.

What About Seats We Don’t Recommend?
Just like anyone, we have preferences! This goes for car seats, too. If we don’t recommend a car seat, it’s not because it’s unsafe for your little one. All car seats are safe if they’re installed and used properly, are not expired or damaged, and when they’re made and sold by a reputable manufacturer and/or retailer. Click here for our full list of car seats that we do not recommend.
A note about crash-tests
How does the Peg Perego Viaggio Flex perform in crash tests?
Well, that’s a great question. We know that it passes the strict federally required testing that applies to all car seats sold in the United States. But we don’t know exactly how it performs. In fact, that data isn’t released by any official sources in the US — not by car seat manufacturers, not by government agencies like NHTSA, not anywhere!
There are a few third-party websites that claim to offer objective crash test data for a variety of car seats. But we at Safe in the Seat don’t pay attention to that data for a few big reasons. First of all, third-party crash tests don’t actually give us meaningful data! Car seat manufacturers crash-test their products hundreds, even upwards of a thousand times. They crash-test the finished product in every single installation configuration using every applicable-sized crash test dummy, not to mention a whole lot of testing at each stage of the development process, too. So, one or two crash tests completed by another organization just can’t give the same level of information! One or two crash tests aren’t going to represent the overall average performance of any car seat across its lifespan.
