The most important consideration when buying a portable booster seat for a “big kid” is, of course, safety. But oftentimes parents mistake heft and size for protection. That assumption can lead to constant headaches for parents with kids who often carpool to and from school or soccer practice in other people’s cars, or who just have a revolving cast of riders in and out of their own backseat. That makes these booster seats, which can deflate, roll up, and disassemble small enough to be conveniently portable, an especially attractive buy for kids on-the-go. All of them meet up-to-date standards set by the American Academy of Pediatrics on booster seat safety as well as our high criteria, including safety testing, consumer reports, and compactness. Plus, some of them come with cupholders.

The Mifold Grab-and-Go‘s primary perk is how lightweight and portable the booster seat is.

Instead of boosting a kid up to make a seatbelt fit, the Mifold locks the seatbelt down at the perfect height in any car. Made of an aircraft-grade aluminum and a “super tough plastic polymer,” it comes in six colors, including blue, pink, green, and yellow.
