And the Winner Is: Diono Monterey 5iST FixSafe

Outgrowing the convertible car seat is a huge milestone for kiddos (and parents too!). When your child surpasses their car seat’s height and/or weight limits, they’re ready for a new, big kid perch. But because they’re not quite tall enough to safely ride with just a seatbelt, a booster seat gives them, well, a boost. The Monterey 5iST FixSafe booster by Diono checks all the boxes—it grows with your child, folds up for ultimate portability and is 25 percent smaller than the average booster, giving your backseat a roomier ride. Rigid latch connectors make installation easy and secure. You can adjust the height and width of the seat with one hand, perfect for rapidly growing kids. The fold feature is by far our favorite—it goes from compact to full size in seconds, with a built-in handle and straps for easy carrying. It’s the perfect choice for city dwellers and globetrotters alike.

What We Love

• It provides a safe ride, with eight layers of side impact protection, plus rigid latch connectors for secure installation

• Expands in height and width to grow with your child

• The seat is 25 percent smaller than the average booster, giving you more room in your backseat

• The Monterey folds in seconds and includes carrying straps for easy transport while traveling

• Machine-washable fabric and an included cup holder make it a comfortable ride for your kiddo

Buy it: $250, Diono.com
