We've taken the award-winning Monterey and painstakingly engineered 15 upgrades to create the next generation of boosters. From the remodeled headrest, enhanced fabric covering, contoured seat base and breathable exo-shell panels, we've considered every last detail to create a contemporary new look.

Contoured to fit and shaped in harmony with your child, Monterey 4 DXT adjusts and expands as your little one grows to offer wonderful all-round protection. The height and width can be adjusted independently for safety that envelopes their head and shoulders up to 12 years of age. A simple-to-use dial on the back adjusts the width of the seat to fit a child's shoulders up to 51cm/20" wide, while the headrest adjusts up to 16.5cm/6.4" height with one hand for an easy precise fit.

The remodeled headrest is lined with thick EPP foam for better child comfort and improved side impact performance. This is combined with deeper side wings and Diono 3-layer Side Impact Protection System built in. From the EPP foam coating, to the molded rigid shell casing and EPS coated outer shell, we've lovingly engineered every detail to keep your little one safe, mile after mile.
