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 side panels, we’ve considered every last detail to create a contemporary new look.

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 20” wide, while the headrest adjusts up to 6.4” height with one hand for an easy precise fit.

monterey 4DXT features the Diono 3-layer Side Impact Protection System built in.

The ergonomically contoured seat base and remodelled headrest improves the child seating position with luxury AIRTEK foam cushioning for total child comfort

Like all Diono boosters, expect up to 8 years of service, so you can rest assured Monterey 4DXT will be with you for the long haul.
