The Diono Monterey 4DXT Latch 2-in-1 High Back Booster Car Seat features 15 upgrades in safety, comfort, and style from our original Monterey XT. From the remodeled headrest and enhanced side impact protection to the contoured seat base and breathable side panels, we’ve considered every detail. Suitable from 40 – 120 lbs (approx. 4 – 12 years), expect 8 years of safety from just one booster seat. The adjustable height and width provide a 69% increase in occupancy space as they grow and the ergonomically contoured seat improves child seating position with foam cushioning for comfort, and two cup holders that can simply fold away when not in use.
The extra deep aluminum reinforced sides and combination of EPP and EPS foam provides 3 layers of enhanced side impact protection for their head, shoulders, and torso. The Monterey 4DXT is also equipped with LATCH connectors and front adjusters to connect the booster seat quickly and securely to your vehicle, enhancing safety and stability. The Monterey 4DXT comes in a range of bold colors, meaning there is a Monterey that suits every child and with an easily removable machine washable cover, the Monterey 4DXT is easy to look after and keep the clean day in, day out.
