The most advanced Monterey expandable booster seat featuring 15 upgrades in safety, comfort and style. From the remodeled headrest and enhanced side impact protection to the contoured seat base and breathable side panels, we've considered every last detail.
Suitable from 18 - 54 kg / 40 - 120 lb (approx. 4 - 12 years) expect 8 years of safety from just one booster seat. Monterey 4DXT adjusts and expands as your little one grows to offer all-round protection. The height and width are adjusted independently providing 69% increase in occupancy space as they grow.
Extra deep aluminum reinforced sides and a combination of EPP and EPS foam provide 3 layers of enhanced side impact protection for their head, shoulders and torso. The ergonomically contoured car seat base improves the child seating position with luxury foam cushioning for child comfort, with two space saving cup holders that can simply fold away when not in use. So, when it comes to your next booster, look to the Monterey 4DXT to take your child on their journey in safety and style.
