Diono Monterey 4DXT Latch 2-in-1 High Back Booster Car Seat

The Monterey 4DXT booster seat is the next generation of Diono's award-winning designs, meticulously engineered with 15 key upgrades. From the remodeled headrest to the enhanced fabric, contoured seat base, and breathable exo-shell panels, every detail has been thoughtfully considered to create a contemporary, stylish look.

Designed to fit and shape seamlessly with your child's growth, the Monterey 4DXT adjusts and expands as your little one grows, offering comprehensive protection up to 12 years of age. The height and width can be independently adjusted, ensuring a secure fit for their head and shoulders. A simple one-handed dial on the back allows the seat to expand up to 20 inches wide, while the headrest can be raised up to 6.4 inches for a customized, precise fit.

The remodeled headrest is lined with thick EPP foam, providing enhanced comfort and improved side impact performance. This is further reinforced by deeper side wings and Diono's 4-layer Side Impact Protection System, engineered with an EPP foam coating, molded rigid shell casing, and EPS-coated outer shell to keep your child safe, mile after mile.

Diono's commitment to safety is matched by their focus on comfort. The ergonomically contoured seat base features luxury AIRTEK foam cushioning, promoting an optimal seating position for your child. Breathable exo-shell side panels have been added to enhance airflow, keeping them cool and comfortable on the move.

To simplify installation, the Monterey 4DXT features a reduced vehicle seatback width, making it easier to access the vehicle seatbelts and enabling independent buckling. The backrest can be easily removed, transforming the booster into a backless design when your child is ready to graduate.

Like all Diono boosters, the Monterey 4DXT is engineered to provide up to 8 years of reliable service, adapting to your child's growth and needs. With its adjustable headrest, 2-in-1 cup holder and snack tray, and premium soft fabrics that can be machine-washed, the Monterey 4DXT is the comprehensive solution for your growing child's safety and comfort.

The Monterey 4DXT's safety features are uncompromising, with 2 layers of SafePlus Side Impact Protection, a rigid shell reinforced with high-impact aluminum and EPS energy-absorbing foam, and easy-access seatbelt guides to promote independent buckling. When it comes to your child's safety and well-being, the Monterey 4DXT is the trusted choice to accompany them on their journey.
