From the manufacturer

Diono Monterey 4DXT 2-in-1 belt positioning expandable booster car seat

Product Description

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 latch 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 20” wide, while the headrest adjusts up to 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. Here at Diono we don’t just stop at superior safety. The ergonomically contoured seat base improves the child seating position with luxury AIRTEK foam cushioning for total child comfort. We’ve even added breathable exo-shell side panels to enhance airflow to keep them cool on the move. We've reduced the width of the vehicle seatback to make installation easier, improving access to vehicle seatbelts and promoting independent buckling. And with easily removable backrest and intuitive belt guides, the Monterey 4 DXT latch offers 2 seats in 1 when they are ready to graduate to a backless booster. Like all Diono boosters, expect up to 8 years of reliable service. So, when it comes to your next booster, look to the Monterey 4 DXT latch to take your child on their journey in safety and style

4.0 out of 5 stars Love it but I have an SUV
By Samantha on November 10, 2021
I’d give it a 4.5. I think the padding could definitely use some improvement but my son is also older so he doesn’t need a super padded seat. I don’t have any issues buckling him. But I have a midsized SUV so there’s room for this large topped seat. If you have a smaller vehicle and it has smaller door frames this may not be for you. It’s super sturdy and my son is super happy!

5.0 out of 5 stars Awesome chair, very good protection and not as HUGE as everybody says!
Reviewed in Canada on July 27, 2021
These pics show the chair in my Mazda CX5. It's a compact SUV and the back seat area is not much bigger than a Honda Civic. All my friends said that this is huge compared to the ones they had some years ago. The sides make it look big, but I swear, this chair is SMALLER than the child seat I just replaced! I had the Evenflow Symphony, and it took up more space than this one! I highly recommend this chair, and hopefully these pics help give some size perspective.
