Back in 2008, the original American expandable booster seat was created right here at Diono. Fast forward to today as we welcome the next evolution in a long-standing legacy. We’ve taken the award-winning Monterey and painstakingly engineered 15 upgrades to create the Monterey® 4DXT. 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.

We’ve taken all the unique and well-loved features from our award-winning Monterey and introduced 15 upgrades in safety, comfort and style.
Like all Diono boosters, expect up to 8 years of service, so you can rest assured the Monterey 4DXT will be with you for the long haul.
The height and width can be adjusted independently for safety that envelopes their head and shoulders up to 12 years of age.
The ergonomically contoured seat base and remodeled headrest improves the child seating position with luxury AIRTEK foam cushioning for total child comfort.
No, it is too wide to fit 3-across.
There is no installation required. You may place the booster seat directly on the vehicle seat if there are no LATCH connectors. If there are LATCH connectors, the LATCH system on the booster can be used, but is is not required.
The 4DXT comes with an 11 position headrest, expandable seat back, aluminum alloy reinforced sides lined with EPS foam for side impact protection, and a stronger seat back designed for added strength. The Cambria 2 comes with a 6 position headrest and is lined with EPE foam for side impact protection. Both easily convert to a backless booster.
No, there is no top tether.
