Suitable from 18 – 54 kg / 40 – 120 lb From 96 – 160 cm / 38” – 63” tall (approx. 4 – 12 years)
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 side panels, we’ve considered every last detail to create a contemporary new look.
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.

16.98lbs / 7.7kg
8 Years One Booster
One thing all parents know, kids will keep on growing! diono boosters offer some of the largest seat capacities and extensive height adjustibility for up to 8 years of service.
REINFORCED HEAD SUPPORT
The further the child’s head travels in the case of a collision, the greater the risk of serious injury. Diono high back boosters are all designed and engineered with reinforced head support to provide head containment and minimize side movement. As your child grows, the head support is adjusted to ensure that their head is protected throughout the life of the booster.
TESTED OVER AND ABOVE
Diono’s commitment to child safety is not just driven by industry standards but by the need to always go above and beyond the regulatory requirements to delivery products that serve and protect.
