Dependable safety for growing children
The monterey® XT booster keeps children from 40-120 pounds and up to 63 inches tall safe and secure with aluminum reinforced sides lined with energy absorbing EPS foam. This seat was designed to accommodate growth spurts without sacrificing protection.
We know how to keep back seat snackers happy. This booster comes with retractable cup holders to keep drinks or snacks upright and within reach.
Side impact protection
This booster comes with deep, aluminum reinforced sidewalls that provide excellent side impact protection, and the energy absorbing EPS foam surrounds your child for ultimate safety.
Adjustable, supported fit
With 11 headrest positions, this booster adjusts for a proper fit and improved comfort for growing children. A simple-to-use dial on the back adjusts the width of the seat to fit a child’s shoulders up to 20″ wide.
Quick, secure installation

“I own the monterey XT booster by diono in heather grey. I love that it is lightweight if we need to switch it between my husband and my vehicles. It is a great investment because it'll carry you through as your child grows. The headrest easily moves up and down and the side panels can be expanded by quick and easy rotation on the back. We really like this booster seat and trust that it will keep our child comfortable and most of all safe.”
