Overprotective in all the right ways, the Monterey is a full-featured, expandable high-back booster seat designed to fit growing children 18 - 54 kg (40 lb to 120 lb).

The adjustable head rest and deep, aluminum reinforced sides are lined with energy absorbing EPS foam for side impact protection and the long seat bottom provides extra leg support. 

A simple-to-use dial on the back adjusts the width of the seat to fit a child’s shoulders up to 50.8 cm (20") wide. The 11-position headrest gives ultimate flexibility and adjusts up to 16.5 cm (6.5") in height with one hand for an easy, precise fit.

As a fixed-position booster, integrated UAS connectors and front adjusters allow for a safe and secure installation in seconds (UAS use is optional) and keeps the seat in position when not in use.

The seat bottom has extra length for leg support and features thick AirTek foam and tapered sides for total comfort.

Retractable, dual cup holders are extra-deep and angled to keep drinks upright.

Monterey can also be used as a backless booster and packs flat for travel and storage.
