Right now this Diono Monterey High Back Booster Seat $59.99 (Retail $119.99).
Overprotective in all the right ways, the Monterey is a full-featured, expandable High Back Booster Seat designed to fit growing children 40 pounds to 120 pounds. The adjustable head rest and deep, aluminum reinforced sides are lined with energy absorbing EPS foam for side impact protection and the reinforced seat bottom provides extra lap belt safety. This significantly strengthens the Monterey and provides superior defense against crash forces. A simple-to-use dial on the back adjusts the width of the seat to fit a child's shoulders up to 20 inch wide. The 11-position headrest gives ultimate flexibility and adjusts up to 6.5 inch in height with one hand for an easy, precise fit. As a fixed-position booster, integrated Latch connectors and front adjusters allow for a safe and secure installation in seconds (Latch 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.
