Abstract

A high chair features various modes of adjustability and enhanced utility. The height of the chair can be adjusted using a single hand that engages a rear handle. The height of a seat platform of the chair can be adjusted separately relative to the tray. The tray itself is ergonomically designed for the benefit of the caregiver. A removable tray liner facilitates after-meal clean-up. Wheels on the. underside of the tray ease fore/aft adjustment. A pivoting back rest of the chair minimizes rearward shift of the center of gravity of the occupied chair, thus requiring a smaller chair footprint. Further, an accessory bar pivoted to a seat back portion of the chair provides readily accessible entertainment.
