Abstract: A high chair is equipped with a tray system incorporating a multiple tray structure that is positionally adjustable relative to the high chair structure. The tray system includes a smaller lower tray formed with rearwardly extending, horizontal posts that are received within horizontally aligned sockets in the high chair structure. The distal ends of the tray posts are provided with rollers, and the high chair sockets have rollers, to provide for a smooth insertion of the posts into the sockets. The larger upper tray is detachably mounted on the lower tray for positional adjustment with the lower tray by releasing the tray posts for movement within the high chair sockets. The larger tray is formed with a depression to allow access to the position adjustment actuator. A third tray can be supported on the larger tray to facilitate cleaning of the tray system.

Abstract: A reversible food and game tray device for use with a child safety seat includes a two-sided tray that is easily reversible between two sides. One side includes a generally flat surface on which books, toys, games, and the like may be rested for use by a child. An opposed side defines multiple recesses for holding plates, cups, napkins, food, and drink items. The tray includes coupling elements for holding the tray in place as well as for enabling the tray to be quickly and easily reversed between the game and food surfaces. The coupling elements include at least one pin cooperatively positioned for releasably engaging a track. Preferably, two pairs of pins are provided along with a control lever for selectively retracting a selected pair of pins. Operation of the lever enables the tray to be pivoted, slid, and thus reversed.

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.
