Abstract
Abstract A children's highchair equipped with a removable play and food tray that is readily attachable and detachable from the chair. At forward arm sections of the chair a bar extending between the arm supports fits into a recess on a rearward edge of the tray. The bar serves as a forward child restraint, with or without the tray in place. Shafts extend rearward from the tray, and projections on the shaft fit into aligning holes in the highchair sides to forms, with the holes, locking means attaching the tray to the chair. The tray is pivotal about the bar that secures it in place at the forward end of the arm support sections and the projections on the shafts have latching bosses on their ends that latch about the inside edges of the cooperating holes when slight downward pressure is applied on the play and food surface of the tray.
