Adjustable back restaurant highchair

Abstract

An adjustable back restaurant highchair is a restaurant style highchair with an adjustable back system. The back section of the highchair moves in its entirety, forward and backward along the seat section. Each corner of the seat back is provided with a pin that rides in four (4) corresponding adjustable tracks. Movement is enabled when a parent or care provider lifts the seat back up slightly, slides it forward or backward, and lowers it back into the tracks. Such adjustability accommodates children of all sizes, while ensuring that the smallest of them remain upright and cannot slide down. This eliminates the current practice of bracing the child up with towels, blankets, or coats, that are jammed in between their back and the seat support. The device remains stackable and keeps the simple design of its conventional counterpart.
