ABSTRACT:
A collapsible stool including a plurality of slats which are connected in side-by-side relationship by a plurality of flexible material hinges which permit the slats to be positioned in a folded-up configuration for transportation and storage. A pair of arms are pivotably connected to the bottom surfaces of the outer slats, at the opposite corners of the stool, so that the arms may be positioned parallel to the slats or perpendicular thereto. Each arm supports a pair of legs at the opposite ends thereof which are collapsible with the arms or extendable outwardly to support the stool above a surface. A locking mechanism made integral with two of the legs locks the free ends of the arms to the slats when the legs are extended outwardly.
