Abstract

A cabinet structure includes a parallelepiped frame having a top side, a bottom side, a front side, a rear side and two opposite lateral sides. A drawer is provided on the upper portion of the frame, having a front panel comprised of four boards overlapping each other and releasably secured together by means of a bolt. Two L-shaped door panels are respectively hinged to two opposite sides of the frame to openably cover the front side. By opening the two door panels to be opposite to each other and un-folding the boards of the front panel of the drawer to have the boards supported on the L-shaped door panels, a stair-like platform ladder is formed with the top side of the cabinet serving as the platform. A safety rack is provided on the platform and is collapsible into a channel formed inside the cabinet so as to be selectively expanded when the cabinet is converted into the platform ladder. A bench includes a horizontal top plate having a first end movably received within and supported by the cabinet and a second end selectively extendible out of one of the lateral sides of the cabinet and supported by a vertical support plate so that the bench is selectively expanded from the cabinet. A stool is removably stored inside the cabinet and is selectively and removably mounted to the platform to provide an additional step to the ladder.
