ABSTRACT:
A furniture member includes a back wall, two sidewalls, a bottom wall and a top wall, which can be constructed framelike or solid. In order to facilitate disassembly, transport in a small space, and assembly and disassembly without tools, and to assure sufficient stiffness of the assembled furniture member, a post is provided on each side of the back wall, each post being wider than the back wall so as to project forwardly and rearwardly beyond it. Each sidewall has, in its rear region, a recess which receives a respective post of the back wall, each sidewall being connected to the associated post by upper and lower pivot joints. The pivot joints of the respective sidewalls are arranged on opposite sides of the back wall, so that in a collapsed condition each sidewall lies on a respective side of the back wall. The bottom and top wall are each connected to the sidewalls by two separable swivel joints arranged in the front regions of the sidewalls and, during rotary movement and depending on the direction of rotation, cause the top or bottom wall to move into or out of a condition tightly pressed against each of the sidewalls.
