ABSTRACT:
A collapsible furniture structure comprises a pair of free standing vertical support elements and a pair of rigid, U-shaped frame elements. Orifices are formed in the upper portions of the vertical support elements in which the extremities of the U-shaped frame elements are inserted and supported. The orifices are oriented and located so that, in the case of a chair, one of the frame elements extends forwardly from the support elements to define a seat portion of the chair while the other of the frame elements extends upwardly from the support elements to define a back rest portion of the chair. A cushion may be placed over the mounted frame elements for added comfort. Additional orifices may be formed in the lower portion of the vertical support elements into which additional floor engaging frame elements are inserted to provide a wider base to the structure. All frame elements are readily removable from the orifices to disassemble the structure for moving or storage.
