PURPOSE: To provide general-purpose collapsible furniture allowing free reassembly by using a cylindrical box body of the prescribed shape and strength alone or using a plurality thereof for jointing the sides of reference sizes to each other

CONSTITUTION: Box bodies 1a have cubic shape with the length of all three sides determining a rectangular parallelopiped, set to a reference size, and the length of two sides of box bodies 1b is set to a reference size as well. Then, a plurality of box bodies 1a and 1b, and a plate body 4 are used to assemble a desk B. In other words, the box bodies 1b are stacked on the box bodies la with respective open sections 3 laid at a front in a depthwise direction. In addition, the box bodies lb are stacked on and jointed to the box bodies 1a with the open sections 3 laterally laid at the back, thereby forming leg sections B1. A plate body 4 is placed on the leg sections B1 to form a top plate B2. In this case, the leg sections B1 have the front side box bodies 1a and 1b with the open sections 3 in front, and the rear sides closed with the side plates 2 of the bodies 1a and 1b at the rear side. Also, both of the open sections 3 of the rear side bodies 1a and 1b are orientated in a lateral direction.
