Claim:
Collapsible furniture, comprising: a. a plug comprising a top side and a bottom side and four vertical sides, each vertical side tapering toward the bottom side, creating a four-sided, truncated pyramid; b. a first furniture part, comprising a top end and a bottom end, such first furniture part further comprising: i. a square hole at the top end for receiving the plug, the square hole comprising four corners and four receiving insides, the four receiving insides of the square hole being slightly smaller than the four vertical sides of the plug, each of the four corners having vertical relief cuts extending from the top end downward for two inches, capable of causing the receiving insides to expand outward at the same rate as the plug vertical sides when the plug is inserted into the square hole in order to securely fix the top end of the first furniture part to a second furniture part and to maximize surface area contact between the receiving insides and the vertical sides; ii. a hollow portion extending from the square hole to the bottom end; iii. a descending cut extending from the top end for several inches, resulting in a ledge capable of receiving another furniture part; and c. second furniture part, comprising an opening capable of joining the first furniture part and resting on the ledge of the first furniture part.
