ABSTRACT:
A number of relatively wide, preferably wooden panels are shaped and proportioned to cover the entire areas of a back, a seat, or an end of a sofa or chair. The panels have tabs or hooks and mating slots which fit into each other when the panels come together in a proper fit. At that time the parts are interconnected by wedge-shaped pegs. The shapes, angles and dimensions of these tabs, hooks and slots are such that the panels inherently wedge together more tightly, as the furniture supports the weight of one or more persons. The panels become even more tightly wedged together when the people sitting upon the furniture move and shift their weight. A similar approach enables tables or other articles of furniture to be assembled in a similar manner.
