摘要： A dismantleable chair comprising a back member, leg members and a seat member all formed from generally two-dimensionally shaped materials such as plywood, and the like. The back member is somewhat arcuately shaped in both the horizontal and vertical cross-sections to provide superior seating comfort and strength. The arcuate shape also provides for a unique curved compressively pre-loaded joint design among the chair members, which substantially increases the strength and rigidity of the chair. The compressively preloaded joints are protected from bending and rotational loads by their respective positioning, and the presence of other spaced apart joints. The chair can be assembled and disassembled numerous times without loosing strength and rigidity.
