  • Patent number: 6997513
    Abstract: Disclosed is a supportive chair for sitting comfortably at low heights above and relative to the ground. Preferably, the chair comprises a primary seating surface and a secondary seating surface curving around the rear of the primary seating surface to provide additional support for the user. It is preferred that the secondary seating surface be inwardly and downwardly sloped and provide a low lateral boundary for the user, thereby promoting proper alignment of the buttocks on the primary seating surface. Thus, the chair raises the buttocks and hips of the user off of the seating level, creating a relative height difference between the hips and legs. This raising of the hips relative to the legs creates a sitting posture that promotes vertical back alignment. As a result, the user is able to comfortably maintain this position with a reduced amount of back muscle strain, allowing prolonged comfortable seating periods.

    Abstract: 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.
