Abstract
Abstract A seat device for alleviating backache symptoms by a laminated structure of rigid material covered by resilient material. The rigid material may be preferably wood or plastic and the resilient lamination may be from rubber. The shape includes a spacing portion from the back portion to a point considerably short of the front rim. The spacing portion is shaped on a T with an enlargement section to accommodate the genital area of a seated person. The back portion is designed to alleviate stress and pain on the coccyx of the seated person which is responsible for major backache symptoms. The enlargement area allows for circulation to the genitals and anus for proper ventilation of the genitals to avoid excessive persiration in these areas.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
A seating device for alleviating backache including; top and bottom laminations assembled together and defining front and back portions and two side portions, an entire front rim and a back rim on said laminations, said passageway extending from said back rim completely through said laminations in said back portion for allowing a seated person's coccyx to be relatively free of mechanical stress and pain, said passageway comprising two openings, a first longitudinal one said opening extending inwardly of said device and joined with a second transverse one said opening perpendicular to said first opening said two openings together defining a substantially T-shaped configuration allowing freer flowing circulation of air to the genital area of a seated person, said front rim being completely extensive across the entire front portion of said seating device between said side portions, a plurality of holes disposed within said bottom lamination for venting purposes, said top lamination made of compressible foam material enhancing heat reduction, at least certain of said plurality of holes disposed adjacent to said front rim angled downwardly and inwardly at substantially a 30 degree angle to the vertical thereby increasing air flow when said top lamination is compressed, and said plurality of holes including holes adjacent said two openings to increase ventilation to the genital area of a seated person.
