## Abstract

The present invention relates to a tailbone cushion to eliminate discomfort of patients afflicted with hemorrhoids, fissure, damaged coccyges (tailbone) or the like associated with sitting on hard surfaces. The tail bone cushion of the present invention consists of a cushion section having front, rear and side edges and generally flat top and bottom surfaces. The cushion section has a cutout centrally disposed in the rear edge providing said cushion section with a U-shaped configuration. The cutout is sized and located to eliminate contact between the patient's tailbone and either the cushion or the surface underneath the cushion. The cushion section is preferably tapered in thickness and firmness from rear to front. The cushion section is also preferably formed from a casing filled with a material that has low compression under a patient's body weight yet soft enough to permit sitting for extended periods with minimal discomfort. The tail bone cushion is optionally provided with a back support. The back support has top, bottom and side edges and generally flat front and rear surfaces. The back support is preferably detachably connected to the cushion section by a hinged connection between the rear edge of the cushion section and the bottom edge of the back support to permit the tailbone cushion to be folded flat for storage or transport and opened for use. Means may be provided with said back support to provide a lumbar support preferably a hot pack. The means can include a sleeve or pouch located on the front surface of said back support.
