  • Patent number: 5702153
    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.
