  • Patent number: 10993538
    Abstract: A seat apparatus includes a base having a central ridge structure on the top of the base. The central ridge structure is round on the top and slopes downward from front to back. A secondary ridge structure may be included on top of the central ridge structure. Using the seat apparatus, a person with a hemorrhoid condition can sit on the seat apparatus, and using their own body weight, create pressure between the affected area and the central ridge structure. The pressure bias the hemorrhoid to be repositioned in the user's body, relieving discomfort and, with long term use, can improve sphincter control to better prevent hemorrhoid conditions.
