US Patent 10098463 Ergonomic seat cushion

The ergonomic seat cushion is adapted to receive the buttocks and coccyx of a person in such a manner that a person sits comfortably for extended periods of time. The ergonomic seat cushion comprises a plurality of rings and an upholstery. The upholstery covers the plurality of rings. The location of the aperture within each ring selected from the plurality of rings suspends a body part selected from the group consisting of the left buttock, the right buttock, or the coccyx. This suspension relieves the selected body part from carrying the weight of the person during sitting. Furthermore, the inner perimeter of the selected ring provides lateral pressure against the body of the person providing further support and comfort.
