Abstract
A seat cushion extends across left and right areas that are located beneath the locations of the left and right ischial tuberosities of a seated person. A support structure beneath the cushion transmits a weight load from the cushion to the seat frame. The support structure has portions that surround the left and right ischial areas to provide the cushion with underlying, load bearing support at the peripheral boundaries of the ischial areas, and is free of load bearing portions located within or beneath the ischial areas.
