Abstract:
1. A multi-layer therapeutic body support apparatus adapted for accommodating a sitting human, the apparatus comprising: a bottom foam layer having a first density and a first indentation force deflection sized and shaped to fit a seating structure; a second foam layer adjacent to and coextensive with the bottom foam layer located above the bottom foam layer, the second foam layer having a second density and a second indentation force deflection, the second foam layer having only a single cavity extending from a first major surface into the second foam layer wherein the single cavity therein is shaped and positioned to simultaneously accommodate in three point relation two ischial tuberosities and a coccyx of a pelvis; and a single pressure relief insert positioned within the cavity of the second foam layer, wherein the insert has a different density than the second density and a different indentation force deflection than the second indentation force deflection of the second foam layer and wherein the single pressure relief insert is shaped to be received in the cutout in closely fitting relation to the cutout; and wherein the first indentation force deflection is greater than the second indentation force deflection.
