ABSTRACT:
An ergonomic support system for receiving supporting the forearm and/or wrist of a person engaged in an activity on a supporting surface comprises a support member of plastic foam material extending longitudinally and laterally and having a bottom surface for resting on the supporting surface, a top surface adapted for receiving the forearm and/or wrist of the person, a transverse dimension as measured between the top surface and the bottom surface, and a peripheral surface extending between the top surface and the bottom surface. The support member exhibits a substantially uniform value of indentation force deflection, as measured by ASTM D3574 Test B1, which is in the approximate ranges of 488 lbf to 34 lbf @10.degree. C., 27 lbf to 4 lbf @21.degree. C. and 9 lbf to 3 lbf @38.degree. C. The support member has a total thickness in the approximate range of one to two inches. An outer covering of substantially taut flexible material envelops the support member contiguous to the bottom, top, and peripheral surfaces to restrain against longitudinal and lateral displacement of the plastic foam material when applying a transverse force to the support member.
