ABSTRACT:
A resilient pad has a uniform patterned patient support surface, including a plurality of parallel ribs. Each rib has a like profile of stacked compressive steps of varying widths. Progressive collapse of the steps under different loading results in differential resilient support responsive to such loading. Troughs between adjacent ribs have profiles identical to that of the ribs when inverted so that two pads may be simultaneously manufactured in mutually-facing, complementary alignment. Rib rocking action reduces the transmission of shear forces to a patient, while rib compression provides an air pumping action for circulating air about the patient.
