Abstract
The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable.
