ABSTRACT:
A cushion having a series of pods connected in a matrix configuration. The pods are deformable in response to a person seated on the cushion. The pods cooperate to define primary airflow channels through the cushion from side edge to side edge, and from front edge to back edge, thereof. In one feature, a series of cruciform configured recesses are defined in the pods' top surfaces. These recesses cooperate to define secondary airflow channels through the cushion from side edge to side edge, and from front edge to back edge, thereof. In another feature, a series of first pods are located in those cushion areas which underlie and support a person's ischial and coccyx bones, and a series of second pods located in those cushion areas which do not underlie and support a person's ischial and coccyx bones. The first pods have a relatively thin wall covering a foamed interior and are of a relatively greater height to provide relatively soft pods. The second pods have a relatively thick wall covering a foamed interior and are of a relatively lesser height to form relatively firm pods. These difference in load bearing characteristics between the first and second pods aids in minimizing the pressure on a user's ischial and coccyx bones when seated on the cushion.
