The pressure relief cushion is divided into two groups of air cells, the primary and secondary groups. The secondary group (marked by Xs in the photo at right) typically includes the cells located under the ischial and sacral area and the primary group includes all other cells. However, a different configuration can be made to address specific client needs. Utilizing the two zone system, the primary area of the cushion is simply inflated to a comfortable pressure and the secondary area remains un-inflated for maximum relief immediately under the boney prominences.
