Abstract
A pattern of airflow pathways among inflatable air cells in an inflatable air cell cushion that result in discrete, isolated inflation zones that allow the optimal immersion depth and support of a seated,user when fully inflated and maintain acceptable immersion depth and support of the seated user in the event of an air leak from one of the inflation zones. The airflow pathways are operably connected to a valve wherein opening of the valve places the normally isolated inflation zones in fluid communication and closing of the valve isolates the inflation zones.
