Abstract
A body support such as a cushion, mattress, chair or the like has at least one inflatable air chamber. A pressure sensor senses interface pressures at different locations on a surface of the air chamber. Indicators derived from the interface pressures indicate the onset of a trend toward bottoming out. A controller controls air pressure within the air chamber based at least in part on values of the indicators. The controller may be implemented as a state machine.
