A system for fluidizing a fluidizable medium includes a person support structure, fluid supply, sensor, and controller. The person support structure includes a chamber containing a fluidizable medium and a plenum in fluid communication with the chamber. The fluid supply is in fluid communication with the plenum. The sensor is configured to sense a pressure of fluid in the plenum. The controller is configured to control the operation of the fluid supply as a function of the fluid pressure within the plenum to achieve a desirable level of fluidization of the fluidizable medium.
