ABSTRACT:
A person-support apparatus comprises a frame, a container, a gas permeable cover, a rigid diffuser, a fluidizable medium, and a cushion. The container is supported on a frame and includes a base and a plurality of sides coupled to the base. The base cooperates with the sides to define an opening opposite the base. The gas permeable cover is removably coupled to the container and covers the opening to define a chamber. The rigid diffuser is positioned within the chamber proximate the base. The fluidizable medium is positioned between the rigid diffuser and the gas permeable cover. The cushion is coupled to the diffuser and positioned between the gas permeable cover and the rigid diffuser. The cushion is configured to provide cushioning support between a person supported on the gas permeable cover and the rigid diffuser.
