ABSTRACT:
A bed is disclosed, comprising a base having a floor and an upstanding wall extending aroung the periphery of the floor. A body of particulate fluidizable material is contained within the base. The floor has an elongate slit connectable to an air supply and a pair of inclined surfaces extending upwardly on opposite sides of the slit. Supply of air to the slit causes circulation of the particulate material along the inclined surfaces towards the slit and causes fluidization of the upper region of the base.
