Abstract
An air inflatable support appliance which may have internally sealed seams, internal diaphragms and internal structural support members is described. The appliance comprises gaseous mixture permeable, substantially solids and liquids impermeable cushions, used singly or in multiples with attachment to a source of pressurized and optionally heated gaseous mixture. The gaseous mixture flow may be independently controllable for each cushion. The appliance is portable and easily cleaned and is constructed so as not to require an external support frame or base.
