Abstract
An inflatable pillow top includes a fabric case with an inflatable bladder contained therein. The inflatable bladder is coextensive with the fabric case, and the mattress upon which it is secured. The bladder may be inflated by a conventional air pump with a pressure control, or it may be self-inflating. The self-inflating bladder includes a compressible foam material filling the bladder and having memory to return to an expanded condition. An inlet valve on the bladder permits air to enter the bladder as the foam material expands, thereby filling the bladder with air. An exhaust valve is provided to permit adjustment of the air pressure within the bladder.
