US Patent 7146663 Slipcovers for support pillows

A support pillow comprises a cushion body having a medial region and two opposing arms that define a generally open well, with the cushion body having an outer periphery and an inner periphery adjacent the well. A shell encompasses the cushion body. A fabric cover is removably disposed over the shell such that the fabric cover generally conforms to the shell. The fabric cover defines an opening to permit the cover to be placed over the shell, and the fabric covering includes at least one fastener to close the opening once the cover has been placed over the shell.
