A pillow casing according to the present invention comprises a top surface and a connected bottom surface which cooperate to define an enclosure for receiving a compressible filler therein. The pillow casing further includes a thin envelope layer intermediate the surfaces and attached to the bottom surface. The envelope layer is adapted to sealably receive a fluid-like material therein to form a thin fluid-like layer remote and isolated from the top surface when the compressible filler is received in the enclosure. The filler, when received in the enclosure, is supported by the envelope layer to effectively float the received compressible filler on the fluid-like material received in the envelope. The pillow casing is particularly adapted for receiving a conventional pillow as the compressible filler material therein. Thus, the pillow casing can cooperate with a conventional pillow to substantially alter the pillow characteristics of the combination by floating the pillow on a thin layer of fluid. The invention is also directed to a complete pillow, in which case a compressible filler material is inserted into the pillow casing at the time of manufacture. |
