Automatically configured hydraulic support pillow

A pillow comprising:

• a covering layer defining an exterior surface of a pillow and an interior cavity of said pillow;
• said pillow having at least one reservoir chamber defined by a reservoir sidewall, housed in said interior cavity;
• said pillow having at least one receiving chamber housed in said cavity;
• a conduit communicating between said reservoir chamber and said receiving chamber thereby providing a flowpath for fluid therebetween;
• means to prevent flow of said fluid from said receiving cavity to said reservoir cavity;
• said reservoir chamber being compressible by a human head to thereby force fluid container therein into said receiving chamber;
• said receiving chamber formed of a sidewall defining an interior cavity having a total volume;
• said sidewall being elastic to thereby provide a means to increase in size to increase said total volume of said interior cavity of said receiving chamber to accommodate said fluid received from said reservoir chamber;
• said exterior surface of said pillow adjacent to said receiving chamber increasing in size in direct proportion to any increase in said total volume of said interior cavity of said receiving chamber;
• and
• whereby the head of a user contacting said reservoir chamber imparting force upon said reservoir chamber will cause said receiving chamber to enlarge thereby dimensioning said exterior surface to a shape similar to the shape of said head.
