Waterbed System

A waterbed system comprising:

• a) a waterbed mattress;
• b) a platform having a lower surface and an upper surface for supporting the waterbed mattress;
• b) a foundation below the lower surface of the platform and supporting the platform;
• c) a foam structure around the periphery of the mattress, the foam structure having an inwardly sloping inner surface and a bottom surface that meet at an inner corner;
• d) a water vapor permeable cover for the foam structure, the cover having a flap extending from the inner corner formed by the inner and bottom surfaces of the foam structure, the flap having a length, a proximal edge proximate the inner corner of the foam structure and a distal portion;
• and
• e) at least one retainer retaining the distal portion of the flap on the platform.

A waterbed system for placement on a ground surface, the waterbed system comprising:

• a) a waterbed mattress having a periphery, a bottom surface, a top surface, a top surface length of from about 80 inches to about 90 inches, a top surface width of from about 30 inches to about 80 inches, and when filled with water a height of from about 6 inches to about 10 inches;
• b) a foam structure around the periphery of the mattress, the foam structure having an outer surface, an inwardly sloping inner surface, a top surface, and a bottom surface, wherein the inwardly sloping inner surface and the bottom surface meet at an inner corner, and the top surface of the foam structure be substantially flush with the top surface of the mattress when the mattress is filled with water;
• c) a water vapor permeable cover made of flashspun high-density polyethylene fibers for the foam structure, the cover having a flap extending from the inner corner formed by the inner and bottom surfaces of the foam structure, the flap having a length, a proximal edge proximate the inner corner of the foam structure and a distal portion;
• d) a platform below the mattress and the foam periphery for supporting the waterbed mattress and the foam structure, the platform having an upper surface, a lower surface and an upper surface periphery;
• e) at least one retainer configured to retain the distal portion of the flap on the platform;
• f) a cover comprising:
• i) an upper layer over the top surface of the mattress and around the outer surface of the foam structure;
• and
• ii) a lower layer below the waterbed mattress, the lower layer having an exterior periphery proximate the upper surface periphery of the platform and an interior periphery forming an open center, with a plurality of grommets disposed along the interior periphery;
• wherein the upper layer and the lower layer are removably coupled to each other by a zipper that extends along the upper surface periphery of the platform;
• g) a water proof liner for placement below the bottom surface of the mattress, around the periphery of the mattress, over the inner and upper surfaces of the foam structure, and around the outer surface of the foam structure;
• h) a waterbed heater for placement between the liner and the upper surface of the platform;
• and
• i) a water bed heater controller electrically coupled to the waterbed heater for controlling the waterbed heater.

A waterbed system comprising:

• a) a waterbed mattress;
• b) a platform having a lower surface and an upper surface for supporting the waterbed mattress;
• b) a foundation below the lower surface of the platform and supporting the platform;
• c) a foam structure around the periphery of the mattress, the foam structure having an inwardly sloping inner surface and a bottom surface that meet at an inner corner;
• d) a water vapor permeable cover for the foam structure, the cover having a flap extending from the inner corner formed by the inner and bottom surfaces of the foam structure, the flap having a length, a proximal edge proximate the inner corner of the foam structure and a distal portion;
• and
• e) at least one slat retaining the distal portion of the flap on the platform.
