ABSTRACT:
A softside waterbed foundation includes a pneumatically inflatable base and a compressible collar extending around the periphery of the base. The collar extends upwardly from the base to define a cavity for a water mattress. The base includes anti-bowing structure for preventing the base from bowing upwardly in the center during and after inflation. Alternatively, the base is composed of compressible, resilient foam, as is the collar. In the alternative construction, there is a closed vinyl shell enclosing the collar and the base. The shell has a closable port therethrough so that air in the closed vinyl shell may be evacuated through the port to reduce the volume of the collar and base for shipping. Because of its unique construction, the foundation and a water mattress may be shipped in a box having a girth plus length of no greater than 130".
