  • Water bed
    Patent number: 4015299
    Abstract: A water bed construction includes a box foundation on which rests an upwardly opening rectangular coffer formed by a polyurethane sheet and a polyurethane perimetrical member disposed thereon. The coffer cavity receives and contains a shallow water mattress, and a foam pad is disposed over the mattress. The foam construction obviates the need for a mattress heater, and serves to attenuate resonant frequency phenomena of the mattress. The foam perimeter also permits the use of standard fitted sheets.
