ABSTRACT:
A waterbed system is provided. The waterbed system comprises a water fillable bed mattress, a plurality of transverse partitions, an air bag unit, and a bed protecting cover. The plurality of transverse partitions serve to dissipate the water disturbances caused by the weight and movement of a user, and enhance the stability and structural integrity of the mattress when filled with water. Those portions of the water fillable bed mattress at which components are joined are thus subjected to less pressure and stress and, consequently, the threat of water leakage is minimized. In certain embodiments, at least one longitudinal partition is also disposed within the water fillable mattress to isolate water disturbances in one set of transverse partitions from propagating to another set of transverse partitions, if any. The longitudinal partition is formed with water openings spaced in offset manner. The air bag unit is adapted to receive pressurized air whereby the firmness of the water fillable bed mattress may be adjusted.
