Abstract
An improvement for a water bed includes a pair of water bed mattresses housed in a bed cover. There is a heat insulating foam or air bag sandwiched between the two water bed mattresses. Each water bed mattress has a plurality of transverse partitions to reduce water vibration and turbulence therein. The disclosed structure has the advantage of not only improving the stability, but also lengthening the durability of the water bed mattress. A plurality of longitudinal air tubes run through the transverse partitions and communicate with an air bag for providing a desired softness of the water bed mattresses to suit an individual user's requirements. Moreover, the disclosed water bed mattress is able to support a user's back bone comfortably, and minimize the quantity of water used for the mattress to reduce its weight.
