A wave-reducing water mattress for water beds has a wave-reducing baffle comprising a flexible fibrous layer, preferably of polyester fibers, occupying a major portion of the horizontal area traversed by the water-filled mattress. The fibrous layer resists flow of water within the mattress so as to restrict wave motion within the mattress. The baffle preferably includes a low-density layer that floats the fibrous layer next to the top surface of the water-filled mattress for restricting topical wave motion at the top surface of the mattress. In one embodiment, the baffle comprises a pair of thin vertically spaced apart upper and lower fibrous layers and a thin low-density, non-water absorptive foam layer between the fibrous layers for floating the upper fibrous layer next to the top surface of the mattress, while the lower fibrous layer "anchors" the baffle within the mattress, without the baffle being attached or sealed to the wall of the mattress. Wave motion generated within the mattress is dampened in a water-filled chamber formed between the lower fibrous layer and the floating upper fibrous layer. In another embodiment, the lower fibrous layer and the floating upper fibrous layer are held in place spaced apart with respect to one another by a series of ties or button tufting mono-filament strings which resist wave forces generated within the inner chamber by preventing the two layers from expanding further than the strings allow.
