Waveless waterbed mattresses

Reducing wave action inside water bed mattresses is accomplished by using mechanisms to dampen and dissappate the waves cause when you move on a water bed. Fiber fill waterbed mattresses use polyester fibers to add cushioning and reduce wave action. The downside with these water beds is that they tend to soak up water and can be harder to drain, causing additional waterbed maintenance. Another type of waveless water bed mattresses is a hydraulic bed. These use round vinyl coils attached to the bottom of the mattress that fill with water and float just near the surface. When you get into the bed, water is pushed through small ports on these coils, and as a result the motion is dampened.
