The American Sleep Collection Free Flow Waterbed Mattress provides all the pressure relieving support benefits of full depth flotation sleep incorporated in the latest mattress design technology. It is a well established scientific fact that the body can only be truly relaxed when muscles do not have to constantly fight the forces of gravity. Archimedes’ Principle, proved a body floating or submerged in a liquid is buoyed up by a force equal to the weight of the liquid displaced and thus the body thus loses the amount of weight of the liquid displaced so that body weight is lightened and imposes less pressure on the body parts. As your body consists of over 90% water, the deep fill American Sleep Collection Free Flow Waterbed Mattress enables you to float in a near weightless environment that virtually eliminates muscle tension. And Digital temperature control enables you to precisely regulate your environment for the deepest most rejuvenating sleep.
