Abstract
A moisture drying mattress comprised of at least one cushion that has opposite top and bottom surfaces and a plurality of apertures that extend through the cushion from the bottom surface to the top surface. An air channel mat is positioned below the cushion. The air channel mat is adapted and dimensioned to fit beneath the cushion and support the cushion bottom surface in a spaced relation above a bottom base of the mat to thereby form an air flow space between the cushion and mat through which air can flow. A vapor permeable, liquid impermeable cover encases the air channel mat and the cushion defining a vapor evaporation area under the cover. The air channel mat defines a moisture drying zone within the vapor evaporation area. An air pump is provided for selectively supplying a flow of air to the air channel mat. A controller is provided to control the flow of air to the air channel mat to evaporate the vapor in the vapor evaporation area. In an alternative embodiment, the air channel mat is positioned above the cushion.
