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.

Moisture drying mattress with separate zone controls

A moisture drying mattress comprises a cover that encloses an air cell mattress and a plurality of air channel mats. The cover has a top portion that is vapor permeable and liquid impermeable. The air cell mattress has a plurality of apertures between the air cells. The plurality of air channel mats have a base and are positioned beneath the air cell mattress and within pockets located in the interior of the cover on a bottom portion of the cover. The air channel mats have a plurality of projections extending upwardly from the base that support the air cell mattress in a spaced relation from the air channel mat base. The air channel mats communicate with an air pump that is selectively controlled by a controller to selectively supply a flow of air to any of the air channel mats. The air flow to the air channel mats flows over the base of the air channel mats between the projections and upwardly through the plurality of apertures in the air cell mattress and through the cover top portion to remove moisture from the mattress and from the interface between a user of the moisture drying mattress and the top cover.

A wheelchair back support assembly is both lightweight and sturdy, is designed to be inexpensively retrofit to an existing wheelchair of tubular frame construction, is designed to comfortably support the back of wheelchair user's of different sizes and having different physical characteristics and also flexes and moves relative to the wheelchair in response to movements of the back, shoulders and arms of the wheelchair user to thereby provide comfortable dynamic support to the back of the wheelchair user.
