ABSTRACT:
A seat pad and backrest enclose a plenum into which pressurized air is provided from a closely adjacent Peltier air temperature and humidity modifying apparatus (either cooled or warmed). A metallic mesh is part of the seat pad and backrest and warms or cools the user by conduction. Alternatively, the seat pad and backrest can be separate each having its own plenum, and modified air is provided to both via a selectively adjustable proportioning valve. Yet another alternative unitarily incorporates a seat pad and backrest into a chair with a single plenum fed temperature modified air from a Peltier unit mounted on the chair.
