The lower foam cushion includes a plurality of air holes formed therethrough from the top to the bottom surface. A porous trim cover is positioned over the seat back foam cushion and lower foam cushion. A first impeller is positioned in fluid communication with the plurality of air channels for creating a vacuum for drawing heat and moisture away from the trim cover material. Similarly, a second impeller is positioned in fluid communication with the plurality of air holes in the lower foam cushion for creating a vacuum for drawing heat and moisture away from the trim cover material.
