An insert for ventilating a vehicle seat having a frame and cushioning supported on the frame covered by an air permeable cover covering the cushion includes an air permeable spacer having a top surface for facing the covering, a bottom surface for disposition in a recess in the cushioning, and an edge surface between the top and bottom surfaces. A non-air permeable spacer cover enveloply covers the spacer. At least one opening in the cover disposed peripherally around the edge surface of the spacer communicates air through the openings. An air supply opening in the cover aligned adjacent the bottom surface communicates air through the spacer material and the at least one opening in the cover.
