a stacked assembly of an upper textile layer of one or more of a fabric, perforated vinyl, and/or perforated leather, an air permeable thermo-moldable polyurethane cellular foam interlayer, a first thermoplastic polyurethane (TPU) film layer, and a scrim backing layer of a woven or non-woven textile;
wherein said stacked assembly is compression molded in a 3-dimensional mold while at least a portion of said foam interlayer is heated to a temperature of between about 104° C. to about 127° C. to form said ventilated seat trim cover;
wherein said first TPU film layer prevents airflow passing through a bottom surface of said ventilated seat trim cover; and
wherein airflow passing between said foam interlayer and an external environment adjacent said upper textile layer passes through said upper textile layer.
