A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo-moldable at temperatures between about 104° C. and about 127° C., a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer. The stacked assembly is compression molded in a 3-dimensional mold while at least a portion of the foam interlayer is heated to a temperature between about 104° C. and about 127° C. to form the ventilated molded seat trim cover. The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.
