The present invention relates to a process for the production of a polyurethane foam backed instrument panel. This process comprises slicing a free-rise bun of polyurethane foam to form a skived polyurethane foam, bonding the skived foam to a skin material to form a laminate, optionally, rolling the foam/skin laminate, thermoforming the foam/skin laminate into an instrument panel skin, positioning the instrument panel skin into the cavity of a mold, positioning a retainer into the core of the mold, adhering the retainer to the laminate by placing an adhesive film onto the retainer, closing the mold to apply heat and pressure, and removing the resultant instrument panel from the mold. Suitable polyurethane foams for the present invention may be flexible foams or semi-rigid foams. This invention also relates to the polyurethane foam backed instrument panels produced by this process.
