A process for manufacturing a padded element is provided. The process utilizes a mold including an upper mold having an interior surface complimentary to the upper surface of the padded element and a lower mold having an interior surface complimentary to the lower surface of the padded element. A trim cover including a finished outer surface and an inner surface is placed in the upper mold such that the finished outer surface is in contact with the interior surface of the upper mold. A liquid foamable polymeric composition is placed in the lower mold. The upper mold and the lower mold are closed in a manner such that the liquid foamable polymeric composition expands in a direction substantially toward the inner surface of the trim cover and adheres thereto. During expansion (prior to and/or after the upper mold and lower mold are closed) of the liquid foamable polymeric composition, any expansion gases produced are vented.
