A thermal layer is integrated into one of the sleep surface build-ups of a mattress, either between resilient layers of a quilted ticking panel or between a pair of resilient layers underlying the ticking panel. By selectively orienting the mattress, a metallic film incorporated in the thermal layer becomes effective to reflect body heat, thereby warming the upper surface of the mattress in contact with a reclining person.
