ABSTRACT:
An improved pad or liner for overlaying a mattress, including at least one panel having a flexible thermoplastic elastomeric honeycomb core encased within a permeable fabric covering. The honeycomb core is formed of undulated strips of resilient thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells having an upper and a lower extremity. The cell walls of the core are formed with a plurality of perforations. The upper extremities of each cell wall are planarized and a perforated facing sheet is thermal compression bonded to the lower extremities of each cell wall. The planarized extremities and the facing sheet maintain and retain the cells of the honeycomb core in their expanded configuration so that the core can anisotropically flex to stabilize and spread the load exerted by a user of the mattress pad.
