Abstract:
A dimensionally stable mattress and furniture insulator pad, comprising:a core foam sheet formed from rebonded polyurethane foam having an upper surface and a lower surface; a first stiffening layer having an upper face and a lower face, wherein the lower face is attached to the upper surface of the core foam sheet; a second stiffening layer having an upper face and a lower face wherein the upper face is attached to the lower surface of the core foam sheet; a first outer polyurethane foam sheet attached adjacent to the top face of the first stiffening layer so that the first stiffening layer is substantially completely covered by the outer foam sheet; and a second outer polyurethane foam sheet attached adjacent to the bottom face of the second stiffening layer so that the second stiffening layer is substantially completely covered by the outer foam sheet; so that the core foam sheet with first and second stiffening layers and first and second outer foam sheets attached thereto forms the dimensionally stable mattress and furniture insulator pad with a sufficient stiffness to resist bending and telegraphing.
