A tubing plank is fabricated from foamed tubular members positioned parallel to and adjacent each other, the members having substantially coplanar longitudinal axes, and each member secured to each adjacent member along adjacent sidewalls to form a planar member. A sheet member may be applied to at least one face of the tubing plank, each sheet member forming a contact area. In another embodiment, tubular members are positioned parallel to and spaced apart from each other, adhered to at least one sheet member. A second sheet member may be adhered to the opposite face of the tubes from first sheet.
