Abstract
An improved support post for cushioning and supporting large products is provided. The post is made from a sheet that is convolutely wound around a mandrel and shaped into a desired shape. The improvement comprises making the sheet from multiple thicknesses of paper so that, upon winding the sheet into a tube, the middle layer of the tube is thicker than the outer layers. The post has a higher axial compression strength than a conventional post, but the same amount (weight) of material.
