Abstract
A cushioning device with an upper foam layer and a lower positioned foam layer, with the upper foam layer having multiple thickness zones defined by different height projections from one zone to another as to provide a thickness variation pattern, one side of the upper foam layer is less contoured when not yet assembled in the cushioning device and a second side is comprised of the multiple thickness zones such that, upon connection of the multiple thickness zones to the lower positioned foam layer, the height differential along a length of the upper foam layer is transmitted as to form a non-planar, crown configuration in the upper surface of the upper foam layer. A method includes roller contouring different height and shaped projection zones including zones with different ratios of peak height to overall zone height.
