1. A three-dimensional sheet material comprising a first layer of material having a top surface, a bottom surface and a thickness, said first layer of material defining a first plane, a second plane and third plane located between said first plane and said second plane with at least a portion of said top surface being located in or adjacent said first plane and at least a portion of said bottom surface being located in or adjacent said second plane, said first layer of material having a plurality of first depressions depending from said third plane toward said first plane, at least a portion of said plurality of first depressions terminating in or adjacent said first plane, wherein the plurality of first depressions each have an elliptical shape defined by bulbous ends, wherein the plurality of first depressions are arranged on the sheet material in offset parallel rows, wherein the bulbous ends of the plurality of first depressions in a first row are offset from the bulbous ends of the plurality of first depressions in an adjacent second row such that the bulbous ends of the plurality of first depressions in the first row are generally aligned with a midpoint of the plurality of first depressions in the adjacent second row, said first layer of material having a plurality of second depressions depending from said third plane toward said second plane, at least a portion of said plurality of second depressions terminating in or adjacent said second plane.
