A floor mat includes a plurality of projections integrally formed and extending from a lower surface. At least some of the projections have a straight axis and a cross section perpendicular to the straight axis that decreases from the base to the tip of the projection. The at least some projections have a height measured along the axis and a width corresponding to its largest dimension measured parallel to a plane of the lower surface such that the ratio of the width to the height of the projection is greater than 1.
1. A mat for providing non-skid support upon a flat surface comprising an upper surface, a lower surface parallel to the upper surface, and a plurality of projections extending from the lower surface to engage the flat surface, at least some of the plurality of projections having a straight axis and a cross section perpendicular to the straight axis that decreases from a base to a tip of the projection, wherein the at least some of the plurality of projections have a height measured along the axis and a width corresponding to its largest dimension measured parallel to a plane of the lower surface such that the ratio of the width to the height is greater than 1 and less than about 5, wherein the at least some of the plurality of projections include a lower section and an upper section where the upper section terminates in a tip and has a conicity defined by the angle between the axis and an outer surface of the upper section from about 5° to about 60 degrees, and wherein the lower section extends from the lower surface of the mat to the upper section at an angle from about 1° to about 45 degrees.
