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.
