1. A floor mat that resists mat creep movement during use for mat purposes, comprising a sheet having a first side and an opposing second side for disposing on a floor surface for mat purposes, the second side defining a plurality of spaced-apart lugs extending from the second side, each lug comprising a pair of opposing C-shaped nibs, each nib having a planar free distal end in a plane parallel to the second side for load-bearing contact on the floor surface, the pair of nibs disposed in spaced-apart opposing relation with a respective concave face open towards the opposing respective concave face such that a radial line extending from a center point of one of the pair of nibs intersects a center point of the opposing one of the ribs and a passage therebetween with a longitudinal axis in a selected direction of a plurality of directions to define a respective directional characteristic of the lug, the lugs spaced apart such that the passage defined by a respective lug is free of a portion of the passage of an adjacent lug, said selected direction different from the direction of the longitudinal axis of the passage in an adjacent lug and having a directional characteristic different from the adjacent lug, the opposing different directional characteristics cooperatively resisting creep movement of the mat under loading imposed on the mat being used for mat purposes on the floor surface. |
