E.A. Mattes is the world's leading sheepskin products company with unsurpassed quality, functional attributes and appearance. You'll notice that the top line on all Mattes pads incorporate a high wither with an anatomically correct curvature. All Mattes pads are designed this way to ensure the pad stays in place and does not shift or slide. In addition, for the Correction System, the heavy-duty outer cotton quilt, with the patented Mattes stitching pattern, has been combined with an inner core made from no bounce PolyFlex, which has visco-elastic properties. A material that will not rot, get lumpy or lose its firmness, even after numerous washing.
