I bought this Staples 46" x 60'' Extra High Carpet Clear Vinyl Chair Mat to replace a nearly identical mat that I've been using for more than eight years which recently developed a lot of cracks where I roll my chair around. The new mat looks just like my old ES Robbins AnchorBar Professional Series mat right down to the textured surface but the new mat is a lot thicker. I guess my old mat was one of the thinner variants. My berber carpet is 1/4 inch thick over a 1/4 inch non-compressible pad. In this application the heavy mat does not dent at all under the chair wheels. (Neither did my old one.) The clear color is not exactly what I'd call crystal clear. My white berber carpet looks darker through the clear mat (same for both old and new).
Great floor mat exactly what I had been looking for. Fits perfectly under my make shift desk. Allows my chair to move with great ease. Cost less than the competitor.
