I thought the chair mat was difficult to unroll and when I finally accomplished in doing so, it wouldn’t lay flat, and that was a negative.  It was thick enough and transparent in color, which was aesthetically pleasing.  I did notice dents left from the wheels on the mat, so I don’t think “it will last for years to come.” Sorry Regency, but I wouldn’t recommend this product because it just didn’t perform like it said it would.
