How about a weight of person plus chair added to the description for more accurate useage of the mat? This was an economical mat for the low pile carpet use but I am not sure if the weight of the chair owner plus the chair will stand up to the mat's life.
Does the job well. We all know that eventually these things give out and become brittle. This one seems a little thicker and a little more "flexible" so we'll see what happens in a year from now. Quite honestly these things weren't meant to last "forever" but if it lasts longer than a cheaper brand it's all good! We got this one on sale for a really good price which made it all the better!
