Unfortunately the mat was not quite as thick as I was expecting for the price. I am a fairly light person and my rolling chair leaves dents in the mat with regular use on a daily basis. I am wondering how long it will last.
Looking for a chair mat that would work on berber carpet. Everything was way too expensive except this one. So far it has held up to me moving aound quite well. The real test will come in the coming months. Will it crack chip or split? Hopefully not. It is quite resilient. Indentations show immediately after use but soon return to being close to flat leaving no real noticeable trace of where I or anyone else might have been sitting for hours. I would have given it a higher rating but time will tell how it holds up. So far so good!
Although it has nubbies to supposedly grip the carpet it still slides on carpet and bunches up against anything solid. Then it is difficult to get it to lay flat again unless you put something very heavy on it for several days. Maybe if the nubbies were larger or longer to grab the carpet better it might make a difference.
