I procrastinated for over a year to replace old mat. This mat does not have enough teeth to stay in place as it slips(less than 1") when I move in the chair. I have to adjust every other day. Glad to have finally replaced old mat. Staples was great to deal with!
I would not recommend this product. It is too thin to be worthwhile after just a few days it has large indents from the wheels of the desk chair. Disappointing.
i purchased this mat because i thought it would be stiff enough to not allow sinking. unfortunately my chair alone creates divots in the mat. with my 200lbs and the chair needless to say once i'm seated at the computer i do not move nor can i roll around from one station to the next. i was concerned when it arrived fedex rolled up. it is a good product just not as good as i thought it would be.
