This is my 2nd chair mat for this year...my 4th in 5 yrs...normally they last me about 1 year but this one didn't. Having read ALL the reviews on more expensive mats [really more expensive] I decided to go w/this one since it seems to last just about as long as the others. My carpet is not extremely thick nor very thin and I am of average weight [150] so the fact that the mats ALWAYS crack and eventually just give up seems to be endemic to the product! Hope they come up w/one that will last longer then 6 months!
This mat should only be used on very thin carpeting. The description says low pile and that is very important. The cleats make it unsuitable for bare floors.
Why do you buy a mat? So chair's rollers won't press into carpet and chair will roll easily. Neither happens with this mat. The castors will dig into the mat and chair will not roll. If you don't get up and move the chair periodically it will dent through the mat into the carpet. I weigh 165 lbs so nothing out of ordinary there.
The mat has shallow teeth and does not cling to the carpet as it should. The office chair feet sink into the mat and the chair is VERY hard to roll across the mat. Then the mat has little valleys where the chair has been. Very flimsy construction. [...] For the price it should be four times the quality.
