The mat came quickly to my house a bit dirty but was able to clean it. It never straightened out completely some borders are still raised even after a few weeks of use it's a hazard. The mat is very narrow it's only slightly wider than the rolling chair if we move the chair a bit to the sides it's out of the mat and on the wood. The mat moves all the time and it's annoying and dangerous. Since then I've bought another mat from the Swedish competitor slightly larger less than half the price and it's great sticks to the floor and I haven't felt it at all which is what you would expect from a chair mat.
This chair mat is fairly thin. It sits on a low-to-medium pile carpet. The rolling chair's wheels are making substantial dents in the mat which the chair tends to roll into. Moving the chair out of one of these memorized positions is an unpleasant uphill battle.
