This is the third chairmat I have owned in 10 years. This model was the first followed by one from a different company which was NOT adequate and lasted only 1 year so-o-o-o I bought this one again. As a budget shopper the second one purchased was a total waste of money while this one is more than worth the extra I had to pay.
Perfect size for the "L" shaped desks we ordered. Chairs roll over it smoothly and stays in place. Have had them for 9 months and they are holding up well.
I would think this mat would work fine on the real low-pile commercial grade carpet (i.e. the stuff that is about 2mm high). I would not think that I have a high-pile carpet but my chair will not evenly roll across this mat on my home carpet. but the mat has held up. but it now has indentions because the chair pushes through the mat due to the fact that it sits unevenly on the carpet that I have due to the pile height.
My carpet was too thick for this mat to handle. It immediately developed 'ruts' from the chair wheels and it became difficult to roll freely. I would recommend spending a little more for a thicker mat. The economy mat is not worth the day-to-day aggrivation of not being able to move freely.
