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.
