The mat is over what I would consider an average home carpet pile. After sitting in my 5 wheel office chair for a few minutes the wheels sink in. It is difficult to roll. The mat is too flexible or soft for home carpet
My carpet is not totally flat but a very low pile carpet. This mat is too thin for even low pile. The feet of my chair make impressions in the mat after sitting for a while in one spot. Read the description with that in mind.
