Not bad. It works... mostly. My carpet is a bit thicker than I thought so it does dent in a bit but at least I can roll the chair. My fault not the pads. I probably should have gotten a heaver mat... lol.
Had to wait for this but finally arrived at my local store Smooth slide of chair is so good and have not hit my knee on desk (which occurred regularly)
So Far I'm finding the flat carpet Chair mat to be very good I'm hoping that it will remain in it's present condition for a long time.As of now I'm very happy with the Mat.
