This mat made my nice desk chair a pleasure to use! It is a perfect size and the chair easily glides on top of the mat. The smooth side of the mat was quite dusty and needed to be thoroughly wiped. Also there was a very sticky large label that was difficult to remove. Had to use acetone on the residual adhesive.
This chair mat is very stiff and so you would think it would be easy to roll your chair on but it is not. I have to forcibly push the chair with my feet to move it and it is not easy. I would not recommend this mat for carpet. I would also not recommend this mat for hard floors either because it has the pin points on the back side to keep it secured to the carpet. They may scratch your floor.
