i have an office chair and it doesnt roll on this mat. i have to shift all my weight to get the chair to move. i would not recommend this to anyone. i was wondering why some of these mats cost $100 considering they are just a piece of plastic. i guess you get what you pay for.
I bought this to place on a carpet floor and was told it would work. My chair works great able to roll where I need to. The problem is that it the mat moves VERY easy does not stay in place.
