This is a good basic mat. After a week of use however I have noticed "dents" in the plastic where the chair most frequently stands. But it looks good and provides a smooth even rolling surface which is its primary function.
Not very impressed with the thin and flimsy design. This is mid-range priced for a very cheap product. Much greater thickness is required for any carpet application (even lower pile).
I ordered these for others in the office and actually have commercial carpet. These seem to work okay with that carpet. I have an older version of the same mat and it still doesn't roll as well as expected so I was pleasantly surprised that these roll so well. But they do seem a little thin.
