It is thin but I don't need a thick one. The chair rolls effortlessly on the mat. It does show wheel indentations as others have said but they go away when the office chair is moved and the wheels are not left in the same location every time.
Love the mat but wasn't happy with delivery. Thought it would come wrapped as it was a gift. instead it was thrown on the front step in the snow fully exposed to weather. husband found it. disappointed as it was a gift for him.
I had first bought the wrong size but when it came it was new in a box. I returned that one to a store and while in the store ordered a bigger size. When it was delivered it was not in a box. It was filthy dirty and probably used. I had to clean it and it didn’t completely clean. I would have returned it and complained but I needed it.
