I have it under my rolling chair in front of my computer desk so I am able to move so much easier to reach needed items around me on my carpeted area. It is great and just the right size and cleans up so quickly. If I drop anything I still can see what I dropped because it has not discolored .
Works ok. If you sit in one place for a long period of time the wheels on the chair sort of sink in making it a little difficult to move. At least it isn't cracking like the one I had to replace.
This is a decent product for the price. I purchased to use primarily at home. After having a rolling chair and no mat I was determined not to ruin any more carpet. The only con I have is for the shape. Since I have a small desk at home the portion that fits underneath the desk is to short. There is about 11 to 12 inches deep of unprotected carpet. The remainder of the area is just perfect. Great buy!
