The size is good - but it moves around too much. Had to put weights on it to keep it from moving. It should have been a high pile carpet protector - thought that's what I bought.
I like the shape and style. However I had another one years ago that was the best in comparison to this one. I can't find another one like it. It was much stronger thicker and durable. It didn't make impressions in the plastic when I sat in the chair at my desk. Also the nubs on the bottom of the mat don't dig in to the carpet enough to stabilize it's position. Wish I could find another one like the old one. They just don't make um like they use to.
