I have two chairmats so I can get from one desk to the other. I like the fact that it protects my carpet from snags and wear. I would recommend everyone use one to save wear and tear on carpeting. I am very pleased with the mat and how it holds up.
This mat was just too soft. The chair wheels sank into it and I couldn't roll without a good push. Mine was sitting on low-pile carpet and I am an average-sized woman. I had to return it.
