Oh, boy, was I ever happy when I discovered this chair mat. My old mat was literally falling apart and was ugly to boot. I happened to see a round chair mat on the 'net and thought that would work with my corner desk. Of course, it was sold out, so I started a search. The minute I saw this one, I knew it would work. It's clear, fits well with my corner desk, doesn't take up too much room and is just a hundred times better than what I had before. Not cheap compared to the standard mat one sees in the office supply stores, but well worth it.
