I was looking for a mat for underneath my desk and my desk chair that would work with very plush carpeting. This particular size and style was a perfect fit.
Its a chair mat. It works just fine. I was hoping it would be a little more resistant to denting from rollers but it's not. But that's OK. It works just fine.
This mat is too "light weight" for my purpose sitting on a fairly plush carpet. It is smooth on both sides so slides around and bunches up where I anchored it under the leg of my desk. My mistake.
