Color and size are great but it still slides around on my carpet which is low pile. Also the wheels from my chair indent the mat. I imagine it works best on commercial carpet and/or commercial carpet tile.
I would not recommend this item if the chair on it has wheels. The plastic compresses under the chair wheels and the wheels get stuck in the depressions formed in the mat. I have another mat that I use with a chair without wheels and it works fine as you lift the chair out of the depressions when you move it.
