This mat is not as thick as the one I replaced which I also purchased at Staples. This mat would probably work on a wooden floor but it's not very good on carpet.
It's my mistake I'm sure but I have fairly new carpet and was new to purchasing this and didn't know what I needed but now I realize I needed something meant for thicker carpeting it slides around a bit underneath me so I have to reposition it every other day or so and my chair barely moves across it. It's my fault I should have bought something more pricey that would be better for the thicker carpet I just didn't know.
