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.
The price and prompt delivery were excellent. The matt is a bit too thin in that the chair's wheel sink in a bit making it reluctant to move easily. But it is better than trying to move the chair on the carpet. Had I known I probably would have spent more on a thicker matt.
