I bought this because it said it'd work well with carpet. No. It does not. It slides around when I move my chair at all. The underside is textured, but barely. There isn't anything to grip and keep it in place. I have spent more time readjusting this thing than I care to admit. Also, the wheels leave divots in the plastic if you sit in one place for too long, and you have to push yourself out of them. I expected something much heavier and better suited to high pile carpet. (As it says in the product name) I finally gave up and ordered a different mat from another retailer this week. Now to figure out if I can recycle this thing.
