The mat is thin and my chair sinks into it as I sit. So much so that it’s hard for the chair to roll after a while. Also the bumps on the bottom that are supposed to keep the mat in place on carpet don’t work. The mat migrates and has to be repositioned every few days. Not happy at all.
Needed this for a new job that is home-based. It doesn't move much so that part is at least correct. But it does indent very easily. I am only 170 pounds and my chair is constantly making huge indents in the plastic while I am sitting on it. They almost completely go away when I move my chair out of the holes. But it is still really annoying.
