This mat protects our carpet under the office chair which has 5 wheels. This is our second purchase the first mat lasted several years so the quality is very good.
This particular chair mat is really only good for light duty. I do know weigh very much I have an office chair on rollers; and the rollers mold themselves into the plastic mat. Not easy to move around once I sit. And the carpet that is under the mat is heavy duty indoor/door (not plush at all).
The mat is fairly thin and it will 'dip' from my weight (I'm not over-weight) & chair. It can make rolling the chair on the map a bit of an effort. I don't have plush carpet but the mat still moves a little - not as much as my previous one.
