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).
Have this under my chair at my desk right now. Perfect size. Just needed some dusting on both sides to clean it up from display. Working great. I’ve even vacuumed over it with ease!
Sits on the floor where I put it. Lies flat. Doesn't move. Protects the hardwood. It's everything I wanted it to be. If you want a chair mat that will do all the things a reasonable person expects a chair mat to do then this chair mat is an excellent choice.
the mat is light weight and barely holds the wheels of the chair from indenting in the mat. If this mat is used to protect the carpet it should do that; if it is used to facilitate the wheels of the chair rolling on the carpet - not really.
