Person involved went out of the normal way to provide help in selection and in checking out and then to getting the item out of the store for transportation.
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).
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 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.
