Mat woulld be much better if made of thicker more ridged plastic. Don't like the dimples in the mat that make it hard to roll around or change position.
It required three men and a small boy to lay it flat. Within days this chair mat developed "dimples" where the chair wheels were located. I tried to go cheap and should have bought the more expensive rigid model.
If you need an inexpensive desk mat for your home office this is the one to get if you have low pile carpeting. I would not recommend it for a business office with heavy use.
Nice mat needed if you have a weight on the chair and it is over a rug. I have the other less thick which my wife now has. She weighs less. Great buy for the money.
