Not as heavy as other mats and priced so much cheaper. I did not want an oversized one. I was seeking to find one that was just enough to put over a rug that had a chair that would be rolling over it. I was content with the pricing style and material. If you do have a budget for $60-70 to start this is a great choice. Does what the other more expensive ones do but without the hefty price tag.
It took a while to flatten out but once flat it did the job.The one I replaced was also one from Staples but was almost 6 years old. It was time for a new one. Once flat by putting a few heavy books on two edges every thing was ok and I was able to roll around again with my chair at my desk at home.
