The item description claimed the studs on the back would keep it in place on the carpet. Wrong. Every time I rolled the chair across it the mat shifted. When I sat in the chair for any significant length of time the chair wheels left dents in the plastic that made it difficult to roll - and I weight less than 140 pounds. This mat is very poor quality.
I had one of these mats before and it gave me several years of good service. When it was time to replace it I looked up the product number and reordered. To my surprise the plastic is now much softer. Instead of rolling over it smoothly as I did before I find my chair wheels create ruts in the softer plastic and I have to lift the desk chair in order to move it. I will not buy this again
I liked to say it works great but the bad part about it is that it keeps moving on the carpet. It should have pointed grippers on it instead of square grippers to keep it in place. It is very irritating to have to keep moving it back in place.

The chair mat remains in place. The chair rolls easily and makes a slight dent in the mat. However the dent disappears after a short while when the chair is moved to another position.
