Even though the mat fits nicely under my desk the chair leaves impressions and it is hard to roll on the mat. We have a short pile carpet in our den so it is surprising that the mat sinks in so far from the chair rollers. It would be nice if there was a mat the same size with a thicker construction.
My oak desk opening was a little smaller. Had to trim a little (1/2 inch). it fits tight like i wanted. I know when I ordered it i would need to do that.
Went for price my fault. Should have compared product to other ones in store before I made decision. Suggest if your looking for a better quality this isnt it. Already the wheels on my chair are leaving indents. I give it a couple of more weeks at best before i start seeing holes
