Purchased for my home office on medium pile carpet. After 2 days of use there's cracks starting under the wheels of my chair. I'm under 150lbs and use about 6 hours a day. Quality is definitely not worth it.
This chair mat was easy to transport. Once I had it home there was no uncurling it started using it immediately. I use it in my sewing room it works great for me. I highly recommend this mat.
It is an under the computer chair mat. The purpose was to replace an old mat that had been détented by a similar chair. I am very disappointed that the new one dents worse than the old one. Wherever you place the chair it dents the pad. In order to move you have to get up and move the chair. Very disappointed.
