I had a chair mat at my desk that was meant for a hardwood floor. When I moved I had carpet. The new mat is much better with little prongs to hold in the carpet. I am enjoying it very much
The chair mat was delivered flat which was good. It is fairly thin so light duty. Wheels from the office chair is already leaving indentions on the mat. I don't expect it will take long for those indentions to be permanent and make rolling the chair on the mat difficult. So I expect to replace it within a year which isn't such a big deal at $28.00 for the mat. However a heavier duty thicker/more rigid mat might suit you better … I hope this helps with your decision to purchase this product. Wouldn't want you to go through the hassle of returning it if you need something "more."
