My carpet plus pad measures 3/4 inch so this mat should work. But after a month it already had semipermanent indentations where the chair wheels tend to be when I'm working. And of course the wheels tend to roll into those indentations making them worse. I had a more rigid mat for some 20 years but it finally cracked. Description indicated that this would work but it's not suitable for anything more than an extremely low-pile carpet. On the positive side it looks good. If I rarely sat in the chair I suspect it would be fine.
Heavy duty mat. Arrived the day after I ordered it and it was delivered flat not rolled up so I could use it right away. Very pleased with this product.
Wanted to protect my beautiful remnant and Staples was the only retailer with the right size look and price. You cant even notice it over the carpet. It was delivered in less than 24 hours!!!!
