I purchased a plastic Chair Mat from Staples to put on Plush Carpet in my home office. It's very sturdy and because it's transparent you don't even notice it. I highly recommend it.
Just what I was looking for. I have plush carpet and the other chair mats for "medium pile" were not cutting it. I would just sink down into the mat. This one is a perfect size super thick and smooth rolling. And made in the USA with fast shipping. Highly recommend.
Purchased for my home office thinking why spend more money than necessary. Having been in the commercial office environment for 20 yrs. I purchased and used many many chair mats and this one doesn't seem to meet the standards I am looking for. It seems to be to thin and the wheel dimples stay for quite awhile. Should have bought a more expensive one.
