We've been using this on our high-pile carpet for six months. It is cracking from the pressure of the chair. It also is not truly designed for high-pile carpets, despite the product description: It migrates around, bumping and damaging the desk legs, and we are constantly having to reposition it. Very poorly constructed.

Edit to add: Wayfair refers claims to the manufacturer. If you order this item, be sure to read the warranty. They will not offer a refund for a defective product like this. I stead, they insist on replacing it and charging a $30 shipping fee. Pay another $30 to bring this junk into my home -- and then pay again for the cost of disposing it? Crazy talk. Do not buy.
