Purchased this for my home office. Even though it did not come recommended for thick home carpet surfaces it works fine. In my opinion there's no need to spend extra money for the mat that is reinforced for carpets unless you expect to have heavy traffic in this area.
The strong "chemical" smell nearly cost this product its 5 star rating -- After three days in a well ventilated storeroom it "earned" its way back into my office. A great carpet protector despite my 220 lb body weight.
I purchased this for my home office and did not want to spend much. I am using it to protect my carpet but it gets a little lumpy. I weigh 150 so maybe the thickness is not adequate for this weight. For the price it is okay. In the future I would spend a little more for more quality.
