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.
