It was half price and I needed some for the office and home. Have only been using for a couple of months - as recommended using on low pile carpeting. It is rated as an ECONOMICAL mat and I expect to get about a year's worth of service. A great value for the price I paid.
Chairmat is way too thin. A chair makes depressions & your stuck & can't roll. Eventually the depressions will disappear. I am only glad I was able to buy two these mats while they were half price. I wouldn' buy another one though.
I have bought several mats like this at the same Staples store over the years. This is the worst one. It was also the cheapest. So no shock there. The last one I bought was the premium one for about double what I paid for this one. It lasted several years and worked much better. This one has had curled edges since day one. Don't buy this product.
