This mat was supposed to help make a rolling chair easier to roll. It had the opposite effect making it more difficult to move the wheels out of indentations. It isn't worth my time to return it but I would never recommend it to anyone!
Bought this product to protect the carpet and easy to roll the chair. Price is fair for this item. I like transparency of the color so i can see the carpet if it needs to be vacuum. Overall I like the product.
