I ordered this for a rug that I was waiting for on back order, they delayed the shipment from 2/28 to 5/1, I canceled the order for the rug and they now want to charge me $20 to return the rug pad that I can't use because they never shipped the rug. I am not going to use this and it won't work for the new rug I have to purchase; since they couldn't ship the first like promised. BUYER BEWARE!
