This is a great rug pad especially for the money. At first when I laid it out on the floor, I was concerned that the wrinkles would show through on the sisal rug I was putting on top of it would show through. After a day or two of laying out flat and placing the sisal rug on top, no wrinkles. I had to trim off some of the sides of the pad because my sisal was a 9x12 and this pad is a 9x13, a little tough to cut through but not bad. Just shows that this is a quality product that I would purchase again.
