I’ve had this rug for a couple weeks now and it’s still not laying flat.  I didn’t want to put rug tape on my tile floor because it will be harder to move for moping the floors but I think it’s the only way to solve this.  The rug is nice looking but cheap feeling.  For the price that isn’t surprising but I wouldn’t be able to get past that if I had purchased it in a bigger size.  I wouldn’t buy it again but for the price I paid I am going to keep it and replace at a later time.
