Although I love the color, shape and design of this rug I have given it 3 stars. When I first put the rug on the floor it stayed nice and flat. However, after a few days it started to bunch up and there is a large bump (for lack of a better word) big enough to trip over, running the length of the rug from the bottom left corner to the top right corner. Since this a large rug (10' x 7') this is a problem and I have been unable to get rid of  the bump.
