I ordered this rug after reading many favorable reviews, and I am another one now! This rug arrived in three layers of packaging, so it was very well protected. There are "waves" of lighter and slightly darker blue across the background, so at first it looks like it's wrinkled. But on closer inspection, this is the pattern behind the "dots." At least on my rug, it is not a solid single color behind the dots. But I am okay with it. This rug is a beautiful addition to my space. In this photo you can see my teal fireplace tiles, and the rug color which is a bit more blue. I love it.
