I bought this rug with the Deluxe Dual Surface Non-Slip Rug Pad. I put weights on the edges and corners for about 24 hours and they now lay flat.  There were a couple of wrinkles that took a couple of weeks to fully go away but now it's perfect. This is a thin rug, so I would definitely recommend getting a pad to go under it.  The picture is also true to color and is a nice neutral color but not boring - because of the variations in color throughout.  Really liking it in my space. It pulls the living room together.
