I ordered the 11' x 15'.  This is a large rug for a very affordable price.  It is very thin (but I expected that) and the colors are spot on to the photos on the website.  I love the soft variety of color in the rug which help it to blend well in our family room.  I didn't order a rug pad for underneath only because I wanted my Rumba to be able to make it under the sofa and clearance was barely possible already.  But, if that wasn't an issue I would recommend purchasing a rug pad for underneath.  This rug did have wrinkles but slowly they are working themselves out.
