Amazing buy for the price.  We bought the 11x15 and its the perfect anchor for our living room furniture: couch w/chaise lounge, love seat and coffee table.  The light color is a nice contrast with our dark hard wood floors, but the pattern hides any minor dirt in between vacuums.  We didn't buy a rug pad and have have no regrets, there's really no need for one.  The rug does mat down a bit in high traffic areas, but that's to be expected with any rug.  Just rotate it with the change of seasons and you'll be fine.
