This rug is exactly what I was looking for and has met my expectations.  I am using it in my mudroom on top of porcelain tile.  It really doesn't slip around (maybe because it is large - I purchased the 3'x5' size) and I didn't experience the edges rolling up that others have mentioned.  The navy blue color is bright and gorgeous and it feels somewhat soft underfoot - not hard and scratchy like the sisal rug I replaced.  I saw this rug online at Nordstrom and was happy to find it here for about $20 less.  :)
