I LOVE THIS RUG!  I bought it for my dining room.  I was very happily surprised at how soft it is.  I am using it inside, but it would be great on a deck or patio, since it is an outdoor rug.  I did not buy the rug mat to go under it, and it really doesn’t need it.  I have it directly on my hardwood floors, and it doesn’t move.  The rug laid flat within just a few days.  The direction of the nap does make a difference.  When I first laid it down, it looked very silver, and I could hardly see the pattern.  I turned it around, and it definitely is gray with a warm ivory.  I am so impressed with the quality!  Wayfair is AMAZING with their super fast and FREE shipping!!!!
