This pad fit our rug perfectly. Some other reviewers said they needed to trim the rug to fit. Our carpet is 6x9 and it was exactly the right size. Perfect thickness for our rug too. The pad adheres to our wood floor well. We notice a slight chemical smell that other reviews have mentioned when we opened the package but after airing it out outside for about an hour , the smell was completely gone.  I highly recommend this rug pad. Good value for the price too.
