I purchased the 8x10 rug and absolutely love it. The quality and look of the rug is noway reflective of the great deal I got on this. If you'r placing a couch or a heavier piece of furniture on top of the rug there is no need to purchase a non-slip mat to put underneath it. I had bought the non-slip mat and rug together and now wish i wouldn't have wasted my money on the mat. Try it in your space first. 

Pros: great quality rug and pattern/ style for the price, no need for a non-slip mat underneath if you're placing furniture on top.
Cons: Only con i can come up with is that without the non-slip mat I've added underneath, it could be a little thin.
