I needed a rug to go under the glass coffee table in front of sofa - it's perfect - great colors with what I already own and ties the room together.  You can't beat it for the cost!  I don't have a mat under it since it's not really to walk on.    

Pros: Great colors, looks more expensive than it was
Cons: the one corner does curl up a little - I'm hoping it will lie down with time
