I got the 6" round rug for an odd-shaped room and I would call this more of a mat than a rug but it looks cool.  The round one has a significant solid color border all around it.  I got the navy.  It rolled out quite easily and was only a little bumpy at first but is settling nicely.  It looks good with the chairs I also got from Wayfair and it was a good price.  You do need a rug mat.
