I would pass on the round rug.... Personally I find them odd. I found this rug http://surya.com/Rugs/Pembridge/PBG-1003/ which has both blue and gray in it, which is also inexpensive. You want to find a pattern that is a different scale than the one you have now. In my opinion, I t needs to be a smaller scale than your gray rug. I prefer a rug big enough to have front legs of seating on the rug, and back legs off. Good luck!
