I read the reviews on this rug before buying it myself since I was looking for a rug that was more gray.  I really like the rug, it is soft and fits the space I had.  My rug is more of a green-gray than a blue-gray.  If you are really looking for a blue field, this is not the rug for you. If you are looking for a rug with warm muted tones then this is the rug you are looking for. I would recommend a rug pad.

Pros: Soft underfoot with warm, muted tones.
Cons: Not blue if you are looking for a blue rug. (I was not)
