This is probably the best purchase I have ever made on Overstock. This rug is absolutely beautiful, and made very well. It doesn't list how many knots per square inch, but I would guess 125-135. The rug is HEAVY! The weight is over 100 lbs. It is almost impossible to maneuver alone, especially when trying to move it on top of the rug pad I bought to go under it.I was concerned about buying a rug and trusting the colors shown on the monitor, but all the other reviews were very helpful and correct in their color descriptions. The black is true black, and the burgundy is dark and rich.If it helps, the narrow color at the edge is black, then the next band is rust, (which isn't shown in the picture), next is sage, then burgundy, sage, rust, then the black center.The rug has a tag on it the says it is A Safavieh, Traditions Collection, Design TD602C. 100% Wool, with silk.You can't go wrong with the purchase, and the price is amazing for the quality.
