The title says its cotton - but on arrival the label says wool. 
The rug is very soft and looks great. Feels great on your feelt - not like sisal rugs that are rough AND hard to clean. The color is a bit darker than expected, i was hoping for more of a cream color, but it honestly looks really nice. I liked the 6x9 so well that I ordered another for my entry way. Very happy overall - looks like a much more expensive rug than it was!
