The rug is OK, but I would only pay *** for it on sale. It's not worth more than that. Great Offer Stock has the best deal - other sites have it for ***. Rug is thick, but rough on your kneels and elbows, and a little itchy on exposed skin, If you just walk on, even barefoot, it it's nice and cushy. Like other reviewer said the gray, esp. the light part, is indeed a little green, but I have light green walls, so it matches. The black waves are made of different material, almost like chenille. The lines between different colors of the rug are deep, so the rug appears to be made from pieces. There is a cotton backing. The rug is heavy enough and does not slip on hardwood floors. It's not top of the line, there are other rugs made of finer softer wool. But it's good for *** and heavy daily use. Thank you.
