I read the reviews and worried about unraveling.    I actually vacuumed this with the beater bar on and it did fine (you arent supposed to do that).  I was looking for a rug in a bright solid blue with texture.  I thought this looked blue and charcoal online.  The charcoal or darker color is more of a dark green than a gray.  It still works next to gray however.  I like it very much and it is cushy but I always use the rugpads from wayfair.  I never did before but it makes such a difference in how comfortable my rugs are and also absorbs noise in a hardwood floor home.
