I love this area rug. The pattern gives the room texture because the shag on the carpet is varying lengths. It does feel like there is some residue on the carpet. It may be something in the warehouse. I don't know. I felt it on my hand as I was fluffing up the pile. If I had a small child I may be concerned ti know what is the residue. Perhaps a vacuum would resolve.  This is not a concern for me so I still give 5 stars.
