This is a great rug!!!  The first thing I noticed when I opened the wrap was that there was absolutely no chemical odor.  When I rolled it out I noticed a few areas that needed to flatten out, which they have done after a couple of days.  I do think it needs a pad, which arrived a few days later.  It is such a beautiful rug and I highly recommend it.  I have hardwood floors throughout my home but felt like the newly redecorated living room needed an area rug and this filled the bill.  Thanks Wayfair for another great product!!!
