This rug is absolutely gorgeous!  Ours has the large spiral in the center, and we love the sense of movement to draw in the conversation circle.  It’s true to size with vibrant colors and a cozy shag.  This rolled out flat and filled the space perfectly.  Slight new carpet smell lingers a few weeks,  but i think of it like “new car smell” -). A bit of Febreeze is enough if it bothers you, but it does eventually dissipate.  
This rug feels great underfoot.  I’m using it on a laminate floor in the larger 9’ x 12’ size and have placed sofa and chair legs on it.  Its quite comfy even without a rug pad, but if you are using a smaller size and not having furniture to anchor its location, i would use a rug pad.  We are very pleased with this purchase.
