For the most part I am very pleased with this carpet. It is constructed well. It came rolled and only took 2 days to relax and lay flat. I helped this along by putting  something heavy on the edges and corners. I am using a rug mat underneath and this does add a soft padded cushion underlay. My only complaint with this rug is that it attracts lint every time I walk on it with shoes, that it leaves visible dust and small particles on the black color.
