I searched in stores for a long time for a rug that fit my budget, style, and quality preferences.  Most at the department stores were very thin.  This rug is much thicker than I thought it would be (and as other reviewers said)!.  The white part is raised higher and has a typical plush thick rug pile.  The gray has a flatter loop style.  I am a bit worried that my dog will scratch the loops up, but so far I haven't had any issues!  My family loves it on our feet and it makes the room look so much more modern!
