Other reviewers commented on the chemical smell and I also found that it was really strong.  It did dissipate within a couple of days (would have been better if I could have opened the windows but we were having a real cold spell at the time).  Area rug and mats were purchased for my bedroom and they look very nice in blue.  The design isn't quite as obvious as in the photos but that is fine with me.  The rugs/mats were very tightly bound for shipping and it took a couple of days for them to flatten.  I first laid them upside down and then flipped them and put books on the corners...they are fine now!
