When I opened the rugs they gave off a horrible chemical smell! I am on the fourth day now and have had to have the windows open and fans running but the smell is still there. Kind of rough since it's only 30* outside. I'm wearing my coat and gloves all day in the house. I do love the look of these rugs but not sure I will be able to keep them if the smell doesn't go away. These rugs are beautiful and the match my rooms perfectly. I am super disappointed in the smell though. Although they are not as thick, just as others have said, but quite soft and comfortable just the same.
