I bought two of these rugs for my kitchen. The coloring was neutral and the flat rug was perfect for a high traffic space, I absolutely loved them.  Unfortunately, when these arrived, I could smell a horrible smell even before I opened up the packaging.  

I have allowed the rugs to air out for almost a week and have tried to treat them with baking soda to neutralize the smell.  No such luck.  Sadly, I had to throw the rugs out because of the smell.
