It has a really bad smell.  You cannot keep it inside because it has such a strong odor.  I tried baking soda,  air out in the sun, in the shade, , disinfection spray., etc.  Nothing worked.  It’s probably wet when it was stored before shipping.  After trying a couple of weeks, it still smelled bad so I ordered a replacement.  However the replacement has the same bad smell.  I guess the whole warehouse is not controlled properly.  I need to pay shipping to return both items so I was stuck with a smelly rug and a huge job of wrapping up the replacement and taking to UPS.  I don’t even know how.  Very dissatisfied.
