This rug smells like mold and is very old.   I truly believe someone returned it after it had been in their wet garage for an extended period of time- or it sat in a leaky storage facility

I was told by customer service to give it 1-2 weeks 

It’s not the material fumes others speak of- it’s a musty smell

My whole house now smells and it’s been on my floor for 2 days. 

The rug looks clean- it is thinner than I expected. 
Still has fold marks in it
It was folded and shipped in a brown paper wrap 

No idea what is going to transpire here…
