This rug smells absolutely terrible.  I have other rugs that have emitted a slight plastic-y smell after being opened (made of the same materials also), but NEVER like this.  It is absolutely disgusting and there is no way it is healthy for you.  The rug looks nice, but the ivory/gray is definitely more blue (in the spots where it looks light gray).  Will have to return it.  Smells absolutely terrible, must be cancerous.
