This is a very pretty rug.  I ordered it in the 9 by 12 size and have had it for 8 days.  Shipping was very fast and problem-free.  The rug arrived in perfect condition.  Vacuuming it with a power head is fine.  The reason I gave it 4 stars is because it is still off-gassing and the edges are still curled up.  I have placed books and other heavy objects on the edges which help only temporarily.  I suspect/hope that over time the edges will relax and the smell will dissipate.  It is still very hot here so opening the windows isn’t an option yet.
