I was a hesitant to make this purchase, but after reading reviews I took the plunge.  It’s a very attractive rug and we’re very happy with it.  Some reviews said they couldn’t get the rug to lay flat … After laying mine, I expected some settling and smoothing to correct a few creases (the rug comes folded like a burrito).  As I was taking out the packaging material I noticed some writing on the plastic.  It turned out to be instructions.  
1. Unpack, lay flat. 
2. Roll the rug up, let it lay rolled for 24-48 hours. This gets rid of the lumps.  
3. Lay the rug, and vacuum.
