LOVE my new rug!  It's gorgeous!  It rolled out nicely with minimal curling on the edges.  I put some heavy things on the corners for a day and it's fine now.  Low odor and what there is smells faintly like a freshly painted room, not bad at all!  I buy polypropylene rugs because they clean so well.  I have 3 dogs and wouldn't you know it, one of them threw up on it the day I got it!  It happened overnight so it dried but still came up with just a bit of Woolite carpet cleaner and a wet rag.  Completely disappeared!  It's really pretty in our bedroom too.
