Terrible Quality!
I have just received this rug and it is creased like paper.  I have left it over night and it is still really wavey and turned up at the ends. I have put heavy things on the corners but it still curls up.  I will give it another day and if it hasn't settled down I will return it.  
The pattern is really nice.
I've bought a few rugs from Wayfair and never had this problem before.
