I ordered the large 9x12 and it came folded!  Even after putting heavy items on it and leaving it for a couple of days, I could not get the bumps out from being creased. This also could have a lot to do with the thinness of the rug. Wayfair is great when there is an issue with items but I would not recommend purchasing this rug in a large size.  Bump is hard to see in photo but they run throughout the rug.
