Agree with other reviewers that the rug did not lay flat. I felt like someone would for sure trip and fall.   Not sure what return shipping would be on a rug this large, so I felt like I had to keep it and make it work… and I do really Mike the colors and appearance of the rug.  I rolled up the rug the opposite way ( with the right side facing out) and used 8 tight rubber bands to secure it all the way down the length of the roll, and making sure that there was one tight on each end.  I let the rug sit like that for 2 weeks. 
When I unrolled the rug… voilà!  It was flat!.  I did purchase little sticky pads to secure corners and center of each side.  And it is perfectly fine. I have purchased over a dozen rugs from wayfair… this is the first I have had a problem with.  But… it was fixable.
