I had previously purchased this runner n the 7 foot length, liked it so much I ordered it in the 5 foot length, for another location. It is amazing the difference just 2 feet can make. The 7 ft just rolled out and layed flat, the 5 ft had many ripples. I guess it just didn't have enough weight to it. I temporarily put some items on top of it, and that seemed to work. I had already ordered good quality carpet pads to place under, (they are to extend the life of the rug). They should also help keep this 5ft runner in place, nice and flat. I am really a fan of Safavieh rugs, so I don't anticipate a problem with this one. Great Offer Stock Customer Service, is wonderful, so if I have a problem...I know I just need to call them. Hope this is helpful!
