I like the pattern on this grey/black rug, but am having a hard time to get it to lay flat.    Think it must have been rolled up a long time.    Put it under the living room rug for a couple of days, but no luck, now have it on the floor with two pieces of heavy furniture on either end to try and stretch it flat.    If that doesn't work will put it in the walk-in closet, will keep my feet warm when I go in there barefoot.   Where there's a will there's a way, as 'they' say.
