Why didn't I think of this? Pick the size & fabric -- DIY Memory Foam Rug via the idea room, love this! Another note - memory foam rugs are beneficial to those of us who have brain injuries - no tripping and falling!
Confession: I have an addiction to sourcing Persian and Turkish rugs online. They add warmth, character and sophistication to any room. I think all homes need to incorporate a few vintage or antique pieces and a rug is the perfect way to do just that.
