Area rugs have the potential to make a profound impact on any space. An area rug can simultaneously break up the pattern or color of the carpet/flooring, while also creating a focal point for people to gather.
But whether the impact of that area rug is positive or not so much depends entirely on your ability to choose the rug wisely. Get this wrong and a rug can simply make your space look busy. It might get in the way and prevent you from moving your furniture. It might even be a tripping hazard!
