Round area rugs are perfect for defining spaces in a room, especially nooks and other small spaces. The circular shape can make an area appear larger, especially when the rug features bright colors and open design patterns. An obvious use for round rugs is for round tables, but there are many other creative uses for this shape. Consider layering a round on top of a conventional rectangle for added character. With a little consideration, you can turn an ordinary room into a cozy invitation.
