COLOR, PATTERN AND STYLE
If your furnishings have lots of colors and patterns, you might want a complementary solid color. Or if you want to liven up your space, go for a rug with a more elaborate design.
Keep in mind that low-pile rugs will stand up best in high-traffic areas, whereas plush high-pile rugs might work better in a bedroom or reading nook.
USING MORE THAN ONE RUG
For wide open rooms, several area rugs can help define each space, such as a dining or seating area. You could even create visual interest by layering one or more rugs on top of another.
Whatever arrangement you choose, always use rug pads to extend the life of your rugs.
