Leather couches are easy to clean and go with most decorating styles, making them a popular choice for dens and family rooms. Leather couches in shades of brown are most popular for their warmth. The key to decorating is finding a balance of color and patterns that will brighten the couch and complement the rest of your room. Take your time when you're doing this. Buy accessories you love as you find them instead of getting a room's worth of items from one store all at once.
Place a small leather piece on the opposite side of the room. A leather ottoman in a similar brown shade will relate to the leather couch and give the room a sense of balance.
Add throw pillows in a variety of shapes, colors and patterns. Square, rectangular and round pillows add visual interest. Choose light and vibrant colors to brighten the dark brown of the couch. Slate blue, mossy greens, buttery yellows and regal reds complement most shades of brown. Look for floral, stripes and paisleys in the same tones. Pull in colors from the rest of the home. Animal prints are a fun way to inject personality.
Fold a blanket into thirds lengthwise, and drape it over the back of the couch. Choose a blanket in cashmere or silk to achieve a luxurious look.
Flank the couch with light wooden end tables topped with reading lamps. Choose lampshades with natural textures. Rattan or rice paper blend with leather.
Place a few green plants around the room to introduce a jolt of natural color. Ferns require little maintenance and pack a decorative punch.
