Try putting 2 chairs on an angle in front of your entertainment or wall unit.This way you are using that "wall" for dual purposes and creating depth in your space. I suggest using matching chairs in fabric and structure. Use accents like pillows or a pretty side table to add color. Check out the floor plan above that I snapped at William Sonoma Home that shows this idea. I love how the chairs have accent pillow that match the opposite couch another great way to tie in the color palette of the room.
Place a table in front of a bookcase to create a stylish and very functional idea for bedroom storage. I've posted this idea before and think it's a great way to use your space. (Image via Home Magazine)
If you have a wall of books, you can place your couch in front of the space. The couch will anchor that side of the room and become the center of the focal point of the room. (Image via Thom Filcia)
