Tuck your bed under one of the attic's sloped ceilings. Create a headboard of a mass of pillows piled at the head of your bed to save several inches of space that would otherwise be taken up by a headboard. Place a small nightstand next to your bed to hold books, tissues, an alarm clock, your cell phone and other items.
Choose a thin-profile dresser or armoire that creates extra storage space in height. Place the taller dresser at one end of the attic where the ceiling is highest.
Mount small light fixtures on walls or string twinkle lights across the ceiling. This helps you avoid a space-consuming floor lamp and leaves the surfaces of dressers and bedside tables free for other items that might otherwise become clutter.
Situate a downsized horizontal combination dresser-vanity-storage unit near the foot of your bed. Leave just enough space for you to walk between your bed and the unit.
Choose a large pedestal mirror to stand opposite an attic window. This will make your attic bedroom appear larger and lighter by reflecting daylight from the window.
