Purchase a deep gray or black comforter and black, gray and white pillowcases. Pile up decorative pillows in those colors at the head of the bed to add lightness and variety.
Place black wood side tables on each side of the bed. Center the bed against a wall and measure the space on each side of the bed to buy the right sized side tables.
Top side tables with chrome accented table lamps and silver picture frames housing black and white or hand-colored images.
Hang an extra-large black and white or hand-painted art piece over the bed. This will complement the blacks and grays in the room and define the space in lieu of a headboard.
Lay a sheepskin area rug at the foot of the bed to add a new texture and luxury to the room.
Add a pop of color in your gray space with one bright colored pillow. If your artwork is a hand-colored black and white print, use that to determine what color to add to the space.
Hang white sheers from the windows to add light and privacy as well as a visual softness to the space.
Use a black wood chest of drawers to hold clothing. Fit the dresser with silver drawer pulls and accessorize to match the bedside tables.
