For an unexpected headboard, use a decorative element that’s not typical for a bedroom. Consider painted wooden window shutters, a decorative wall divider that can lie flat and be attached to the wall, or an ornate iron panel painted a fun color. Just make sure to place oversized pillows in front of this kind of installation or hang it where your head can’t touch it.
To maximize limited floor space — especially because the bed typically takes up much of this valuable real estate — incorporate flexible furniture that folds up to the wall. You might try a foldout desk that doubles as a makeup table. A wall-mounted pullout shoe organizer in the closet can free up space on the closet floor for a small chest of drawers, adding needed storage.
Look for pieces that have separate legs and just leave them off. One DIY note, if you’re not using a contractor to mount your pieces, definitely consult with one. You want to be sure that your wall can handle the weight, and that you’re using the right support and wall anchors.
We decorate a lot of bedrooms big and small and in lots of budget ranges, but the one item that makes the most difference is bedding. Make sure the bedding and duvet cover fit the bed. My personal taste is to have color and pattern in the bedroom that are soothing and conducive to relaxing.
