I like the idea of having a simple shelf above the head of my bed. This would work with the idea of the box lights instead of a headboard - they could hang down from the shelf! And that shelf could hold all of my most treasured books!
TreeHugger has shown many ways to hide the bed; most are designed to gain more space. But the Red Nest by Paul Coudamay doesn't; the bed is still there taking up space, but is hidden by the sliding bookcase.
