I have a 4x4 IKEA expedit shelf (which is ~150cm x ~150cm in size) and want to put it 75cm above the floor, so that it lines up with the head-side of a bed. Its back would face the wall, like this:
+-+ |/| +-+ |/| <- Shelf +-+ |/| +-+ |/| +-+ # # #\ #===========================\ <- Bed # # #| ^- What to put here, below the shelf?
On the ASCII-art picture, the shelf is midair. What could I put below the shelf so that it's fixed and won't break up if it is charged with books and stuff?
The wall is labile and I guess it can't secure the shelf all by itself.
