Bunk Bed Shelf
It seems unfair that the sleeper on the top bunk gets cheated out of a nightstand. After all, where will she put her nighttime water or Harry Potter book? Enter the Bunkpal Bed Shelf. It attaches to the side of most beds and can hold up to 40 pounds (so she can pretty much stack up all of the Harry Potter books).
