Carve a study nook out of a tight bedroom by building it under a metal twin loft bed equipped with a 40 x 13.5 inch desk and bonus display shelves. A reinforced frame supported by 21 slats carries up to 440 lbs across the upper mattress, while two anti-tipping kits anchor the structure to the wall. Full-length guardrails secure the upper sleeper, and 54 inches of under-bed clearance leaves room for a chair, lamp, and bookshelf.
