Two twin beds stack vertically to free floor space while still providing separate sleeping areas in a compact footprint. Solid pine wood and plywood slats create a supportive base under each twin mattress, with 14 slats per tier helping distribute weight up to 330 lbs on the upper bunk and 400 lbs on the lower bunk. Guardrails along the upper bed help keep sleepers contained, while a wide fixed ladder provides a stable climbing path. Open space under the lower bed offers room for light storage and easier cleaning access.
