This twin over twin house bunk bed puts a pitched roof over the top deck, turning a shared kids room into a cabin. Guardrails stand 13 in high around all four sides of the upper bunk, which is meant for children 6 years and older. Fourteen wooden slats support an upper mattress up to 6 in thick, and the solid pine frame carries up to 350 lbs A wide entrance and a 3-step ladder let a child climb without help. The 30-in lower bay ships without slats, so it can hold bins, a floor cushion or a reading nook. The open roof frame takes lights or garlands. Assembly is required.
