This twin over full metal bunk bed is built with a reinforced square-frame structure that delivers enhanced stability and strength. Designed to support up to 400 lbs, the heavy-duty metal frame offers reliable performance for kids, teens, and adults alike. It prioritizes safety with full-length guardrails measuring approximately 4–8 inches high on the upper bunk. The secure guardrail design helps prevent accidental rolling, giving parents and sleepers added peace of mind during every night’s rest. It’s engineered for a quiet, noise-free sleep experience. Plastic buckle connectors firmly lock the slats in place, reducing movement and eliminating squeaks or rattling caused by shifting parts. Its space-saving design makes the most of small rooms and shared spaces. With approximately 12.4 inches of under-bed clearance, the lower area provides convenient storage for seasonal clothing, bedding, or everyday essentials—ideal for bedrooms, dorms, or kid rooms. We recommend assembling the bunk bed with two people for a smoother and safer setup process. With proper installation, the frame delivers long-lasting stability and dependable everyday use.
