This Twin Over Full Metal Bunk Bed balances space-saving functionality with reliable performance—its heavy-duty steel structure and thoughtful design suit teens, adults, or shared living spaces.Constructed from sturdy metal with electrostatic powder coating, the frame is non-toxic, fade-resistant, and easy to clean. Plastic stoppers secure the slats in place, reducing noise from movement for peaceful sleep. The 38 metal slats provide strong support, with the upper bed featuring surrounding guardrails and the lower bed equipped with thicker legs to enhance safety and stability.With 9.8 inches of under-bed clearance, the design offers extra storage space for boxes, shoes, or bedding, optimizing room organization. No box spring is required—use standard 6” Twin (upper) and 8” Full (lower) mattresses (sold separately) directly on the slats.Assembly is facilitated by detailed instructions and numbered parts, simplifying the setup process. The black metal finish complements modern, industrial, or minimalist decor styles, blending seamlessly with existing furniture.Package Note: Ships in 1 package (dimensions: 80.71”×15.16”×7.89” | weight: 86.42 lbs).
