This 3D model designed in Autodesk Fusion 360 features a functional industrial two-tier bunk bed with integrated bench seating. Constructed from a durable matte black steel frame, it incorporates two slatted sleeping decks made of parallel light wood planks, along with protective top-tier safety guardrails and sturdy structural leg supports. Engineered using 3D parametric sketches, rectangular arrays, profile sweeps, and component assemblies, this versatile CAD model is ideal for metal fabrication blueprints, hostel projects, and 3D interior renders.
