This 3D model designed in Autodesk Fusion 360 features a modern industrial loft armchair with a square light wood seat. Its structural frame is constructed from thick matte black square metal profiles, forming two side-runner leg assemblies that sweep continuously upward to create integrated armrests and a low backrest enclosure. Engineered using 3D parametric sketches, metal profile sweeps, and joint assemblies, this robust design is ideal for furniture manufacturing, blueprints, and 3D renders.
