office chair 3d model

Create a realistic 3D model of a black office visitor chair for a waiting room or meeting room. Overall dimensions: 80 cm high, 48 cm wide and 58 cm deep. Use a matte black tubular metal frame with four fixed legs, slightly angled outward for stability. The chair has no wheels, no height adjustment, no reclining system and no headrest. The seat is black, slightly curved, rectangular with rounded edges, made of smooth solid plastic or firm synthetic material. The backrest is black mesh fabric, not solid plastic, with a thin black frame, rectangular shape, rounded corners and a slight ergonomic curve. Add two fixed black armrests, simple and slightly curved, made of molded black plastic and attached to the metal structure. Style: realistic, clean, functional and low-cost office chair. Do not add chrome parts, cushions or luxury details. Generate one complete centered 3D object with clean geometry, suitable for STL, OBJ or FBX export.
