The Model FCC-MB620-BLK is an unbranded stackable folding office conference chair finished in matte black, designed for flexible, high-use seating environments. Its visual profile features a clean, streamlined silhouette with a sled base, fixed integrated armrests, and a structured horizontal-ribbed mesh back, creating a uniform, professional appearance suited to formal and multi-use spaces alike. When arranged in rows or clustered for events, the chairs maintain a consistent, uncluttered look that complements neutral office and institutional interiors. Built for long-term durability, the chair uses a 1.5mm thick powder-coated matte black steel tube frame, with zinc-plated steel rivet hinges at the X-brace pivot points to support repeated folding and repositioning. The backrest combines horizontal ribbed breathable polyester mesh, rated for 2500 N/50mm tensile strength and 120000 Martindale abrasion cycles, over a 2mm thick molded polypropylene inner support, while the seat uses 50mm thick 45 kg/m³ high-density polyurethane foam topped with 0.8mm thick matte black fabric or PU upholstery. Fixed armrests are constructed from glass-fiber reinforced polypropylene integrated directly with the frame, and non-slip injection-molded PP glide pads form the foot contact points. Functional design supports flexible space management: a side X-brace steel pivot enables a 90-degree flat fold, and folded chairs nest vertically to stack 12 units high for compact storage with minimal footprint. The fixed 10-degree backward tilted back angle delivers consistent lumbar support, with fixed armrests positioned 245mm above the seat to support forearms, while the ribbed mesh back enables continuous airflow for comfort during extended seating. Non-marring glides slide smoothly without scratching hard flooring, and the lightweight sled base allows easy repositioning by lifting the front edge for fast layout changes. The chair supports a 150kg static load, with a 450mm seat height, 465mm usable seat width, 470mm usable seat depth, and overall dimensions of 620 × 620 × 830 mm. This chair is suitable for corporate conference rooms, training and seminar spaces, office reception and waiting areas, temporary event and pop-up work setups, educational institution classrooms, and coworking space shared zones. For procurement, note that each unit ships across 2 cartons, with a packaged gross weight of 23kg per set, requiring 40 minutes of assembly per set. A 20GP container loads 135 sets at 85% space utilization, and the easy-clean upholstery and high-wear materials support frequent use across rotating event schedules.
