Product Description

This unbranded black metal frame upholstered dining armchair, model DIN-ARM-MTL-05BLK, presents a cohesive industrial aesthetic defined by clean lines and intentional structural detailing. Its high back features curved vertical slats formed from bent tubular steel integrated into the main frame, paired with smoothly curved armrests that extend seamlessly from the front legs to create a balanced, streamlined silhouette. The matte black finish of the frame complements the matching matte black faux leather seat upholstery, lending a polished, understated look that aligns with a range of interior design approaches.
The chair’s construction prioritizes long-term durability and comfort. Its core frame uses 25mm diameter tubular steel finished with a black matte powder coating rated to withstand 3000 cycles of abrasion. The seat sits atop a 12mm thick plywood understructure, padded with 45 kg/m³ high-density polyurethane foam with a 60% rebound rate, wrapped in smooth faux leather. The seat measures 510 x 480 mm with 115mm of cushion thickness, supported by a frame that delivers a 510mm seat height, 720mm armrest height, and 540mm backrest height. Welded tubular steel crossbars sit 180mm from the floor to serve as a perimeter footrest, while each leg is capped with non-slip rubber end pads to protect flooring surfaces.
Designed for fixed, non-adjustable stationary seating, the chair supports a recommended static load of 136 kg, with a net weight of 9 kg per unit. It is not stackable, and its smooth, non-porous upholstery and frame finish allow quick, simple wipe-clean maintenance. The chair requires knock-down partial assembly, with an assembly time of 40 minutes per set, packaged across two cartons per unit for transport.
This chair fits seamlessly across both residential and commercial spaces: it works for home dining rooms paired with fixed-height dining tables, casual and themed restaurants, hotel private dining rooms, new-Chinese style tea rooms and lounges, and cafes or bistros requiring durable, easy-care seating. It performs reliably on hardwood, tile, and low-pile carpet surfaces, with a recommended configuration of six chairs per standard rectangular dining table paired with 760mm height tables. Procurement teams should note the 20GP container load capacity of 135 sets at 85% space utilization, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³ per set for logistics planning.
