Product Description

The JUESHANGDA MDA-001-SLB Black Metal Frame Vertical Slat Back Upholstered Dining Armchair blends industrial and modern styling to deliver reliable, visually cohesive seating for both residential and commercial settings. Its visual profile is defined by a sleek open vertical slat back, integrated continuous bent armrests, and a streamlined fixed rigid frame finished in matte black, creating a clean, understated silhouette that complements a wide range of interior design schemes. The chair’s proportions align with standard dining height specifications, with balanced armrest and backrest placement that supports relaxed, upright posture during extended seating. Constructed for long-term durability, the chair uses an 18-gauge carbon steel tubular frame with a scuff-resistant matte black powder coating suitable for indoor commercial use. Solid bent steel vertical slats are welded directly to the top rail and seat frame, with a matching black finish for a unified look. The seat rests on a perforated steel sheet base welded to the frame, topped with a high-density injection-molded polyurethane foam pad upholstered in 1.0mm thick matte black PU faux leather, finished with reinforced stitched perimeter seams. A welded rectangular tubular steel box stretcher connects all four legs to eliminate frame wobble, while injected plastic non-slip replaceable glides are pressed onto each leg end to prevent scratches on hard flooring surfaces. Functionally, the chair delivers consistent support for daily use: the curved vertical metal slats provide targeted mid-back lumbar support, the continuous armrests offer a stable forearm rest, and the fixed rigid seat sits at a standard dining height optimized for use with 760mm tall tables. The wipe-clean PU upholstery allows quick removal of food and drink spills, and the fixed non-stackable frame is designed for permanent table placement rather than frequent reconfiguration. This armchair fits a broad range of spaces: it works as matching seating for residential dining rooms with modern decor, high-traffic seating for cafes, bistros and full-service restaurants, casual seating for office break rooms and staff lunch areas, compact seating for indoor balconies, and guest seating adjacent to standing desks or collaborative tables in open plan workspaces. For procurement planning, note that each unit ships in two cartons, with an assembly time of 40 minutes per set. The packaging and loading specifications make volume ordering straightforward for large commercial fit-outs, and the durable frame construction is suited to environments with consistent daily use.
