This Modern Geometric Open-Back Upholstered Dining Armchair features a clean, structured silhouette defined by its open geometric back design, with integrated armrests that flow seamlessly from the front legs to the rear frame for a cohesive, streamlined look. The matte black finished frame contrasts neatly against light beige woven polyester upholstery, creating a balanced contemporary aesthetic that suits a wide range of interior palettes. Its fixed four-leg construction uses solid rubberwood for the structural frame, finished with a smooth matte black lacquer, with rounded edge profiles on the integrated armrests for a polished, comfortable feel. The seat and matching back cushions are supported by a 12mm plywood base panel; the seat core uses high-density polyurethane foam wrapped in soft Dacron batting, while the contoured central back panel uses medium-density foam positioned to deliver targeted lumbar support. Both seat and back are covered in durable 0.8mm thick woven polyester fabric with strong abrasion resistance, designed for repeated regular use. Press-fit hard nylon non-marking glides are fitted to the base of each tapered leg to prevent scratches on hard floor surfaces, and zinc-plated steel knock-down connectors simplify assembly, which only requires leg attachment with the included Allen key, taking around 40 minutes per chair. The chair holds an upright 100-degree backrest angle tailored for formal dining postures, with no swivel, caster, or recline functions, and its stain-resistant fabric allows easy spot cleaning with mild detergent. For residential settings, it pairs with standard height dining tables for daily family meals. In commercial spaces, it works for casual and upscale restaurants, high-traffic cafes and bistros, permanent formal banquet hall setups, conference breakout areas, and as desk or dining seating in hotel suites and serviced apartments. Procurement teams and residential buyers should note the fixed, non-stackable design is suited for permanent seating layouts rather than flexible, frequently reconfigured spaces; each chair ships across two cartons, and assembly requires only the included hardware, with no additional specialized tools needed for setup.
