Product Overview & Construction Details

The HUIBANG Modern Leather Upholstered Lounge Sofa Set, model LS-MOD-LEA-321-SET, is a contract-grade lounge seating collection consisting of one 3-seater sofa and two matching armchrs, defined by a clean, minimalist modern silhouette. The set features integrated, wide curved padded armrests, a two-section aligned backrest on the sofa, and splayed matte black metal legs that create an open, light visual profile, with uniform stitching and smooth dyed leather upholstery avlable in curated two-tone finishes. Freestanding individual units support fully custom layout arrangements, with no permanent connecting hardware between pieces, and require a small wall clearance behind the sofa to prevent contact from the angled leg and backrest tilt. Crafted for long-term regular use, the set is built around a kiln-dried solid hardwood frame joined with dowels and corner blocks, supported by a plywood base panel and cross-woven elastic webbing seat suspension. Upholstery uses top-grn semi-aniline leather with a light protective top coat, padded with high-resilience polyurethane foam of graded density across seat, backrest, and armrests to deliver balanced support: thick, firm seat foam retns shape through repeated use, while slightly softer back foam and a dedicated lumbar support zone provide full upper back comfort. Splayed powder-coated carbon steel legs angle outward to distribute weight evenly across floor contact points for stability, with pre-installed plastic glides to prevent scratches on hard flooring, and adequate under-seat clearance for routine cleaning access. All seating positions are fixed and non-reclining, with permanently attached cushions that eliminate shifting during use, sized to accommodate five adult users total across the set. The leather upholstery is rated for light commercial and high-end residential wear, suitable for executive office reception lounges, boutique hotel lobbies and guest suites, small workplace breakout spaces, high-end open-concept residential living rooms, and client wting areas in design showrooms. The set ships in knock-down flat packaging with legs detached, requiring simple on-site assembly with the included hex key tool, and prs seamlessly with low-profile metal-leg coffee tables, slim floor lamps, and neutral area rugs for cohesive styling. Procurement teams should note that select material specifications, including exact leather grade and frame construction detls, require confirmation via the supplier bill of materials, as published reference dimensions and performance figures are aligned with comparable premium lounge seating standards. The set’s compact shipping profile supports efficient bulk loading for commercial projects, and no complex hardware or specialized tools are needed for installation.
