Product Description

Presented under the JINSLEI brand, model EXEC-SOFA-311-BLK-001 is a coordinated executive office leather sofa set comprising one three-seater sofa and two matching single armchairs, designed for formal professional settings. Its visual form features a symmetrical mirrored layout, with the three-seater positioned as the central anchor flanked by evenly aligned single chairs to create a balanced seating group facing a central coffee table. The set uses a cohesive formal aesthetic, with smooth black upholstery paired with walnut-toned polished solid wood trim on arm fronts and perimeter base rls, finished with a three-layer high-gloss scratch-resistant UV-cured PU lacquer that delivers subtle stn resistance. Curved, fully padded armrests sit on carved solid wood block feet attached to a low-profile solid wood plinth base, for a grounded, authoritative presence. The set is built around a kiln-dried solid hardwood frame connected with mortise and tenon joints to meet heavy commercial use standards. Seat support uses 8-gauge sinuous steel springs spaced at regular intervals cross-braced with elastic webbing, layered with 45kg/m³ high-density polyurethane foam seat cushions wrapped in polyester fiber, and 30kg/m³ medium-density foam back cushions. The contoured dual-zone backrest incorporates an integrated lumbar support pad to encourage upright, comfortable posture for extended wts, while wide padded armrests cored with structural solid wood provide generous elbow rest space. Upholstery uses black top-grain leather match or heavy-duty PU leather, finished with reinforced double stitching for long-term wear resilience, and meets minimum abrasion resistance standards for high-traffic areas. Cushions are permanently attached with no removable covers, and the set includes no recline or mobility mechanisms for stable, fixed placement. This fixed configuration seats five people total, making it ideal for executive office reception areas outside C-suite suites, pre-meeting waiting zones adjacent to corporate boardrooms, official government or institutional reception spaces, upscale business hotel executive lounges, and high-end residential home offices or private studies aligned with traditional formal decor. For procurement planning, note that final upholstery grade and internal cushion composition require confirmation from the supplier’s bill of materials prior to purchase. The set ships across multiple cartons with protective packaging, and requires on-site attachment of wood feet and component alignment for installation. A three-year standard commercial warranty covers manufacturing defects for the frame and upholstery, with high-density seat foam engineered to retain shape over regular heavy use. Per-seat static load capacity meets heavy-duty office furniture standards, supporting long-term use in both commercial and select residential applications.
