The 3+1+1 Dark Brown Leather Executive Office Reception Sofa Set, model OFS-311-WA-DBR, is an unbranded structured upholstered fixed seating set designed for formal professional environments. Its visual profile features a boxy, tight-upholstered frame accented by polished stained solid wood armrest caps and block legs, finished in a rich dark brown leather palette that pairs seamlessly with traditional wood office furnishings. The set is arranged in a conversational 3+1+1 layout, comprising one three-seat sofa and two single-seat armchairs, with split seat and back cushions that lend a tailored, orderly appearance suited to structured professional settings. Constructed for long-term commercial use, the set is built on a kiln-dried solid rubber wood internal frame, finished with a UV-cured clear lacquer to protect wood surfaces. Upholstery uses dark brown top-grain split leather, stitched with high-tenacity polyester matching thread at a consistent, durable stitch pitch. Seat cushions hold high-density polyurethane foam wrapped in polyester, supported by wide elastic webbing, while back cushions use medium-density polyurethane foam for balanced support. Armrest caps are crafted from polished stained solid wood, and solid wood block feet are fitted with non-marking plastic glides to protect floor surfaces. All backrests are fixed in an upright, non-reclining position to support proper posture during formal discussions and extended waiting periods. The leather surface wipes clean easily with standard gentle cleaning products, though care requires avoiding harsh abrasives and prolonged direct sunlight to preserve material integrity. Assembly is minimal, limited only to attaching the knock-down legs, as all main sofa and chair bodies arrive pre-upholstered, with a reference assembly time of 40 minutes per set shipped across two cartons. Custom upholstery and wood finish options are available for projects requiring coordinated design alignment. This set is ideally suited for executive office reception areas, corporate lobby waiting zones, formal business negotiation rooms, and leadership office meeting spaces, where its conservative professional finish complements existing dark wood office furniture. The 3+1+1 layout comfortably accommodates small groups of visiting guests, corporate staff, and meeting attendees, and pairs naturally with a matching dark wood coffee table to create a cohesive reception arrangement. When planning procurement, note that the set carries a total net weight of 260 kg, with a per-seat static load capacity of 150 kg, and select add-on pieces as needed to complete planned space layouts.
