Product Description

The 3+1+1 Black Faux Leather Solid Wood Frame Office Reception Sofa Set, model OFS-WF-BLK-311delivers formal, polished stationary seating tailored for professional commercial environments. Its design follows a symmetric, formal layout pairing one three-seat sofa with two matching single armchairs, unified by cohesive wood trim details that create a refined, authoritative visual presence. The three-seater measures 2100 x 850 x 880 mm, while each single armchair measures 1080 x 770 x 800 mm, with a consistent 450 mm seat height, 580 mm usable seat depth, 620 mm armrest height, and 430 mm backrest height above the seat to support upright, comfortable seated posture. Built for long-term commercial use, the set features a kiln-dried, anti-corrosion treated solid hardwood frame with 40 mm thick members finished in matte reddish-brown lacquer on all exposed trim, arms, and base sections. Upholstery uses 1.2mm thick black PU faux leather with a waterproof, stain-resistant finish, accented by even 2.5 stitches per cm in matching black thread. Seats are supported by 8mm thick plywood decking and sinuous springs, topped with 120 mm thick multi-layer high-density rebound polyurethane foam with a soft top layer and firm support core, rated at 45 kg/m³ density with 60% rebound rate. Backrests use 40mm thick medium-density foam wrapped in polyester fiber, with a contoured curved shape that includes a dedicated mid-back lumbar support zone. Full-length padded arms are trimmed in finished wood and load-rated for seated arm support, while wood legs are fitted with 5mm thick non-slip rubber pads to protect flooring. The fixed stationary set offers no recline, swivel, or fold functions, and supports a maximum of 5 simultaneous users, with a 150 kg per-seat static load capacity and 10-year frame structural service life. Its 50000-cycle abrasion-resistant upholstery wipes clean easily with neutral detergent and a damp cloth for low-maintenance upkeep. Knock-down partial assembly requires 40 minutes per set, with wood frame components bolting directly to pre-upholstered bodies; bulk orders qualify for custom upholstery color and leather grade adjustments. This set is ideally suited for corporate office reception areas, visitor waiting rooms, executive office meeting zones, and business negotiation rooms, and pairs seamlessly with matching wood frame side tables and centrally placed low coffee tables. It performs reliably on polished tile, marble, engineered wood, and low-pile carpet floors, and is not recommended for outdoor use or residential casual high-recline seating. Procurement teams should note the set ships in 2 cartons per unit, with a total net weight of 260 kg, and plan for appropriate receiving and assembly staffing when placing orders for commercial office tenants, government agencies, or business center operations.
