Product Description

The 3+1+1 Black Leather Office Reception Sofa Set with Solid Wood Armrests (model OFS-311-BLK-WD01) presents a polished, formal seating solution built for professional settings. Its layout follows a symmetric conversational arrangement, pairing one three-seater bench with two matching single-seat armchairs to support face-to-face interaction between hosts and guests. The design balances a sleek black upholstered body with warm brown polished solid wood armrests that extend down to form front side supports, creating a structured, timeless visual profile suited to refined decor schemes. Construction centers on a durable kiln-dried wood inner frame, reinforced with plywood and treated to resist insect damage, bacterial growth, and corrosion during production. Seating surfaces are upholstered in 1.2mm thick black PU faux leather with an anti-scratch, water-resistant finish, stitched with high-tensile polyester bonded thread in double-stitched panel seams for long-lasting wear. Cushions use one-piece molded high-resilience high-density foam cores topped with a silk floss comfort layer, supported by manganese steel serpentine springs and elastic rubber webbing to retain shape through prolonged use without permanent indentation. Wide solid wood armrests deliver stable arm support and impact-resistant edge protection, while segmented padded backrests provide lumbar support for upright, comfortable waiting postures. Non-marking black polymer glides fixed to each unit’s base prevent scuffing on hard smooth flooring without additional protective pads. The fixed, non-adjustable static seating accommodates five total occupants with no recline or moving mechanisms, streamlining maintenance for high-traffic spaces. It is well suited for executive office reception areas serving leadership teams, corporate waiting rooms handling daily visitor flow, conference lounge breakout zones for small group discussions, formal government and enterprise guest meeting spaces, and small business customer waiting zones, where its compact three-piece configuration fits dedicated reception areas without overcrowding. Procurement teams should note the set ships in two cartons per unit, with a reference assembly time of 40 minutes per set. The frame is rated for 10 years of normal commercial use, with a per-seat static load capacity suited to regular public and workplace use, and the easy-to-clean surface reduces upkeep demands in frequently occupied spaces.
