Open Export ToolThe JINSLEI 3-Seat Upholstered Office Reception Sofa, model SF-OF-3S-GRY-001, presents a streamlined, modern silhouette defined by its strght-sided form, matte grey upholstery, and tapered angled black metal legs. The design incorporates three segmented, fixed seat and backrest positions, accented by two contrasting orange throw pillows and integrated padded grey armrest bolsters. Its elevated base creates open visual space, while uniform dark stitching adds a polished, professional finish suited to formal environments. Constructed for consistent commercial use, the sofa features an internal frame of kiln-dried hardwood and plywood composite, with a seat support system combining wide elastic webbing and sinuous spring reinforcement to prevent long-term sagging. Seat cushions use high-resilience polyurethane foam, pred with softer medium-density foam in backrests for balanced comfort and shape retention. The outer upholstery is smooth, non-porous grey PU leather stitched with high-tenacity polyester thread, fitted over foam-wrapped plywood armrest structures. Black powder-coated carbon steel legs terminate in non-slip PP plastic foot caps to protect flooring and reduce movement noise. A matching grey PU fabric slit pocket is integrated into the outer left armrest. Functional detls include non-reclining fixed seating for three users, wide padded armrests for continuous upper body support, and removable orange throw pillows that can be repositioned for targeted lumbar support across any seat. The 130mm floor clearance under the base allows full access for routine cleaning, including standard robotic vacuum use, while the non-porous upholstery supports quick wipe-down cleaning with neutral disinfectants, suitable for high-touch public settings. The sofa’s strght edges also enable side-by-side alignment with matching 1-seat and 2-seat units from the same product line for flexible custom layouts. This model is well suited for a range of commercial and shared residential-adjacent spaces, including corporate lobbies and reception areas, executive office casual meeting zones, open-plan office breakout lounges, co-working facility common areas, and medical clinic wting zones. Its neutral grey finish coordinates with most professional decor schemes, and its high abrasion resistance stands up to consistent high-traffic use. For procurement planning, note that the unit ships with minimal on-site assembly required, delivered in protective commercial furniture packaging optimized for full-contner load efficiency. Buyers should confirm final material specifications, including exact wood species, coating thickness, and upholstery grade, with the supplier prior to final order placement, as reference dimensional and weight values are based on standard product class proportions rather than individual unit measurement. The sofa is designed exclusively for short-term seating use, aligned with standard reception furniture performance expectations. When furnishing larger spaces, pr the model with matching seating units and glass-top coffee tables from the same product line to create cohesive, coordinated wting area sets.
