The HUIBANG LS-FL-311formal living room upholstered sofa set features a cohesive 3+1+1 seating configuration paired with a matching coffee table, finished in a dark grey matte palette complemented by dark walnut stned wood accents. The set presents a tailored, classic silhouette with padded rolled armrests, contoured segmented backrests with horizontal recessed detling, and neat, matching dark grey stitched seams across all upholstered surfaces. Each seating unit sits on small dark walnut stned solid wood feet, with fully finished outer arm panels that support flexible custom arrangements, from aligned formal linear layouts to separated seating zones or U-shaped configurations. Seating frames are constructed from kiln-dried solid pine and hardwood plywood, supported by 8-gauge sinuous steel springs with cross bracing for consistent, even support. Seat cushions use high resilience 40 kg/m³ polyurethane foam wrapped in soft polyester fiber, paired with softer 28 kg/m³ contoured foam backrests to deliver upright, comfortable support for formal conversation and relaxed seated activities. The smooth dark grey faux leather upholstery is non-porous, allowing simple spot cleaning with a damp cloth to address spills, while elevated base clearance accommodates standard vacuum access for routine floor cleaning and reduces trapped moisture between frames and flooring. The included coffee table features a dual-level design with a matte lacquered dark walnut veneer top, an open lower storage shelf for accessories and reading materials, and thick solid rubberwood legs with rounded edge details. This set is well suited for formal residential living rooms used for family gatherings and guest reception, executive office reception lounges, professional service waiting areas such as law firms, financial offices and private medical clinics, as well as premium hotel suite and executive lounge common areas. Its neutral dark finish hides light wear from regular use, and its coordinated design pairs seamlessly with dark wood case goods and traditional area rugs. For procurement, note the set ships in multiple cartons, with a gross shipment weight upper bound of 240 kg. On-site assembly for leg installation and unit placement requires two people, with an upper bound assembly time of 60 minutes. The seating frame carries a 3-year structural warranty, and per-seat static load capacity supports standard adult residential and light commercial use, with a total recommended occupancy of five people across the full set. Optional felt pads can be applied to sofa feet to prevent scratching on hard flooring surfaces.
