Product Description

The Minimalist Off-White Quilted Three-Seater Leather Sofa delivers a streamlined contemporary silhouette defined by clean straight lines, square block armrests, and a low-profile dark plinth base. Grid-quilted stitching across the fixed seat and back cushions adds subtle textural depth without disrupting the minimalist aesthetic, while brushed dark grey metal inlay strips on the armrests offer a quiet, refined accent. Measuring 2600 x 920 x 890 mm overall, the sofa features three evenly segmented seating positions, each with 620 mm of seat width and 620 mm of seat depth, balanced by a 410 mm backrest height above the seat and 630 mm armrest height from the floor, all anchored to a 120 mm tall matte black base for a grounded, uncluttered visual presence. Constructed for long-term regular use, the sofa’s inner load-bearing frame combines kiln-dried solid pine with 18 mm plywood panels, secured with metal corner brackets and wood screws. The seat support system uses 3.8 mm gauge sinuous steel springs paired with 50 mm elastic webbing, topped with high-density polyurethane foam cushions wrapped in 20 mm soft fiber wrap, with seat foam rated at 45 kg/m³ density and 60% rebound rate. Upholstery contact surfaces use 1.4 mm thick smooth full-grain or performance faux leather with 50000 cycles of abrasion resistance, finished with consistent 30 mm stitch seam pitch. The dark plinth base pairs matte black powder-coated steel with an engineered wood substrate, finished with integrated non-slip felt pads to protect flooring, and a black non-woven polypropylene dust cover seals the frame underside. The unit holds a 750 kg overall static load capacity, with a frame rated for 25000 static load cycles, and has a net weight of 90 kg. As a stationary, non-reclining unit, the sofa offers fixed attached seat and back cushions with removable, surface-wipeable covers for straightforward routine cleaning. No full frame assembly is required; users only need to attach the knock-down plinth base, a task that takes 40 minutes per set. The standalone straight unit does not include sectional connection hardware, so it cannot be linked to additional modular pieces. This sofa is well suited as primary seating for open-plan or formal residential living rooms, medium to large urban apartments, modern office lounge and employee break areas, upscale hotel lobby reception zones, and as a featured display piece for contemporary furniture showrooms. It pairs naturally with low-profile stone or metal coffee tables and minimalist shelving to complete a cohesive modern space. For procurement planning, note the product ships as one set across two cartons, with a packaged gross weight of 110 kg and 1.8 m³ packaging volume. The unbranded model carries no modular compatibility, so buyers should confirm space dimensions align with the full 2600 mm length prior to order, and account for basic on-site base attachment during installation setup.
