Product Description

This 4-seat linear modular channel-tufted black leather sofa, model LS-MOD-4S-BLK-METAL, is an unbranded contemporary modular sectional designed for cohesive, streamlined seating across residential and commercial settings. Visually, it features a low-profile linear form with smooth matte black upholstery finished with precise channel-quilted grid stitching, supported by a seamless matte black metal cantilever sled base that eliminates obstructing central support beams. The 250mm wide padded armrests sit at a balanced 620mm height from the floor, framing a deep, open seating layout that aligns cleanly along long wall placements without blocking cross-space sightlines. Construction centers on a kiln-dried solid hardwood and plywood frame with corner-blocked glued joinery, using primary timber sections sized for lasting structural stability and finished to a recommended 12% moisture content. Seating support comes from interwoven 80mm elastic webbing under seat cushions filled with high-density polyurethane foam wrapped in Dacron batting, rated for 1000kg total static load capacity. Backrests and integrated headrests use variable-density polyurethane foam shaped for targeted lumbar and neck support, while armrests are padded with matching high-density foam over a rigid subframe. The upholstery, available in smooth matte black full-grain or bonded leather, delivers 50,000 cycles of abrasion resistance, with 30mm seam stitch pitch for tailored durability. Matte black powder-coated flat steel sled feet are fitted with non-marking plastic caps to protect floor surfaces, and zinc-plated steel brackets connect individual modules securely. Practical functionality includes a manual ratchet mechanism that adjusts headrests and backrests to three locked recline angles to accommodate varied seating preferences. Zippered, removable cushion covers support straightforward spot cleaning, while the fixed 680mm deep seat, set 450mm from the floor, is optimized for relaxed lounging without movable footrest extensions. Each individual seat offers 750mm of width, with the headrest extending to a full 910mm height at its maximum adjustment. The modular bracket system also allows reconfiguration of sections to suit evolving layout needs. This sofa is well suited for residential open-plan living rooms as primary lounge seating for four adults, modern office reception and waiting areas in executive suites or design studios, high-end hotel lobbies, premium residential media rooms, and open-plan loft spaces. Its matte black low-profile finish complements monochrome, industrial, and minimalist interior schemes. Procurement teams should note the unit ships in two cartons per set, with a 40-minute per-set reference assembly time, 160kg net weight, and 1.8 cubic meter total packaging volume. Removable cushion covers support long-term maintenance, and replacement cushion options are recommended for extended service life.
