Product Description

This contemporary four-seat upholstered sofa presents a sleek, minimalist silhouette defined by cylindrical bolster arms, clean linear proportions, and a slim low-profile black metal frame that balances soft upholstered texture with refined industrial detailing. Its open, streamlined layout avoids visual bulk, keeping sightlines clear across interior spaces, while the warm tan leather upholstery creates a neutral, inviting focal point that coordinates seamlessly with complementary low-profile tan leather ottomans and metal-frame side tables. The sofa is built for long-term durability and everyday use, with an internal load-bearing frame constructed from kiln-dried solid pine and plywood composite, supported by 20mm diameter black powder-coated carbon steel tubing for the outer frame and legs. Seating surfaces are upholstered in 1.4mm thick full-aniline tan top-grain leather, rated to withstand 40000 Martindale rubs for high-traffic use. Seat cushions use high-density polyurethane foam wrapped in soft polyester fiber, supported by sinuous serpentine springs, while back cushions hold a plush blend of down-alternative fiber and shredded foam; cylindrical bolster arms contain a high-density foam core wrapped in matching leather. All legs are fitted with non-marking rubber pads to protect hard flooring and reduce unwanted movement. Fixed linear four-position seating offers stable, consistent support without recline or modular adjustment, with two split continuous seat cushions that are fully reversible to extend upholstery lifespan, four loose upright back cushions, and one angled throw cushion for added comfort. The 120mm open under-seat clearance allows robot vacuum access for easy cleaning, and tool-enabled knock-down assembly via pre-installed threaded inserts cuts setup time to 40 minutes per set, with the product shipped across two cartons. This sofa fits a wide range of spaces, including open-plan residential living rooms, home media rooms, compact urban apartment dining-living zones, modern corporate reception and breakout lounges, and high-traffic boutique hotel lobbies. Procurement teams should note the 85kg net weight, 700kg total frame static load rating, and 150kg per-seat static capacity to confirm alignment with space use requirements, and plan for appropriate delivery handling given the 110kg packaged gross weight across two shipping cartons.
