Product Description

The Tufted Black Leather 3-Seat Lounge Sofa (model SOF-BLK-3S-TUF-3000) is an unbranded upholstered linear modular seating piece defined by clean contemporary lounge styling. It features a wide, low-profile form measuring 3000 mm wide, 970 mm deep, and 790 mm tall, with 300 mm wide padded armrests, precisely tufted seat and back cushions, and short matte black composite support feet that leave 50 mm of ground clearance beneath the frame. Each seating position offers 880 mm of width, 680 mm of depth, and a 490 mm seat height, with a 300 mm tall backrest and 180 mm armrest height measured from the seat surface, supporting relaxed, upright lounge posture. The sofa is built on a kiln-dried solid pine frame reinforced with plywood bracing, held to a 12% frame moisture content for stable long-term structure. An 80 mm wide elastic webbing grid forms the core seat support system, topped with cushions tailored for consistent comfort: seat cushions use a 50 kg/m³ high-density foam core wrapped in a white goose down blend, with a 60% foam rebound rate, while back cushions blend high-resilience foam, polyester fiber, and down, and armrests use high-density foam wrapped in soft batting. Upholstery is 1.4 mm thick black top-grain leather treated with a stain-resistant top finish, rated for 50000 abrasion cycles, stitched with high-tenacity polyester thread at 8 stitches per inch. Three throw pillows with printed woven fabric and matching leather covers are included, and the 350 kg total static load capacity supports reliable everyday use. It uses a static non-reclining structure with all-metal under-seat clips to secure its linear three-seat modular layout. Seat and back cushions are fully removable for easy care, and black ABS polymer composite feet attach via tool-fastened screws, with a 40 minute per set assembly time across 2 shipping cartons. The piece fits equally well as primary seating for open-plan residential living rooms and home entertainment spaces, as a complementary piece for luxury apartment lounges aligned with modern minimalist and light luxury interiors, as upscale visitor seating in executive office reception zones, and as premium suite seating in high-end hotels. It pairs ideally with low glass coffee tables and area rugs for a balanced visual layout, with space to comfortably seat three adults for extended periods. Procurement teams should note the 3 year structural warranty, 110 kg packaged gross weight, and 1.8 m³ total packaging volume to plan for delivery, storage, and on-site assembly coordination.
