Product Description

The Dark Grey Channel-Tufted Leather 3-Seat Low-Profile Floating Linear Sofa, model SOF-LIN-3ST-090-DG, carries a clean, contemporary minimalist aesthetic defined by its straight, streamlined linear form, low-profile floating platform base, and precise channel tufting across fixed seat and back cushions. Three matching leather, down-blend throw pillows are included to complement the upholstery, balancing structured visual lines with soft, inviting texture. Wide integrated armrests frame the seating area, while the narrow base clearance creates a light, lifted visual presence that avoids visual bulk in open spaces.
Built for long-term durability, the sofa features a kiln-dried solid pine internal frame reinforced with corner-blocked screwed joints, paired with a seat support system of 3.8mm serpentine springs and a 50mm elastic webbing grid. Contact surfaces are upholstered in 1.4mm thick dark grey semi-aniline top-grain cowhide, stitched with high-tensile bonded polyester thread at 8 stitches per inch for consistent seam strength. Seat cushions hold a 60D high-resilience polyurethane foam core topped with 30mm of goose down, while back cushions blend goose down slices with 7D hollow polyester fiber wrap. The floating base uses a powder-coated steel inner frame wrapped in matching leather, fitted with hidden floor glides to protect flooring and prevent unwanted sliding.
The fixed 3-seat layout offers a 105-degree fixed backrest angle and 700mm seat depth, supporting relaxed reclined sitting without additional pillows, while channel tufting maintains uniform cushion shape over time. The upholstery is fixed and non-removable, requiring only surface cleaning. The sofa supports a 408kg total static load, with tested durability metrics including 20,000 Martindale leather abrasion cycles, 10,000 frame joint load cycles, and a 10-year expected service life.
This model suits open-plan modern luxury residential living rooms with panoramic views, boutique hotel lobbies, and luxury office reception spaces, pairing seamlessly with organic-form solid wood coffee tables and warm ambient floor lamps. It is compatible with polished concrete, hardwood, and large-format tile flooring, and fits rooms with a minimum 3.5m clear width across the seating wall. Procurement teams should note the unit ships in 2 cartons, requires 40 minutes of assembly, and uses hidden metal ganging brackets to secure integrated seat modules for stable, long-term placement.
