Product Description

The Modern Brown Leather Four-Seater Sofa with Horizontal Channel Stitching (model FS-LTHR-CHAN-3400) is an unbranded stationary upholstered seating piece defined by a clean, low-profile blocky silhouette aligned with contemporary and minimalist design languages. Its form features integrated angular padded armrests and evenly spaced horizontal channel stitching across fixed upright backrest panels, paired with short powder-coated black carbon steel support legs that create a subtle, grounded elevation. Four throw cushions are included with the piece: three with brown leather covers and one with a textured light gray woven fabric cover, all filled with a down blend, to add subtle tonal and textural contrast to the rich brown leather upholstery. Overall dimensions measure 3400 x 1080 x 880 mm, with a 510 mm seat height from the floor, 780 mm width per equal seat position, 660 mm seat depth, 140 mm armrest height above the seat surface, 370 mm backrest height above the seat, 200 mm armrest width, and 80 mm leg height. The sofa’s internal load-bearing frame is constructed from kiln-dried hardwood with moisture content at or below 15 percent, fitted with a sinuous steel spring and interwoven polypropylene webbing seat suspension system for consistent support. Contact surfaces are upholstered in 1.4 mm thick top-grain brown cowhide, while side and back non-contact surfaces use matching split brown leather. Seat cushions hold 150 mm thick, 45 kg/m³ high-density polyurethane foam wrapped in Dacron, and backrests use 120 mm thick, 35 kg/m³ medium-density polyurethane foam to deliver medium-firm lumbar support; cushion cores are fixed and not removable, while the smooth leather surface enables wipe-clean spill resistance. The unit supports a total static load of 545 kg, with a net weight of 130 kg. The short elevated leg design leaves clear space beneath the frame for easy floor cleaning access, and four equal stationary seat positions accommodate comfortable residential lounging, while included removable throw cushions allow adjustable neck and lumbar support for personalized comfort. The sofa is well suited for use as the primary seating in residential open-plan living rooms, with four-person capacity to host family and guests. Its formal leather finish also fits upscale executive lounge reception areas, its long linear form functions effectively as room-divider seating in open-plan lofts or apartments, and its deep seat profile supports relaxed lounging in home media rooms. It pairs best with a 400 mm tall low-profile coffee table positioned 400 mm in front for accessible surface space, and complements modern minimalist and Italian light luxury interior schemes. For procurement, note the unit ships as one set across two cartons, with a packaged gross weight of 110 kg per item, packaging volume of 1.8 m³, maximum carton dimension of 2200 mm, and a 40-minute per-set reference assembly time. Procurement teams should allocate appropriate receiving, handling, and installation resources aligned with these logistics parameters, and confirm placement dimensions to ensure the linear form fits intended floor plans prior to ordering.
