The Modern Brown Upholstered 3-Piece Living Room Sofa Set, model SOF-LTHR-3PC-BR-001, is a contemporary unbranded upholstered seating group designed for flexible formal and casual lounge use. The set follows a classic conversation layout, comprising one fixed 3-seat sofa and two matching single armchairs, with clean, tailored lines defined by visible, precise stitched seams across all upholstered surfaces. Its smooth rich brown faux leather exterior is accented by integrated stitched panels on wide, padded armrests, elevated by slender polished chrome-plated steel tube legs that create a light, open visual profile with consistent floor clearance. Each seat uses an 18 mm thick engineered plywood internal frame with reinforced corner blocking, built from primary frame sections sized to support long-term structural integrity with recommended 12% moisture content for timber components. Seat support relies on 4 mm thick sinuous spring suspension spaced 80 mm apart, paired with 70 mm wide elastic webbing to prevent sagging. Seat cushions feature 180 mm thick high-density 35 kg/m³ polyurethane foam cores wrapped in 20 mm soft polyester batting, while 160 mm thick back cushions use 28 kg/m³ medium-density foam topped with soft fiber for balanced, supportive comfort. The upholstery is tested to withstand 50000 rub cycles for durable daily use, and the foam delivers a 90% rebound rate to retain shape over time. Each individual seat supports 150 kg of static load, for a total recommended seating capacity of 5 people, while wide padded armrests hold small light items up to 10 kg. All fixed attached cushions are designed for long-term use, with recommended removable and replaceable cushion service options to extend product lifespan. Non-marking plastic glides on all metal legs prevent scratches to hard flooring, and the smooth faux leather surface supports simple wipe-clean maintenance with mild non-abrasive cleaning agents. The set is delivered in two cartons, with legs packed separately for easy attachment to the pre-assembled sofa and chair bodies using included hardware, requiring 40 minutes of assembly per set. This seating group works equally well as the primary seating for open-plan or formal residential living rooms, professional corporate reception lounges and executive waiting areas, and proportional small apartment lounge spaces. It pairs cohesively with low-profile oval coffee tables and neutral area rugs, complementing light neutral wall finishes and light wood or stone flooring tones for a polished, unified look. Procurement teams and buyers should note the total set net weight of 135 kg, packaged gross weight of 110 kg per item, and total packaging volume of 1.8 m³ per item to plan for delivery, storage, and installation logistics appropriately.
