The Modern Right-Arm Upholstered Three-Seat Sofa, model SOF-MOD-2100RA, is an unbranded upholstered living room sofa defined by clean, minimalist modern lines and an asymmetric single fixed right-side armrest, with an open left edge for flexible layout arrangement. It sits on slender matte black powder-coated carbon steel legs that deliver a light, elevated visual profile, paired with light gray woven polyester-linen upholstery, and comes with four matching polyester accent throw pillows. Overall dimensions measure 2100 x 800 x 750 mm, with 160 mm tall legs creating 120 mm of under-sofa clearance for open, uncluttered visual flow across floor surfaces. Construction centers on a solid kiln-dried pine internal frame with 30 × 50 mm primary sections held at 12% recommended moisture content, reinforced by an elastic webbing suspension seat base and 8 mm pitch reinforced polyester stitching for durable seam integrity. Seat cushions use 35 kg/m³ high-density polyurethane foam with 180 mm thickness, delivering 45% rebound rate, while back cushions use 160 mm thick soft polyester fiber fill. The upholstery fabric withstands 20000 rub cycles for long-wearing use, and four evenly spaced support legs distribute the sofa’s 68 kg net weight evenly to prevent floor indentation. The unit supports a total static load of 300 kg to accommodate three users comfortably. Practical features include a fixed upright backrest split into three separate cushion sections, four removable throw pillows for adjustable back support, removable seat cushion covers for dry cleaning access, and open under-sofa clearance to accommodate robotic vacuum passage. The open left side can be positioned flush against walls or paired with matching chaise extensions for customized seating layouts. The sofa fits a wide range of spaces: its compact three-seat footprint suits small apartment open-plan living areas and studio multi-use spaces, where it functions as everyday seating or a temporary guest lounge. Its neutral light gray finish complements modern commercial office reception waiting areas, its narrow depth allows placement at the foot of a bedroom bed for extra seating, its asymmetric arm works as a subtle zone divider in open-concept lounge areas, and its durable construction and neutral tone make it ideal for long-term residential rental furnishing packages. For procurement, note the sofa ships in 2 cartons per set, with 40 minutes of assembly time per unit, a packaged gross weight of 110 kg, 1.8 m³ packaging volume, and a 3-year recommended warranty period.
