Product Description

The JUESHANGDA Curved Modular 4-Seater Upholstered Sofa (model MOD-CURV-SOFA-001) is a low-profile fabric modular sofa defined by its smooth, continuous curved silhouette that forms a wraparound seating arrangement. Its three interlocking modules connect seamlessly via powder-coated steel snap-in brackets, forming a unified crescent shape with oval armless chaise ends on both sides that support relaxed, reclined postures, with no protruding sharp edges across its padded full-perimeter base. The sofa measures 2800 x 1600 x 720 mm overall, with 180 mm thick seat cushions, 160 mm thick back cushions, and 160 mm of floor clearance under its base. The internal load-bearing structure uses kiln-dried solid pine wood framing with primary sections sized 30 × 50 mm held at 12% recommended moisture content, capped with black non-slip EVA rubber contact pads to stabilize placement without floor scuffing. Seat cushions are filled with 40 kg/m³ high-resilience polyurethane foam wrapped in 30g polyester fiber, paired with 28 kg/m³ medium-density foam back cushions wrapped in soft fiber to deliver consistent, supportive comfort. Upholstery uses matte cream short-pile performance velvet rated for 50000 Martindale abrasion cycles, with 120 N tensile strength seam stitching to resist wear from regular use. Each seat position supports 150 kg of static load to safely accommodate 4 adults total, and the 180 mm leg height allows for easy floor cleaning access underneath. The modular design can be reconfigured into straight or alternate curved layouts to adapt to changing spatial needs, while included down-alternative polyester filled throw pillows and a woven cotton-poly blend checkered throw blanket are fully detachable for cleaning or repositioning; the tight velvet upholstery supports spot cleaning with mild upholstery detergent for simple routine maintenance. This sofa fits naturally as a statement seating piece in residential open-plan living rooms aligned with modern and minimalist interior schemes, luxury hotel lobby lounge waiting zones, high-end residential reception foyers, boutique retail VIP consultation lounges, office employee breakout relaxation spaces, and photo studio or event styling sets as a neutral, sculptural prop. For procurement planning, note that each set ships in 2 cartons with a total packaged gross weight of 110 kg, 1.8 m³ packaging volume, and requires 40 minutes of assembly time on site; arrange delivery access to accommodate the 2200×1050×850 mm carton dimensions prior to installation.
