The Modular Semicircular Two-Tone Sectional Lounge Sofa from JUESHANGDA, model CURV-SEM-3000-BW-CASTER, is a purpose-built public lounge seating solution defined by its smooth curved silhouette and contemporary blue-white two-tone upholstery, featuring a low-back profile that balances unobtrusive sightlines with structured support. Its interchangeable wedge segments lock together via powder-coated steel connecting brackets to form a complete semicircle with a 1580mm inner diameter, sized to accommodate a standard 700mm round lounge coffee table at the open center; segments may also be disconnected for partial curved or linear layouts to fit variable floor plans. Each individual wedge seat offers 1200mm of outer arc width, paired with a 450mm seat height, 700mm seat depth, 120mm thick seat cushion, and 80mm thick backrest cushion, creating seating for six users across the full assembled unit. Its durable construction is engineered for high-traffic public use, starting with an 18mm thick kiln-dried plywood frame stabilized at 10% moisture content for long-term structural integrity. Seat support comes from 4mm sinuous spring webbing spaced 100mm apart beneath cushion layers; seat cushions use 32kg/m³ high-density PU foam topped with a 20mm soft foam layer for balanced support and comfort, with a 60% foam rebound rate, while backrest cushions use 28kg/m³ medium-density PU foam fixed securely to the frame. The 320g/m² 100% polyester commercial woven upholstery features a stain-resistant treatment and 50000 Martindale rub abrasion resistance, with reinforced stitched seams set to 8 stitches per inch, and removable covers to support spot cleaning or targeted panel replacement. Each segment rests on 50mm soft PP swivel casters rated for 35kg per caster, with optional brake locks for fixed positioning; the soft caster material prevents scuffing on hardwood, tile, and vinyl flooring, and enables easy layout reconfiguration without heavy lifting. The inward-facing seating orientation is designed to center group conversation, making the sofa well suited for office reception lobbies, hotel lounge waiting areas, public educational institution common spaces, co-working space breakout zones, healthcare facility waiting areas, and temporary event venue lounge setups. When specifying the product for procurement, note that per-seat static load rating is 120kg, total net weight is 180kg, and the unit ships across two cartons with a total packaging volume of 1.8m³, packaged gross weight of 110kg per item, and an assembly time of 40 minutes per full set.
