Open Export ToolThe KERTE Curved Modular Lounge Seating 3-Unit Set, model ML-CURV-01, is a commercial-grade modular office lounge sofa defined by its continuous arc visual form. Composed of three connected curved segments, the set features a striking two-tone upholstery scheme: deep magenta woven polyester fabric covers the seat and base, while dark grey woven polyester fabric adorns the backrest cushions, creating a modern contrast suited to contemporary public spaces. The full-perimeter upholstered plinth base eliminates visible legs, lending a sleek, low-profile silhouette that works equally well agnst walls or as a freestanding island configuration in open room layouts. Constructed with a pine wood and plywood composite internal frame for structural stability, the seating system uses high-density polyurethane foam as its seat core padding, pred with medium-density polyurethane foam backrest cushions topped with fiber wrap for balanced support and comfort. The seat rests on a solid upholstered plinth base that distributes weight evenly across the floor, with interlocking brackets joining each modular segment to form a secure continuous arc. All exterior surfaces are fully fabric-covered, ensuring a polished appearance from every angle. Functionally, the set supports up to 6 people for informal collaborative use, with a curved layout that angles all seats toward a central point to facilitate face-to-face discussion, casual meetings, and relaxed break-time use. The freestanding backrest cushions can be repositioned or removed for cleaning and layout adjustments, while the modular design allows for future expansion with additional matching modules. A 450 mm seat height enables easy sit-down and stand-up access for a broad range of adult users, and the stable plinth base provides reliable tilt resistance during regular use. This seating set is suited for a wide range of commercial and public spaces, including open-plan office break areas, corporate reception lobbies, co-working space common zones, school and university student lounges, exhibition and event lounge zones, and library reading and rest areas. Its durable commercial-grade fabric is engineered for heavy-traffic environments, supporting long-term use with regular mntenance. For procurement planning, the full 3-unit set has a total weight of 120 kg for structural floor load assessment, and ships in knockdown packaging to simplify freight handling. Assembly can be completed by a two-person crew within 60 minutes. Buyers should confirm exact fiber composition, fire ratings, stn resistance performance, timber grade, connection hardware specifications, and warranty terms directly with the supplier, as these detls require official BOM and specification verification to align with project-specific compliance requirements.
