Product Description

The JUESHANGDA Modular Curved Armless Caterpillar Sectional Sofa, model CURV-CAT-5MOD-4000, is a low-profile lounge seating solution defined by its smooth, continuous arc form and unobstructed, armless open layout. Its five interlocking segments are designed to be rearranged into custom curved configurations, with a sculptural, minimalist silhouette that serves as a deliberate visual focal point in open settings. The sofa measures 4000 x 1750 x 600 mm overall, with a 430 mm seat height, 800 mm seat width and depth per module, 300 mm bolster backrest height, and 30 mm base ground clearance; it includes short caterpillar sections of 1600 mm and long caterpillar sections of 2400 mm, and seats 5 adults comfortably. Constructed for long-term durability, the sofa features a solid kiln-dried hardwood internal frame with primary sections measuring 30 x 50 mm and a recommended 12% moisture content, supported by hidden low-profile 20 mm thick carbon steel legs. The outer upholstery is off-white textured bouclé teddy polyester fabric treated with a stain-resistant, spot-cleanable finish rated for 40000 Martindale rubs of abrasion resistance. Seat cores use 40 kg/m³ high-density slow-rebound polyurethane foam tested for 6000 compression cycles, while bolster backrests are filled with matching 40 kg/m³ high-resilience foam. Zinc-plated steel interlocking clips secure modules together, and an anti-slip silicone dot non-woven fabric lines the base to protect hard flooring and prevent unwanted shifting. The entire unit weighs 180 kg net, with a 750 kg total static load capacity, and foam reaches full expansion 72 hours after unpacking. Practical design features include flexible multi-position access enabled by the armless layout, ultra-low seat positioning for relaxed floor-adjacent lounging, vacuum-compatible compressed shipping to reduce transport volume, simple spot cleaning with mild detergent and a damp cloth to avoid discoloration, and support for two removable, replaceable cushion service configurations. The sofa is well suited for residential open-plan living rooms as a statement lounge piece, home theaters for extended media viewing, modern office break and informal meeting zones, hotel and boutique lobbies to create welcoming conversation nooks, high-end interior showrooms as a sculptural display piece, and temporary open event spaces that require reconfigurable seating. For procurement, note that each set ships in 2 cartons with a total packaged gross weight of 110 kg per item, 1.8 m³ packaging volume, and requires 40 minutes of assembly time per unit.
