Product Description

The Modular Circular Curved Sectional Lounge Sofa Set with Accent Chairs, model CIRC-MOD-PUR-01, delivers a modern luxury low-profile lounge seating solution defined by its intentional circular layout. When fully assembled, the set forms a continuous curved ring with a 4200 mm outer footprint, leaving a 2400 mm clear inner conversation area, with two open positions integrated to accommodate matching accent chairs. The set seats 12 total people, supported by individual curved segments and accent chairs arranged to encourage face-to-face interaction. Each seating position offers consistent ergonomic dimensions, with a 450 mm seat height, 550 mm seat depth, and 300 mm backrest height angled 15 degrees from vertical for gentle lumbar support during extended seated conversations. Matching 500 mm throw pillows upholstered in the same purple fabric add soft visual cohesion, while the floor-skimming, legless base eliminates tripping hazards along seating edges for a seamless, polished profile.
Constructed for long-term commercial and residential use, the set features a dual-structure internal frame made of kiln-dried solid hardwood with 1.5 mm cold-rolled steel reinforcement, paired with a 3.8 mm sinuous spring and 50 mm elastic webbing suspension system to prevent cushion sag over time. Seat cores use 45 kg/m³ high-resilience polyurethane foam topped with a 20 mm soft fiber wrap, while backrests use contoured 35 kg/m³ polyurethane foam for targeted support, and armrests are fully upholstered block frames wrapped in matching padding and fabric. The upholstery is a purple matte woven tech fabric with a stain-resistant finish, rated for 50000 Martindale abrasion cycles, that allows simple spot cleaning with mild solvent. Reinforced stitched seams with 8 stitches per 30 mm pitch, non-marking black fabric dust covers on the base, and recycled polyester fiber fill for throw pillows add durable, thoughtful finishing details. Heavy-duty alligator clip connectors secure curved segments together for stable configuration.
This set suits a range of upscale spaces, including hotel lobby reception areas, high-end office lounge and executive breakout zones, luxury open-plan residential living rooms, premium beauty salon waiting areas, exhibition VIP rest zones, and corporate boardroom breakout spaces. For procurement, note that per-seat static weight capacity is 180 kg, and module count, upholstery color, and dimensions can be adjusted per project requirements. Each set ships in 2 cartons, with a 40 minute reference assembly time, and 135 sets fit in a 20GP container at 85% space utilization for efficient large-scale ordering. The unbranded design allows flexible integration with existing interior schemes without conflicting brand markers.
