Product Description

The Dark Green Channel-Tufted Enclosed Circular Modular Lounge Sofa, model CIR-RNG-3800-DGR, is a distinctive unbranded modular seating solution designed to create defined, inclusive gathering zones across commercial and high-end residential settings. Its closed annular form presents a continuous low-profile silhouette, with consistent vertical channel tufting across all backrest and seat surfaces that lends a tailored, polished visual rhythm. The continuous low backrest frames a central open hollow, allowing unobstructed sightlines across the seating cluster while defining a clear, contained gathering space.
Constructed for long-term heavy use, the sofa’s internal structure relies on a kiln-dried solid hardwood and plywood frame, held together with reinforced polyester stitching at an 8-stitch per inch pitch for seam durability. Seating surfaces are padded with 45D high-density polyurethane foam with a supportive base layer, while backrests use 35D high-resilience polyurethane foam, all wrapped in a matte dark green velvet upholstery. The underside features a non-slip polypropylene dust cover and thick felt floor protection pads, and modular sections lock together via powder-coated steel interlocking brackets. Vertical channel seams prevent internal foam shifting even with regular daily use, preserving the sofa’s crisp structured shape over time. The velvet upholstery is compatible with standard water-based fabric cleaning agents to simplify routine maintenance, and the design supports custom adjustments to outer diameter and upholstery color for commercial project requirements.
The modular assembly connects 16 curved wedge sections to form the full closed ring, with dual-direction orientation that supports both inward-facing seating for intimate group conversation and outward positioning that engages the surrounding space. Designed to rest directly on finished floors without legs or casters, the sofa delivers stable, fixed floor-placed seating for up to 16 people. It ships as knock-down flat-packed sections across two cartons, with foam corner protection to prevent transit damage, and requires roughly 40 minutes of on-site assembly per full set.
This sofa is well-suited for high-traffic commercial spaces including open office break areas, hotel lobby waiting zones, public exhibition and event floors, co-working common areas, and educational campus common rooms, where it acts as a central focal point for casual rest and group interaction. It also serves as a premium statement seating piece for large luxury open-plan residential living areas. Procurement teams should account for required floor space to accommodate the full annular footprint, plan for light on-site assembly, and note that custom size or upholstery options are available for large-scale commercial projects to align with specific spatial or branding requirements.
