Open Export ToolThe KERTE OFF-SOFA-311-LW Modern 5-Seater Office Reception Sofa Set features a streamlined, contemporary two-tone visual profile, delivered as separate modular units: one three-seater sofa, two matching single armchrs, and a coordinating coffee table. The set supports flexible arrangement, including a classic U-shaped configuration ideal for face-to-face interaction, with squared clean armrest edges, grid-tufted back cushions, and a striking contrast between lime green seat and back upholstery, semi-matte white outer frame and armrest cladding, and polished chrome metal hardware for legs and table framing. For construction, seating units are built around a reinforced multilayer hardwood plywood internal frame, upholstered in smooth artificial leather with high-strength, color-matched polyester stitching. Seat and back cushions use high-resilience polyurethane foam of graded densities—firmer foam for seats to balance comfort and long-term shape retention, slightly softer foam for back support—permanently fixed to the frame to prevent shifting during regular use. Each seating unit sits on short cylindrical chrome-plated mild steel legs fitted with non-marking floor protection glides. The included coffee table features a chrome-plated stnless steel X-braced frame with two tiers of thick black tempered glass with polished edges, forming an upper display surface and lower open storage shelf. A sealed moisture-resistant hardboard panel forms the under-seat base to guard agnst warping. Practical design elements support short-stay public seating use: a slightly upright fixed back angle suited for brief visitor wts, evenly distributed grid tufting for consistent lumbar support, full-depth wide padded armrests for stable elbow support, and smooth non-porous upholstery that wipes clean easily with standard disinfectants. The fixed cushion design reduces routine mntenance needs in high-turnover spaces, while integrated floor glides prevent scuffs and scratches on polished tile and hardwood flooring. The two-tier coffee table holds refreshments and reading materials on its top surface, with the lower shelf keeping magazines or small accessories organized. The set is well-suited for a range of commercial spaces, including corporate reception lobbies, co-working common lounges, small business customer wting rooms, showroom lounge zones, and internal staff breakout areas. Its compact, low-profile frame does not block sightlines in smaller entry spaces, while the bright modern color palette acts as a polished focal point in client-facing environments, supporting a professional welcoming tone for visiting guests. For procurement planning, note that on-site assembly requires basic hand tools, with two workers able to complete leg attachment and coffee table assembly in one hour. The set ships in five protective cartons with foam wrapping, corner protection, and heavy-duty corrugated outers to reduce transit damage risk. Confirm specific material grades, safety documentation, and cushion replacement options with suppliers prior to final purchase, as some construction specifications require formal bill of materials validation. The durable upholstery is rated for medium-traffic use, making it appropriate for spaces with regular dly visitor turnover.
