The KERTE OS-SET-002 Modern Leather Office Sofa Set with Glass Coffee Table and Side Table presents a sleek, contemporary aesthetic tailored for both professional and residential settings. The set features a coordinated 1+2+1 seating configuration paired with matching glass-topped occasional tables, unified by a contrasting black and brown upholstery palette accented with polished chrome metalwork. Black PU leather with a smooth semi-gloss finish covers primary seating contact surfaces, including seat cushions and armrest tops, while the upper backrest section incorporates brown matte PU leather as a visual accent. Curved chrome-plated steel legs support all seating pieces, while square polished chrome tube frames form the structure of the coffee and side tables, which are finished with black tempered glass surfaces and rounded edges. Constructed with a plywood internal frame reinforced with solid wood, the seating units are filled with high-density polyurethane foam designed to retain shape and provide consistent support. The table tops and lower shelves are made of tempered glass, which breaks into small granular fragments to reduce injury risk. Smooth PU leather upholstery and glass surfaces allow for straightforward cleaning with standard or neutral cleaning agents, making the set well-suited for high-traffic areas. The curved metal legs have flat, wide base contact areas that distribute weight evenly to minimize floor scratching, and they are compatible with optional self-adhesive non-slip pads for hard flooring surfaces. Functionally, the modular design of the four independent seating pieces enables flexible layout arrangements, including linear, L-shaped, parallel, or distributed configurations to fit varying space dimensions. The coffee table includes a dual-tier storage design, with the upper surface holding drinks and decorative items and the lower shelf storing books, remote controls, or dly necessities. The side table provides two-tier glass surface space sized for placement next to armchairs, holding personal items, beverages, or reading materials during visits or relaxation. The set supports casual 4-person gatherings, with the coffee table serving as a central surface for documents and refreshments. This sofa set is appropriate for a wide range of commercial and residential spaces. In commercial environments, it works well in corporate office reception areas, executive office lounges, small meeting and discussion zones, hotel and serviced apartment lobbies, and co-working space common areas. For residential use, it serves as main seating in apartment and house living rooms, fits compact guest reception areas in small to medium living spaces, and defines lounge zones in modern open-plan studio apartments while mntning visual lightness. Procurement considerations include the knock-down structure of the set, which ships in multiple cartons with legs detached to reduce shipping volume. Assembly requires attaching legs to seating units and assembling table frames, with basic tools included. Freight costs can be using the total shipment volume and gross weight of the full set, and bulk order quantities can be calculated based on standard contner loading efficiency.
