The KETAI OFS-CARV-311-TL01 executive office sofa set features a traditional, formal visual identity anchored by a fixed symmetric 3+1+1 conversational layout, designed for structured reception settings. The frame displays intricate carved detailing finished in a rich red-brown polished lacquer, applied across eight coat layers for a smooth, durable surface, while seating surfaces feature diamond tufted top-grain brown cowhide with precise button detailing, creating a refined, authoritative aesthetic aligned with high-end corporate decor. Constructed for long-term heavy use, the sofa set is built on a solid kiln-dried hardwood frame treated for anti-corrosion resistance, backed by a 10-year frame warranty. Contact surfaces use premium top-grain cowhide, while non-contact panels are upholstered in matching brown split leather or faux leather for cohesive visual continuity. Seat and back cores are filled with high-density flame-retardant foam, layered with medium-density foam and silk wadding, supported by a zigzag sinuous spring and elastic webbing system to deliver consistent upright support for extended formal sitting. Each seat position holds a static load capacity of 250 kg, with a total recommended seating capacity of five people across the three-seater and two single-seat armchairs, for a total net weight of 280 kg. The stain-resistant leather surface supports simple wipe-clean maintenance, ideal for high-traffic office environments. Key dimensions include a 2310 mm wide three-seater sofa, 1310 mm wide single armchairs, a 450 mm seat height from the floor, 700 mm single seat depth, 680 mm width per seating position, 510 mm backrest height above the seat, 160 mm armrest width per side, and 620 mm armrest height from the floor. All pieces feature fully fixed, non-reclining, non-folding structures to preserve the formal layout over time. This set is ideally suited for executive office reception areas hosting visitor welcomes and high-level meetings, as well as corporate board waiting zones where traditional premium styling complements senior executive office interiors. For procurement planning, note that each set ships in two cartons, requires 40 minutes of assembly per unit, and carries a packaged gross weight of 110 kg per item with a total packaging volume of 1.8 m³.
