The KETAI OF-RCP-131-WD01 is a formal upholstered office reception sofa set built for structured, upright seating in professional environments. It follows a fixed 1+3+1 layout, with two single armchairs positioned symmetrically on either side of a central three-seat sofa to create a balanced, welcoming seating arrangement. The set features an exposed solid wood base finished in a dark, scratch-resistant lacquer, paired with tailored upholstery for a polished, professional aesthetic that aligns with formal business interiors. Constructed for long-term commercial use, the sofa set’s internal load-bearing frame is built from kiln-dried solid hardwood optimized for structural stability. Seating surfaces are upholstered in 1.5mm thick top-grain cowhide or abrasion-resistant PU, with high-strength polyester stitching applied at a consistent seam pitch for durable seam integrity. Cushions use a layered high-density polyurethane foam core with a high-elastic top layer, supported by a system of S-shaped steel springs and wide nylon webbing for consistent, even support. The exposed frame and solid wood legs feature a hard-wearing 2H lacquer finish to resist surface scratches, while anti-slip pads fitted to the base of each leg protect hard flooring from scuffs and prevent unwanted shifting during use. The fixed 105-degree upright backrest angle supports proper seated posture for extended waiting or casual meeting use, with consistent seat height, depth and width across all seating positions to accommodate a range of users. The set ships in knock-down format for leg and base frame components, with a standard assembly time per set, and includes a 5-year structural warranty for the internal frame. This sofa set is designed first for corporate office reception areas and waiting zones, and also works effectively in executive meeting rooms and business lounge spaces. When procuring this set, buyers should account for the required two-carton delivery footprint, plan for straightforward on-site assembly, and confirm upholstery material selection (top-grain cowhide or abrasion-resistant PU) to align with project durability requirements and aesthetic standards. The fixed, formal layout is best suited to spaces planned for structured guest seating, rather than flexible, reconfigurable multi-use areas.
