Product Description

The Dark Brown Leather 3+1+1 U-Shaped Office Reception Sofa Set presents a polished, formal silhouette structured around a fixed U-shaped layout, anchoring a central three-seater sofa flanked by two symmetric matching single armchairs. Cohesive dark wood trim runs along the lower base, paired with understated matte black metal support legs and rolled, leather-wrapped armrests that reinforce its refined, professional visual profile, while consistent seat and backrest heights across all modules create a unified, orderly appearance suitable for formal commercial settings. Built for sustained high-traffic use, the set features a kiln-dried solid pine internal frame reinforced with silent metal corner brackets at all joints for stable, rattle-free performance. All seating surfaces are upholstered in 1.1mm thick dark brown top-grain cowhide with a stain and scratch resistant finish, accented by high-tenacity polyester stitching set to an 8mm pitch for long-term seam integrity. Seat cushions use 45kg/m³ density high-resilience polyurethane foam supported by 3.8mm high-tensile sinuous steel springs, while back cushions use softer 35kg/m³ density polyurethane foam, both wrapped in matching leather. The lower base uses stained dark solid oak trim, and support feet are constructed from matte black powder-coated steel tube with non-marking pads to protect flooring. The fixed configuration holds an upright 105-degree back angle for comfortable, alert seated posture, with removable split seat and back cushions to simplify routine surface cleaning. Each seat supports a 250kg static load, with seat cyclic durability rated for 100,000 use cycles; the leather upholstery delivers 50,000 Martindale rubs of abrasion resistance, and seat foam retains its shape without permanent deformation for 6 years of regular use, with a 37% resilience rate for consistent comfort. The full set accommodates up to 5 people total. This sofa set is well suited for executive office reception areas, corporate waiting rooms and lounges, boardroom pre-meeting gathering spaces, high-end business negotiation rooms, government and institution guest reception areas, and premium serviced office common areas, where its conservative dark finish and formal styling align with both high-end corporate and official public space aesthetics, and its durable surfaces stand up to frequent commercial visitor traffic. For procurement planning, note the set is delivered knock-down across two cartons, requiring simple leg and base attachment with a 40-minute assembly time per set. Each carton holds 110kg for a total packaged set weight of 260kg, with total packaging volume of 1.8 cubic meters per item, so teams should coordinate appropriate receiving and installation support aligned with these logistics parameters. As an unbranded commercial fixed seating solution, it pairs easily with a range of standard office reception furniture collections for coordinated space design.
