The Modern Two-Tone Office Reception Sofa Set (3+1+1 Configuration), model REC-SF-311-MTL-01, is an unbranded contract-grade public seating solution designed for professional visitor-facing spaces. Its visual design features a coordinated two-tone upholstery scheme, with main seating surfaces in smooth PU leather and contrasting matte gray side panels, paired with matte black carbon steel legs and a matching oval coffee table with a matte light gray sintered stone top. The set supports flexible layout arrangements, allowing linear, U-shaped, or split-zone placement to suit different room footprints, with seating pieces resting on stable four-point leg contact. Construction centers on a durable internal frame made of kiln-dried solid hardwood and 15mm plywood, with 1.2mm thick PU leather upholstery stitched with reinforced polyester thread at a consistent 8 stitches per 50mm pitch. Seats and backrests are padded with 45 kg/m³ high-density polyurethane foam with 60% rebound rate, supported by serpentine springs to prevent premature cushion sag, while armrests feature a padded curved wrap-over design built on an internal wood substrate. The 1.5mm wall thickness powder-coated metal legs are fitted with non-marking, non-scratch plastic glides to protect floor surfaces, and the coffee table sits on a brushed stainless steel tubular frame with an oval ring foot. The fixed configuration includes one three-seat sofa and two single armchairs, providing total seating for 5 guests, with a uniform 450mm seat height, 580mm seat depth, 620mm armrest height, and 120mm leg floor clearance across seating pieces, paired with a matching coffee table of proportionate scale for placing reading materials or refreshments. The stain-resistant smooth upholstery can be wiped clean with mild detergent to support routine maintenance in high-traffic areas, and the set ships as knock-down components requiring leg attachment, with a reference assembly time of 40 minutes per set. This sofa set is suitable for corporate office reception lobbies, executive suite waiting areas, conference room break-out spaces, business visitor lounges, professional service waiting rooms, and modern open office collaboration zones, with a neutral finish that coordinates with contemporary interior palettes. Procurement teams should note the set ships in 2 cartons with a packaged volume of 1.8 m³ and packaged gross weight of 110 kg, carries a 5-year warranty, and supports a maximum user weight of 130 kg per seat with a frame durability rated for 50000 static load cycles.
