QILISEN Dark Grey Leather Office Reception Lounge Sofa Set (model OF-RCP-SLED-DG-113) presents a polished, formal seating solution for high-use professional spaces, configured in a 1+1+3 layout designed for classic U-shaped arrangement. The set includes one three-seat sofa and two matching single armchairs, all anchored by sleek powder-coated dark grey steel sled bases that create a streamlined, modern silhouette aligned with contemporary commercial design standards. The cohesive dark grey upholstery carries a uniform, refined finish, with visible reinforced stitching that adds subtle structural detail while supporting long-term durability. Crafted for consistent heavy use, the set features a kiln-dried solid hardwood core reinforced with multi-layer plywood panels, supported by a seat system of heavy-gauge serpentine springs tied with steel wire and polypropylene webbing. Seat cushions are filled with high-density polyurethane foam wrapped in a soft dacron layer, paired with medium-density contoured backrests that deliver built-in lumbar support. The outer upholstery uses 1.5mm thick dark grey top-grain leather match, treated with a stain-resistant, water-repellent top coating, with abrasion resistance rated for extended commercial use. Sled bases are fitted with non-marking rubber glides to protect hard flooring surfaces, while even weight distribution across the base design reduces tipping risk on smooth hard floors. The fixed, non-reclining structure has no tilt, swivel or adjustable mechanisms, built for stable static seating suited to short to medium wait times. The smooth upholstery surface allows quick wipe cleaning with standard mild upholstery cleaners, and the set supports a maximum of 5 occupants across the three pieces. More than 60 custom leather or PU color options are available for OEM contract orders to align with specific interior design schemes. This sofa set is well suited for corporate reception lobbies, where the U-shaped layout supports face-to-face guest waiting and check-in seating, as well as executive office waiting areas, where its minimalist dark grey aesthetic complements premium professional interiors. It also fits co-working facility lounge zones, public institution visitor areas, and small informal meeting spaces, with commercial-grade construction built to withstand high daily foot traffic. For procurement planning, note the set ships in two cartons, with a reference assembly time of 40 minutes per set. Buyers should account for the recommended U-layout total footprint when allocating space, and confirm custom color lead times for orders requesting alternative upholstery finishes to match existing interior palettes.
