Product Description

The Youwei L-Shaped Right-Facing Leather Upholstered Sectional Sofa, model SEC-L4R-CM-BKLG, is a residential seating piece defined by clean, modern minimalist lines. Its right-hand facing configuration attaches a chaise lounge to a three-seat main sofa, creating a streamlined, open layout that anchors seating zones without visual clutter. The design features loose, reversible seat and back cushions, matching top-grain leather throw pillow covers, and stitched rolled armrest edges, with a structured silhouette that aligns with contemporary and light luxury interior aesthetics. Built for lasting daily use, the sofa uses a kiln-dried solid hardwood and plywood inner frame, with primary timber sections sized to meet 30×50 mm dimensions at recommended 12% moisture content. Seat and back surfaces are upholstered in top-grain cowhide leather, with 180mm thick seat cushions cored in high-density 45 kg/m³ polyurethane foam wrapped in a down blend, and 160mm thick back cushions filled with 35 kg/m³ medium-density polyurethane foam and fiber for balanced comfort. The 160mm tall legs are constructed from 1.5mm thick powder-coated carbon steel, fitted with plastic glides to protect floor surfaces. All seams use reinforced nylon stitching set to 8mm pitch, with dual horizontal stitching channels on back cushions to deliver structured lumbar support. The leather finish resists liquid spills for quick, easy wiping, and the fabric achieves 50000 Martindale abrasion cycles, with 60% foam rebound, 480kg total static load capacity, and rated occupancy for 4 users. The frame supports users up to 1850mm tall. This sectional is ideally suited as primary seating for open-plan modern residential living rooms, fits seamlessly into luxury apartment interiors, and works for small office executive reception lounges. Recommended pairings include a 1200mm stone-top coffee table, complementary small side tables, and a 3000×4000mm low-pile area rug to define the seating zone. For procurement, note that each set ships in 2 cartons, with 1.8m³ packaging volume, 110kg packaged gross weight, and requires on-site assembly of 3 bolted base sections, with a 40 minute reference assembly time. Removable, replaceable cushion designs allow for long-term maintenance flexibility, making this piece a practical choice for both residential and light commercial reception use.
