The Youwei model LSEC-DB-3400 is a modern dark brown L-shaped leather sectional sofa with a fixed right-side chaise, designed with clean, minimalist lines defined by wide block armrests, a low-profile raised base, and neatly tailored loose seat and back cushions. Its corner configuration creates a structured, space-defining layout that anchors seating areas without visual clutter, with a deep chaise lounge section extending from the main seating unit to support relaxed, laid-back postures. Built for long-term regular use, the sofa features an internal frame of solid kiln-dried hardwood reinforced with 12mm plywood, with primary frame sections sized for structural stability and timber dried to a recommended 12% moisture content to prevent warping. The seat support system uses elastic rubber webbing suspension, paired with solid black-stained hardwood block feet fitted with pre-installed felt pads to protect floor surfaces. Upholstered in 1.2mm thick dark brown smooth faux leather match with a 50000 Martindale abrasion resistance rating, the sofa uses high-tenacity polyester bonded thread with consistent 8 stitches per 30mm seam pitch for durable, neat finishing. Seat cushions feature a high-density 45kg/m³ polyurethane foam core wrapped in polyester fibre with a 60% rebound rate, topped with 250mm thick cushioning, while back cushions use a soft blend of polyurethane foam and loose polyfibre fill. Padded armrests wrapped in matching upholstery sit 200mm above the 450mm high seat surface, with 550mm tall back cushions for steady upper body support. Locking metal brackets connect modular sections securely, and the low base leaves sufficient floor clearance for easy routine cleaning. All seat and back cushions are removable to simplify upkeep, with replacement compatible with standard removable cushion servicing methods. Each seat supports a 150kg weight capacity, with total seating for 4 people. This sectional is well suited as the primary lounge seating for residential living rooms in family homes or apartments, and works effectively to zone open-plan lounge areas while offering generous casual seating capacity. Its deep chaise design delivers extended comfort for home media room use during long viewing sessions, while its neutral, streamlined aesthetic fits modern furniture showroom displays and casual visitor seating in small contemporary office reception areas. For procurement, note the unit ships in 3 cartons with a 175kg gross shipping weight, requires 60 minutes of on-site assembly, and fits 18 sets per 40ft HQ container. Coordinate delivery access to accommodate the largest 2200 x 1050 x 650mm shipping carton, and confirm on-site handling capacity to safely maneuver the 156kg assembled unit to its intended placement location.
