Product Description

The DIPU Three-Seat Upholstered Leather Sofa, model LTHR-SOFA-3S-2800, is a purpose-built residential seating solution defined by clean modern lines and a streamlined low-profile silhouette. Its overall dimensions measure 2800 x 980 x 850 mm, with a 160 mm leg height that creates a sleek, grounded block base aesthetic. Wide, integrated padded armrests trimmed with vertical metal accent strips frame three individual fixed seat and back cushion sections, finished with precision stitched seams for a tailored, refined look. Two coordinating decorative throw pillows—one with a houndstooth woven cover and one with a matching leather-textile printed cover—add subtle visual depth, and can be repositioned or removed as desired. Built for consistent long-term use, the sofa features a kiln-dried solid pine and engineered wood inner frame with primary sections sized to 30 × 50 mm and a recommended moisture content of 12%. Seat cushions use 45 kg/m³ high-density polyurethane foam with an 180 mm thickness, while back cushions use 35 kg/m³ medium-density polyurethane foam split into dedicated lower lumbar and upper back support zones, paired with a sinuous steel spring seat base for even weight distribution. Upholstered in top-grain corrected leather tested to 50000 abrasion cycles, with a 60% foam rebound rate and 8 stitches per 30 mm seam pitch, the sofa sits on hard black non-marking plastic glides and supports a total static load of 450 kg at 115 kg net weight. Designed for three adults, the fixed configuration has no recline mechanism, and cushions support removable, replaceable service for extended usability. It is ideally suited as primary seating for open-plan or dedicated residential living rooms, aligning with contemporary, light luxury, and mid-century modern decor schemes, and durable enough for 6 hours of daily family use. It also fits small office reception areas and executive lounge waiting zones. For optimal layout, pair it with a 1200x700mm coffee table positioned 400mm from the front seat edge. For procurement, note the product ships as one set across two cartons with a total packaged volume of 1.8 m³ and packaged gross weight of 110 kg per item, requiring 40 minutes of assembly per unit. Select configurations that match planned interior palettes to leverage its versatile design across eligible space types.
