The AIMENGSHI White Modular Three-Seater Upholstered Sofa, model M3S-WHT-SQB-001, features a clean, modern low-profile silhouette with a segmented linear form suited to a range of interior aesthetics. Its overall dimensions measure 2600 x 1060 x 930 mm, with a seat height of 430 mm, 750 mm wide individual seat cushions, 710 mm deep seating surfaces, 410 mm thick seat cushions, 300 mm thick back cushions, 180 mm tall armrests measured from the seat, and 200 mm wide armrests. The frame is constructed from kiln-dried solid hardwood with reinforced corner blocks, paired with a seat support system of 70 mm wide elastic webbing over a sinuous spring base. It rests on black matte engineered wood block legs fitted with non-slip, scratch-resistant TPE rubber pads. External upholstery is matte white polyester fabric rated for 30000 Martindale cycles of abrasion resistance, with a 3 mm per stitch seam pitch. Seat cushion cores use 28D high-density polyurethane foam with an integrated pocket spring layer for 60% rebound rate, back cushions are filled with a blend of 25D polyurethane foam and polyester fiber wrap, and armrest top toss cushions use polyester fiber fill with matching white fabric covers. All cushions are secured to the base with hidden hook-and-loop strips. The three base modules join via all-metal clip connectors for rigid alignment, and sections can be rearranged into alternate linear layouts with compatible additional modules. Back and arm cushions adjust to multiple reclined angles via a non-slip base, hidden zippers on all cushion covers allow removal for dry cleaning, and non-marking foot pads protect hardwood, tile, and low-pile carpeted surfaces. The pocket spring core resists permanent cushion indentation under regular use, and cushions are designed for easy removal and replacement. The sofa supports 360 kg total static weight, with a 120 kg per-seat static load capacity, and has a net weight of 95 kg. It is suited for main living room seating in apartments and family homes, informal meeting and break areas in home or small office settings, short-term rental and home staging properties, and low-traffic office reception and waiting lounges. It pairs seamlessly with matching ottomans and side tables for coordinated lounge sets. For procurement, note that each unit ships in 2 cartons with a packaged gross weight of 110 kg, requires 40 minutes of assembly per set, and has a packaging volume of 1.8 m³.
