The AIMENGSHI Black Tufted Upholstered 4-Seat Low-Profile Lounge Sofa, model SF-LP4T-BLK-01, features a sleek modern straight silhouette defined by a low, near-floor profile that anchors open, uncluttered layouts. Its backrest carries a precise grid-quilted tufted pattern secured by hidden plastic buttons, paired with seamlessly integrated curved padded armrests at both ends to create a soft, streamlined visual flow. The sofa has overall dimensions of 2460 x 1020 x 860 mm, with a 430 mm seat height, 630 mm armrest height from the floor, and 50 mm tall support feet, balancing relaxed proportions with clean, unobtrusive lines. Its structural core uses a kiln-dried solid hardwood and 18mm plywood frame with primary timber sections of 30 x 50 mm, held to a recommended 12% moisture content for long-term shape retention. The upholstery surface is 1.4mm thick corrected grain black leather, with stitched leather seams dividing the seating area into four individual 535 mm wide seat pads. Seat cushions use high-resilience polyurethane foam at 35 kg/m³ density with 60% rebound rate, wrapped in 20mm polyester batting, while back and arm padding uses 25 kg/m³ soft polyurethane foam with polyester fiber fill, with backrest cushions measuring 180 mm thick. Gloss black ABS plastic feet fitted with non-slip rubber pads complete the construction, and the leather upholstery offers 50000 Martindale cycles of abrasion resistance. Functionally, the sofa supports a 320 kg total static load, with an 110-degree reclined back angle tuned for relaxed lounge positioning. The full perimeter near-floor base eliminates wobble during regular use, while rubber foot pads prevent floor scuffing and unwanted sliding. The smooth leather surface allows simple wipe-clean maintenance with a damp cloth, and pre-styled throw pillows positioned against the armrests add supplementary lumbar support. Each cushion configuration includes four fixed divided seat cushions and two split back cushions, with 2140 mm of internal seating width and 710 mm of depth per seat cushion to accommodate four people comfortably. This sofa fits seamlessly as primary seating for open-plan modern residential living rooms, supports extended viewing sessions in home lounge or media rooms, delivers polished professional seating for modern office reception areas, aligns with minimalist aesthetics in open-plan loft apartments, and provides casual break seating adjacent to workspaces in residential open studies. For procurement, note that each unit ships in two cartons with a total packaged gross weight of 110 kg and 1.8 m³ packaging volume, requires 40 minutes of assembly per set, and carries an 85 kg net weight.
