When investing in premium outdoor furniture from Hongyi Outdoor Furniture Factory, understanding cushion thickness becomes crucial for both comfort and durability. Our sofas feature precisely engineered cushions ranging from 4 to 6 inches in thickness, specifically designed to withstand outdoor conditions while providing exceptional seating comfort. Each cushion incorporates high-density foam cores measuring 30-35kg/m³ in density, ensuring optimal support without compromising softness. The thickness specification varies across collections: our premium lounge series utilizes 6-inch thick cushions with triple-layer construction, while standard seating options maintain 4-inch thickness with reinforced edges. This careful thickness calculation prevents premature sagging and maintains shape integrity through seasonal changes. Beyond mere measurements, our cushion thickness works harmoniously with advanced drainage systems and quick-dry foam technology, creating the perfect balance between luxurious comfort and practical outdoor performance. The strategic thickness also complements our powder-coated aluminum frames, resulting in furniture that remains visually appealing and functionally superior for years of outdoor enjoyment.
