What are the differences between indoor and outdoor foam densities used in landscape sofa cushions?
When selecting foam for landscape sofa cushions, understanding the differences between indoor and outdoor foam densities is crucial for durability and comfort. Outdoor foam densities are typically higher, ranging from 1.8 to 2.5 pounds per cubic foot (PCF), to withstand weather elements like rain, UV rays, and temperature fluctuations. These foams are often treated with additives for mold and mildew resistance.
Indoor foam densities, on the other hand, usually range from 1.5 to 1.8 PCF, prioritizing comfort over resilience. They lack weather-resistant properties but offer superior softness and flexibility. For landscape furniture, opting for high-density outdoor foam ensures longevity, while indoor foams are better suited for protected environments. Always consider usage and climate when choosing the right foam density for your cushions.
