When selecting foam cushions for your outdoor sofa, density plays a crucial role in balancing comfort and longevity. The ideal density for outdoor sofa foam cushions typically ranges between 1.8 to 2.5 pounds per cubic foot (PCF). This range ensures a firm yet comfortable seating experience while resisting sagging and wear from weather exposure.

Why Density Matters

Higher-density foam (2.0 PCF and above) offers better support and durability, making it ideal for frequent use. Lower-density foam (below 1.8 PCF) may feel softer initially but tends to flatten quickly under outdoor conditions. For humid or rainy climates, opt for high-resilience (HR) foam with a density of at least 2.0 PCF to prevent moisture retention and mold growth.

Additional Tips

- Pair foam with weather-resistant covers to extend cushion life.

- Consider polyester fiber wrap for added plushness without sacrificing durability.

- Avoid memory foam outdoors, as it absorbs moisture and loses shape.

By choosing the right foam density, your outdoor sofa cushions will stay comfortable and supportive for years, even in harsh weather.
