How does granite’s density compare to other stones for outdoor sofa stability?

When selecting materials for outdoor furniture, stability is a critical factor, especially for sofas exposed to weather and frequent use. Granite stands out due to its exceptional density, which significantly contributes to the stability and durability of outdoor sofas.

Granite has an average density of 2.65 to 2.75 g/cm³, making it one of the heaviest natural stones used in outdoor furniture. This high density ensures that granite sofas remain firmly in place, even in windy conditions or on uneven surfaces. In comparison, lighter stones like limestone (2.3–2.7 g/cm³) or sandstone (2.2–2.8 g/cm³) may shift more easily, compromising stability over time.

Additionally, granite’s density enhances its resistance to wear and weathering. Unlike softer stones, granite is less prone to chipping or cracking, making it ideal for long-term outdoor use. Its weight also adds a sense of permanence and luxury to outdoor spaces.

For those prioritizing stability and longevity in outdoor furniture, granite’s density makes it a superior choice over lighter stones. Its natural strength ensures your outdoor sofa remains sturdy and stylish for years to come.
