How does the density of marble compare to other stones for bench stability?

When selecting materials for outdoor benches, stability and durability are key factors. Marble, known for its elegance, also boasts a high density—typically ranging from 2.5 to 2.7 g/cm³. This density makes it heavier and more stable than many other stones, such as limestone (2.3–2.7 g/cm³) or sandstone (2.2–2.8 g/cm³), though slightly less dense than granite (2.6–2.8 g/cm³).

The higher density of marble contributes to its resistance to shifting or tipping, especially in high-traffic areas or windy environments. However, its porosity can make it susceptible to weathering over time compared to denser stones like granite. For long-term bench stability, marble offers a balance of aesthetic appeal and functional weight, though granite may provide superior durability in harsh conditions.

Ultimately, the choice depends on the desired balance between beauty, weight, and environmental resilience.
