Why is marble less common than granite for outdoor armchairs?

When selecting materials for outdoor armchairs, granite is often preferred over marble due to several practical reasons. Granite is significantly more durable and resistant to weathering, making it better suited for outdoor use. Its dense composition allows it to withstand rain, UV exposure, and temperature fluctuations without cracking or eroding easily.

Marble, while elegant, is softer and more porous, making it prone to staining, scratching, and damage from acidic substances like rain or spilled drinks. Over time, outdoor exposure can cause marble to lose its polished finish and develop a weathered appearance. Additionally, granite requires less maintenance and is more cost-effective for long-term outdoor furniture.

For these reasons, granite remains the top choice for outdoor armchairs, offering both beauty and resilience in harsh environments.
