What are the differences in thermal conductivity between granite and concrete outdoor chairs?

When choosing outdoor chairs, understanding the thermal conductivity of materials like granite and concrete is crucial for comfort and durability. Granite, a natural stone, has higher thermal conductivity than concrete, meaning it absorbs and transfers heat more efficiently. This makes granite chairs feel hotter in direct sunlight but cooler in shade. Concrete, with lower thermal conductivity, retains heat longer but warms up more slowly. Both materials are durable, but granite's heat sensitivity may require cushions for comfort, while concrete offers a more moderate temperature. Consider climate and usage when selecting between these two robust options for outdoor seating.
