What are the differences in thermal mass between stone and concrete outdoor chairs?

When choosing outdoor furniture, thermal mass is an important factor to consider, especially for chairs made of stone or concrete. Stone chairs, such as those made from granite or marble, have a higher thermal mass compared to concrete chairs. This means they absorb and retain heat more effectively, staying warm longer in cool weather but also becoming very hot in direct sunlight. Concrete chairs, while still having significant thermal mass, tend to heat up and cool down more quickly than stone. This makes them slightly more adaptable to changing temperatures but less effective at retaining warmth. Both materials are durable and stylish, but your choice may depend on your climate and how you plan to use the chairs. For hot climates, stone chairs might become uncomfortably warm, whereas concrete could be a better option. In cooler areas, stone's heat retention can provide added comfort. Understanding these differences helps in selecting the best outdoor seating for your needs.
