What are the differences between composite and granite outdoor chairs in thermal mass?

When selecting outdoor furniture, understanding thermal mass—the ability of a material to absorb and retain heat—is crucial for comfort. Composite and granite chairs differ significantly in this aspect. Granite, a natural stone, has high thermal mass, absorbing heat during the day and releasing it slowly, making it warm to sit on in cooler evenings but uncomfortably hot in direct sunlight. Composite materials, often made from wood fibers and plastics, have lower thermal mass, staying cooler in the sun but lacking granite's heat-retaining properties. Granite's density gives it superior heat retention, while composites offer more temperature stability. Your choice depends on climate and usage—granite suits cooler regions, while composites are better for hot, sunny areas. Both materials have durability benefits, but thermal performance varies, impacting comfort year-round.
