What are the differences in thermal conductivity between rattan and metal outdoor chairs?

When choosing outdoor furniture, thermal conductivity is an important factor to consider, especially in hot climates. Rattan and metal chairs are two popular options, but they behave very differently under the sun.

Rattan, a natural material, has low thermal conductivity, meaning it absorbs and retains less heat. This makes rattan chairs more comfortable to sit on during warm weather, as they stay cooler to the touch. In contrast, metal chairs, particularly those made of aluminum or steel, have high thermal conductivity. They quickly absorb heat from sunlight and can become uncomfortably hot, requiring cushions or shade for prolonged use.

Additionally, rattan's woven structure allows for better air circulation, further enhancing comfort. Metal, while durable, often lacks this breathability. However, metal chairs cool down faster once moved to shade, whereas rattan maintains a more stable temperature.

For those prioritizing comfort in sunny conditions, rattan is the better choice. If durability and quick cooling are more important, metal may be suitable, though with some trade-offs. Consider your climate and usage needs when deciding between these materials.
