What are the differences in thermal expansion between canvas and polyester loungers?

When choosing outdoor furniture, understanding the thermal expansion properties of materials like canvas and polyester is crucial for durability and comfort. Canvas loungers, made from natural fibers, tend to expand and contract more significantly with temperature changes. This can lead to loosening or tightening of the fabric over time, affecting the lounger's shape and comfort. Polyester, a synthetic material, has lower thermal expansion, making it more stable in varying temperatures. This stability ensures the lounger maintains its form and comfort longer. Additionally, polyester is more resistant to moisture and UV rays, further enhancing its longevity compared to canvas. For those in climates with extreme temperature fluctuations, polyester loungers may be the better choice due to their minimal thermal expansion and superior durability.
