How do thermal expansion differences affect joints in multi-material outdoor ottomans?

Thermal expansion differences in multi-material outdoor ottomans can significantly impact joint durability and structural integrity. When materials like metal, wood, or plastic are combined, each reacts differently to temperature fluctuations—expanding or contracting at varying rates. This mismatch stresses joints, leading to cracks, warping, or loosening over time.

To mitigate these effects, designers use flexible adhesives, expansion gaps, or weather-resistant fasteners. Choosing materials with similar thermal properties or incorporating buffers like rubber gaskets can also reduce stress. Proper maintenance, such as seasonal inspections and protective coatings, further extends the ottoman's lifespan. Understanding these dynamics ensures long-lasting, resilient outdoor furniture.
