How does wood expansion and contraction affect the stability of furniture over time?

Wood expansion and contraction can affect the stability of furniture over time by causing warping, cracking, or loosening of joints. As wood absorbs or releases moisture from the environment, it swells or shrinks, leading to changes in the shape and structure of the furniture. This can result in misalignment of parts, weakening of connections, and overall reduced stability of the piece. Proper construction techniques and materials can help mitigate these effects and prolong the lifespan of the furniture.
