How does prolonged exposure to moisture weaken natural rattan outdoor loungers?

Prolonged exposure to moisture significantly weakens natural rattan outdoor loungers due to the material's organic composition. Rattan, derived from tropical palm stems, absorbs water when left damp for extended periods. This absorption causes the fibers to swell and soften, leading to structural instability. Over time, repeated wetting and drying cycles degrade the rattan's natural resins, making it brittle and prone to cracking. Mold and mildew growth further accelerate deterioration, compromising both aesthetics and strength. To preserve rattan loungers, store them in dry conditions or use protective covers during rainy seasons. Regular cleaning and applying sealants can also help minimize moisture damage.
