Rain and high humidity can affect wooden furniture in ways you may not notice at first. Prolonged humidity can cause wood to absorb moisture, leading to sticking drawers, swollen edges, bubbling veneers and musty odors. Wooden furniture manufacturer know that this type of damage rarely happens overnight. Instead, it develops gradually as the furniture is repeatedly exposed to humid conditions, eventually causing warping, swelling or weakened joints. The good news is that many of these problems can be prevented with regular care and a few simple precautions throughout the season.
