Wood has the characteristics of shrinkage and swelling. Even if wood is made into furniture, it will still be affected by the environment and humidity, and will expand and shrink with changes in relative temperature and humidity. When the air is extremely dry, furniture can lose moisture and shrink, and in severe cases, cracks can occur on the surface of the furniture. Conversely, when humidity increases, furniture absorbs moisture and expands slightly.

Therefore, when it is wet in rainy days, the furniture should be placed away from the window to prevent the furniture from being damp and mildewed. If the living environment is too humid or dry, the legs and feet of the furniture in contact with the ground can also be wrapped with protective pads to prevent moisture or cracking.

Likewise, when the weather is hot and dry, furniture should be placed out of direct sunlight. Or use translucent window screens to reduce direct sunlight, which neither affects lighting nor damages furniture.
