In the field of wood furniture, both solid wood and artificial boards have the performance of moisture absorption and expansion according to the physical characteristics, so that the wood furniture is unstable and specific in warping, stretching, deformation, bulging, cracking and the like, and the service life of the product is influenced.

Because the fiber of the wood contains certain moisture, and the wood can change according to the change of the humidity and the temperature in the air in the environment, the wood absorbs the moisture in the environment with high humidity, thereby causing the expansion; moisture is released in a dry environment, causing shrinkage, during which warping and deformation may occur.

The phenomenon that the dimension of the wet material is reduced due to drying is called dry shrinkage; the phenomenon of the dry material increasing its size and volume by absorbing water is called wet swelling. The phenomena of dry shrinkage and wet expansion mainly occur under the condition that the moisture content of the wood is less than the fiber saturation point, and when the moisture content of the wood is above the fiber saturation point, the size and the volume of the wood cannot be changed.

The wood of the manufactured furniture is subjected to drying and shrinking treatment, so that the moisture content of the solid wood can be continuously changed and adjusted according to the change of the humidity and the temperature in the later use environment until the solid wood is adapted to the environment, but the deformation is caused by wet expansion, which is the reason why the solid wood furniture is difficult to avoid expansion and deformation.
