Why are the contraction joints of mahogany furniture different?

The size of the contraction joint varies for various reasons:

There are problems in the treatment of wood drying by manufacturers, which leads to unstable shrinkage of furniture at home;

There is also the local climate, and the dryness and humidity in the air have a great influence on the shrinkage of mahogany.

Then there is air conditioning, and water contact with wood will affect the shrinkage of mahogany. .

Expansion joints are specially reserved to adapt to different environments, and their width is generally within 0.3-0.5 cm. The purpose of leaving expansion joints is not to crack the frame or tenon of furniture. Spring and winter, the air is dry. When making furniture with artificially dried wood, expansion joints are generally needed, otherwise the big edges will be damaged after the arrival of wet summer.
