The so-called bentwood is not a kind of natural wood, but the wood is formed through post-processing. Bentwood furniture is made by using the elastic principle of the external nature of wood. After steam treatment, it can be easily bent into a certain shape, which replaces the traditional mortise manufacturing process of furniture. It can be said to be one-piece molding. It’s just that the manufacture of bentwood furniture has higher requirements for wood and technical equipment. The raw materials usually used to manufacture bentwood furniture are selected ash, elm, oak or birch.
