The main materials of furniture are leather, solid wood, plate, cloth, marble, tempered glass and metal. In fact, the materials of furniture are not harmful to human body, but there are some chemical residues in the processing process, which are harmful to human body. Such as some inferior glue, paint, etc. When used in furniture production, it will leave harmful substances. If the products with quality assurance are strictly used, the harmful residue will be much less and the harm to human body will be lighter.

Solid wood should be regarded as the most natural and environmentally friendly material in furniture, and it has a long service life, so it is favored by consumers.

Therefore, we can't say which material is harmful to human body, only whether the products are strictly in accordance with production standards and use high-quality raw materials.
