1. All more ventilation, there is no absolutely safe material, the key depends on how you reduce the concentration of harmful gases, even if the clothes, curtains, and plastic products we wear contain harmful ingredients such as formaldehyde....
The key is to see whether the materials used in the furniture meet the environmental protection standards. If it is reached, it is harmless, and you can't talk about plastic color change! Wood furniture is just as harmful if the exterior paint is not fully cured.
