Solid wood furniture
 
It is mainly made of red sandalwood, Huanghua pear, ivory wood, oak and teak. Mahogany furniture is the most typical hardwood furniture.
Although glue (containing formaldehyde), wood paint and other chemical fillers are inevitably used in the production process, the whole production process is environmentally friendly and strict, and the formaldehyde content is not higher than 1.5 mg / 100 g.
The surface decoration materials are made of high-quality special hardwood paint, and the contents of benzene and toluene are strictly controlled in the national compulsory standards. The main pollution index of furniture is formaldehyde, benzene and toluene, but the content is very small. When buying this kind of furniture, you don't have to worry about its environmental protection.
The real hardwood furniture products have no flavor, let alone pine flavor.
The production cycle of precious hardwood furniture is very long. Generally, the production cycle is 50, 60 years, and some even 100 years. Most of them are primitive forests; Generally speaking, most of the valuable hardwood comes from the tropical rain forest area of Southeast Asia, and part of it comes from the cold temperate zone. Once it is cut down for hundreds of years, it can not be repaired, so the price of hardwood furniture is expensive.
Due to the rise of mahogany furniture in Ming and Qing Dynasties, the precious hardwood used for mahogany furniture was almost cut down in China. Due to the long growth period, the diameter of the existing trees in China is too small to be used as furniture materials
Due to the influence of temperature difference and humidity, the mahogany furniture replaced by hardwood is easy to cause quality problems such as wood cracking, tenon loosening and paint falling off in the process of transportation and use.
