Now the latest green brown is also very common. It is recommended to buy green brown (also called 3E coconut dream, 3D green brown) instead of the traditional ordinary coconut tree. If glued, the formaldehyde content will be too high to meet the national formaldehyde content standard. Long-term use of mattresses with excessive formaldehyde will be harmful to your health.
How to distinguish? I'll teach you a simple identification method. The front and back of green brown are white, and the middle is brown. If the whole piece is brown without white, it is ordinary rubber coconut.
I have worked in a mattress factory for almost four years. This is a large manufacturer specializing in making mattresses (now it is estimated to be the largest manufacturer specializing in making mattresses in Shenzhen). I have seen hundreds of low-middle-grade and high-grade mattresses change from a steel wire to a mattress, and I know exactly what is added and what the structure is like. Even I know the purchase price of raw materials. Try not to listen to what the shopping guides say, because some shopping guides can't do anything for their work, even if they know that the products are not good enough, they won't tell the truth. The shopping guides are all trained by the company, memorized by looking for information on the internet, and then sold to customers in the form of endorsement fraud. The shopping guides in most specialty stores stay in the store every day, or attend those crazy sales training classes for days and nights. They have never been to the factory to see it with their own eyes, and they don't even know what the real structure of their mattresses is, so I believe half of the shopping guides talk too much. Ask me if you don't understand!
