Remember the key point: "Menglily does not make latex mattresses"
Secondly, Menglily mainly makes non-temperature-sensing memory foam mattresses, which is their patent. What they currently buy are "zero-pressure mattresses". Of course, the raw material is still "memory foam", but they have added many functions to the original basis, such as cooling gel.
Next, if you want to compare latex and memory foam, you can search the Internet for information on latex materials. I will tell you if it is too terrible. Basically, today's mattresses are made of synthetic latex. Latex cannot be solidified in the first place. Some chemical materials must be added to make a mattress. Those who say natural latex mattresses are nonsense. Just go to the Internet and find out. Therefore, you can tell which one is strong and which one is weak.
Memory foam material has been used in various aspects abroad for a long time, such as mattresses, pillows and so on. At present, I am personally more optimistic about memory foam.
