1. In the production process of memory foam, there are several raw materials that must be made from American and Japanese companies in order to produce high-quality, good-feeling products.
2. The price of imported raw materials is high, and the minimum order quantity required is large. Generally, small factories can't afford it. It is often the case that substitute raw materials or super soft sponge formulas are used to impersonate memory sponges.

3. Density has a great influence on the performance of the memory foam, and it is directly proportional to the production cost of the product. The heavier the more expensive, the general performance is also good. As a memory foam used by the human body, in order to have sufficient supporting force, at least 80D or more. If If it reaches 120D, it can be regarded as the top slow rebound product.
4. The production process, product density, choice of auxiliary materials, etc., have also led to a wide gap in the quality of slow-rebound products from different manufacturers.
