在我看来，这类产品是很普及的产品，只是他们是否愿意把好的材料用在产品上

In my opinion, this type of product is a very popular product, but whether they are willing to use good materials in the product, I do not feel the high calculation difficulty, so we signed a contract with a large factory and clearly stated the requirements. What material, how much material is used, how much weight, and the data are all controlled. The product that comes out is what we want. If we don’t know anything, the product factory that comes out can cut corners, because we don’t know the specific situation, such as memory foam. You know, but what is the density of the sponge and what is its resilience. Usually, products with a higher density will rebound better. I have used some memory foam pillows and they will not rebound after a period of time.

在我看来，这类产品是很普及的产品，只是他们是否愿意把好的材料用在产品上，我感觉不到很高的计算难度，所以我们和大工厂签合同，把要求写清楚，什么材料，用料多少，重量多少，把数据都控制起来，出来的产品就是我们想要的，如果我们什么都不知道，出来的产品工厂可以偷工减料，因为我们不知道具体的情况，例如记忆海绵你是知道的，但海绵是什么密度，回弹力是多少，通常密度比较大的产品回弹才会好，我用过一些记忆海绵的枕头，一段时间以后就不回弹了<br>
