Temperature sensing characteristics: refers to the induction of human body temperature, gradually becoming soft, while absorbing human pressure to adjust the body to the most comfortable posture. For the part below which does not touch the human temperature, it still maintains sufficient support force; the simplest way to identify temperature products is to put them in the refrigerator cabinet, take them out after a few minutes, and find that the product will harden; or take the product coat away, put the hands on it, without giving pressure, you can also feel the hand sinking, that is, temperature. Induction.

Viscoelastic properties: refers to the product under pressure and subsidence, but will not show strong resilience (such as clay subsidence under pressure); when the pressure is removed, the product will gradually return to its original shape (such as spring recovery); in business, "slow rebound" will also be called "zero pressure sponge", meaning that when lying on it, it feels like floating on the water or on the surface. In fact, the slow resilient material can adjust the irregular shape of the compression to the most balanced state, that is, it can slowly deform to adapt to the compression object, but also provide the most uniform support. The blood circulation pressure of human skin is 36 mmHg. When the pressure of memory cotton is evenly distributed at each point, it can generally reduce the pressure to less than 36 mmHg. It makes people feel the blood is smooth, as if there is no place to oppress, not that there is no pressure on memory cotton.
