The memory foam material can change the softness and hardness according to the temperature. It will slowly become softer as the temperature rises. When the human body comes into contact with the memory foam, the memory foam will sense the human body temperature, become soft and evenly absorb the human body pressure. , so mattresses and pillows made of memory foam have a higher degree of fit with the human body.
