Are mattresses as firm as possible?

A mattress that is too hard will oppress the body. Many people believe that sleeping on a "hard bed" is better for the spine, but in fact, a mattress that is too hard is not good. When the surface of the body comes into contact with the harder bed board, the more prominent parts of the body will bear all the pressure of the body like a "bracket". Over time, it will cause pain and affect blood circulation, resulting in frequent turning over during sleep, and the quality of sleep is greatly reduced. Medical pressure ulcers are caused by similar reasons.

A mattress that is too soft will cause back pain. A mattress that is too soft will lead to inappropriate sleeping positions. The waist, where the center of gravity of the body is located, falls excessively with gravity, causing excessive kyphosis of the spine, especially the lumbar spine, which is exactly the opposite of the natural physiological curve of the human body. In order to keep the spine normal, the small muscle groups around the spine will coordinately contract to maintain stability. Over time, the small muscle groups will fatigue, resulting in symptoms of stiffness and soreness, so back pain occurs. Therefore, a mattress that is too soft or too hard will not work.

A "good mattress" is one that is neither soft nor hard, and has enough support.
