Is The Mattress Really As Soft As Possible?

From the above, it can be concluded that there are two main criteria when selecting mattresses.
The first thing is to keep the spine straight and stretched, so that regardless of the sleeping position, it can give people a good sleep state. Secondly, the pressure should be equal. As long as a person can fully relax while lying in bed, it is enough. Then, appropriate mattresses should be selected based on height, weight, sleeping posture, etc. Most people who weigh over 80KG should choose some harder mattresses. A hard mattress can affect blood circulation, while a soft mattress can cause back pain and back pain upon awakening, and it can also easily lead to hunchback. The normal physiological structure of the human spine appears as an S-shaped curve from the side. If you sleep on a hard bed, it cannot match the normal curve of the human spine, and the waist cannot be supported. Over time, it can also cause strain and worsen symptoms such as low back pain.
