The hardness of the mattress depends on the hardness of the internal spring. In addition to supporting hardness, the spring must have good resilience, which is the so-called rigid-flexible combination. Too hard or too soft, the rebound is not ideal. People who lie on a mattress that is too hard are only under pressure at four points: head, back, hip and heel, and other parts of the body are not fully implemented. In fact, the spine is in a stiff and tense state, which not only fails to achieve the best rest effect, but also harms health if you sleep on such a mattress for a long time.

A mattress that is too soft will droop as soon as people lie down, and the spine will bend for a long time, which will cause oppression to the internal organs. After a long time, it will be unhealthy and uncomfortable. Therefore, you should choose a mattress with moderate hardness.

A good mattress can not only make people have a comfortable sleep, but also be good for their health. Generally speaking, long-term wrong sleeping posture, especially improper use of mattress, will cause the displacement of vertebral segments, which will stimulate the nerves inside the spine and lead to the gradual loss of normal function of nerve-controlled organs. Too hard mattress will not only oppress the nerves in the back of human body, but also affect the normal circulation of blood. After a long time, it will also cause backache and sciatic nerve pain.

Due to oppression, blood circulation is blocked, which will promote human aging, while the mattress is too soft, which will make the weight of the human body get unbalanced support, leaving behind sequelae such as hunchback. Therefore, a good mattress is the most urgent need for people to protect their spine. So, how can I buy a good mattress?

When buying a mattress, don't just look at the color or price, choose a reputable brand, so as to ensure after-sales service; In fact, the most important thing is the quality of the mattress itself and the people who use it. Only in this way can you ensure the quality and comfort of the mattress you choose.

From the point of view of protecting the spine, it is suggested to consider the spine-protecting mattress, also known as the head-up mattress, whose head is inclined and can be used to correct the spine. It also comes with a custom-made pillow, which can be used as an ordinary mattress.
