The best choice of mattress should start with the function of the mattress. The function of the mattress is to ensure that the consumer gets a healthy and comfortable sleep. There are two criteria for a good mattress: one is that the person can stay straight stretched regardless of the sleeping position; the other is equal pressure, people lying The whole body can be fully relaxed. This involves the softness of the mattress. The softness and hardness of the mattress depend on the softness and hardness of the inner liner Spring. In addition to the necessary hardness to support the spring, the spring should also have a good resilience, that is, the so-called rigid and soft.
Too hard or too soft, rebound is not ideal. The mattress that is too hard is lying on the top, only the four points of the head, back, buttocks and heels are under pressure. The other parts of the body are not completely dead. The spine is actually in a tight and tense state, which not only does not reach the best rest. The effect, and sleeping on such a mattress for a long time will also be detrimental to health. A mattress that is too soft, the person sinks down when the body is lying down. The spine is bent for a long time, causing pressure on the internal organs. It takes a long time, which is also unhealthy and uncomfortable. Therefore, a soft and moderate mattress should be used.
How to measure the hardness of the mattress? How to call it soft and moderate? The simplest measurement method is: lie flat, stretch the hand to the neck, waist and hip to the thigh. There is no gap; turn it to one side, use the same method to try to see if there is any gap between the concave part of the body curve and the mattress. If not, it proves that the mattress and the person are sleeping, neck, back, waist, The natural curves of the hips and legs fit together, and such a mattress can be said to be moderately soft and hard. Everyone has different soft and hard preferences for mattresses. Some people like to sleep on hard beds. Some people prefer to sleep on soft beds. What kind of mattress is a good mattress? 30 years ago, Germany once sparked a discussion about whether it was a hard mattress or a soft mattress. The discussion led to the participation of the German ergonomics and led to the study of human sleep posture.
The result of the study is that both a hard mattress and a soft mattress are not good for healthy sleep, and the correct mattress should be a high-elastic mattress. That is to say, when the force applied to the mattress is large, the mattress should drop much and generate more support for the human body, and vice versa. This is because the human body is a curve. Only on a high-elastic mattress can the body and the back be supported, especially the waist should have strong support, so that the human body can relax and fully rest. Since the human spine is shallow S-shaped, it is necessary to have a support of appropriate hardness when lying down, so the elastic mattress is essential for the comfort of the human body and the quality of sleep. The choice of mattress can not rely solely on self-feeling, too soft or too hard to be appropriate, but based on the difference between height and weight. A lighter bed with a lighter weight makes the shoulders and hips slightly plunged into the mattress and the waist is fully supported. The weight-sinker is suitable for sleeping on a hard mattress. The strength of the spring can give each part of the body a proper fit, especially if the neck and waist are well supported. You can refer to the height, weight and soft and hard table of the mattress, which will be more scientific.
