SPRING MATTRESS'S HARDNESS TESTING-SYNWIN

  What is the softness and hardness? The easiest way to measure is: Lie on your back, stretch your hands to the neck, waist and hips to the thighs and stretch them inwards to see if there is any space; then turn over to one side and use the same Try to see if there is a gap between the sunken part of the body curve and the mattress. If not, it proves that the mattress fits the natural curves of the neck, back, waist, hips and legs of a person during sleep. Such a mattress It can be said to be soft and hard. Everyone has different preferences for the hardness of mattresses. Some people like to sleep on hard beds, while others like to sleep on soft beds. What kind of mattress is a good mattress? Thirty years ago, there was a debate in Germany about whether a firm mattress is better or a softer mattress. That discussion attracted the participation of the German ergonomics bachelor community and led to the study of human sleep posture. The result of the study is that no matter whether the mattress is too hard or too soft, it is not good for human healthy sleep, and the correct mattress should be a high elastic mattress. That is to say, when the force exerted on the mattress is large, the mattress should drop much and produce more support for the human body, and vice versa. This is because the human body is a curve, and only on a high elastic mattress can the human body and the back be supported, especially the waist should have strong support, so that all parts of the human body can relax and get full rest. Since the human spine is in a shallow S shape, a support with appropriate hardness is required when lying down, so an elastic mattress is very important to the comfort of the human body and the quality of sleep. The choice of mattress should not rely solely on self-feeling, too soft or too firm is not suitable, but according to the difference in height and weight. Lighter people sleep on softer beds, so that the shoulders and hips sink slightly into the mattress and the waist is fully supported. Heavy people are suitable for sleeping on a firmer mattress. The strength of the spring can give every part of the body a proper fit, especially whether the neck and waist are well supported. You can refer to the height, weight and mattress firmness comparison table, it will be more scientific.
