How to measure the hardness of a mattress

How to make a custom-made mattress called moderate hardness? The simplest measurement method is: lie on your back, stretch your hands toward the neck, waist and hips to the three obvious bends between the thighs, and see if there is There is no gap; turn over to one side and try the same method to see if there is a gap between the concave part of the body curve and the mattress. If there is no gap, it proves that the mattress is related to the neck, back, waist, and hips of the person during sleep. It fits closely with the natural curve of the legs, so the mattress can be said to be moderately soft and hard. Everyone has different preferences for the softness and hardness of the mattress. Some people like to sleep on a hard bed, while others like to sleep on a soft bed. What hardness mattress is a good mattress? Thirty years ago, Germany once triggered a discussion about whether a hard mattress is better or a soft mattress. That discussion aroused the participation of the German ergonomics bachelor's circle and led to the study of human sleep posture. The result of the study is that whether a mattress is too hard or too soft is not good for healthy sleep, 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 a lot 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 both the human body and the back be supported, especially the waist must have strong support, so that all parts of the human body can be relaxed and fully rested. Custom-made mattresses Because the human spine is shallow S-shaped, a support with appropriate hardness is required when lying down, so a flexible mattress is very important to the comfort of the human body and the quality of sleep. The choice of a mattress cannot be based solely on self-feeling. It is not appropriate to choose a mattress that is too soft or too hard, but based on the difference in height and weight. Lightweight people sleep on a softer bed, so that the shoulders and hips sink slightly into the mattress, and the waist is fully supported. The heavy weight is suitable for sleeping on a harder mattress. The strength of the spring can give proper support to every part of the body, especially whether the neck and waist are well supported. You can refer to the comparison table of height, weight and mattress softness, it will be more scientific.
