Science has proved that soft mattresses will reduce the support to the spine, and hard mattresses are not comfortable enough, so mattresses that are too hard and soft are not conducive to healthy sleep. The most basic requirement of a healthy mattress is that it can meet the normal state of the human spine, rather than being flat as seen by the naked eye. When lying on your back, the mattress can keep the lumbar lordosis and the body curve is normal; Lie on your side to avoid bending the lumbar spine. Compared with many mattresses in China, the American lace mattress divides the human body into three areas, emphasizes the hardness of the middle area of the mattress, and adopts the international patent-the median back protection line to support the spine. When the head and legs are soft, the shoulders and hips will sink properly, and the back will rise, so that the body support is evenly and reasonably distributed, which can not only play a full supporting role, but also ensure the reasonable physiological curvature of the spine; Make sleep more stable, improve the overall sleep efficiency, improve the physical comfort and mental state after waking up, and get a higher quality sleep than using wooden boards, brown or ordinary sponge mattresses. You like the difference between soft and hard, you must try it. I bought a brown pad online before, which is very hard and not very good brown, and it also cost a lot of money. Personally, I suggest buying some softer mattresses. As long as the mattress has good support, it is very good for the body, can support the spine, help improve the quality of sleep, and can adjust its state well. Like Europe, people sleep in soft beds from childhood to adulthood. Because as long as the mattress has good support, you will not be tired and sleep comfortably. Mattresses that can often be seen on the market now include springs, latex, high-elastic cotton and quasi-foam cotton. There are also many kinds of springs, mainly distributed pocket springs and independent springs, and one is all-steel spring. Latex cushions are imported mattresses. There are also many kinds of imported mattresses, if the mattress surface is made of cooling materials or plants. This kind is generally mouth-based, and the price is relatively high. Moreover, if you choose a bed, you don't have to pay attention to the mattress, but mainly look at the skeleton of the bed, which has a great relationship with the effect and service life of the mattress. Generally, ribs have no toughness, so their support is not good. Therefore, red beech is generally chosen as the main skeleton, which has very good toughness and resilience. Don't neglect the stability of the bed. If the stability is not good, the bed will rattle and move, which will affect the quality of sleep and life. China people's sleep habits are hard, which is also the reason why China people are prone to lumbar disc herniation at the age of 50-60. Nowadays, many mattresses are humanized and designed in different regions, and the load-bearing capacity of mattresses can be designed according to the weight of different parts of the body. Friends say that mattresses and beds are quite comfortable.
