One-third of life is spent in sleep, which measures whether a person's sleep is healthy, sufficient in time, good in quality and efficient. Sit still and relax; If you sleep continuously, you won't be disturbed. The depth of sleep applies to four signs of awakening fatigue: complete disappearance. The quality of sleep is closely related to consumers' choice of mattress permeability, decompression, support, compliance, bed surface tension, sleep temperature and sleep humidity. Because everyone's specific situation is different, such as height and weight, and personal habits and preferences, buyers should consider choosing an integrated mattress according to their own specific situation, local climate and personal income. The basic requirement of supine is to maintain the normal body curve of physiological lumbar lordosis and choose the best mattress function when lumbar scoliosis occurs. The function of mattress is to ensure that consumers get healthy and comfortable sleep. Two conditions for a good mattress: First, no matter what sleeping position, the spine can be kept straight, the pressure is balanced, and the human body can be fully relaxed. This requires a firm mattress. Hard mattress and soft mattress depend on the hardness of bushing spring. In addition to the necessary hardness, the spring should also play a supporting role and have good elasticity to combine rigidity with flexibility. Too hard or too soft, the rebound is not ideal. Lying on a mattress that is too hard is just the pressure of the head, back, hips and heels, and other parts of the body are not fully implemented. In fact, the spine is in a stiff and very tense aa state, which not only fails to achieve the best rest effect, but also does harm to the body by sleeping on such a mattress for a long time. The mattress is too soft, people lie down for a long time, pressing the internal organs, and the depressed spine bending state caused by a long time is unhealthy and uncomfortable. So use a mattress with moderate hardness. A good mattress not only makes people sleep comfortably, but also benefits their health. Under normal circumstances, long-term wrong sleeping posture, especially improper use of mattress spine, will cause displacement, thus stimulating the nerves inside the spine, and the nerve-controlled organs will gradually lose their normal functions. The mattress is too hard, which will not only oppress the nerves on the human back, but also affect the normal blood circulation for a long time, and also cause low back pain and sciatica. It causes oppression, promotes the blockage of human blood circulation, and causes the mattress to be too soft and uneven in weight to support left humpback and other sequelae. Therefore, a good mattress is the most urgent need for people to protect their spine. So, how can I buy a good mattress? Don't just look at the color or price when buying a mattress, choose a reputable brand, so as to ensure that the mattress itself has after-sales service among people with mattresses; In fact, the most important thing is quality. Ensure the quality and comfort of the mattress you bought.
