A survey of soft and hard beds in a medical institution in the United States found that people who sleep in hard beds turn 70 to 80 times a night on average; While sleeping in a comfortable soft bed, the average number of turns dropped to less than 20 times, nearly three times the data difference. If the time difference between each turn is two minutes, it means that the hard bed with uncomfortable sleep is two hours less than the soft bed with comfortable sleep.
The hard bed is not soft enough to relax the muscles. Liu Shangli, a professor of orthopedics at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, told reporters that if muscles are not relaxed, our epithelial excitation system will not be quiet and it is easy to fall asleep. Sleeping on a hard bed is unscientific. Only sick people should sleep on hard beds, and healthy people should focus on comfort.

High-quality imported mattresses attach great importance to the combination of scientific research and practicality. Different fabric layers are necessary because different materials have different functions. The main function of natural latex is to resist bacteria and mites; Memory cotton can fit the human body better and disperse the vibration transmission caused by pressure and turnover; Gel adopts constant temperature gel memory sponge and particle gel technology, which comprehensively improves air permeability and heat dissipation constant temperature.
High-end imported brands usually use soft, skin-friendly and safe materials, such as natural cotton, wool, high-tech carbon fiber and Tencel, to enhance comfort. The edge of the mattress will also use high-density foam and breathable materials with good support, which not only ensures the durability of the mattress, but also ensures the breathability of the mattress.
