• According to “Effect of Humanized Design of Mattresses on Sleep Health”, people need proper support from mattresses to maintain the natural curvature of the spine when they are in a lying position. Long-term use of a mattress that is too soft or too hard will directly affect the health of the spine. and back muscle strain. When the mattress is too hard: the pressure in the supine sleeping position is concentrated on the buttocks and back, and the waist lacks effective support, which is not conducive to muscle relaxation and maintaining the natural state of the spine; the pressure in the side sleeping position is concentrated on the shoulders and buttocks, the lumbar spine is laterally lying, and the pressure on the intervertebral disc increases . When the mattress is soft: due to the increased contact area between the person and the bed, the rolling friction required for turning over and adjusting the posture increases, the energy consumption of the human body is large, and the posture adjustment is difficult, which is not conducive to blood circulation, nerve conduction and muscle relaxation. At the same time, when the mattress is soft, the buttocks can easily sink deep into the mattress, which is not conducive to maintaining the natural posture of the spine.
