About 35% of a person’s life is spent in bed. With people’s living standards improve, more and more people are paying attention to mattress comfort. Studies have shown that the pressure distribution between the mattress and the human body affects people’s sleep quality, and the pressure distribution is one of the main indicators to measure the comfort of the mattress. In this paper, the comfort of mattresses with different hardness is studied. The pressure distribution and the subjective comfort score are analyzed with the trend of the mattress hardness. The recommended values of the mattress hardness and the pressure are obtained. The research results can provide basis and reference for the design of the mattress.
