Mattress theory evaluates whether a mattress is good or bad

In the 1980s, a new theory-the mat theory was created and developed. According to the cushion theory, the following factors are used to evaluate the quality of a mattress.

　　 Functional mattresses should provide a suitable micro-environment for people's sleep, so that both the mind and body can be fully rested, thereby eliminating fatigue and gathering energy. The mattress factory should have good stability, good fixability, suitable size, weight and thickness, good friction characteristics between the cushion and cushion cover, beautiful appearance, reasonable price, durable and easy to clean.

　　The main structure of a comfortable mattress must conform to the principles of human mechanics. The hardness of the mattress is very important. A very hard mattress will only make people's head, shoulders, hips, hips, ankles and other parts contact the bed, while other parts of the body are not fully settled. It causes the weight of the body to compress the local blood vessels, making the blood unable to flow smoothly. A mattress that is too soft can provide the maximum support surface for the body, and can reduce the local pressure of the compressed tissue layer, so as not to hinder blood circulation. However, it cannot provide adequate support and can cause improper back bending and cause body aches. If a person often turns over during a night’s sleep, a mattress that lacks support will consume too much energy and feel tired when getting up in the morning.

　　 Generally speaking, a comfortable mattress should provide good support for the human body during sleep. No matter what sleeping position a person sleeps in, his spine curvature is basically in line with the normal physiological curve. Therefore, a comfortable mattress must have a certain degree of elasticity and hardness. In addition, comfort also includes good thermal conductivity, breathable and moisture-proof.

　　Safety The safety of mattresses has many indicators, such as the mattress material should have good flame retardancy; people lying on the bed for a long time will not harm the soft tissues; the chemical composition of the mattress material should not affect people’s health Wait.
