Modern Bed types include double beds, single beds, sofa beds, rollaway beds, children's beds and more. People's sleep is mainly to restore physical strength and energy, therefore, the choice of bed can not be taken lightly. There are many shapes and materials for the bed, but it is necessary to pay attention to the choice according to their own needs. For the elderly, children should not use iron beds with enamel and horns.

In general, we must first consider the impact of the softness and hardness of the bed on the body. The human spine is made up of a section of vertebrae that can be bent or stretched. If the bed is too soft and the body sinks so badly, it will inevitably lead to excessive bending of the spine, causing the waist muscles to stretch and appear uneven, and there will be a feeling of incompetence after getting up, and even feel low back pain. For adolescents who are in the stage of growth and development, children will affect the normal development of bones and are extremely detrimental to physical development. On the other hand, if the mattress is very hard, it will inevitably feel panic, and the musculoskeletal will be uncomfortable, which is also unfavorable for relieving fatigue and restoring physical strength.

Secondly, pay attention to the insulation, heat dissipation and moisture absorption of the bed. Generally speaking, people's body temperature is usually around 36.5 degrees, and the temperature on the surface of the body is slightly lower, about 32 degrees to 33 degrees, and when lying down, it is about one degree lower than when standing. When choosing a bed, you should consider keeping your body around body temperature when you sleep, and temperature balance is good for sleep. In addition, we must also consider the changing factors of the four seasons in spring, summer, autumn and winter. The moisture absorption and moisture permeability of the bed are mainly related to the material, thickness and size of the mattress.
