Bed height

Too high or too low will only cause inconvenience to the bed. If it is too high, it will cause inconvenience. If it is too short, it will be easily damp. It is easy to inhale dust on the ground during sleep and increase the working pressure of the lungs.
The healthy height of the bed can also be measured by the height of the face from the ground. The standard is 46~50 cm. This is because the seat has a healthy height of 40 cm. When sitting on a bed, the height of the 46 cm bed is about 40 cm after being pressed.
