Why does the bed in the lovers' hotel shake?

There are several possible reasons why the bed in the lovers' hotel will shake:

1. Vibration of the building itself, for example, in case of earthquake or slight deformation after the building is completed.

2. Acoustic design, such as springs, air cushions, sound insulation materials, etc. In the design of lovers' hotel, it is considered that the bed will produce reaction force when it vibrates, which will lead to the bed shaking.

3. The elasticity of the mattress. If the elasticity of the mattress is high, people will feel the jitter of the bed when lying on it, which is related to their own weight and body shape.

4. Vibration of other equipment in the room, such as air conditioner, air purifier, pendulum on the wall, etc.

5. People's psychological function, sometimes people will feel the bed shaking because of environmental changes or psychological hints, but in fact they are not really shaking when they sleep.

In a word, whether the bed in the couple hotel shakes or not is related to personal feelings and actual situation.
