According to Feng Shui, in a bedroom the energy has to flow naturally above and below you. At this point we focus especially on the area below (since above, energy does not usually find problems when it comes to flowing), where energy will find an obstacle when it comes to flowing, in a bed that has a sofa or a closed work structure. Therefore, beds with legs are the ideal choice in this philosophy.
If we have a low ceiling, the essential thing is to paint it white to modify the optics and thus allow the energy to flow properly.
