If the bed is short, how about a stone mat?

As long as the firmness is enough, it is best to tie something on the contact surface to fix it. But from the perspective of feng shui, using stones to cushion the foot of the bed will affect the feng shui in the bedroom and even at home. In fact, as the saying goes, if you want good fortune, there are fewer things under the bed. Therefore, it is not recommended to use stones as mattresses.
