I wonder if having springs in the bed legs would help to damp vibrations. Or.. something like that

I remember a Youtube video about a story of a skyscrapper that added something to damp vibrations so that it would be more comfortable due to high winds or something like that. If it's feasible to damp vibrations on a whole building, you can do it on a smaller scale as well
