Little bit of context
I've always lived in a house. The same goes for my girlfriend. Now we moved together, but we are living in an apartment. We are not used to some of the noises/closeness that people living in that kind of buildings face.
The "problem" is that sometimes during sex, the bed moves a lot. We live in a 7th floor, and while we found hot that the bed moves, we are worried that noises caused by the bed being dragged during the act could bother people living in the 6th floor, specially those whose apartment is exactly below ours. We are not used to living in an apartment so we are not sure about this.
The bed's type is sommier, and has 5 legs (I believe that's the correct term), one in each corner and one in the center
What can I add/use to prevent movement, or better, if there's any movement, to prevent noises/vibration caused by dragging?
I am not completely sure if this is the right place to ask. Thanks
