Hello. I need help from you guys. I'm in a battle with the neighbors who are living above me. They stomp on my thin ceiling. After a few months I caught them waiting until I go to sleep and bothering me by shaking my unit somehow. I retaliated by nudging, not hitting, the ceiling. It seemed to work. So I thought........ They have now caused a problem I can't begin to solve. Here goes.......I have a metal frame recliner and a sofa. So now whenever I sit in either, I get sensation of the cushion slowly expanding and contracting under my ass and back. They are able to do this over and over again silently. I lay down on carpet and could feel slight tremble. Its a slow and steady inflate and deflate. And when its near full expansion they are able to shake me in my chair a little. Please help.
