<p>This document presents a bed arrangement where a swinging back-and-forth motion is directed to a person lying on the bed. This is achieved by disposing magnetic pairs inside a mattress and generating a variable magnetic field between the magnetic pairs. The variable magnetic field causes the motion of the magnetic pairs, thereby moving a support structure of the mattress. This motion causes the motion of a top side of the mattress where the person lies, thereby directing the motion to the person.</p> |
