Abstract: A method for improving blood circulation of seated or lying persons, wherein vibrations are released locally into the areas of the body of the seated or lying person, which are susceptable to blood stasis, by at least one vibration device (5) disposed beneath the sitting or lying surface with a predetermined or determinable frequency, characterized in that the vibrations are released by means of at least one vibration plate (6), which is movably guided in a direction transverse to the plane of the vibration plate (6) towards and away from the sitting or lying surface linearly and is operated with a frequency in the range of 5 to 30 Hz, so that the body is alternately raised and lowered from the sitting or lying surface, a brief pressure release occurring during the lowering movement so that a blood circulation can take place.
