When measuring people’s dimensions, I noticed a high deviation in the distance between the middle of the neck and the tailbone. Consequently, the contact point at the buttocks had to have a larger shape. After an experiment with a subwoofer that proved to be too fragile, a vibrator motor attached to a circular plate turned out to be an appropriate solution to cover a larger surface.
