Abstract
A fiber cushion body, which is formed from cross-linked fiber material and which is resiliently deformable when load is applied along a main load direction, is treated using ultrasonic energy. A portion of the fiber cushion body is displaced, for example using a sonotrode, and ultrasonic vibrations are applied to the fiber cushion body to re-shape the fiber cushion body from a first shape to a second shape different from the first shape.
