Abstract: The present invention refers to a cushioning member with an undulating conformation comprising a plurality of elastically deformable bands provided in a juxtaposed arrangement relative to each other according to a substantially longitudinal orientation, wherein each such band features a plurality of undulations which are inclined relative to a resting plane, and a plurality of joining strips are provided between at least two bands and arranged transversely relative to these bands. The cushioning member is produced as a single-piece molding, in which the bands are integral with the strips and are assigned a final and definitive shape thereof, as required for use to which the cushioning member is intended to be put.
