Abstract: A support layer for a mattress and a corresponding manufacturing process are provided, comprising a first surface and a second surface, the second surface being disposed opposite the first surface. The first surface comprises a plurality of protrusions extending laterally to a length of the support layer, the protrusions defining a plurality of cavities extending laterally to the length of the support layer. The shape of the protrusions matches the shape of the cavities when the support layer is in a substantially planar state. The protrusions and cavities each have a base portion and a head portion, the head portion defining an undercut. Further, a mattress comprising at least one support layer is provided.

Abstract: A cushioning element (1) such as a mattress or a pillow for beds and the like, consisting of a support surface (2) having at least one primary hole (5) provided with at least two portions consecutive to each other in longitudinal section. The portions (5a, 5b) have different cross-section widths and are separated from each other by a transition region. The element (1) further has a base surface (3) opposite to said support surface (2), in which a secondary hole (7) is formed.
