Abstract: An upholstered article is described, especially construed as a mattress 1.1, with a lower layer 2.1 and an upper layer 3.1 and intermediate elements 4.1, 4.2 arranged between the lower layer 2.1 and the upper layer 3, 3.1, wherein the intermediate elements 4.1, 4.2 each comprise a profile axis 6 extending transversely to the longitudinal direction of the upholstered article, wherein, in a cross section 7.1 perpendicular to the profile axis 6, a first intermediate element 4.1, 4.2 provides a first outer contour 8.1 along its periphery, and a second intermediate element 4.2 comprises the same outer contour along its periphery as the first intermediate element 4.1 or a second outer contour 9.1, wherein the first outer contour 8.1 comprises a first contour portion 10.1 with a nonlinear course facing towards the upper layer 3.1 or towards the lower layer 2.1 and wherein, in the first outer contour 8.1 and/or the second outer contour 9.1, at least one counter-contour region 11.

Abstract: The present invention provides a compressible electrode comprising a stably deformable polymer layer comprising a first outer surface, a second outer surface and at least one deformed portion formed as at least one indentation in the first outer surface and at least one corresponding protrusion in the second outer surface, and at least one non-deformed portion. The electrode further comprises at least one stretchable conductor layer arranged on or within the stably deformable polymer layer at the deformed portion and/or at the non-deformed portion. Further, the stably deformable polymer layer is stably deformed at the at least one deformed portion. The electrode further comprises an elastic material arranged on the first outer surface such that the elastic material fills the at least one indentation.
