<p>The present invention relates to an assembly, comprising an element defining a lying or support surface, such as a foam layer forming a core of a mattress, and a device associated with the element for adapting the form of the lying or support surface in waves, wherein the device comprises at least one selectively expandable and/or compressible body. The body is further embedded in or arranged under a part of the element which is lower-lying during use and has above it at least a greater part of the thickness of the element. The body acts on a wave part of the element so as to selectively bring about waves in the lying or support surface, which wave part is connected via a hinged configuration to other parts of the element.</p> |
