<p>A composite bed inlay is solving the technical problem of how to give a user the possibility of choosing a bed inlay of suitable hardness through a modular access. The essence of the invention is in composing a combined bed inlay with the combination of horizontal layers, where each of them may have various characteristics. Each horizontal layer can be made of a different material and also carried out according to a different concept. So there can be, for example, a spring mattress as the top layer, followed by a latex layer, then a layer made of foam and at the bottom, a layer made of latex.
