<p>Mattress forming a surface (L) to lie on across its length and width has many adjoining core parts lying in the direction of the mattress's length which can be removed and which extend across the whole width. They are all enclosed by a shell body. A high variability of the course of the firmness throughout the lying surface is achieved, in that the core parts have at least two opposite-facing laying surfaces of different firmnesses (I,II,III, Iv) from which the surface on which to lie down on can be composed by turning selected core parts.</p> |
