Abstract (en)
[origin: EP1557116A1] The mattress can be assembled of two layers of fleece material (1, 2) with cylindrical cavities (12, 22) shaped into the material by molding. A spring (5) is accommodated in every pair of cavities (12, 22) positioned opposite each other. The arrangement is covered with a layer of fleece on the top (31) and under the bottom (32). In a second version the springs (5) are accommodated in deeper single chambers which can be of different shapes as in other possible versions.
