Slatted base for furniture on which to lie

In known slatted bases, the upper slats are assigned lower slats which prevent the mattress from sagging. In this case, the upper slat deflects in a first bending region on its own and in a second bending region together with the lower slat. By means of the slatted base according to the invention, a high degree of lying comfort is achieved at reduced production cost. For this purpose, the upper slats (1) consist of profiled bars which are open at the bottom, are U shaped, are curved upwards and are made of fibre-reinforced plastic. The lower supporting slats (4), which consist of straight profiled bars with approximately rectangular cross-section, are arranged therebelow, plunging from below into the upper slats (1). As a result of this configuration of slats and supporting slats, a very high degree of adaptation during deflection is achieved, without complicated, laterally tiltable slat holders being necessary.
