Description

The invention relates to a mattress with a core cushion covered by a top cushion.

Such an embodiment can be found in the German utility model 297 20 057.7. The mattress disclosed here, consisting of foam and/or latex, is made of three layers, where the upper and lower cushions are identical and zones extending over the full width of the mattress have different degrees of hardness, while the core cushion has a uniform degree of hardness over the length of the mattress.

The invention is based on the task of developing a mattress that ensures even more precise body support.

This object is achieved according to the invention in that the upper cushion is firmly connected to the core cushion, has design features for surface ventilation and consists of a slow-20 recovery foam that has a high density, becomes softer under the influence of temperature without losing its elastic recovery forces and regains its original hardness when it returns to the starting temperature, and in that the core cushion

has zones of different hardness that extend across the full width of the mattress.

Such a slow recovery foam is currently being offered by a Scandinavian company in particular. The properties of this foam are used according to the invention to further refine the body support provided by the zones of different hardness provided in the core cushion, which is already tailored to the body contour or body weight. Under the influence of the body pressure exerted by the body lying on the mattress, the slow recovery foam becomes warmer and therefore softer in the pressure areas, so that the corresponding body part can sink deeper into this area. The body support is provided by the interaction of the body contour and body weight, whereby a highly precise adjustment is achieved. Since the slow recovery foam has a high density and therefore poor air passage, design features for surface ventilation are provided in the upper cushion according to the invention.

For example, a total of five or seven different hardness zones can be provided in the core cushion; the length and the respective supporting force of each hardness zone can correspond to the examples in the utility model specification cited at the beginning.

The top cushion can be glued to the core cushion made of foam and/or latex. In order to ensure air exchange between the core cushion and the top cushion, it is advisable to provide partial gluing between these mattress parts, i.e. to avoid continuous surface gluing. The partial adhesive application can be carried out, for example, by spraying a grid of glue.

According to the invention, a three-layered mattress can be provided, with the upper and lower cushions being identical. The identical structure of the upper and lower cushions means that the mattress can be turned over.

To be able to use the foot part of the mattress as a head part and vice versa, it is useful if the different
Hardness zones are arranged in a mirror image to the center of the mattress. 5

In the embodiment according to Figure 1, the top cushion 2 has a ribbed profile 4 running across the full width of the mattress to achieve surface ventilation. In the embodiment according to Figure 2, the ribbed profile 4 of Figure 1 is replaced by a knobbed profile 5. In the embodiment according to Figure 3, a hole structure 6 running perpendicular to the lying surface is also provided to achieve sufficient surface ventilation instead of the surface profiles shown in Figures 1 and 2.
