Is the hollowing out of box spring beds normal?

The hollowing out of a box spring bed is a sign of quality. Here we explain how it happens.

Hollowing with natural products

MATRI beds have a very high level of construction including the underbed, box spring mattress and comfort topper. They are made from carefully selected and certified European raw materials. For the most part, these are soft natural products such as wool, latex and jute. All soft materials absorb the pressure when lying down and give way. Depending on the product, the so-called recovery property varies, i.e. the tendency of the material to return to its original state. Cold foam, for example, returns to its original shape immediately after standing up. The rather fluid-soft latex, on the other hand, returns to its original shape more slowly, while wool and jute sometimes do not return at all. Such materials only return to their original state when they are consciously stretched, rolled or stretched. This is why natural products often develop hollows after a few days: Hollows form at pressure points. This shows that the material adapts individually to the body weight, physiognomy and lying position. This is the desired goal, comparable to a pair of high-quality leather shoes that you first have to break in for some time. The effect of the hollow formation occurs – quite individually for each user – after a certain period of use, i.e. the material adjusts strongly at the beginning of use and only slightly afterwards. How the small hollows form on a box spring bed also depends on personal handling, care and sleeping habits. A restful sleep, for example, favours depressions, while the effect of depression formation does not occur, is weaker or delayed in a more mobile sleep. If the comfort pad or mattress is always loaded in the same place, it adapts to the body much more quickly. Such points can be recognised, among other things, by pressure marks of the slat base on the underside of the material. The process of hollowing out in the box spring bed is also influenced by the heat and moisture that each person individually gives off to their bed during sleep. Regularly turning and moving the mattress or shaking the comfort overlay counteracts the formation of cavities. In this way, the material unfolds and sets itself up again.

Hollows are a natural reaction

Soft materials should and must adapt to the body weight and stature. Their supportive and relieving capacity – and thus the individual sleeping comfort in the box spring bed – is in no way impeded by the formation of hollows. A defect, however, would be material damage. This would be the case if, for example, the wooden bed frame were to break or a steel spring were to burst. FENNOBED offers a 10-year guarantee against such fractures in the frame and springs.

Sleeping comfort develops with

Since sleeping habits can change over the course of a lifetime, it can of course become desirable to replace individual elements of the box spring bed, such as the underbed, the mattress or the comfort pad. Thanks to the construction of our box spring beds according to the special MATRI modular principle, you can adapt the individual bed elements to your evolving comfort needs even years after purchase. We thus offer under-beds and mattresses in different degrees of hardness. And our comfort overlays have different material cores with which the surface comfort can be fine-tuned.
