Make sure that you always use a mattress cover between the mattress and the bed. Thus direct contact between the mattress and the bed is prevented, at the same time also preventing air humidity from gathering between the mattress and the bed. Using the mattress cover is a warranty condition.
Humidity is removed through airing and ventilation. During the night, humans produce half a liter to liter of sweat. The constituents of sweat (f.ex. salt, waste products, fat, toxins, dandruff and tallow) partially end up inside the mattress. If ventilation is too minimal, the gathered heat and dampness stay in the mattress. This leads to the development of mold spores.
The mattress is aired every time the linens are changed. This allows air to reach those parts of the mattress that are against the bed.
Air also reaches the bottom of the mattress
Dampness spots are formed under the mattress as a result of gathered heat and humidity if the mattress is aired too rarely or the mattress cover is not used or it is unusable. Airtight beds or bedrooms that are insufficient construction engineering-wise strongly increase the risk of forming dampness spots. Studies have shown that the forming of the spots is not caused by the materials used in the mattresses.
The mattress cover can be detached and washed in the washing machine in 60-degree water.
