Together with slatted frames are mattresses the main responsible for a healthy and restful sleep! For a long time, the so-called spring mattresses have proven themselves. These mattresses have an interior made of individual, movable steel springs, which provide for a certain stability. However, it comes with spring mattresses to a flat yielding. The comfortable further development is the pocket spring mattress. In this mattress, each spring is sewn into a fabric bag, whereby the adjacent springs no longer resonate under load. Latex mattresses made of synthetic or natural latex also provide comfort. Latex mattresses have different hard zones, allowing them to adapt perfectly to human anatomy. The same dimensional stability and elasticity as latex mattresses offer foam mattresses. For the foam mattress, the quality is determined by the volumetric weight. Extremely comfortable are foam mattresses with a density of 45 to 55kg per cubic meter. However, particularly adaptable are water mattresses, which are adjusted solely by the change in the amount of filling in the degree of hardness. Although the comfort of lying at the beginning gets used to, but they provide a high pressure relief and are ideal for back problems.
