Density: One of the most important quality features

      Comments Off on Density: One of the most important quality features

When mattress comparison you should pay special attention to the density of the mattress, as this miter on the longevity and thus on the quality of the mattress. This applies in particular to cold fluff and latex mattresses. The volume weight given in kg / m³ indicates how much material was used in the production of the core per volume. The higher the density, the higher the quality of the mattress, but the higher is its weight. However, a mattress with a high density is also characterized by a long service life and is associated with a low risk.

In addition to the density, the compressive strength is also important. The compressive strength indicates how much pressure must be exerted on the mattress before it is compressed to a certain height. The higher the compressive strength, the stronger the foam and the faster the mattress returns to its original shape.

Hardness: The interaction of volume weight and compression hardness

In order to be able to find the perfect mattress for a restful sleep in the test, you should pay particular attention to the degree of hardness of the mattress. The degree of hardness is composed of the density and the compressive strength and is divided into different levels.

Caution: There is no standard regarding the classification of the degrees of hardness. For example, one manufacturer can offer a mattress with hardness H1, which is suitable for persons up to 50 kilograms, while another manufacturer offers his mattress in hardness H1 for persons up to 60 kilograms. In addition, the size of the person determines which degree of hardness is the right one: With a size of 1.85 m and a weight of 90 kilograms, one sleeps differently on an H3 mattress than with a size of 1.60 m and a weight of 90 kilograms. Nevertheless, one can go out in the search for the appropriate degree of hardness of the following rules of thumb:

Hardness selection:

  • H1 for people up to 60 kilograms
  • H2 for people up to 80 kilograms
  • H3 for people over 80 kilograms
  • H4 for people over 100 kilograms
  • H5 for persons over 120 kilograms
