The term compression hardness refers to the force that must be expended to compress foam 40 percent of its normal height.
It is expressed in kilopascals (kPa). The methods for determining the compression hardness are determined. The compressive strength is significantly influenced by the structure of the molecular structure of the foam.
It is largely responsible for the degree of hardness of a foam mattress. For high-quality lying comfort in mattresses, for example, cold foam with a foam compression hardness of 50, that is converted at 5 kPa is used.
The mattress size plays no role in the compression hardness; a mattress 140 × 200 has the same compression hardness in the same production in 90 × 200 sizes. In addition to the compressive strength, there is the indentation hardness or compressive resistance in physics, which is measured in Newton (N). To determine the compressive strength, the specimen is compressed by two larger plates or a special tester. For determining the indentation hardness, however, plates smaller than the object to be tested are used.
Room weight and storm hardness:
Volume weight and compressive strength are contrary to many assumptions, not one and the same. The density of the volume describes the density, the amount of material used for mattresses, the compressive strength of mattresses, the force used to compress them. Both components characterize the mattress hardness of foam mattresses. The lower the compression hardness, the softer the foam. Therefore, the compression hardness affects the feeling of lying. However, a foam mattress with high compression is not the same weight and a soft not necessarily easy. The density of a mattress, however, should fit somewhat to the compression value.

Baby mattress compression size
Baby mattresses are specially adapted to the ergonomic and health requirements for baby and toddler. The compression hardness is not yet a strong criterion for the mattress purchase, because the baby has a low body weight and therefore exerts only minor pressure on the mattress. With a baby mattress, therefore, a lower compressive strength and a lower volume weight are already sufficient to ensure the necessary strength and a comfortable feeling of lying at the same time.
