Degree of hardness
Our Recommendation for Mattress Firmness:
- Firmness Level 2 = medium firm up to approx. 80 kg body weight
- Firmness Level 3 = firm approx. 81–110 kg body weight
- Firmness Level 4 = very firm approx. 111–130 kg body weight
The compression hardness determines the firmness level of a mattress:
The compression hardness indicates how much pressure (kilopascals) is needed to compress a mattress from its original state by 40 percent. The higher the compression hardness of a mattress, the firmer is its core and the faster it returns to its original shape when the pressure is released. With a low compression hardness, the core is softer and more susceptible to high loads, which can lead to the formation of indentations. Based on the compression hardness, the respective firmness level of the mattress is determined, which should serve as guidance for the consumer.
