What does mattress firmness mean?


In your search for the correct mattress, you are usually faced with the choice of mattress firmness. But what exactly does mattress firmness mean? When lying down, your spine should be aligned orthopedically correct. For this, it is important that the mattress is not too soft and not too hard. This is where the mattress firmness comes in and you must decide on what is suitable for your individual needs. If you choose the wrong degree of firmness it can lead to long-lasting damage to the spine, unnecessary tension and back discomfort.


If the mattress is too soft, it may give little support to the spine and the entire body will then sag. This then leads to constant back problems. In this case, a different mattress with a higher degree of firmness should be selected.


If the mattress is too hard, it may mean that your skin is being pressed too hard and not enough blood circulation is allowed to flow. This causes sleepy arms or legs. At night, your body must recover and regenerate, so it is very important to make sure your body has proper circulation. If you notice that your mattress is too hard you should look into sleeping on a softer mattress


Levels of Firmness

Different types of mattresses' firmness

  • Hardness 1:Mattresses with hardness H1 are very rare, as this degree of hardness is only suitable for adults up to 60 kg. These are usually custom-made.

  • Hardness 2:People weighing between 60 and 80 Kg should choose this degree of hardness.

  • Hardness 3:Mattresses with a hardness of H3 are most frequently bought. The upper limit of such a mattress is 110 Kg.

  • Hardness 4:A mattress with hardness H4 has an upper limit of 140 Kg and is described as very firm.

  • Hardness 5:The hardness degree H5 is one of the rarest degrees of hardness with the hardness H1. They are also usually made of special products for people weighing over 140 kg.

  • Depending on the mattress manufacturer, however, these details may vary. As there are no fixed rules on how to specify the degree of hardness, manufacturers are free to decide on these designations. Some manufacturers use, for example, designations such as "F1", "soft", "medium" etc.
