Mattress hardness and marking. How to choose the most suitable one?
When choosing a mattress, one of the most important criteria is its firmness. This determines whether your body will be properly supported during sleep, how you will feel in the morning, and whether your sleep will be of high quality.
Manufacturers often denote mattress firmness with the letter H (from the German word Härtegrad – degree of hardness), followed by a number, e.g., H2, H3, H4.
What does the H mattress rating mean?
- H1 – very soft mattress, suitable for relatively light individuals.
- H2 – soft / medium-soft, recommended for up to ~70-80 kg.
- H3 – medium-firm, suitable for most people, for weights from ~70 to 100 kg.
- H4 – firm, intended for heavier individuals or those who prefer a solid base.
-
H5 – very firm, typically used in rehabilitation or for people weighing over 120 kg.
Numbers may vary slightly between manufacturers, so it is always worth checking the specific description.
How to choose the right mattress firmness?
Based on body weight:
- Lighter individuals (up to 70 kg) often feel more comfortable on softer (H2) mattresses.
- Medium-weight (70–100 kg) people are best suited for H3 – medium-firm mattresses.
- Heavier than 100 kg should choose firmer options, e.g., H4 or even H5 mattresses, so that the body receives sufficient support.
Based on sleep position:
- For side sleepers – softer mattresses (H2 or H3) are more comfortable, as they allow the hips and shoulders to "sink" into the mattress.
- For back sleepers – medium-firm (H3) mattresses are recommended.
- For stomach sleepers – firmer mattresses (H4) are best to prevent the back from arching.
Based on personal comfort
Some people enjoy the feeling of "sinking" into a mattress – in that case, H2 is suitable. For others, a solid base is the most important, so they will choose H4.
Summary
Proper mattress firmness is one of the most important factors for a good night's sleep. Consider your weight, sleep position, and personal comfort preferences. H2, H3, or H4 – there is no "best" one, only the one most suitable for you.
