Why choosing mattress firmness is essential

The firmness of a mattress directly influences the quality of sleep, back support, and the feeling of comfort throughout the night. A mattress that is too soft can cause the pelvis to sag, while a mattress that is too firm can create pressure points on the shoulders and hips.

Contrary to popular belief, there is no single ideal firmness for everyone. The right choice always depends on your body type, your sleeping position, and your personal preferences.

How to tell if your mattress is too soft

A mattress that is too soft can lead to:

• visible sagging in the middle

• a feeling of rolling toward the center

• lower back pain upon waking

• a lack of support when you change positions

When support is insufficient, the spine is no longer properly aligned, which can cause muscle tension.

How to tell if your mattress is too firm

An excessively firm mattress can cause:

• shoulder pain

• tension in the hips

• a sensation of compression

• frequent nighttime awakenings

A mattress that is too hard prevents certain parts of the body from sinking in naturally, which disrupts blood circulation and muscle relaxation.

Which firmness to choose based on your weight

Weight is one of the most important criteria for determining the appropriate firmness.

• under 70 kg: balanced or medium comfort recommended

• 70 to 100 kg: firm support recommended

• over 100 kg: firm or high-density mattress preferred

A mattress suited to your weight ensures lasting support and limits premature wear.

Which firmness to choose based on your sleeping position

Sleeping on your side

A slightly soft to balanced comfort is recommended to allow the shoulders and hips to sink in slightly.

Sleeping on your back

A balanced to firm support is advised to maintain the natural alignment of the spine.

Sleeping on your stomach

A relatively firm mattress is preferable to prevent the pelvis from sinking in excessively.

The role of mattress type in the feeling of firmness

The perceived firmness also depends on the mattress technology.

Pocket spring mattresses generally offer more dynamic and stable support.
Memory foam mattresses offer a more enveloping feel while maintaining progressive support.
Technical foams and latex often offer a good compromise between elasticity and stability.

It is therefore important to evaluate the actual firmness based on the complete structure of the mattress and not just its label.

Why testing a mattress remains the best solution

Even with all the recommendations available, the feeling remains personal. Two people with the same weight may prefer different levels of comfort.

Testing a mattress allows you to verify:

• back support

• the sensation of the top comfort layer

• shoulder comfort

• overall stability

Conclusion: finding the ideal firmness

The best mattress is neither the firmest nor the softest, but the one that ensures natural body alignment while remaining comfortable.

Taking the time to try out several levels of firmness and benefiting from professional advice helps to lastingly improve your sleep quality.
