Determining factors include your weight, height, and preferred sleeping position. General sleeping preferences may also play a role.
You should consider the following guidelines when choosing the right degree of firmness:
- The heavier you are, the firmer your mattress should be.
- Side sleepers and lighter-weight people often require softer mattresses than back and stomach sleepers.
- Conversely, back and stomach sleepers require firmer mattresses.
- All of that said, your physique and weight also play decisive roles.
Degree of firmness according to body weight
Bodyweight is a decisive factor in selecting the appropriate degree of firmness. However, since other factors such as height, sleeping position, and sleeping preferences are also decisive, everything must be considered on a case-by-case basis.

Degree of firmness according to sleeping position
Side sleepers: With side sleepers, only a few parts of the body touch the mattress. The entire body weight is condensed into these parts, putting an enormous amount of pressure on the mattress at these points. The side sleeper should choose a slightly softer mattress. This allows the hips and shoulders to sink in more deeply, keeping the spine in a healthy alignment.
Stomach and back-sleepers: Stomach and back sleepers can afford to choose a slightly firmer mattress. In both of these sleeping positions, the sleepers will need more support, especially in the lordosis area. This is necessary to prevent a hollow back.
Which degree of firmness do you choose for 2 people?
Couples should pay special attention to the degree of firmness before buying a mattress. This is simply because not every degree of firmness will be equally suitable for both partners.
One option would be to buy two mattresses that are the same height but have different degrees of firmness. In this way, each mattress will be adapted to each body type and will ensure that both partners can enjoy a restful sleep. One can easily buy a bed bridge to join the two mattresses together.
There are also mattresses that offer different degrees of firmness on different sides so that each half of the mattress can be individually adjusted. This is the ideal choice. In this way, it is possible for one person to lie on a softer side and one person to lie on a firmer side - all within one mattress.
The right degree of firmness for children
Firmness is also important to consider when you’re buying a mattress for your child. After all, your child should feel really comfortable on the mattress.
If the child's mattress is too firm or too soft, then there is a risk of spinal deformities developing, especially at an early age. Of course, this must be avoided.
Generally, a child’s mattress should be neither too firm nor too soft. Medium-firm mattresses tend to be a good bet.
Teenagers can already make use of adult mattresses and orient themselves according to more general firmness scales.
