The firmness of a mattress

What do you understand by the term ‘firmness’? Firmness is that quality that gives anything the ability to remain unchanged in the solid form. In terms of mattresses, firmness is the density of the foam of the mattress.

The density of the foam of the mattress:

The density of the foam of the mattress is the firmness of the memory foam mattress. The denser the foam is, the greater the density it has. The less-dense the foam is, the less firmness it has. 

Firmness scale: 

The firmness of a mattress has a scale starting from soft to firm. It can range from 0 to 10. 0 being soft and 10 being rock hard firm. Usually, it is preferred that a mattress should be at the level between 4 to 7, not too soft, not too hard, it should be medium.

Soft, medium and firm mattresses:

  • Soft mattress:  

A soft mattress is the one which has the firmness ranging between 3 to 5 on the firmness scale.

  • Medium mattress: 

A medium mattress is the one which has the firmness ranging between 6 to 7 on the firmness scale

  • Firm mattress:

A firm mattress is the one which has the firmness ranging between 7 to 9 on the firmness scale.

Sleep position determines the firmness of a bed: 

Back sleepers:

Back sleepers need a mattress that has body contouring and has the firmness between 4 to 7 on the firmness scale.

Side sleepers:

Side sleepers need a mattress that has firmness ranging between 3 to 6. They need a mattress to be more on the softer side rather than firm.

Stomach sleeper:

Stomach sleepers need a mattress that has the firmness ranging from 5 to 7. They need a mattress that is firmer than the back or the side sleepers. 

Female vs. Male mattress:

Females usually have a wider hip area and have more weight around the abdomen area than males. So, if a female sleeps on a soft mattress, their body will sink into it and give them back pain. That’s why males can have a bed that is on the softer side, but females cannot. 

Heavy people vs. lightweight people:

Heavy people need a mattress that is more on the firm side because their bulky body would sink into the bed if it’s too soft. This will lead to them having back problems. A lightweight person can choose a bed that is on the medium or softer side. 

How to choose the firmness of a mattress:

The firmness of a mattress depends on many things and factors such as:

  • Bodyweight of a person 
  • Sleeping positions 
  • Type of a mattress
