Tips on How to Choose the Right Mattress Firmness

The right level of firmness when choosing a mattress matters a lot. This is because it gives a huge impact on the level of comfort. However, since the firmness scale can be subjective on the sleeper's size, shape, and body weight, choosing the right mattress becomes quite tricky.

What is mattress firmness?

The firmness of the mattress is referred to as how comfortable a mattress can be. Is the mattress soft or firm? Does it give a good push back or it lets your body sink?

A mattress's firmness is described as soft, medium-firm, and firm. It is also scored from 1 to 10, where 1 is the softest and 10 is the firmest; the scoring is called as 'firmness scale'. To understand better, it is time to go over the differences.

  • Soft mattresses are often scored as 3 to 5/10. It is characterized by 'deep sinkage' and 'body contouring'. It gives you the feeling of 'in it' than 'on the top of it'.
  • Medium-firm mattresses are scored as 6 to 7/10. These mattresses have soft foams as the top layer and denser or sturdier foundations such as high-density poly foams or steel spring coils. Mattresses like this provide pressure relief and support. If you view the website, you'll find mattresses like these.
  • Firm mattresses are scored as 8 to 10/10. Mattresses with this level of firmness have little soft foams as the top layer and employ high-density polyfoam or spring coils as the foundation. Even though with firm construction, firm mattresses are known as highly supportive.

However, some manufacturers have a different breakdown of firmness levels. For instance, some great choices of mattresses are scored as 1-2 (very soft), 3-4 (soft), 5-6 (medium), 6-7 (medium-firm), 8 (firm), and 9-10 (very firm).

Then again, the firmness of the mattress is also subjective to the sleeper's weight and sleeping positions.


  • Individuals who weigh less than 130 pounds should consider using soft to medium-firm mattresses, which falls in between 3 and 6. This is because lighter sleepers do not tend to sink into the mattress, but mattresses with such firmness will provide better contouring and body support.
  • Individuals who weigh between 130 and 230 pounds should opt for medium to medium-firm mattresses, which fall in between 5 to 7 firmness levels. This gives enough cushioning and body support.
  • Individuals who weigh over 230 pounds should look for firmer mattresses, which range between 6 and 8. Heavier individuals tend to put more pressure on the mattress. Thus, choosing the wrong mattress firmness can make them sink exaggeratedly. If you think that these mattresses do not provide great cushioning and comfort, you got it wrong. There are firm mattresses are designed with a comfortable top layer but firm support, giving you similar comfortable experiences with individuals who use mattresses with different mattress firmness levels.


  • Side sleepers should opt for a soft to medium-firm mattress, which ranges between 3 and 7 firmness scale. These types of mattresses provide enough cushions on pressure points and proper body contouring, keeping your spinal alignment in position. At this source, you will find a lot of quality mattresses for side sleepers.
  • Back sleepers may opt for mattresses that provide support on the natural curve of the spine. These mattresses often have a soft to medium-firm scale, which is in between 4 and 7.
  • Stomach sleepers should avoid mattresses that make them sink because it can place the body in a 'U' shape, which is considered an unhealthy position. For this reason, it is recommended that stomach sleepers should opt for mattresses with good body support, which is a medium-scale (5 to 6).
