Mattress Firmness: Which Level Is Best For Your Sleep?

Mattress firmness is a crucial and popular factor to consider when purchasing a new mattress. It refers to how hard or soft a mattress feels when you lie on it. 

Different people will have other preferences for their level of firmness. Choosing the right level of firmness can significantly impact your quality of sleep and overall comfort.

What Are The Levels Of Mattress Firmness? 

The level of firmness can be classified into soft, medium firm, firm to extra firm levels, each offering a unique feel and comfort. These levels range from soft to variation of the firm.  


Soft mattress level is a type of firmness that provides a plush and comfortable sleeping surface. It is generally considered the least firm option available. The soft level conforms closely to the body’s shape, distributing weight evenly to relieve pressure points, such as in memory foam mattresses.  

This is an excellent choice for people who prefer a cloud-like sleeping experience. They also are ideal for side sleepers, people with joint pain or arthritis, and those who want to sink into their mattresses for maximum comfort. Overall, soft-level cushions offer a relaxed and cozy sleeping experience.


Medium-firm mattresses offer a balance of firmness and support. They have a slightly softer top layer than firm cushions but still offer a significant level of support for the spine and joints. 

This mattress firmness is often preferred by people who sleep on their back or stomach, as it can help align the spine during sleep. Generally, a medium-firm mattress can offer a comfortable surface with the right support to help you sleep better.


A firm mattress is a great option for people who prefer a more structured sleeping surface. These cushions have a thick layer of supportive foam or coils in the base layer, which helps to keep the spine in alignment while sleeping. 

When selecting an ideal firmness level for a mattress, it’s essential to think about your own sleeping habits and preferences. This is because a cushion that suits you well can contribute to better, more refreshing sleep.

Extra firm

This firmness level is the firmest level available in the market. It provides maximum support and helps maintain proper spine alignment. Extra firm mattresses are recommended for those who have heavy weight or back pain issues. 

Extra firm mattresses usually have fewer cushioning layers, which makes them feel harder to the touch. These mattresses are made from high-density foam or supportive coils, which prevent you from sinking into the mattress, especially heavy people. 

However, this firm mattress may not be comfortable for everyone, and it’s recommended to test them before purchasing.

How Does Mattress Firmness Affect Sleep Quality? 

The firmness level you choose can support your sleep deeply. They can help with your body alignment, reduce pressure, create comfort, and fit with your sleep position. 

Support and alignment

A mattress that is too firm can cause pressure points, leading to discomfort and poor circulation. Meanwhile, a cushion that is too soft can result in improper spinal alignment, causing back pain and muscle tension. 

So, choosing the right level of firmness provides proper support to the body’s natural curves, allowing spine alignment. This reduces the risk of developing pain and stiffness and maintains better sleep quality.

Pressure relief

The firmness level affects pressure relief, which can either help or hinder your sleep quality. A softer mattress might create pressure points that cause discomfort, while a too-firm one can lead to stiffness and pain. 

The optimal level of firmness for pressure relief also depends on your body type and sleeping position. But in general, medium-firm mattresses tend to provide the best pressure relief for most people. 


The firmness can greatly affect your level of comfort while sleeping. Side sleepers may experience discomfort due to pressure points caused by a mattress that is excessively firm. Besides, a too-soft cushion can lack support and cause spinal misalignment. 

As a result, the right firmness level offers a balance of support and comfort, which can help prevent aches and pains.

Motion transfer

The firmness level can also affect motion transfer, or how much movement is felt by a sleeping partner. A firmer mattress tends to have motion isolation better, as it doesn’t allow as much sinking or contouring. This can be ideal for couples who don’t want to be disturbed by each other’s movements during the night. 

What Are The Factors To Consider When Choosing Mattress Firmness? 

Now that you know how important the firmness level is, it’s time to learn how to pick the right one for you. 

Sleeping position

A firmer mattress is ideal for back sleepers as it offers a supportive surface that keeps the spine aligned. Next, a soft bed is better suited for a side sleeper as it conforms to the body’s curves and relieves pressure on the hips and shoulders. 

Stomach sleepers should opt for a medium-firm cushion to prevent their spine from being curved or hunched. If you pick the wrong firmness level, it can lead to discomfort, pain, and bad-quality sleep.  

Body weight

Your body weight is an important factor to consider when choosing the right firm mattress. If you are a heavier sleeper, you will require a firmer cushion to provide adequate support and prevent sagging over time.

Health conditions

Your health condition is an important consideration when choosing a mattress. For example, if you suffer from chronic back pain, a firm feel could help relieve discomfort and improve sleep quality. 

But if you experience pressure points or soreness due to a health condition, a medium-firm mattress may be a better option. Taking into account your specific health conditions can help choose a suit mattress firm that will promote your overall health.

Personal preferences

Everyone has their unique sleeping habits and comfort levels, and it’s essential to choose a mattress that suits your specific preferences. So, if you like a firmer cushion for more support or a softer cushion for extra relaxation, try different levels of firmness before making a decision.


The firmness of your mattress plays an important role in your daily sleep. It’s vital to find a balance between different factors and choose the best mattress that meets your needs. Well-chosen mattress firmness can provide the necessary support for well sleep quality.
