Have you ever wondered whether you should be sleeping on a soft, medium or firm mattress? With so many options available, choosing the right mattress firmness can feel overwhelming. What feels comfortable to one person may feel completely different to another.
Your sleeping position is a useful starting point, but it is not the only factor to consider. Your body weight, personal comfort preferences and the way a mattress is constructed all influence how it feels when you lie down.
Understanding these differences can help you make a more informed decision and find a mattress that suits your individual needs.
At Driftaway Beds & Pillows, we believe that better sleep starts with understanding what works for you. Let's explore mattress firmness, how it relates to your sleeping position and what to consider before choosing your next mattress.
What Does Mattress Firmness Actually Mean?
Mattress firmness describes how soft or firm a mattress feels when you lie on it. It is one of the first things people notice when trying a new mattress, but it is important to understand that firmness and support are not the same thing.
A soft mattress generally allows you to sink further into the sleeping surface, creating a more cushioned feel.
A medium mattress aims to balance cushioning with a more balanced, less yielding surface feel.
A firm mattress generally feels more resistant to compression, allowing less initial sinking into the sleeping surface.
These descriptions are useful starting points, but there is no universal firmness scale used consistently by every mattress manufacturer. A medium mattress from one brand may feel different from a medium mattress from another.
Your body weight and the mattress construction also affect how firm a mattress feels to you. For this reason, it is worth considering more than the firmness label alone.
Mattress Firmness vs Mattress Support: What's the Difference?
Firmness and support are often used interchangeably, but they describe two different aspects of a mattress.
Firmness is about how the mattress feels. It describes the sensation you experience when you lie down, from a soft, cushioned surface to a firmer, more resistant one.
Support is about how the mattress accommodates your body. A supportive mattress should allow your body to rest comfortably without excessive sinking or an uneven sleeping position.
A mattress can feel soft while still providing suitable support, just as a firm mattress may not necessarily be the right choice for every sleeper.
The goal is not simply to choose the firmest mattress available. It is to find a mattress that provides an appropriate balance of comfort and support for your body and preferred sleeping position.
How Does Your Sleeping Position Affect Mattress Firmness?
Your sleeping position can influence how much cushioning you prefer and where you need your mattress to accommodate your body.
While individual preferences vary, the following guidelines can help you narrow down your options.
1. Side Sleepers
Side sleepers place much of their body weight around the shoulders and hips. A mattress that feels excessively firm may not provide the surface cushioning they prefer in these areas.
A soft to medium-feeling mattress may therefore appeal to side sleepers who enjoy a more cushioned surface.
However, the ideal firmness also depends on body weight and the mattress construction. A lighter sleeper may experience a mattress differently from a heavier sleeper, even when both choose the same firmness rating.
What to consider: Look for a mattress that provides comfortable cushioning around your shoulders and hips while allowing the rest of your body to rest in a comfortable, supported position.
2. Back Sleepers
Back sleepers often look for a balance between cushioning and support. A mattress that feels too soft may allow the hips to sink excessively, while one that feels too firm may not provide the surface feel they prefer.
A medium to medium-firm mattress may be a useful starting point for many back sleepers, although individual comfort preferences and body weight matter.
What to consider: Choose a mattress that feels comfortable across your back and hips without excessive sinking or uncomfortable pressure.
3. Stomach Sleepers
Stomach sleepers may prefer a firmer-feeling mattress that limits excessive sinking around the midsection.
If the sleeping surface is too soft for your body, your midsection may sink more deeply than you find comfortable. A more supportive-feeling mattress may help you maintain a more comfortable sleeping position.
What to consider: Pay attention to how your midsection rests on the mattress. A surface that feels too soft may not suit your preferences, but the firmest mattress is not automatically the best choice either.
4. Combination Sleepers
Combination sleepers move between different sleeping positions throughout the night. If this sounds familiar, you may need to consider both mattress firmness and how easily you can change positions.
A mattress that feels comfortable on your side may feel different when you roll onto your back or stomach.
What to consider: Look for a balance of cushioning, support and responsiveness that feels comfortable in the positions you use most often. When trying a mattress, spend time moving between positions rather than testing it in just one.
Remember that sleeping position provides guidance rather than a strict rule. The right mattress is the one that accommodates your body and feels comfortable to you.
Does Body Weight Affect the Firmness You Need?
Yes. Body weight can influence how deeply you sink into a mattress and how firm it feels.
A lighter person may experience a mattress as firmer because their body applies less pressure to the sleeping surface. Someone with a higher body weight may compress the same mattress more deeply and experience it as softer.
This is one reason why two people can try the same mattress and have very different opinions about its firmness.
Body weight should be considered alongside sleeping position, mattress construction and personal preference. It is not a reason to automatically choose a particular firmness category.
If you share a bed with a partner, remember that the same mattress may feel different to each of you. Where possible, both sleepers should test the mattress and consider whether it accommodates their individual comfort needs.
How Does Mattress Construction Affect Firmness?
The materials and construction inside a mattress play an important role in how it feels.
Different foam types and combinations of materials can create different levels of cushioning, responsiveness and resistance to compression.
For example, a mattress with a more contouring comfort layer may feel different from one that responds more quickly when you move. The arrangement and characteristics of the materials also influence the overall sleeping experience.
This means that two mattresses labelled as medium-firm may not feel identical.
When comparing mattresses, consider the overall feel rather than relying solely on the firmness description. If possible, test the mattress in your usual sleeping position and give yourself time to assess how comfortable it feels.
What If Your Mattress Feels Too Soft or Too Firm?
If your mattress is not quite as comfortable as you would like, the first step is to identify what is causing the problem.
If Your Mattress Feels Too Firm
If your mattress is still flat and supportive but feels harder than you prefer, a mattress topper may help soften the sleeping surface by adding cushioning.
Memory foam, gel memory foam, latex and convolute toppers each offer different surface feels, so your choice will depend on the type of comfort you prefer.
However, a topper will not change the underlying construction of your mattress or suit every situation.
If Your Mattress Feels Too Soft
If your mattress feels too soft, consider whether it simply has a more cushioned feel than you prefer or whether it no longer provides adequate support.
A topper may change the surface feel, but it is not a reliable way to correct a mattress that allows excessive sinking or has developed significant sagging.
If the mattress is no longer supportive or has deteriorated, replacing it with a more suitable mattress is generally the better option.
The important distinction is between adjusting surface comfort and addressing a mattress that no longer meets your needs.
How Can You Tell If a Mattress Is Right for You?
Choosing a mattress is a personal decision, but a few practical checks can help you assess whether a mattress is a good fit.
Consider these questions when trying a mattress:
-
Does the mattress feel comfortable in your usual sleeping position?
-
Does it provide the level of cushioning you prefer?
-
Do you feel adequately supported without sinking excessively?
-
Can you change positions comfortably if you move during the night?
-
If you share a bed, does the mattress feel suitable for both sleepers?
Avoid choosing a mattress based only on how it feels when you sit on the edge or press your hand into the surface. Lie down in your usual sleeping position and spend enough time assessing the overall feel.
If you are shopping online, read the product descriptions carefully and compare the available firmness options, materials and specifications. Make sure you understand the retailer's applicable delivery, return and exchange conditions before purchasing.
So, Which Mattress Firmness Should You Choose?
There is no single mattress firmness that suits everyone. Your sleeping position can help you narrow down your options, but body weight, mattress construction and personal comfort preferences all play a role.
As a general starting point:
-
Side sleepers may prefer a softer to medium-feeling surface with comfortable cushioning around the shoulders and hips.
-
Back sleepers may prefer a medium to medium-firm feel that balances cushioning and support.
-
Stomach sleepers may prefer a firmer-feeling surface that limits excessive sinking.
-
Combination sleepers may prefer a balanced, responsive surface that feels comfortable across multiple sleeping positions.
These are starting points, not strict rules. The best mattress for you is one that feels comfortable and provides suitable support for your body.
