What Is a Mattress and Why Does Choosing the Right One Matter?
A mattress is a padded sleeping surface designed to support your body while you rest. Knowing how to choose a mattress means considering factors such as firmness, mattress type, sleeping position, size, materials, comfort and support.
The right mattress can make your bedroom more comfortable and help create a more inviting sleep environment. Because everyone has different preferences and body shapes, there is no single mattress that is perfect for everyone.
In simple terms, how to choose a mattress comes down to finding the right balance between comfort, support and practicality for the way you sleep.
What Are the Main Types of Mattresses?
Understanding mattress construction is the first step when learning how to choose a mattress.
Innerspring Mattresses
Innerspring mattresses use a network of springs to provide support. They can offer a responsive feel and are available in different firmness levels.
Pocket Spring Mattresses
Pocket springs are individually enclosed, allowing the springs to respond more independently to movement. This construction can provide a combination of support and reduced motion transfer.
Memory Foam Mattresses
Memory foam contours around the body and can create a more cushioned, enveloping feel. It is often considered by people who prefer pressure-relieving comfort.
Latex Mattresses
Latex mattresses can provide a supportive and responsive feel. Natural latex options may also appeal to shoppers looking for particular material preferences.
Hybrid Mattresses
Hybrid mattresses combine two or more technologies, commonly springs with foam or other comfort layers. They aim to combine responsive support with cushioning.
Foam Mattresses
Foam mattresses use foam as the primary support and comfort material. Different foam densities and constructions can produce noticeably different feels.
How Do You Choose a Mattress?
When deciding how to choose a mattress, start with your sleeping habits rather than simply choosing the most expensive option.
1. Consider Your Sleeping Position
Your usual sleeping position is one of the most useful starting points.
Side sleepers may prefer a mattress with enough cushioning to accommodate the shoulders and hips.
Back sleepers often look for a balance between support and comfort that helps maintain a natural sleeping position.
Stomach sleepers may prefer a firmer, supportive surface that does not allow excessive sinking.
If you regularly change positions, a responsive medium-firm mattress may be worth considering.
2. Choose the Right Firmness
Mattress firmness is highly personal.
A soft mattress generally provides a more cushioned feel, while a firm mattress offers a more solid sleeping surface. Medium and medium-firm options sit between these extremes.
Don't assume that firmer automatically means better. The ideal firmness depends on your preferred feel, sleeping position and individual support requirements.
3. Think About Mattress Size
Choose a mattress size that works with both your bed frame and bedroom.
Common Australian mattress sizes include:
- Single
- King Single
- Double
- Queen
- King
- Super King
A Queen mattress is a popular choice for couples, while Double and King Single sizes can work well in smaller bedrooms.
4. Consider Motion Transfer
If you share your bed, consider how much movement is transferred across the mattress.
Pocket springs, foam and hybrid constructions can have different motion-transfer characteristics. If one person moves frequently during the night, a mattress designed to minimise disturbance may be preferable.
5. Consider Temperature and Breathability
Some mattress materials retain more warmth than others.
If you tend to sleep warm, look for mattress constructions designed with ventilation or breathable materials. Your sheets, mattress protector and bedding can also influence the overall sleeping temperature.
6. Check the Mattress Height
Mattress thickness can affect the appearance and proportions of your bed.
A thicker mattress can create a substantial, luxurious appearance, while a slimmer profile may suit minimalist bedroom furniture.
Remember to consider the combined height of your bed frame and mattress before choosing bedding.
7. Review the Materials
Check what the mattress is made from and how its comfort and support layers are constructed.
Look for clear product specifications covering materials, dimensions, firmness and care requirements.
8. Consider the Bed Base
A mattress should be compatible with the base or bed frame on which it will sit.
Check the manufacturer's requirements regarding slats, spacing, foundations and other support structures before purchasing.
What Are the Benefits of Choosing the Right Mattress?
Selecting an appropriate mattress can improve both the practical and aesthetic experience of your bedroom.
Key benefits include:
- Provides appropriate sleeping support
- Creates a more comfortable bed
- Helps suit your preferred sleeping position
- Allows you to choose your preferred firmness

Add tactile materials: Linen-look fabrics, wool, timber and woven accessories can introduce warmth.
-
Use balanced bedside lighting: Matching or complementary lamps can create symmetry.
-
Keep the room uncluttered: Allow the bed to remain the main visual focus.
How to Choose a Mattress: Common Questions
What is the most important factor when choosing a mattress?
Comfort and support should be the primary considerations. Your sleeping position, preferred firmness, mattress size and construction can then help narrow the options.
Is a firm mattress better than a soft mattress?
Not necessarily. Firmness is a personal preference, and the appropriate feel depends on factors such as sleeping position and individual comfort.
What mattress is best for side sleepers?
Side sleepers often benefit from sufficient cushioning around pressure-prone areas while still receiving appropriate support. The ideal firmness varies between individuals.
How often should you replace a mattress?
Mattress lifespan varies significantly according to construction, materials, usage and care. Check the manufacturer's recommendations and assess the mattress regularly for visible deterioration or loss of comfort and support.
Should I replace my bed frame when buying a new mattress?
Not always. If your existing frame is structurally sound and compatible with the new mattress dimensions and support requirements, it may continue to be suitable.
