Choosing a mattress comes down to eight things: the right size, the right firmness for how you sleep, proper support for your back, a build that copes with Darwin’s heat, a construction that suits you, your partner, your budget, and trying it before you buy. This guide walks through each step in order, with links to our more detailed guides wherever you want to go deeper.
Step 1: Pick the Right Size
Start with size, because it narrows everything else. Most couples choose a queen or a king, adults sleeping alone often go for a king single or a double, and children usually start in a single. Check your room and the way into the house as well. Our Australian bed and mattress size chart lists every size in centimetres, and our queen vs king guide helps couples decide between the two biggest sizes.
Step 2: Match the Firmness to How You Sleep
Firmness is how the surface feels when you first lie down. The right level depends mostly on your sleep position and your body weight:
- Side sleepers often do best on a medium to medium-firm feel, so the shoulder and hip can sink in a little while the spine stays straight.
- Back and stomach sleepers usually need a firmer surface to stop the hips dropping too far.
- Heavier sleepers press further into a mattress, so they tend to need firmer support than lighter sleepers.
- Lighter sleepers can find a very firm mattress uncomfortable, because there is not enough weight to soften the surface.
Combination sleepers, and couples who sleep differently, often settle on medium-firm as the middle ground. If you already know you need extra support, our firm mattress guide explains what firm really means and which beds give it.
Step 3: Put Support Ahead of Softness
Support and firmness are not the same thing. Support is how well the mattress holds your spine in a natural line all night, while firmness is simply how the surface feels. A very firm mattress can still support you badly, and a medium mattress can support you well.
If you have back pain, look for zoned support, where the middle of the mattress is firmer under your hips and lower back. Be wary of the word “orthopaedic” on its own: there is no regulated definition in Australia, as we explain in what an orthopaedic mattress actually means. If you work long physical shifts, our guide to recovery sleep and back pain for FIFO workers covers what the research says, and you can see our orthopaedic mattress options here.
Step 4: Plan for Darwin’s Heat
In the Top End, how a mattress handles heat matters as much as how it feels in the showroom. The construction that keeps air moving all night is a pocket spring core, because the gaps between the springs let air circulate every time you move. Breathable covers help too, along with a comfort layer that is not so thick it smothers the springs.
Gel memory foam feels cool to the touch and works best as a layer on top of pocket springs rather than in a solid foam mattress. Our guides to what actually keeps you cool and gel foam vs latex vs pocket springs go into the detail.
Step 5: Choose a Construction
Most mattresses fall into one of four types:
- Pocket spring: individually wrapped coils that move independently, giving good airflow, good support and less movement passed between partners.
- Bonnell or ortho coil: connected springs with a firmer, more traditional feel.
- Hybrid: a memory foam or latex comfort layer over a pocket spring core, combining pressure relief with airflow.
- All-foam: quiet and good at soaking up movement, but it holds more heat than a mattress with a spring core.
In our range, the Calm and the Active sleepVITAL are hybrids that pair gel memory foam with pocket springs, while the Solace uses ortho coil springs in a firm build. Our memory foam mattress page compares foam and springs in more detail.
Step 6: Think About Your Partner
If you share a bed, look at motion transfer and edge support. Pocket springs and memory foam both absorb movement, so one person rolling over is less likely to wake the other. Firm edges give you more usable sleeping space and make it easier to sit on the side of the bed. If you sleep very differently, a medium-firm feel is often the best compromise, and a king gives each of you about 91.5 cm of width.
Step 7: Set Your Budget
Price usually follows the materials: deeper comfort layers, more springs and zoned support all cost more. Decide what you want to spend before you start, then compare within that range. Our affordable range covers well-made beds at lower prices, and our premium range steps up the support and materials. If you would rather spread the cost, Afterpay and Payright are available.
Step 8: Try It Before You Buy
Firmness and support are hard to judge from a product page and easy to judge lying down. Lie on each mattress for at least 10 minutes in the position you actually sleep in, and bring your partner if you share a bed. Our guide to the hidden cost of buying a mattress online without trying it first explains why this matters.
At our showroom in Jape Homemaker Village, Millner, open 7 days, a free sleep consultation takes about 20 to 30 minutes. We ask how you sleep and what you want to spend, then let you compare firmness levels and constructions side by side. Book a free mattress fitting or call us on 0404 229 933.
When Is It Time to Replace Your Mattress?
There is no fixed number of years. How long a mattress lasts depends on its materials, your body weight and Darwin’s climate. The signs to watch for are sagging or body-shaped dips, springs you can feel through the top, and waking up stiff or sore when you went to bed feeling fine. Our guide on how long a mattress really lasts explains what to look for.
Frequently Asked Questions
How do I choose the right mattress firmness?
Start with your sleep position and body weight. Side sleepers usually suit medium to medium-firm, back and stomach sleepers usually need firmer support, and heavier sleepers generally need a firmer mattress than lighter sleepers. Trying a few firmness levels in person is the most reliable test.
Which mattress is good for back pain?
Look for a mattress that keeps your spine in a natural line, usually a medium-firm to firm build with zoned support under the hips and lower back. The right level depends on your body and sleep position, so it is worth trying a few options in person.
What is a hybrid mattress?
A hybrid mattress combines a pocket spring core with a comfort layer of memory foam or latex on top. The springs provide support and airflow, and the foam or latex adds pressure relief. In a hot climate like Darwin’s, the spring core helps it sleep cooler than an all-foam mattress.
What is the best mattress in Australia?
There is no single best mattress for everyone. The best one for you depends on your size, sleep position, body weight, how hot you sleep and your budget. Work through the steps above, then try your shortlist in person.
How long should a mattress last?
It depends on the materials, your body weight and the climate rather than a fixed number of years. Replace it when it sags, shows body impressions or leaves you waking up sore.
