How to Choose the Right Mattress in Australia (Complete Buying Guide)

Buying a new mattress in Australia shouldn’t be overwhelming. Yet every week in our Campbelltown, Warrawong and Prospect showrooms we hear the same questions: “How firm should a mattress be?”, “When should I replace my mattress?”, and “Should I go Queen or King?”

This complete mattress buying guide Australia cuts through the confusion. Whether you’re after the best mattress Australia for back pain, hot sleepers, or couples, you’ll learn exactly what to look for before you buy.

1. How firm should a mattress be?

Firmness is the number one factor Australian shoppers get wrong.

Quick firmness guide for Australian sleepers:

Sleeping Position Recommended Firmness Why it works
Side sleepers Medium to medium-soft Relieves shoulder & hip pressure
Back sleepers Medium to medium-firm Keeps spine aligned
Stomach sleepers Medium-firm to firm Prevents hips sinking
Combination Medium Versatile support


Pro tip: In Australia’s warmer climate, medium-firm hybrids often perform best - they offer support without trapping heat.

Too firm? You wake with shoulder/hip pain. Too soft? Your back aches. The goal is neutral spine alignment.

2. When should you replace your mattress in Australia?

Quality Australian mattresses last 7–10 years. Replace sooner if you notice:

  • Waking up sore or stiff
  • Visible sagging or body impressions
  • Rolling toward the middle
  • Better sleep on holiday beds
  • Mattress is older than 8 years

Replacing at the right time improves sleep quality and can reduce back pain.

3. Queen vs King mattress size – which is right for you?

Size Dimensions Best for Room size needed
Queen 153 × 203 cm Couples on a budget Standard bedrooms
King 183 × 203 cm Restless sleepers, kids/pets Larger rooms


Most couples regret not going King when space allows. The extra 30 cm width makes a noticeable difference.

4. Pocket spring vs foam vs hybrid mattresses explained

Type Best for Airflow Motion Isolation Lifespan
Pocket Spring Hot sleepers, strong support Excellent Good 8–10 yrs
Foam (Memory/Latex) Pressure relief, side sleepers Moderate Excellent 7–9 yrs
Hybrid Most Australians (best of both) Very good Excellent 8–12 yrs


Hybrid mattresses are currently the most popular choice across Australia because they deliver support + comfort + breathability.


5. Do you need a new bed base with a new mattress?

Yes in most cases. A sagging or unstable base voids warranties and shortens mattress life.

Check your base if slats are bowed, gaps > 7 cm, or the frame creaks.

Common mattress buying mistakes Australians make

  • Choosing firmness based on a friend’s recommendation
  • Buying the cheapest option (it rarely lasts)
  • Ignoring room size before upgrading to King
  • Keeping an old base under a new mattress
  • Not testing in-store (online photos don’t tell the full story)

Final advice: How to choose the right mattress in Australia

  1. Match firmness to your sleep position and body weight
  2. Choose the right size for your room and lifestyle
  3. Pick hybrid or pocket spring for most Australian conditions

Frequently Asked Questions

How do I choose the right mattress in Australia? +
Start by matching firmness to your sleeping position — side sleepers need medium to medium-soft, back sleepers medium to medium-firm, and stomach sleepers medium-firm to firm. Then choose the right size for your room and your life, and select a construction (pocket spring, foam, or hybrid) that suits your comfort preference and budget. If you can, try before you buy at a showroom.
What firmness mattress is best for back pain? +
Medium to medium-firm is generally recommended for back pain. This firmness supports the natural curve of your spine while relieving pressure points. A mattress that is too soft lets the hips sink and curves the spine, while one that is too firm can create pressure at the shoulders and hips. The right choice also depends on your sleeping position and body weight.
How long should a mattress last in Australia? +
Most quality mattresses last between 7 and 10 years, depending on construction, weight of use, and how it is maintained. Signs you need to replace your mattress include visible sagging, body impressions, waking up sore, or sleeping better elsewhere (the hotel test). A cheap mattress may need replacing sooner — closer to 5 years.
Is a King mattress worth it over a Queen in Australia? +
If your bedroom can fit it, yes — a King is 30cm wider than a Queen (183cm vs 153cm) and makes a significant difference for couples, especially if one partner is restless or you share the bed with children or pets. Queen is the most popular size in Australian homes and suits most rooms. Measure your space before deciding — you need clearance on both sides of the bed.
What is the difference between pocket spring, foam, and hybrid mattresses? +
Pocket spring mattresses have individually wrapped coils that move independently, providing strong support and good airflow — ideal for hot sleepers. Foam mattresses contour closely to the body for pressure relief and motion isolation. Hybrid mattresses combine pocket springs with foam comfort layers, offering a balance of support, comfort, and airflow that suits most couples and body types.
What is the best mattress type for couples in Australia? +
Hybrid mattresses are generally the most popular choice for Australian couples because they combine pocket spring support with foam comfort layers. Pocket springs provide good motion isolation so partners don't disturb each other, and the foam layers add pressure relief. Hot sleepers will also appreciate the airflow that pocket springs allow.
Do I need a new base when I buy a new mattress? +
Not always, but it's worth checking. If your current base has bowed or broken slats, gaps wider than 6–7cm, or is unstable, it can affect the performance and warranty of your new mattress. An old ensemble base under a quality new mattress can also compress unevenly. When in doubt, ask your retailer — a matched base and mattress set is often the better long-term investment.
How much should I spend on a mattress in Australia? +
A good quality mattress in Australia ranges from around $800 to $3,000 for a Queen, depending on construction and brand. Budget options under $500 tend to have shorter lifespans and fewer comfort layers. Spending $1,000–$2,000 on a quality pocket spring or hybrid mattress from a reputable brand typically gives you the best value over its 8–10 year life.
What is the most popular mattress size in Australia? +
Queen (153 x 203cm) is the most popular mattress size in Australian homes. It fits comfortably in most standard bedrooms and suits most couples. King (183 x 203cm) is the next most popular for larger rooms and couples who want more space. King Single is popular for teenagers and taller individuals.
Should I buy a mattress in-store or online in Australia? +
For most people, trying a mattress in-store is the most reliable way to find the right feel — you can test firmness and construction under your actual body weight. Online purchasing is convenient and often comes with sleep trials of 100 nights or more. If you're buying online, look for a generous sleep trial so you can return it if it isn't right. Best in Beds has showrooms in Campbelltown, Warrawong, and Prospect where you can test a wide range.
