Choosing the right mattress isn’t always easy — especially with so many different options, sizes, and firmness levels on the market. But the truth is, your mattress can make or break your sleep quality — and even your daily energy levels.
At Bedzy, we’ve helped thousands of Australians find the perfect mattress for their needs. Whether you’re shopping for back support, better pressure relief, or simply a more luxurious night’s sleep, this guide will walk you through exactly how to choose the right mattress — and avoid common mistakes.
Step 1: Know Your Sleeping Position
Your preferred sleeping position should be one of the first things you consider when shopping for a mattress:
-
Back Sleepers: A medium-firm to firm mattress (6.5/10 to 7.5/10) is often ideal for proper spinal alignment
👉 Explore 6.5/10 Medium Firm Mattresses
👉 Explore 7/10 Medium Firm Mattresses -
Side Sleepers: Typically need a bit more cushioning for hips and shoulders
👉 Explore Medium Mattresses 5/10
👉 Explore 6/10 Medium Firm Mattresses -
Stomach Sleepers: Require a firmer surface to avoid lower back arching
👉 Explore Extra Firm Mattresses (9/10) -
Combination Sleepers: Need balanced support — medium-firm is usually the safest bet
Step 2: Pick the Right Thickness
Thicker doesn’t always mean better — but when it comes to comfort and durability, we recommend choosing a mattress at least 32cm thick, especially for adults or couples.
A thicker mattress:
-
Provides better body contouring
-
Handles more weight without sagging
-
Offers deeper pressure relief
-
Feels more luxurious — like a proper night’s sleep, not a camping trip

Step 3: Choose the Right Size for Your Space
Don’t just measure your mattress — consider the total space you’ll need with a bed frame, bedside tables, and room to walk.
We stock every standard Australian size:
Still unsure? Go one size up. Few people ever regret buying a bigger bed.
Step 4: Consider Cooling, Motion Isolation & Support
Depending on your lifestyle or sleep habits, it’s worth considering these extra features:
-
Cool Gel Layers: Perfect for hot sleepers
-
Pocket Springs: Reduce partner disturbance
-
Euro Top or Pillow Top: Adds plush comfort on top of firm support
-
Edge Support: Important if you sit or sleep near the edge
Many of our mattresses include all of the above — and you can filter by feature on our collection pages.
