The 5 things to decide before you buy

01

Choose the right size

Your mattress should suit both your room and the way you sleep. If you share a bed, size often matters more than shoppers expect. Many couples are more comfortable stepping up to a queen or king if the room allows.

02

Choose your preferred feel

Think in terms of comfort and support together. A mattress can feel plush on top but still provide strong underlying support. What matters is whether your spine feels aligned and your pressure points feel cushioned.

03

Match the mattress to your sleep style

Side sleepers usually want more pressure relief, while back and stomach sleepers often prefer a flatter, more supportive feel. Couples may also want better motion control.

04

Compare materials honestly

Memory foam, latex, pocket spring, and mattress-in-a-box options all have different strengths. There is no single “best” type for everyone, only the best fit for your body, bedroom, and routine.

05

Think about the full setup

Your bed base, mattress protector, room temperature, and maintenance habits all affect how your mattress performs over time. A good mattress works best as part of a well-matched sleep setup.

Expert

A practical in-store tip

If you can test a mattress in person, lie on it in your usual sleep position for at least 10 to 15 minutes. A mattress can feel comfortable for one minute and still be the wrong choice after a full night’s sleep.

Mattress sizes

Choose a mattress size that suits your room and routine

Australian mattress sizing is straightforward, but the right choice depends on more than dimensions alone. Think about who will sleep on the mattress, how much room you like around you, and whether you want extra space for children or pets joining you from time to time.

Simple rule of thumb: if you are choosing between two sizes and your room comfortably allows it, the larger size is usually the better long-term choice for comfort.

Firmness guide

How to choose the right firmness

Firmness is personal, but comfort should never come at the cost of support. The best mattress is one that helps keep your body well aligned while still feeling comfortable enough to relax into.

Soft to medium-soft

Usually preferred by sleepers who love a plush, cushioned feel. This comfort level can suit lighter bodies and some side sleepers who want gentler pressure relief.

Medium to medium-firm

The most versatile choice for many households. It often balances comfort and support well, especially for couples with slightly different preferences.

Firm

Often chosen by back sleepers, stomach sleepers, and people who prefer a flatter, more supportive sleeping surface. Browse our firm mattresses.

Side sleepers often prefer more pressure relief Back sleepers often like balanced support Stomach sleepers often prefer firmer support Couples often benefit from medium-firm balance
Mattress types

Compare mattress types the smart way

Each mattress construction has its own feel, benefits, and ideal use case. Rather than shopping by trend, choose the material profile that best suits how you sleep and how you want the bed to feel night after night.

Material, support system, and surface feel all influence comfort over time.

Memory foam mattresses

Best for: pressure relief, body contouring, and a more cushioned feel.

Why shoppers choose it: memory foam gently adapts to the body and can feel very comforting for shoulders and hips.

Latex mattresses

Best for: responsive comfort, support, and a more buoyant sleeping feel.

Why shoppers choose it: latex tends to feel more lifted and easier to move on than traditional memory foam.

Consider if: you want comfort with a little more natural spring and responsiveness.

Pocket spring mattresses

Sleep position

Choose a mattress that matches the way you sleep

For side sleepers

Look for pressure relief around the shoulders and hips, with enough support to keep the body aligned. Medium or medium-soft comfort layers are often preferred.

For back sleepers

A balanced feel usually works best: enough cushioning for comfort, with support through the lower back and hips. Medium to medium-firm is often a reliable starting point.

For stomach sleepers

A firmer, flatter feel often helps prevent the hips from sinking too deeply. Support and alignment matter more here than plushness.

For couples

If two people sleep differently, start with a mattress that offers strong overall support and good motion control. Pocket spring and many modern foam constructions are popular because they can reduce partner disturbance while still feeling comfortable for both sleepers.

Budget with confidence

What to focus on beyond the ticket price

A mattress is a long-term purchase, so value matters more than simply choosing the lowest price. Consider support, construction quality, comfort layers, intended lifespan, and whether the mattress suits your bed base and household needs.

Look for practical value

Focus on the mattress type, support system, and how it feels for your body. A mattress that suits you well is often better value than a heavily discounted mattress that is not the right fit.

Plan the full sleep setup

It is also worth budgeting for a quality mattress protector, the right bed base, and supportive bedding essentials to help protect your investment.

Bed base & care

Your bed base and care routine matter more than most people realise

Match your mattress to the right base

The bed base affects both comfort and durability. Slatted bases are popular, but spacing should be suitable for the mattress type so the mattress is evenly supported. If you are updating both at once, it is worth choosing them together.

Protect the mattress from day one

A mattress protector helps defend against spills, dust, and everyday wear while keeping the sleep surface fresher for longer. It is one of the simplest ways to care for a new mattress properly.

Rotate when recommended

Some mattresses benefit from rotation to encourage even wear. Always check the specific care guidance for your mattress, and avoid flipping a mattress unless it is designed to be double-sided.

FAQs

Mattress buying guide FAQs

How do I know when it is time to replace my mattress?

If your mattress is sagging, feels uneven, causes new aches, or no longer feels supportive, it may be time to replace it. Many mattresses are commonly replaced after around 7 to 10 years, depending on quality and use.

What mattress firmness is best for back pain?

There is no universal answer, but many shoppers with back discomfort start by looking at medium-firm to firm options with supportive construction. The best choice is the one that keeps you well aligned and comfortable through the night.

Which mattress is best for side sleepers?

Side sleepers often prefer a mattress with better pressure relief around the shoulders and hips. Medium and medium-soft comfort layers are a common starting point, depending on body type and personal preference.

Is a mattress in a box a good option?

Yes, especially if convenience matters. A mattress in a box can be easier to move into apartments, hallways, and tight rooms, while still offering a wide range of comfort and support options.

Do I need a mattress protector with a new mattress?

Yes. A quality protector helps guard against spills, dust, and everyday wear, and it is one of the easiest ways to keep your mattress in better condition for longer.

Can I use any mattress on any bed base?

Not always. Your mattress should have the right support underneath it, and slat spacing can matter for some constructions. If you are unsure, it is best to choose the mattress and base as a matched setup.

What is the difference between memory foam and latex?

Memory foam is known for contouring pressure relief and a more cushioned feel. Latex typically feels more responsive and buoyant. The better choice depends on whether you prefer a more hugged-in feel or a more lifted one.

Should I test a mattress in store before buying?

If you can, yes. Lying on a mattress in your usual sleep position for 10 to 15 minutes can give you a much better feel for its comfort and support than a quick sit or press with your hand.
