The right mattress should feel comfortable in your usual sleep position, support your body without excessive sink and suit the way you share your bed. The simplest way to choose well is to start with your sleep habits, then compare construction, firmness, trial terms and warranty details before you buy.
For online shoppers, a generous trial reduces risk. Explore Sleep Republic hybrid mattresses, which pair gel-infused memory foam, natural latex, premium foam layers and individually wrapped pocket springs, then assess the fit at home through the 150-night risk-free trial.
How to choose a mattress for your sleep style
Start with your most common sleep position. It changes where your body needs cushioning and support.
- Side sleepers: Usually need pressure relief around the shoulder and hip.
- Back sleepers: Often look for balanced lower-back support.
- Stomach sleepers: Often prefer a more stable feel through the midsection.
- Combination sleepers: May value a responsive surface for easier movement.
Body weight, pillow and personal preference also affect how a mattress feels.
Firmness and support are not the same thing
Firmness is the first feel of a mattress: soft, medium or firm. Support is how it holds your body as you settle into it.
A soft mattress can be supportive with a well-designed core, while a firmer mattress can be uncomfortable without enough pressure-point cushioning. Look for balance, not simply the firmest option.
When testing, lie in your normal sleep position and notice shoulder, hip and lower-back comfort.
Mattress comparison Australia: compare the main types
Use this high-level comparison to narrow your options, then check each model’s specification.
| Mattress type | Typical feel | Potential strengths | Things to check |
|---|---|---|---|
| Hybrid | Balanced, responsive and supportive | Combines comfort layers with springs; often offers airflow and movement control | Layer materials, spring design, edge support and model-specific firmness |
| Memory foam | Close contouring, slower response | Can cushion pressure points and limit movement transfer | Heat retention, ease of movement and edge stability |
| Latex | Buoyant and responsive | Often feels breathable and easier to move on than slow foam | Latex composition, feel and price |
| Traditional innerspring | Springy with a more direct feel | Familiar support and usually broad price options | Comfort-layer depth, motion transfer and edge support |
Focus on how the complete build suits your body and sleep habits, not one material name.
What to look for in a mattress beyond the label
Before you order, check:
- Comfort layers: What sits closest to your body, and is it designed for cushioning, responsiveness or cooling?
- Support system: Does the mattress use foam, springs or a combination, and how is support described across the surface?
- Edge support: Important if you sit on the edge of the bed, sleep close to it or share a smaller mattress size.
- Motion transfer: Especially relevant for couples with different bedtimes or light sleepers.
- Temperature comfort: Look for breathable materials or construction if you are prone to sleeping warm.
- Mattress height and fit: Confirm the depth works with your sheets, bed frame and existing bedding.
- Care requirements: Check the recommended base, rotation schedule and protector guidance before buying.
Size, sharing and bed-base compatibility
Choose the largest size that fits your room and budget, especially if you share the bed.
For couples, pocket springs may reduce partner disturbance, while edge support can make more of the surface usable.
Check your bed base. The right foundation and centre support can affect comfort, wear and warranty eligibility.

Final mattress buying checklist
Before you commit, make sure you can answer “yes” to these questions:
- Does the mattress suit my main sleep position and preferred feel?
- Is there enough cushioning for my pressure points and support underneath?
- Does the size work for my room, sleep partner and bed base?
- Do I understand the materials, care instructions, trial and warranty terms?
- Can I test it at home long enough to make a confident decision?
A good mattress is a personal fit, not a universal winner. Use this mattress buying guide Australia to narrow the options, then let the trial decide.
FAQs: How to choose a mattress
What is the most important thing to look for in a mattress?
Look for a balance of comfort and support in your usual sleep position. The right mattress should cushion pressure points while keeping your body from sinking or feeling pushed out of a comfortable position.
Should I choose a soft, medium or firm mattress?
Start with your sleep position, body weight and comfort preference rather than the label alone. A trial period is the best way to confirm whether the mattress’s firmness works for you at home.
Are hybrid mattresses good for couples?
They can be, particularly when they use individually wrapped pocket springs designed to reduce movement transfer. Check the specific model’s edge support, comfort layers and trial policy as well.
How long should a mattress trial be?
Choose a trial that gives you enough time to sleep on the mattress in your regular environment. Read the policy for return conditions, pickup arrangements and any location restrictions before ordering.
What should I check before buying a mattress online?
Check the full mattress specifications, size, price, delivery, trial, returns, warranty and care requirements. Also confirm that your bed base provides the support the manufacturer requires.
