A double mattress topper is a removable comfort layer designed to sit on top of a standard Australian double mattress, instantly improving comfort, support, and temperature regulation without replacing the mattress itself. In simple terms, it’s an upgrade layer that changes how your bed feels — softer, firmer, cooler, or more supportive — depending on the material you choose.
The main reason Australians love a double mattress topper is its ability to refresh a tired mattress, personalise sleep comfort, and extend mattress life at a fraction of the cost of buying new. Whether you’re dealing with pressure points, overheating, or a mattress that feels too firm, a double mattress topper offers a fast, flexible solution.
Not all double mattress toppers are created equal. Here’s why understanding the types matters before you buy.
Memory foam toppers contour to the body, responding to heat and pressure. They’re ideal for sleepers who want pressure relief around hips and shoulders.
Best for: Side sleepers, joint support, pressure relief
Feel: Soft to medium, body-hugging
Watch for: Heat retention (opt for gel-infused or breathable designs)
Latex toppers offer responsive support with a naturally buoyant feel. They’re popular in Australia for their breathability and durability.
Best for: Combination sleepers, hot sleepers
Feel: Medium to firm, springy
Bonus: Naturally hypoallergenic options available
These toppers deliver hotel-style luxury with plush softness.
Best for: Adding softness to firm mattresses
Feel: Soft, cloud-like
Consideration: Less supportive for those needing spinal alignment
Wool toppers regulate temperature exceptionally well, making them ideal for Australian climates.
Best for: Year-round comfort
Feel: Soft yet supportive
Benefit: Moisture-wicking and naturally temperature balancing
Affordable and lightweight, synthetic toppers are easy to maintain.
Best for: Guest rooms, budget-friendly upgrades
Feel: Soft
Maintenance: Easy to wash and care for
Choosing the right double mattress topper comes down to comfort goals, sleep style, and bedroom conditions.
Ask yourself:
Is my mattress too firm or too soft?
Do I wake up with pressure pain?
Do I sleep hot?
Most double mattress toppers range from 3cm to 10cm.
3–5cm: Subtle comfort adjustment
6–8cm: Noticeable support and softness
9–10cm: Maximum transformation
Soft: Comfort layering for firm mattresses
Medium: Balanced support for most sleepers
Firm: Added structure for sagging mattresses
Australian sleepers should prioritise breathable materials like wool, latex, or ventilated memory foam.
A standard Australian double mattress measures 137cm x 188cm. Always confirm topper sizing for a secure fit.
Here’s why a double mattress topper is one of the smartest bedroom upgrades you can make.
A topper can dramatically improve sleep quality in one night — no breaking-in period required.
By absorbing daily wear, a double mattress topper protects your mattress and delays replacement.
Compared to buying a new mattress, a topper delivers comfort at a lower investment.
Toppers are portable, easy to remove, and perfect for temporary or shared living spaces.
The right topper improves spinal alignment, reducing back and joint discomfort.
