Best Mattress Toppers in Australia 2026 — Upgrade Your Sleep Without a New Mattress

Here is a sleep secret most people discover too late: you do not always need a new mattress. What you often need is a good mattress topper. A quality topper can transform a too-firm mattress into something that feels like a luxury hotel bed, add pressure relief to an ageing mattress, or simply extend the life of a perfectly serviceable mattress that is starting to feel a little flat.

Australian consumers spend an average of $1,200–$3,000 on a new mattress. A quality mattress topper costs $80–$400, and in many cases it delivers the same improvement in sleep quality at a fraction of the cost. The key is matching the right topper type and thickness to your sleep position, body weight, and temperature preferences.

We have tested and researched every major mattress topper category available in Australia — memory foam, gel foam, latex, and down — and we will walk you through exactly what to buy and why.

When You Need a Mattress Topper vs a New Mattress

A mattress topper is the right solution when your mattress is structurally sound but the comfort layer has degraded or never quite suited you. If your mattress has visible sagging, is more than 8–10 years old, or has a coil system that is starting to creak and poke, a topper is a temporary fix at best — you need a new mattress.

A mattress topper is the right solution when:

• Your mattress is too firm and causing pressure points on your hips or shoulders
• Your mattress feels slightly too flat or has lost its original plushness
• You are sleeping hot and want to add a cooling layer without replacing the whole mattress
• You want to protect a new mattress and extend its lifespan
• You have a guest room mattress that needs a temporary quality boost

If you are waking with back pain, the cause could be either a mattress that is too soft (not enough support) or too firm (pressure on the lumbar area). A mattress topper can fix the too-firm problem by adding a plush comfort layer. It cannot fix a too-soft problem — adding more softness on top of an already soft mattress makes the problem worse.

Memory Foam vs Latex vs Down vs Wool

The four main mattress topper materials each have distinct characteristics that suit different sleepers.

Memory Foam

Memory foam is the most popular topper material in Australia. It moulds to the contours of your body, distributing weight evenly and relieving pressure points — particularly at the hips and shoulders for side sleepers. The downside: traditional memory foam traps heat. Manufacturers have addressed this with gel-infused memory foam (gel beads blended into the foam to absorb heat), open-cell foam (larger cell structure allows more airflow), and graphite-infused foam. If you sleep warm, look for gel-infused memory foam rather than standard.

Memory foam toppers are rated by density (kg/m3). Higher density means longer-lasting, more supportive foam. Budget toppers are typically 25–35 kg/m3 and will compress and lose their shape within 2–3 years. Quality toppers are 50–80 kg/m3 and last 4–7 years.

Latex

Latex is the premium option. Natural latex (made from rubber tree sap) is more breathable than memory foam, more responsive (it springs back immediately rather than slowly recovering), and far more durable — a quality latex topper lasts 10–15 years. Talalay latex is the premium sub-type, made by a more complex manufacturing process that produces a more consistent, softer, and more breathable product than Dunlop latex.

Latex is also naturally hypoallergenic and dust mite resistant — important for allergy sufferers. The only downside is cost: quality natural latex toppers start around $350–$400 for a queen size.

Down and Feather

Down and feather toppers (sometimes called mattress overlays or featherbeds) add a plush, cloud-like softness. They are not supportive — they do not relieve pressure points or change the firmness of your mattress in any meaningful way. What they do is add a luxurious top layer that feels wonderful to climb into. If your mattress is already comfortable but you want that hotel-bed feeling, a down topper adds that. If you need pressure relief or have back issues, choose memory foam or latex instead.

Down toppers are not suitable for allergy sufferers and can trigger asthma. They also require careful washing — most need dry cleaning or large commercial machines.

Wool

Wool toppers are less common but excellent for Australian conditions. Wool is naturally temperature-regulating — it wicks moisture and keeps you warm in winter, cool in summer. It is less pressure-relieving than memory foam but adds a natural, sustainable comfort layer. Quality Australian wool toppers are available for $150–$300 and are a good choice for hot sleepers who find memory foam too warm.

Best Budget Mattress Toppers Under $150

At the budget end, you are primarily looking at memory foam toppers from brands like Giselle, Graysonline, and various Amazon-direct brands. The quality varies considerably, and at this price point you are accepting some compromises on density and longevity.

The Giselle Memory Foam Topper 8cm is the best-selling budget option in Australia and for good reason. At 8cm thick, it adds meaningful plushness to a firm mattress — more so than the 5cm toppers that are common at this price point. The bamboo cover is breathable and hypoallergenic, and it is available in every standard Australian mattress size. At 25 kg/m3 density it will not last as long as a premium topper, but for a guest room, a rental property, or a first home on a tight budget, it does the job reliably.

Best Mid-Range Mattress Toppers ($150–$300)

The $150–$300 bracket is where the quality jump becomes significant. You are getting proper gel-infused memory foam, removable and washable covers, and meaningful warranty coverage.

The Giselle Bedding Bamboo Pillowtop Topper is the standout pick from the dominant bamboo-topper brand on Amazon AU. The pillowtop construction with bamboo cover sleeps noticeably cooler than standard memory foam, and the cover is removable and machine washable — which matters more than people realise: a mattress topper cover that cannot be washed collects skin cells, dust mites, and moisture over time. At around $250 for queen, it sits well below the price of direct-to-consumer alternatives without giving up much on quality.

Also worth considering in this range: the Ecosa Mattress Topper (direct-only Australian brand with a 100-night trial) and the Emma Mattress Topper, which uses a clever two-zone construction with softer foam at the shoulder area for side sleepers.

Best Premium Mattress Toppers ($300+)

Above $300, natural latex becomes the main option, and it is here that the longevity argument becomes compelling. A $400 latex topper that lasts 12 years costs $33 per year. A $90 memory foam topper that needs replacing every 2–3 years costs $30–$45 per year. Premium is not always more expensive in the long run.

The Dunlopillo Talalay Latex Topper is the benchmark for premium toppers in Australia. Dunlopillo has been making latex mattress products since 1929 and their Talalay process produces some of the most consistently high-quality latex available. The pinhole design creates a network of channels through the latex that allows air to circulate continuously — this is why latex sleeps significantly cooler than memory foam despite being a denser material. Naturally resistant to dust mites and hypoallergenic without any chemical treatments, making it the best choice for allergy sufferers who want pressure relief without synthetic foam.

Best Mattress Toppers for Side Sleepers

Side sleeping is the most common sleep position in Australia and the most demanding on a mattress topper. Side sleepers put concentrated pressure on the hip and shoulder — the two points where the body is widest. Without adequate pressure relief at these points, you will wake with hip or shoulder pain regardless of how comfortable the mattress feels to lie on initially.

For side sleepers, the priority is a topper that is soft enough to allow the hip and shoulder to sink in while still supporting the waist. Memory foam and soft latex are the best choices. Aim for at least 7–10cm of memory foam thickness, or a soft (ILD 20–24) latex topper. Avoid wool and feather toppers for side sleeping — they do not provide the contouring pressure relief side sleepers need.

Gel memory foam is particularly well-suited to side sleepers who are also warm sleepers, as it combines the pressure-relieving properties of memory foam with better heat dissipation.

Best Mattress Toppers for Hot Sleepers

Sleeping hot is a widespread problem in Australia, especially in Queensland, Western Australia, and New South Wales during summer. If you regularly wake up sweating or find yourself pushing blankets off through the night, your mattress topper material matters significantly.

The hierarchy for hot sleepers: natural latex (most breathable) then gel memory foam then wool then standard memory foam. Avoid standard memory foam entirely if you are a hot sleeper — it traps body heat and makes the problem considerably worse.

Beyond material, look for toppers with a bamboo or Tencel cover rather than polyester. Bamboo and Tencel are far more moisture-wicking and feel cooler against skin. Toppers with ventilation channels — either pinholes in latex or channelled cuts in memory foam — also improve airflow significantly.

Frequently Asked Questions

How thick should a mattress topper be?

For most sleepers, 5–8cm provides the sweet spot between comfort and support. Thinner toppers (2–4cm) add minimal softness and are best for protecting a good mattress rather than transforming a bad one. Thicker toppers (10cm plus) add significant plushness but can make the sleep surface feel unstable, especially for heavier individuals. Side sleepers and those with joint pain benefit most from 7–10cm. Stomach sleepers should avoid very thick, soft toppers as they can cause lower back pain by allowing excessive lumbar sinking.

Can I put a mattress topper on a memory foam mattress?

Yes, but it is worth asking why. If your memory foam mattress is relatively new and structurally sound, a topper can add a cooling layer or adjust firmness. If your memory foam mattress is old and has developed body impressions, a topper can mask the problem but will not fix the underlying support issue. Adding a latex topper to a memory foam mattress is a popular combination — you get the responsive feel of latex on top with the deep pressure relief of memory foam below.

How do I keep a mattress topper from sliding?

Most toppers come with elastic corner straps that hook around the mattress corners — use them. If your topper does not have straps, you can buy mattress topper straps separately for around $15–$25. A fitted mattress protector placed over the topper also helps hold it in place. Alternatively, choose a topper with a non-slip base — some latex and wool toppers have textured bases that grip the mattress surface without straps.
