The Best Mattress Toppers in Australia for 2026: Complete Guide

Mattress toppers are the secret weapon of the sleep world. Just like the perfect sauce makes a sundae, the best mattress topper will take your bed to the next level. A great topper can add enough softness, support, or cooling to jazz up an uncomfortable mattress without the expense of buying a whole new bed.

 

Because there are so many kinds of mattress toppers, we've tested and categorized a broad range. Memory foam and latex toppers are dense enough to support body weight, while bamboo and gel options are a dream in hot Australian climates.

 

Here is our comprehensive guide to the best mattress toppers in Australia, categorized by what they do best.

Our Review of Australia's Best Mattress Toppers

Best Overall — Eco Toppers Bamboo Mattress Topper

Highlights

  • Features 7 distinct zones of varying firmness to perfectly align the spine.
  • High-density memory foam provides deep pressure relief without excessive sinking.
  • Includes a removable, machine-washable bamboo cover for hygiene and cooling.

We love this 7-Zone Topper because it ticks all the boxes at a great price. It utilizes advanced zoning technology to provide targeted support—firmer under the heavy hips and lower back, and softer under the shoulders and legs.

 

During our testing, this topper excelled at reducing partner disturbance. The dense memory foam absorbed motion beautifully; we measured a motion transfer distance of just 7cm, meaning you won't feel your partner tossing and turning. It also firmed up the edges of our test mattress slightly, providing better stability when getting in and out of bed.

Based on Our Review

This is the most versatile topper on our list. It strikes the perfect balance between the contouring "hug" of memory foam and the structural support needed to prevent back pain. The bamboo cover also ensures it sleeps cooler than traditional memory foam.

Pros

  • Exceptional spinal alignment for all sleep positions
  • Great motion isolation for couples
  • CertiPUR-US certified foams (no harmful chemicals)

Cons

  • Takes 24-48 hours to fully expand and off-gas

Best for Side Sleepers: 8cm Plush Gel Memory Foam Topper

Highlights

  • Generous 8cm thickness provides maximum depth for hips and shoulders to sink into.
  • Plush density foam specifically designed to eliminate pressure points.
  • Gel-infusion helps dissipate the heat that thick foam typically traps.

If you're a side sleeper, you'll find you sink into the mattress more as your weight is narrowly concentrated on your hips and shoulders. Added pressure from side sleeping means you need a softer, thicker topper than back or stomach sleepers. This 8cm Plush Topper is the side sleeper's best bet.

 

In our sinkage tests, this topper allowed for 5.5cm of compression at the heaviest points. This deep cradling completely eliminated the push-back against the hip bone that causes tossing and turning. Despite the deep sinkage, the gel infusion kept the surface temperature at a comfortable 29.1 degrees Celsius.

Based on Our Review

This topper feels like sleeping on a supportive cloud. It completely transformed a rock-hard test mattress into a plush sanctuary. It is the ultimate solution for side sleepers waking up with numb arms or sore hips.

Pros

  • Maximum pressure relief for joints
  • Completely masks a mattress that is too firm
  • Gel infusion prevents overheating

Cons

  • Too soft for stomach sleepers
  • Can make it slightly harder to roll over

Best Plush/Hotel Feel: 1000GSM Bamboo Microfibre Topper

Highlights

  • Filled with 1000GSM of down-alternative microfibre for a fluffy, cloud-like feel.
  • Encased in a 100% bamboo cover that is highly breathable and silky soft.
  • Fitted skirt design stretches over your mattress like a fitted sheet to stay perfectly in place.

If you don't like the dense, sinking feeling of memory foam but want to add a luxurious, 5-star hotel feel to your bed, this high-GSM microfibre topper is the answer. It acts as a massive pillow-top for your mattress.

 

Unlike foam, this topper is highly breathable and machine washable. The bamboo cover wicks away moisture, making it an excellent choice for hot sleepers. While it doesn't offer the structural spinal support of foam or latex, it provides an unbeatable initial layer of soft, airy comfort.

Based on Our Review

This is the best budget-friendly way to make a firm mattress feel luxurious. It's hypoallergenic, dust-mite resistant, and completely free from animal products (a great down alternative). It's like sleeping on a marshmallow.

Pros

  • Creates a fluffy, luxurious hotel-bed feel
  • Highly breathable and machine washable
  • Very affordable price point

Cons

  • Requires occasional fluffing to maintain loft
  • Doesn't provide structural support for back pain

What Makes a Good Mattress Topper?

Thickness

A good topper should be at least 5cm (2 inches) thick. Anything thinner acts more like a mattress protector and won't significantly change the feel of the bed. 5cm is good for general comfort, while 8cm is best for side sleepers or reviving very hard beds.

Material Density

For foam toppers, density matters more than thickness for support. High-density foam (often found in 7-zone or orthopedic toppers) will support your spine, while low-density foam will just feel soft and mushy.
