Memory Foam Mattress Topper Guide

Your complete Australian guide to memory foam — pressure relief, spinal support, and finding the right density for your sleep style.

Why Choose a Memory Foam Mattress Topper?

If your current mattress feels too firm, is showing its age, or simply lacks that extra layer of comfort, a memory foam mattress topper is one of the most effective upgrades you can make. Originally developed by NASA to cushion astronauts during space flight, memory foam has since revolutionised the way the world sleeps.

Memory foam works by responding to your body heat and weight, contouring precisely to your unique shape. This means it doesn't just add softness — it actively supports your spine, redistributes pressure away from painful joints, and reduces the motion transfer that can disturb a partner's sleep.

Who Benefits Most from Memory Foam?

  • Side sleepers needing cushioning at the hips and shoulders
  • Back pain and lower back pain sufferers
  • People with hip pain, bursitis, or arthritis
  • Couples where one partner moves frequently during the night
  • Fibromyalgia sufferers who need gentle, even pressure relief
  • Anyone whose mattress has become too firm over time

The Key Benefits of Memory Foam

Memory foam excels in three core areas that matter most to sleepers. Select a benefit below to learn more.

Pressure Relief Pressure Relief & Joint Support

Memory foam excels at distributing your body weight evenly across the sleep surface. Instead of allowing your heaviest points — hips, shoulders, and lower back — to bear the full load, memory foam spreads that weight across a larger area, eliminating the sharp pressure points that spring mattresses can create.

This is particularly transformative for side sleepers, whose hips and shoulders bear disproportionate pressure in that position. A memory foam topper allows those joints to sink gently into the surface while supporting the rest of the body, reducing the aches and stiffness that can come from sleeping on a surface that's too firm.

Motion Isolation Motion Isolation for Couples

If you share your bed with a restless partner, a memory foam topper can be genuinely life-changing. Memory foam is highly effective at absorbing kinetic energy — when your partner tosses, turns, or gets in and out of bed, the movement is largely contained to their side rather than rippling across to yours.

This motion isolation effect is one of the most significant differences between memory foam and traditional spring or latex surfaces. For light sleepers who are easily disturbed by a partner's movement, adding a memory foam layer to an existing spring mattress can make a dramatic difference to sleep quality.

Back Pain Back Pain & Spinal Alignment

Memory foam is one of the most recommended materials by sleep specialists for back pain sufferers. Its body-contouring properties allow it to support the natural curves of your spine — filling the lumbar gap that a firmer surface leaves unsupported — while still cushioning areas that don't need as much pushback.

For lower back pain specifically, a medium-firm memory foam topper tends to work best. It provides enough resistance to prevent the hips from sinking too deeply (which would force the spine out of alignment), while still offering the pressure relief that makes sleep comfortable. A thickness of 5-7cm is generally ideal for back pain relief.

Firmness Customisable Firmness & Feel

One of the great advantages of memory foam toppers is the range of densities available, allowing you to fine-tune your sleep surface rather than replacing your entire mattress. If your bed feels too firm, a softer, high-loft memory foam topper adds a cloud-like plush layer. If your mattress lacks support, a high-density option provides firmer, more restorative pushback that keeps your spine properly aligned.

Memory foam also has a characteristic "hug" feel — as it warms to your body temperature, it softens and contours. This sensation varies by density: lower-density foams respond quickly and feel softer, while higher-density foams respond more slowly and offer a more supportive, less sink-in feel.

Types of Memory Foam Toppers Explained

Not all memory foam is the same. Here's a breakdown of the most popular types available at Sleep Solutions, so you can choose the right one for your needs.

High Density Foam
Most Supportive

High-Density Memory Foam

A high-density memory foam topper offers exceptional durability and firm, robust support. The denser the foam, the longer it resists compression and the more supportive it feels. High-density foam is slower to respond to body heat, giving it that signature "sink in gradually" feel.

This is the ideal choice for back and stomach sleepers who need to maintain a neutral spine, heavier individuals who need more support, and anyone who finds standard foam too soft or short-lived.

Gel Memory Foam
Best for Hot Sleepers

Cooling & Gel-Infused Memory Foam

Traditional memory foam's biggest drawback is heat retention — it can feel warm, particularly during Australian summers. Cooling memory foam addresses this by infusing the foam with gel beads or graphite particles that actively draw heat away from the body.

Graphite-infused memory foam is one of the most advanced options available, offering excellent thermal conductivity alongside all the pressure-relief benefits of standard memory foam. If you love the feel of memory foam but tend to sleep hot, gel or graphite-infused is the smart upgrade.

Egg Crate Foam
Best Value

Egg Crate / Convoluted Foam

An egg crate (or convoluted) foam topper features a distinctive textured surface with a pattern of peaks and valleys. This clever design serves two purposes: it promotes maximum airflow through the topper, and it provides targeted pressure relief at the contact points between your body and the surface.

Egg crate toppers are typically the most affordable memory foam option and are a popular choice for guest beds, caravans, and everyday comfort upgrades. They offer a noticeably different feel to flat foam — lighter and more breathable, with a gentle contouring effect.

Premium Memory Foam
Premium Range

Premium & Luxury Memory Foam

At the top end of the memory foam range sit premium toppers engineered for maximum comfort and longevity. These typically feature higher-density foam constructions, advanced cooling technologies, and superior cover materials — often bamboo or Tencel for added breathability.

Premium memory foam toppers are designed for sleepers who want the full body-moulding, pressure-relieving experience every night, and who want a topper that will maintain its properties for many years. If you've ever tried a high-end memory foam mattress and want that feel without the full price tag, a premium topper is the closest you'll get.

How to Choose the Right Memory Foam Topper

Keep these practical considerations in mind when shopping, and you'll find the right match much more quickly.

Thickness & Density

Thickness determines how dramatically the topper changes your sleep experience. Density determines firmness and durability. These two factors work together — a thicker, denser topper lasts longer and makes a bigger difference.

Thickness Guide
5 cm — Subtle improvement; best for mattresses in good condition needing light softening
7 cm — Noticeable difference; ideal for pain relief and pressure point reduction
10 cm — Dramatic transformation; effectively masks an ageing or uncomfortable mattress

Firmness by Sleep Position

Your sleep position is the single most important factor in choosing the right firmness. Getting this right makes all the difference to how well memory foam supports your spine and relieves pressure.

Firmness Guide
Soft / Medium-Soft — Side sleepers; allows hips and shoulders to sink in comfortably
Medium — Combination sleepers; balanced support and pressure relief for most positions
Medium-Firm / Firm — Back and stomach sleepers; maintains neutral spinal alignment

Fit & Secure Attachment

A memory foam topper that shifts during the night will disrupt your sleep and wear unevenly. Make sure you're getting a topper that's sized correctly and stays put.

What to look for
Corner straps — Elastic straps anchor the topper to your mattress corners and prevent sliding overnight
Exact sizing — Always match the topper to your mattress size; overhanging edges compress unevenly
Removable cover — A zippered, machine-washable cover makes hygiene maintenance far easier

Memory Foam vs Other Topper Types

Understanding how memory foam compares to the alternatives will help you decide if it's the right choice for your needs.

Frequently Asked Questions

What is a Memory Foam Mattress Topper?

A Memory Foam Mattress Topper is a specialised bedding accessory designed to provide additional comfort and support for your sleep. It's a layer of memory foam, a unique type of material developed by NASA in the 1960s, which you can place on top of your existing mattress. Memory foam is known for its ability to mould to your body shape in response to heat and pressure, providing a supportive cradle that can help align your spine and alleviate pressure points.

The thickness and density of a Memory Foam Mattress Topper can vary, affecting how it feels. Typically, thicker toppers offer more cushioning, while higher density toppers provide more support. A Memory Foam Mattress Topper is an affordable way to upgrade your bed without investing in a brand-new mattress, and it can extend the life of your existing mattress. These toppers also come in all standard bed sizes to suit a range of bedding needs.

Does a Memory Foam Mattress Topper help back pain?

Yes. Memory foam conforms to your body shape, distributing weight evenly and relieving pressure on the spine, hips, and shoulders. A firm or high-density memory foam topper (50 kg/m³ or above) is generally recommended for back pain, as it provides support without excessive sinking.

A Memory Foam Mattress Topper can indeed be a useful tool for individuals suffering from back pain. The key benefit of memory foam is its ability to conform to the contours of your body. This 'body-hugging' feature enables it to provide personalised support to your back, helping to maintain spinal alignment while you sleep. Maintaining proper spinal alignment is crucial in managing and preventing back pain. Also, the pressure-relieving properties of memory foam can reduce stress on sensitive areas, potentially leading to less discomfort.

  • Memory foam responds to heat and pressure, moulding to your body shape
  • Provides personalised support to maintain spinal alignment
  • Reduces pressure on sensitive areas to alleviate discomfort


However, it's important to remember that not all Memory Foam Mattress Toppers are created equal. The thickness and density of the topper play a significant role in the level of comfort and support it provides. Typically, a higher density topper may offer better support, which could be more beneficial for individuals with back pain. Also, it's worth noting that while a Memory Foam Mattress Topper can help with back pain, it's not a cure-all and should be used in conjunction with other pain management strategies recommended by health professionals.

Does a Memory Foam Mattress Topper make you sweat?

Memory Foam Mattress Toppers, while celebrated for their comfort and support, have been known to make some people feel hotter during sleep. The reason behind this is that memory foam is a dense material that tends to retain heat. When you lay on it, your body heat gets trapped in the foam, which may lead to an increase in your body temperature and potentially cause you to sweat. This issue is more pronounced in traditional memory foam. Here are some reasons:

  • Memory foam is a dense material which traps heat
  • Your body heat can get retained in the foam
  • Traditional memory foam is more prone to heat retention


However, many mattress topper manufacturers are now addressing this issue by incorporating cooling technologies into their products. These may include gel-infused memory foam, open-cell structure memory foam, or memory foam layered with cooling materials like copper or graphite. These designs aim to enhance breathability and dissipate heat, creating a cooler sleep environment. Therefore, if you're considering a Memory Foam Mattress Toppper but are concerned about sleeping hot, look for options that feature cooling technologies.

Do Memory Foam Mattress Toppers sleep hot?

Traditional memory foam can retain heat, but modern cooling technologies solve this. Gel-infused memory foam, open-cell foam, and copper-infused options all improve airflow and heat dissipation. If you're a hot sleeper, choose a gel memory foam topper or pair a standard topper with a bamboo mattress protector.

What thickness Memory Foam Topper is best?

For light cushioning and pressure relief, 4-5 cm is sufficient. For significant comfort improvement or back pain relief, 7-8 cm provides deeper contouring. If your mattress is very firm or worn out, 8 cm+ will make the biggest difference. Higher density foam provides better support at any thickness.
