Does your old mattress not feel as comfortable or soft as it did before? Well, it’s time that you got a new memory foam mattress.

If you have shopped for mattresses before, you might have come across the term memory foam. It is a material that has viscoelastic properties - meaning that it effectively adjusts to the contours of your body when you sleep on it. And after the load is removed, it returns to its original shape.

When it comes to softness, memory foam mattresses are probably the best type of mattress that you can get. These mattresses provide exceptional cushioning, which provides relief from pressure and gives you a comfortable sleeping environment.

However, when you go looking for a good mattress, you might feel confused by the different specifications and technical aspects. That is why we have done the hard work for you in this informative review-based guide so that you can choose with ease.

Let’s dive in!

Some of the Best Memory Foam Mattress in Australia are:

  1. Emma Comfort Mattress - Top Pick
  2. The Koala Mattress
  3. Hesperis Mattress
  4. Onebed Original Mattress
  5. Ergoflex 5G Memory Foam Mattress

1. Emma Comfort Mattress

The Emma Comfort Mattress is one of the best memory foam mattresses that you can get. This all-foam mattress consists of 4 layers with a collective thickness of 25 cm. Thus, it gives you excellent medium-firm comfort. What’s more, the memory foam is soft enough to hug your curves perfectly so that you get optimal pressure relief. Despite the softness, it eliminates motion transfer to give you a peaceful sleep.

In terms of breathability, the mattress features the unique Airgocell memory foam layer, which along with the elastic top cover, effectively dissipates heat and absorbs sweat. The HRX layer provides a healthy spinal alignment, which makes it suitable for all sleeping positions - front, back or side. As a bonus, the outer cover of this mattress is entirely removable, so maintaining the mattress is a breeze.


The soft foam layers may be relatively uncomfortable if you are a heavy sleeper.


Overall, this is a great memory foam mattress that is both high quality and affordable, thanks to its premium design and materials. And it comes with an OEKO-Tex certification, which means that besides being supportive and comfortable, this mattress is pretty safe too.

2. The Koala Mattress

The Koala mattress is a popular choice among consumers due to its quality and adjustability. Its top layer comes with a double-sided zipper design which allows you to flip between two different firmness levels easily. Besides the adjustable firmness, the top layer is highly breathable as well, thanks to the unique TENCEL Lyocell fabric. Plus, the firmer support base gives you comfortable pressure relief without sinking in too much.

This mattress features an anti-slip bottom surface, which prevents movement on slippery surfaces. Additionally, the materials used for making this mattress are treated with antibacterial additives so that you get a clean and hygienic sleeping environment. Apart from that, the mattress has a design that actively minimises motion transfer, which means that you can sleep uninterrupted.


The mattress comes with a relatively high price tag, which can deter buyers from purchasing it.


Owing to the materials and design used in the mattress, it provides exceptional contouring and comfort for most sleepers, irrespective of their body type and sleeping positions. What’s more, the materials are CertiPUR-US, and GECA-certified, so you can rest assured about the safety of this option.

3. Hesperis Mattress

When it comes to flexibility, the Hesperis Mattress is probably the best option that is available today. This mattress is divided into 7 ergonomic sections with 4 different firmness levels so that you get the optimal level of support at each pressure point. Simply adjust the mattress according to your preferences, and you can sleep in any position without feeling uncomfortable.

Inside the mattress, there is a layer of gel-infused memory foam, which actively dissipates heat to give you a cool and dry sleeping experience. On top of that, the cover is made from 25% coconut fibres and temperature-forged bamboo textiles, which help to absorb sweat. Not only that, but it also prevents the growth of dust mites and bacteria so that you can sleep on a clean surface.


The edge support on this mattress is not up to par, which can affect its long-term usage.


All the materials used in this mattress are CertiPUR-US, and OEKO-Tex certified, so it can be considered to be safe for you and the environment. Furthermore, we found the 120-night trial to be quite convenient since it allows you to test the mattress extensively to be sure of your purchase.

4. Onebed Original Mattress

The Onebed Original Mattress is a highly versatile mattress that suits all types of sleepers regardless of their weight and preferred sleeping position. This is possible because of the innovative design that incorporates a latex layer alongside a viscoelastic memory foam layer. The natural latex and memory foam layers are adjustable, and they complement each other to provide optimal firmness and bounce to the mattress while minimising motion transfer.

These two layers make the mattress highly breathable as well. They work well with the dimpled polyester cover to dissipate excess heat and absorb sweat quickly. Speaking of the top cover, you’ll be glad to know that it is easily removable and machine washable. Also, the 17-cm thick polyurethane base layer deserves special mention since it provides exceptional edge support that prevents sagging.


The Onebed mattress is slightly firmer than other memory foam mattresses, which can make it a bit stiff for light sleepers.


Thanks to the hybrid mattress design and high-density base layer, the mattress is extremely durable, which can be further signified by its 15-year warranty. And despite having materials such as polyurethane, the mattress is CertiPUR-US and OEKO-Tex certified, which makes it entirely safe for use.

5. Ergoflex 5G Memory Foam Mattress

The Ergoflex 5G is another premium memory foam mattress option. This mattress includes 5 layers of memory foam to provide optimal support and comfort for all types of sleepers. The topmost layer consists of high-density viscoelastic memory foam that seamlessly adjusts to the body contours without sinking too deep. It also helps to minimise motion transfer so that you can sleep undisturbed.

There is another layer inside the mattress, known as the Ergoflex Cool-Sleep airflow layer, whose primary function is to enhance the airflow in the mattress. Combined with the highly breathable TENCEL outer cover, you get exceptional sweat absorption and temperature control. What’s more, the outer cover is naturally anti-allergenic, and it can be easily removed, and machine-washed, which makes it highly convenient to use.


This mattress only comes with a 30-day trial period, which is relatively low compared to the previous recommendations.


Considering the support and contouring provided by the Ergoflex memory foam mattress, it is a great choice for those who suffer from chronic pain and joint problems. And owing to its innovative design choice, you won’t need to worry about sagging issues, which means that you can use the mattress for a long time.

Frequently Asked Questions

That was our list of the 5 best memory foam mattresses. After going through it, have you decided on which one you want yet?

Of course, we understand if you are still in a fix about which option will be the best for you. Selecting a good memory foam mattress isn’t easy, and if our experience is to be believed, you might have quite a few questions at the back of your mind.

That is why in this section, we have answered some of the most common questions asked by consumers. So, if you want to clear away those lingering doubts, we suggest that you keep reading.

1. What Are Some Features To Look For In A Memory Foam Mattress?

If you are looking to purchase a good memory foam mattress, you need to check out some of its features before spending your hard-earned money on it. This will ensure that you get the most use out of the mattress.

These features are:

A. Firmness

One of the first things that you should check out in a memory foam mattress is its firmness level. Usually, the mattress firmness is measured on a scale that ranges from 0 to 10. A soft memory foam mattress will score lower on the scale, while a firmer mattress will have a higher score.

In most cases, memory foam mattresses come in a medium firmness level that is neither too soft nor too stiff.

However, if you are a heavy sleeper, such a firmness level will not be supportive enough for you. When you sleep on a medium mattress, it will tend to sink in, which can be quite uncomfortable. That is why some manufacturers use high-density memory foam, which has a slightly higher medium-firm rating. 

In our opinion, this is the best firmness level since it is suitable for both light and heavy sleepers. Aside from that, a medium-firm mattress is soft enough to hug your curves in any sleeping position. Also, such a mattress will not sag easily, thereby improving its durability. So, if you are looking for a versatile and durable memory foam mattress, you should try to get a medium-firm option.

B. Breathability

Breathability is another crucial factor that determines the utility of a memory foam mattress, especially for hot sleepers. When we say breathability, we are referring to two intrinsically linked features of the mattress, which are heat dissipation and sweat absorption.

If the mattress cannot eliminate the excess heat inside, it will automatically cause you to sweat a lot, which, in turn, will make it uncomfortable for you to sleep on. Thus, in order for a mattress to be comfortable, it needs to have good breathability. This can be achieved if the mattress layers are adequately ventilated to allow the passage of air through them. 

Alternatively, many manufacturers may use gel memory foam for this purpose since it can effectively absorb heat and sweat. Likewise, the outer cover of the mattress can be made porous to allow the excess heat to escape while simultaneously absorbing body sweat. So, unless you want to wake up all hot and sweaty in the middle of the night, you should definitely check out this feature before buying the mattress.

C. Materials Used

Believe it or not, most manufacturers use different other materials in addition to traditional memory foam to enhance the overall usefulness of the mattress. That is why it is important to check out the materials used in the mattress so that you will get an idea about what you’re exactly buying.

The composition of the memory foam itself might be different. Manufacturers may prefer using other natural materials instead of polyurethane, which is what most memory foam is usually made from. This is to ensure that the mattress is safe, not only for you but also for the environment. 

Aside from that, manufacturers may use other textiles and fabrics on the outer cover to improve breathability and make the mattress hypoallergenic. SImilarly, they may make a hybrid memory foam mattress which may include other layers in between the memory foam layers.

The most common materials used in this regard are pocket springs or natural latex since they are both readily available and enhance the overall structure of the memory foam mattress. If you want our opinion, we would highly recommend getting such mattresses since they provide greater utility and value for your money.

2. What Are The Different Types Of Memory Foam?

When looking to purchase a memory foam mattress, you should have an idea about the different types of memory foam available today so that you can make an informed decision. Broadly speaking, there are 3 distinct types of memory foam, with each of them having its own pros and cons.

These 3 types have been discussed below.

A. Traditional Memory Foam

This is the most basic variant of memory type that was developed. Since it was the first memory foam to enter the market, many consider it to be the original memory foam.

It is derived from polyurethane, which is a synthetic polymer known for its versatility and viscoelastic properties. As such, traditional mattresses made with this memory foam are relatively soft and are capable of conforming to the contours of your body seamlessly.

However, traditional memory foam comes with one major issue, which is its inability to dissipate heat properly. Because of that, the mattress may feel uncomfortably warm after a while.

B. Open-Cell Memory Foam

Open-cell memory foam was developed to address the heat dissipation issues observed in traditional memory foam. While it is derived from the same material as the traditional variant, its internal structure is noticeably different. This memory foam consists of numerous small pockets inside it to allow the passage of air and eliminate any excess heat. These pockets appear like miniature open cells, hence the name.

Besides improving ventilation, these pockets enhance the insulation of the mattress too, which makes it perfect for both temperature extremes - hot or cold. On the other hand, the presence of such empty spaces inside the mattress reduces its overall density and makes it a lot fluffier, which, in turn, reduces the firmness of the mattress.

If you are a light sleeper, you will not be affected by this aspect that much; if anything, it might be an advantage, given your lighter weight. But in the case of heavy sleepers, the reduction in firmness can be a serious issue, as the mattress will feel less supportive of their weight.

C. Gel Memory Foam

This is another variant of memory foam that uses viscous gel materials in its construction. The gel is pumped into the foam as microbeads during the manufacturing process. Other than that, the composition of the memory foam itself remains the same as the previous two types.

The gel material settles in between the foam to create small gel pockets, which are very similar to the air pockets observed in the open-cell variant. These gel pockets actively absorb the excess heat and dissipate it outside, thereby keeping the mattress cool.

In essence, gel-infused memory foam can be considered to be an upgraded form of open-cell memory foam since it possesses similar heat dissipation properties without compromising firmness. On the flip side, the price of a gel memory foam mattress is slightly higher than a traditional or open-cell memory foam mattress.

D. Plant-Based Memory Foam

As the name suggests, this is a type of memory foam that is derived entirely from plant materials instead of synthetic polymers like polyurethane. These polymers do not decompose as easily, which raises sustainability concerns about conventional memory foam. 

Thankfully, plant-based memory foam takes care of this issue since it is biodegradable and hence, more eco-friendly than other memory foam variants. However, plant-based memory foam mattresses are considerably more expensive than conventional memory foam mattresses, which can deter users from buying them.

3. Are Memory Foam Mattresses Good For People With Chronic Pain?

Considering the nature and firmness of a typical memory foam mattress, we’d say that it is a great choice for most people suffering from chronic pain. We say “most” because there are certain aspects that need to be kept in mind here. 

For starters, you’ll need to consider the type of pain you are experiencing. Usually, it is determined according to the part of the body that is affected, such as joints, lower back, neck, shoulders and so on. 

Memory foam is known to be highly conforming by nature, which means that it can hug the contours of different body parts easily. Because of that, you can get relief from all types of pain since the mattress will effectively relieve the pressure in the affected body part.

You will also need to consider the type of body you have because the responsiveness of memory foam varies between different body types. Generally, it is the most responsive for light to average sleepers since it can easily withstand the weight of such people. 

But for heavy sleepers, the medium firmness of the memory foam might feel too soft, and because of this, they will sink deeper into the mattress. That, in turn, will restrict the movement of the joints and pressure points, which can further aggravate their pain.

So, we suggest you go with a high-density memory foam mattress if you are a heavy sleeper, as it will have a firmer structure than regular memory foam mattresses. Or, you could opt for a hybrid memory foam mattress that includes innerspring coils or latex layers to improve firmness.

4. Are Memory Foam Mattresses Safe?

As we have mentioned before, memory foam is mostly made of a synthetic substance known as polyurethane. In that context, the conventional manufacturing processes for memory foam use other synthetic additives, which obviously raises concerns regarding the safety of such mattresses.

However, you will be relieved to know that due to strict governmental regulations, manufacturers these days are moving towards safer manufacturing practices that do not use such chemical additives. This can be demonstrated by the various safety certifications these mattresses come with.

They are opting for plant-based memory foam as well, which is a lot safer than polyurethane. So, not only are these mattresses safe for you, but they are also safe for the environment. 


That’s all we have to say about the best memory foam mattress in Australia. We hope that you have been able to come to a decision by now.

Before wrapping up, we would like to mention our personal favourites from the list. The Emma Comfort Mattress comes with well-rounded features at a reasonable price that makes it our top pick overall. 

But if you want a more premium-quality option, you could spare a few more bucks to get the Koala Mattress, which is our second favourite option. It provides superior comfort and support, which can make the investment worthwhile.
