Ergoflex - best firm foam mattress

The Ergoflex memory foam mattress is the original mattress in a box company in Australia. By creating their own 5g proprietary visco-elastic material, they don't sacrifice quality for cost savings. 

It’s OKEO-TEX® 100 certified so it’s ideal for asthma & allergy sufferers. It has excellent breathability because of the egg crate design. We are not fans of this type of design, as it means less foam for support, but because the top layer is 9cm thick, you won't notice.

Why Should You Choose It?

a) Stood the test of time

It’s one of the only mattresses to have been around longer than its warranty. From everyone we have spoken to, this mattress keeps its shape even after 6+ years. The first edition was released in 2006.

a) Reviews

Ergoflex has one of the highest reviews out of all the foam mattresses in Australia, with most of them being five stars (over 3,000). However, it doesn’t quite top Emma. 

a) Back pain

The hospital-grade materials provide orthopaedic pressure relief, making the mattress excellent for back pain. Even though it provides ample support you'll find it to be a comfortable soft mattress.


  • Orthopaedic memory foam
  • Also available in the UK
  • 10 year guarantee


  • You only get a 30 night trial (lowest out of all the mattress in a box companies)

Buyers guide

How we made our choices

We looked through the Australian mattress market and separated all the spring mattresses. Then we went through customer reviews, trial length, features, pricing, and more. We also looked through our comprehensive mattress reviews to ensure our ratings are from multiple sources and unbiased.

We split up our choices into categories because not all memory foam mattresses are the same. Some are firmer or softer, and some have multiple different layers.

Pure vs Hybrid Memory Foam Mattress

Many memory foam mattresses do not contain 100% memory foam (Visco elastic foam). They are generally 3 layers, the:

  • Top: comfort layer
  • Middle: transition layer
  • Bottom: durable layer

Spring mattresses are not just hybrid mattresses, hybrids have a similar comfort layer of memory foam, then another type of foam, and springs. There's nothing wrong with this. The reason for this is threefold: 

  • To add bounce and durability.
  • Improve breathability.
  • Make it suitable for a range of sleepers. 

Traditional memory foam mattresses have that material as one of their first or second layers, providing the mattress with its body contouring properties. The base layer is usually made of high-density foam for support, while other layers vary according to the manufacturer, with latex and gel foam being the most popular. 

The reason to get a pure foam mattress are: 

  • It offers excellent pressure relief (great for back or other pains)
  • Minimal partner disturbance (your partner's movement won't wake you up)
  • Hypoallergenic: Great for those with allergies (anti: dust mite, dust, mould and other allergens)

What are the Different Types of Memory Foam?

There are three types of memory foam: traditional, open cell, and gel-infused. There are advantages and disadvantages to each of these, so let's take a quick look at them.


By molding to your body, traditional memory foam provides a comfortable sleep experience. The biggest complaint is that it retains body heat, making it uncomfortable to sleep in high temperatures. However, most companies on our list combat this. Below are two reasons:

Open Cell

Open cell memory foam differs from traditional memory foam in its internal structure. Open cell memory foam allows air to flow more freely, which helps it transfer heat away from your body while you sleep.


A gel memory foam, or gel-infused memory foam, is a type of memory foam that has been filled with gel, and there are two types. The first type simply absorbs heat. Think of it as an ice pack. The second type is actually a phase-changing material. This stuff works by absorbing and releasing heat while you sleep.

Side note: Gel-infused memory foams can increase density, but they can also cause the mattress to degrade more quickly.

What to look for

As pointed out earlier, memory foams are not all created equal, and their qualities may range from density to temperature responsiveness to hardness and durability.


Generally, the denser the memory foam, the more supportive and durable it is. Lower quality memory foam weighs between 2 to 3 pounds per cubic foot, while premium memory foam weighs approximately 4 to 5 pounds per cubic foot.


This is a subjective matter. Most mattresses are designed to be medium-firm, which is best for most people in terms of support and comfort. Some people prefer a softer or firmer mattress since they feel it will be more comfortable, but a medium-firm mattress is generally the best option.

On the other hand, if you are on the heavier side, you might want a hybrid mattress for more support, and most bed in a box brands offer a trial period, so you can return it if it is too firm or too soft for you.


It is possible for cheap mattresses, or mattresses manufactured in countries like China, to contain toxins and other potentially harmful chemicals. To ensure the foam is free of hazardous substances, look for certifications like:

  • Centripur-US

Or similar standards.

Sleep trial & warranty

A mattress is a big investment since you'll be using it for a long time (typically 7 to 10 years). In this case, the long warranty and sleep trial can come in handy, as you don't want to compromise on quality.

Look for mattresses that come with at least 90 days of sleep trial. This will give you plenty of time to sleep on the mattress, to find out if it's to your liking, if not you have the option to return it. Most brands it's free but some companies will ask you to ship the mattress at your own cost, depending on where you live.

Look for a warranty of at least 10 years since that's the typical lifespan of a bed. It should cover manufacturing defects and sagging beyond the warranty period. The average company provides coverage up to 3/4 inches of sagging.

Benefits of memory foam

We have listed many benefits in this article. Here's a recap:

Pressure relief: Memory foam alleviates pressure points by contouring your hips and shoulders instead of resisting them like coils usually do. When you awaken, a memory foam will comfortably hug even the smallest sleeper and ensure that there will be no sore points.

Spinal support. If you sleep on your side, your spine should be parallel to the ground, and if you sleep on your back, your spine should maintain its natural curves in the cervical, thoracic, and lumbar regions. With its ability to cradle protruding parts of the body, memory foam can ensure neutral spinal alignment in any position and prevent back pain.

Motion absorption. Memory foam's viscosity and closed-cell structure allow it to 'lock' the movement within the cell and prevent it from spreading across the mattress. If your partner is a restless sleeper, you will finally be able to snooze without any interruption.

Hypoallergenic properties. Nowadays, every mattress company produces memory foam using its own recipe. In the end, however, the final result is a stable compound that doesn't contain harsh chemicals that may be harmful to your health, and is resistant to mould, dust mites, and allergens.


Why a memory foam mattress?

Memory foam conforms to your body closer than other mattress types—the hugging effect results in better spinal alignment and pressure relief when you sleep. Memory foam is excellent for minimal partner disturbance because the motion transfer is isolated to the point of pressure and gives little to no noise.

These qualities make memory foam superb for Aussies who are couples, especially if you wake up quickly due to noise or motion.

What Is a Boxed Mattress?

A mattress in a box is a new process when constructing mattresses, they can have a memory foam layer, latex layer, gel foam, and a large variety of different mattress materials. Then they are vacuum packed and sent to you.

‍Sleeping positions

We have covered a few different sleep positions below.

  • Back sleepers. If you sleep on your back, you create ideal conditions for maintaining a neutral spine. For back sleepers, the medium or medium-firm, comfort level is typically the best choice. With foam you'll receive a moderate hug in order to cradle your hips and buttocks to prevent an unwanted curve in your spine.
  • Side sleepers. If you sleep on your side, you need a mattress that can hug their hips and shoulders while maintaining a neutral spine. A medium-firm bed is ideal here, so you can alternate between side and back sleeping. This is because memory foam is responsive and moulds to the pressure and heat of your body.
  • Stomach sleepers. If you prefer to sleep on your belly, pick a mattress that has a firmer feel or provides more lumbar support. Sleeping on your stomach puts a lot of pressure on your lower back, so be careful not to sink too deeply. This position should be avoided as it will cause back pain. 
  • Combination sleepers. A combination sleeper changes positions frequently during the night. This makes choosing the appropriate firmness level a bit challenging, but a medium or medium-firm mattress is ideal, that's why most mattresses are made to fall into this category (unless ordered specially to be firm or soft).

In addition, your weight plays a part: the higher the BMI, the firmer the mattress you need. To compensate for the large weight and maintain natural spine curves. The best way to combat this is to get a hybrid mattress. 

Additionally, petite individuals (less than 60 kg) might want to choose something softer, because their weight might not be enough to compress the comfort layers, causing a firmer feel and insufficient pressure relief.

Can you flip memory foam mattresses?

Memory foam mattresses aren't meant to be flipped (unless otherwise stated). This is because they tend to have multiple layers:

  • A top comfort layer that contours to your body.
  • A middle breathable foam layer to disperse body heat.
  • Then a durable firmer base.

This varies depending on the mattress brands design. We do however, recommend that you rotate the mattress every few months to stop a permanent you sized shape in the mattress.

How long do memory foam mattresses last?

Memory foam mattresses last between 7-10 years. Most of the mattresses on the list have a warranty of upto 10 years, or over.

You'll find traditional innerspring mattresses to last around the same time. However, you can get a memory foam bed with springs which are hybrid mattresses. These are the best for both worlds and tend to have a longer lifespan.

Do memory foam mattresses sag?

All foam mattresses sag given enough time. However, if it's a new mattress or it sags within the first few years, that's not ideal and can be down to the mattress manufacturers fault. If this happens don't worry the warranty generally covers it, the Delta Sleep mattress has a 10 year 'sag free' guarantee.

Do you sink into a memory foam mattress

The best foam mattresses to hug and contour to your body. This is normal and what makes this type of mattress so go for pressure relief. Some people think this makes them soft mattresses, however, they are genery medium firm but let you sink in to align your hips, spine, and shoulders.

Do they sleep hot?

Memory foam usually isn't the best for hot sleepers because they retain body heat. However, most of the mattresses on the list sleep cooler because they have gel memory foam that doesn't trap heat.

Memory foam mattress cost

You'll find most foam mattresses to be affordable compared to traditional mattresses, they are also cheaper than hybrid mattresses because they don't contain springs.

Roughly, you can pick up a queen size memory foam mattress for $600, but not all memory foams are created equal, look at other mattress features, not just price.

What are the problems with memory foam mattresses?

Some of the disadvantages often associated with memory foam mattresses include;

  • Memory foam sleeps hot.
  • Memory foam has a strange smell.
  • Memory foam is too soft.

We covered the why they sleep hot, so lets cover the other two. The strange smell usually happens straight away after opening the mattress and is called off-gassing. It's because the mattress has been packed vacuumed packed in plastic for a long period of time.

Luckily, it goes away after a few hours. Pro tip: Open a window and leave the mattress to inflate for a few hours.  

Many people believe that the memory foam firmness is to soft. That's because of the pressure relief, however, you get plenty of support and most foam mattresses are medium firm.

Verdict on the best foam mattress au
