Ergoflex 5G Mattress Review

Ergoflex may be one of the less well-known options in the crowded Australian online bed-in-a-box industry, but it is a high-quality memory foam mattress and is likely the finest we’ve tried. The company even goes on to say that their mattress is a comparable alternative to the three times more expensive Tempur Original ultimate mattress (in our tests, we found the claim to be reasonably accurate).

The entire idea of a memory foam mattress is that it closely conforms to body shapes for more comfort, which increases the likelihood that your spine will be properly supported in a healthy posture and decreases the likelihood that pressure spots will develop. All of this is beneficial, but the Ergoflex 5G mattress is best for those who desire a particular level of firmness and sensation.

Read our comprehensive review to determine if the Ergoflex mattress is the best fit for you.

Ergoflex 5G Mattress Review

Our Methodology

Mattresses are individualized items; what may be comfortable for one person may not be for another. We therefore base the review on the consensus of customers and industry professionals in addition to our objective tests and personal evaluation. This, in our opinion, is a more wholesome method of mattress evaluation.

Review Summary:

Unlike other businesses that frequently sell memory foam mixtures (usually low density), Ergoflex 5G is a TRUE memory foam mattress constructed from high-density foam. Additionally, the memory foam layer is 9 cm thick, approximately twice as thick as what most brands provide.

The mattress is slightly firmer than medium firm (7/10) in terms of firmness. The mattress softens to roughly 6.5 when you lie on it, though, as you gradually “melt” in the memory foam layer and feel a hug that conforms to your curves.

You sink into the mattress but not too deeply because of the typical memory foam gradual sink-in “hug” or quicksand effect of the mattress. Most sleepers should benefit from the sufficient pressure relief and support it provides, especially those seeking pain alleviation.

The mattress’ ability to regulate temperature is one feature that stands out. It sleeps relatively cooler than regular memory foam mattresses because it doesn’t trap heat as much. Additionally, the edge support is respectable and superior to most foam mattresses.

However, it might not be suitable for everyone.

Who may like the mattress?

  • Those who favor memory foam’s traditional contouring/hugging sensation.
  • Side, back, and stomach sleepers who are light to average.
  • Those seeking relief from back pain. The mattress provides outstanding pressure relief by following the contours of the body and encouraging proper spinal alignment.
  • Customers looking for a long-lasting mattress from a reputable manufacturer.
  • Those seeking a memory foam mattress that doesn’t get hot at night.
  • Those in a relationship who demand complete motion isolation.

Who may not like the mattress?

  • Those who don’t like memory foam’s “hugging” feeling.
  • people who weigh more than 110 kg.
  • Due to memory foam’s delayed rebound, combination sleepers may find it challenging to change positions.
  • People who cover their mattresses with electric blankets.

Tl;dr: The best memory foam mattress we’ve tried and evaluated is without a doubt the Ergoflex. The Ergoflex 5G is a bed that is supportive, firmer than normal, and provides good pressure distribution if memory foam is your thing or if you’re looking for a bed.

Particularly for those who have joint or back pain when sleeping, memory foam’s deep compression and pressure-relieving qualities make it the perfect choice.

Firmness & Feel

Firmness and feel are the two most important aspects to consider when purchasing a mattress. Let’s now examine the mattress’ firmness, feel, and how well it would support lighter, average-weight, and bigger people.

How firm is the Ergoflex mattress?

It’s difficult to describe how firm a bed is in general, but memory foam makes it a little trickier. As you lay on a memory foam mattress, body heat causes it to soften. As a result, the mattress may seem a little stiff at first before becoming softer and more comfortable.

The firmness of Ergoflex 5G is close to 7/10, which places it on the firmer end of the medium firmness spectrum. However, the mattress relaxes and feels close to 6.5, or roughly medium firmness, until the top memory foam layer heats up (takes a few seconds).

A quick note:

Being a subjective measurement, firmness differs from person to person depending on preferences, weight, and even body type. Therefore, a mattress that a bigger person would consider soft can seem stiff to a person of ordinary weight.

How was my sleep experience?

I’m an average-built person, standing at 5’10” and weighing 72 kg. Although I usually sleep on my side, I frequently switch to doing so.

Here’s what I make of the bed.

The mattress seems a little stiff at first, but as the memory foam layer begins to work, you begin to sink in and experience a sense of weightlessness. In any sleeping position, you receive exceptional support, pressure alleviation, and even weight distribution. Those who have neck or back problems should sleep comfortably on the bed in particular.

The mattress was most comfy for sleeping on your side. Deeply conforming to the neck and spine’s curves, the mattress relieves pressure points while maintaining the spine’s natural alignment.

I had an excellent blend of support and comfort while sleeping on my back and stomach.

I also observed that I was sleeping well on this bed rather than shifting positions frequently as I typically do. This is mainly because the memory foam layer has a hugging, enveloping sensation that somewhat limits movement. Although you don’t feel trapped or like you’re sinking in too much, it is still rather constrictive, which active or combo sleepers might not like.

Last but not least, the bed was quite temperature neutral, like Koala or Ecosa, and I didn’t feel hot on it.

I believe the key factor in determining whether the mattress is good for you is whether you enjoy the way memory foam feels (according to statistics, 95% of people do).

Note: Unlike other memory foam beds, this mattress is not compatible with electric blankets. The mattress does, however, sleep a little bit warmer than standard mattresses, necessitating the use of a heated blanket.

What does the mattress feel like?

Ergoflex 5G feels like traditional memory foam. You experience memory foam’s typical sluggish response, low bounce, deep contouring, and hugging sensation. Numerous reviewers compare the experience to “sleeping on a cloud” and that it is practically weightless.

You typically stay on the bed for a short while before gradually sinking into the memory foam layer when you sleep on it. Switching positions can be a little challenging because you tend to sleep more “in” the mattress than on top of it. The mattress relieves pressure points and encourages appropriate spine alignment because of the foam’s strong embrace and support.

Unlike innerspring or hybrid mattresses, which primarily provide support where the springs are, you get constant and even support throughout.

For lightweight (under 58 kg) & average-weight sleepers (58 to 104 kg)

Light to average weight sleepers should find the mattress pleasant in most sleeping positions because it is highly adaptable. This is mostly because to the comfort layer of 9 cm thick, more substantial memory foam.

According to the weight and pressure of the person, the layer sinks and curves equally. Smaller people would therefore sink in slightly while people of normal weight would sink in slightly more, but both would feel equivalent firmness. In contrast, lighter people typically find innerspring or hybrid mattresses to be stiff because they are unable to apply enough pressure to fully engage the comfort layer.

For heavy-weight sleepers — Over 105 kg

The mattress is pretty firm, thus heavier people may not feel comfortable on it. This is due to the fact that most of these sleepers would reach the transition layer, which is more firmer, after reaching the comfort layer’s maximum. The metal spring coils in an innerspring or hybrid mattress often provide stronger support for heavier people.


A 9-inch thick all-foam bed called the Ergoflex 5G has three separate layers wrapped in Tencel fabric: a visco-elastic memory foam comfort layer measuring 9 cm, a corrugated layer measuring 5 cm, and a 9 cm high-resilience foam support core measuring 9 cm.

Let’s examine each layer in more detail now to determine how they affect the mattress’ overall functionality.

Ergoflex 5G Construction

TENCEL Removable Outer Cover: Hypoallergenic, washable, and breathable. TENCEL is an organic fabric that wicks away moisture and has built-in antibacterial properties. It doesn’t clump or bunch up and is quite elastic. Additionally, the mesh design enhances the mattress’ ability to breathe.

Ergoflex 5G Outer Cover

Inner foam layers are protected by a micro-fine protective layer made of poly fabric.

The mattress’s main selling point is its high-density, 9 cm thick top layer of visco-elastic memory foam.

This temperature-sensitive layer provides deep body contouring and high-quality pressure relief by gently responding to pressure, closely conforming to the shape of the body, and supporting the body. In addition, the PU foam’s open-cell structure promotes airflow movement between layers, keeping everything cool and permeable.

According to the manufacturer, the memory foam utilized is nearly twice as dense as brands in the same price range. Higher density foam typically provides better pressure relief, better support, and closer body contouring while being more long-lasting.

Ergoflex refers to the patented transition layer (diameter: 5 cm) as the “Cool-Sleep airflow system”. The corrugated pattern of the foam promotes ventilation and aids with temperature regulation, which is especially helpful on hot, muggy Australian nights. Compared to the top layer, this layer is a little firmer.

High-Resilience Base Layer [9cm] – Impact-resistant Dense PU Layer that Provides Durable Support and Gives the Bed Its Shape.

The foams and fabrics used in the mattress are OKEO-TEX® 100 and CertiPur-US certified, indicating that they were created without the use of hazardous chemicals in a non-volatile environment.

It’s vital to remember that Ergoflex no longer refers to the foam density used, much like Tempur does. The 75 kg/m3 foam utilized in the prior version, Ergoflex 3G, serves as a point of comparison.

For even wear, the manufacturer also advises flipping the mattress from top to bottom every three months.

Mattress Performance

Sleep temperature

Memory foam is well known for retaining body heat and making people feel toasty while they sleep. However, Ergoflex’s distinctive design and material selection make it very temperature-neutral. The mattress shouldn’t be too warm for most typical individuals, however hot sleepers may have trouble.

You might be wondering how Ergoflex manages to do this given that it is a memory foam mattress. First off, Ergoflex employs open-cell memory foam instead of closed-cell foam since it is more breathable. Additionally, the corrugated foam transitory layer and mesh Tencel cover encourage airflow, keeping sleepers from being overheated.

As a result, if you tend to sleep too warmly at night, you might want to consider an innerspring mattress or an active cooling mattress with gel infusion or water cooling technology.

Motion isolation for couples

It certainly isn’t surprising that the Ergoflex mattress performs exceptionally well at motion isolation. When it comes to separating and limiting the transfer of motion, memory foam is the best material available. This indicates that because there is little motion transfer across the surface, sleepers are unlikely to be awakened by their partner’s activity.

Couples and light sleepers will benefit the most from the Ergoflex mattress’ primary strength, which is motion isolation.

Edge support

When compared to mattresses made entirely of foam, the Ergoflex 5G mattress provides a decent amount of edge support. Although it isn’t as strong as the support found in innerspring mattresses, the support is nevertheless largely stable. Unless you’re a hefty person (above 100 kg), you won’t feel like you’ll roll off the bed while sleeping or sitting near the edge.

The responsive and supportive base layer is the secret to the Ergoflex 5g mattress’ superior edge support. Under pressure, the top layer of memory foam easily contracts, but the lower two layers offer enough resistance to prevent excessive sinkage at the borders.

Sex comfort

A responsive and bouncy mattress would be ideal for sex mattresses because it makes it simple to adjust positions. Ergoflex has a top layer of memory foam that is comparatively thicker but delivers little to no bounce, making it less suited for sex. Couples may feel constrained as one prefers to sink into the mattress.

The mattress has good traction in addition to deep sinkage, which may make it more comfortable for couples who don’t frequently switch positions during the night. Additionally, because it is made entirely of foam, it is completely silent and unobtrusive during sex.


Ergoflex has been in operation longer than its warranty duration (10 years), in contrast to the majority of bed-in-a-box brands. In fact, during our investigation we found a number of customer evaluations from people who had been using the mattress for over ten years and had not seen any sagging. This is consistent with what we have also seen.

The durability and endurance of the mattress are often determined by the density of the foam. The Ergoflex mattress has a projected lifespan of 8 to 10 years, which is outstanding for all-foam beds given that it is comprised of high-density foam.


Customers should anticipate a minimal amount of off-gassing from the Ergoflex 5G mattress right out of the box, similar to that of all-foam beds like Koala or Ecosa. The majority of consumers said the scent goes away in a day or two.

During the first few days, all-foam beds have a tendency to release VOCs, giving them the recognizable “new mattress odor.” Unless a person has a very acute sense of smell, these VOCs shouldn’t disturb most people and aren’t thought to be dangerous.

Company Policies

Examining the small print is as crucial when purchasing a mattress. The warranty, sleep trial, and return policies of Ergoflex have been described.

Ergoflex 5G package

Delivery (S&H)

The vacuum-sealed Ergoflex 5G mattress is delivered in a small package. The mattress is notably heavier than the majority of all-foam beds, so it’s a good idea to ask for assistance when setting it up. It will take around 4 hours for it to unfold and take shape once it is taken out of the package.

The cost of shipping varies by location. Ergoflex provides 24-hour delivery to urban areas for a fee of $24.99 ($89.99 for Saturday or after-hours delivery). Delivery to suburbs is $69.99, while delivery to rural areas costs $299.99 and takes four to ten days.

These days, free shipping for mattresses is more commonplace, which is partially attributable to the businesses’ excellent profit margins. They are therefore able to pay the delivery price. However, we don’t think the delivery price is a major drawback given the value the Ergoflex 5G mattress delivers and how substantial it is in comparison to other competing brands.

Sleep trial

Even though Ergoflex invented the risk-free mattress trial, it doesn’t currently have the most liberal trial period on the market. The Ergoflex 5G memory foam mattress is available for 30 nights after purchase, but you can only return it after night 21 (because to the adjustment phase most people experience when switching beds).

This might come across as a little unsettling, but reports suggest that Ergoflex would be pleased to extend the trial time if requested. Even while it still doesn’t compare to programs like Ecosa’s 100-night trial or Koala’s 120-night sleep trial, 30 nights (with the possibility of an extension) are still preferable than nothing.

Return policy

Within a 50 km radius of major cities (Adelaide, Brisbane, Melbourne, Perth, and Sydney), returning a mattress is free. A return fee of between $100 and $250 is payable for regional areas.

Not just Ergoflex, but the majority of bed-in-a-box companies charge a distant site return fee.

Per household, only one return request is valid. Ergoflex must receive the return requests within 30 days of the mattress’ delivery.


The mattresses must be undamaged and clean when they are returned. Before starting the return procedure, Ergoflex can ask for a photo of the mattress.


Ergoflex takes pride in holding the exclusive title of being the only Australian bed-in-a-box manufacturer whose 10-year warranty has passed the real-world test. Ergoflex, unlike most new-age internet mattress businesses, was introduced in Australia in 2010 and has been in operation for more than ten years.

Any apparent sags of more than 1 inch (2.5 cm) or any material or workmanship flaws are covered by the warranty. Additionally, a 2-year warranty against manufacturing or material flaws is provided for the detachable cover. At its option, Ergoflex will either fix or replace the mattress; a shipping and inspection fee might be necessary.


To claim the warranty, the mattress needs to be registered with Ergoflex within 30 days.

Buyer Feedback & Complaints

In an effort to determine how actual Australian customers felt about the Ergoflex 5G mattress, we evaluated over 250 real customer reviews. What were they feeling? It seems to be rather good! The general consensus is favorable.

  • When consumers were surveyed, 94% said the mattress didn’t make them uncomfortable.
  • A staggering 98% of consumers said that there was virtually no sagging in the mattress during their use.
  • 84% of consumers who purchased cool products said their mattresses did not retain any heat.
  • Finally, a startling 83% of customers claimed to have become accustomed to the mattress within a few days, with another 10% reporting doing so within the subsequent weeks.

Customers laud the bed’s supportive and pain-relieving properties, with one saying they “bought three, one for each room.” They go on to explain, “They are especially supportive for back, hip, and neck problems.” An additional Australian consumer who suffers from a poor back concurs: “I find it very difficult to find a decent mattress. I’ve enjoyed the nicest sleep in the past 25 years because to this memory foam mattress. It took me just two nights to realize this. Simply brilliant.

Customer reviews also give Ergoflex’s customer service some spotlight time. After experiencing delivery problems, one client commended Ergoflex for keeping them informed and stated that the business “always answered emails and phone calls quickly.”

Although most customers don’t share this issue, one customer who is happy with the bed advises against sitting on the edge in the same place because it “may affect firmness”.

Summing It Up

The Ergoflex 5G is a high-quality mattress that is not only long-lasting but also fairly inexpensive.

Ergoflex is undoubtedly one of my top selections if you’re searching for a memory foam mattress, and I do recommend it.
