Ergoflex 5G Mattress Review Summary:

Ergoflex 5G Mattress Review.

Ergoflex 5G is the pure memory foam mattress in the truest sense of the word. Unlike many manufacturers that sell a blend of memory foam with the memory foam actually being in low density, Ergoflex uses a thick 9cm layer of memory foam. This is almost 2x the density of memory foam other brands offer.

The firmness of the Ergoflex 5G mattress is medium-firm but geared towards the firmer side of it, which is why it’s a 7 on a firmness scale of 10. Nevertheless, you will still feel like the mattress slowly melting under you as you lay on it. It hugs your body by conforming to it, going to 6.5 from 7.

You can say that it has a slow sink-in feel that’s native to memory foams – you’ll feel like sinking in but not too deep. The best parts of the Ergoflex 5G memory foam mattress include support and pressure relief, which most sleepers will find useful, especially for reducing body pains.

One feature that makes Ergoflex stand out the most is temperature regulation! Unlike many memory foam mattresses, it doesn’t trap excessive heat, so you sleep relatively cooler. It also offers decent edge support than most typical foam mattresses.

Who should Try Ergoflex 5G Mattress?

  • People who are light or average back, stomach, and side sleepers
  • Those looking for the classic hugging/contouring memory foam feel
  • Users searching for a sturdy mattress from a well-reputed brand
  • Those who have back pain issues and looking for a mattress that has excellent pressure relief properties and conforms to the body’s natural contour for spinal alignment
  • Couples who need a higher motion isolation
  • Those who need a memory foam mattress but with minimal heat retention

Who Should Look the Other Way?

  • People who do not like the hugging feel that memory foam offers
  • Couples with over 110kg weight each
  • Electric blanket users
  • People who change positions throughout the night because of the slow rebound of the mattress may take a little time to adjust to their new sleep position

There’s no doubt the Ergoflex 5G mattress is one of the best memory foam beds we’ve reviewed on this website. If you like nodding off on a memory foam mattress or if you’re looking for a bed that offers support with more than average firmness and incredible pressure distribution, then Ergoflex is worth looking into.

The pressure-relieving and deep compression properties of ErgoFlex 5G make it perfect for people with back or joint pain.

ErgoFlex Mattress – Firmness & Feel:

Ergoflex 5G Mattress Review.

When you’re purchasing a mattress, how it feels when you lay on it, and its firmness level are the key factors to consider. Let’s have a detailed look at factors like how firm it is, how it feels, and how it will accommodate people with different weight categories. That said, let’s get right into it:


It’s always a little complicated to describe the firmness of a bed and even trickier when discussing memory foam. This is because a memory foam mattress gets softer with body heat, so you may feel it a little firmer at first, but it gradually gets more comfortable.

In terms of ratings, we’d say Ergoflex has 7 out of 10 points on the firmness scale, which means medium firm but geared towards the firmer side. Nevertheless, as mentioned above, once the top layer of memory foam starts warming up to your body heat, it’ll soften and feel like 6.5 – medium.

Note: Although there are metrics like ratings in place to judge the firmness of a mattress, these will only give you a general idea of things. The support you receive from the mattress will greatly depend on the type of body you have, your height, weight, and sleep preference. So a lightweight person may find a mattress to be too firm while it may be soft for someone with heavier weight.

The mattress offers the classic feel of memory foam, which means you’ll get that slow, deep contouring and hugging feel with low bounce. Many users of the mattresses have also stated in their reviews that it feels like they’re sleeping on a cloud – feels weightless.

After laying down on the mattress, you’ll stay on top of it for a few seconds and then gradually sink into the top memory foam layer as it starts warming up. It’s like sleeping on a mattress than sleeping on it. Keep in mind. However, this also makes it a little difficult to switch positions during sleep. Still, this sinking feel provides support and hugs with your body, relieving pressure points from the body and aligning your spine.

Response to Different Weights:

Lightweight – under 60kg and 60-104kg:

People with lightweight will find the mattress to be very accommodating for most sleeping positions. This is because of the denser and thicker memory foam comfort layer of 9cm.

The foam contours and sinks evenly to the weight of the individual and the pressure it exerts. So people with petite bodies will sink less than those with average (58-104kg) weight sleepers. Still, both of these weight classes should feel a similar level of firmness.

Heavyweight – 105+ kg:

People with more than 105kg weight will find the mattress to be quite firm, which is why they may not properly enjoy sleeping on it. The reason is simple; their weight will put more pressure on the foam, pushing it to the transition layer that has more firmness.

Generally, people with heavier weight will find the hybrid or innerspring mattresses more comfortable as the spring coil base offers better body support.

Construction of Ergoflex:

The total thickness of the mattress with all three layers combined is 9 inches. it features three different foam layers including:

  • Visco-elastic comfort memory foam layer – 9cm
  • Corrugated layer for temperature elevation – 5cm
  • Support core high resilience foam – 9cm

All the layers are encased together in a breathable Tencel cover. Let’s break down the features of these layers below.

  • Memory Foam Layer: This 9 cm Visco-ealstic layer of memory foam is relatively thick (9cm), which is also its main highlighting feature. The layer is sensitive to temperature s it slowly starts to soften as the heat transfers from your body and into the foam. This ensures the mattress contours and hugs your body, relieve pressure and align the spine.
  • Transition Layer: This 5cm layer is a patented product by Ergoflex that they call ‘Cool-Sleep airflow system”. It has a corrugated design that allows for the air to move freely and regulate temperature. This feature is especially useful on hot and humid Aussie nights in the summer season. Keep in mind; this layer has more firmness than the top memory foam layer.
  • Base Layer: The 9cm high resilience layer at the end is a dense, impact-resistant polyurethane layer that forms the shape of the bed, reinforces the overall body support and increases the mattress’s durability.
  • Protective Layer: All three foam layers are encased in a poly fabric sock that protects them from environmental factors. It is non-removable.
  • Tencel Cover: Lastly, the mattress is further protected in a breathable, hypoallergenic TENCEL fabric cover. It’s stretchy, wicks away moisture and doesn’t bunch up. Furthermore, the cover can easily be washed, making it incredibly functional and easy to care for.

The Ergoflex 5G mattress leverages Oeko-Tex 100, and CertiPur-Us certified materials, so it’s clear they’re produced in no or very low volatile environments, almost free from harmful and toxic chemicals.

Ergoflex 5G Mattress – How Does it Perform in Different Areas?

Temperature Regulation:

Ergoflex 5G Mattress Review.

Memory foam is known for trapping heat emitting from the body, increasing the sleeper’s temperature and making them feel hot. However, the memory foam used in Ergoflex is an exception. It leverages unique materials and an airflow-friendly design that keep the temperature from rising. Most people will not feel the bed getting hot under them, but those who naturally sleep hot may struggle a little.

Now the question is, how does Ergoflex do this, even though it’s a memory foam mattress? That’s because it boasts an open-cell design that’s more breathable than its closed-cell counterpart. Moreover, it has a transient corrugated layer beneath that further promotes airflow. Lastly, the breathable Tencel cover with mesh design lets the air escape easily and take the body heat with it.

That said, if you’re a natural hot sleeper, you may find a gel-memory foam or innerspring mattress working better for you.

Motion Isolation:

Ergoflex 5G mattress offers excellent motion isolation, and that’s expected because of a 9cm thick memory foam that’s far superior at dampening vibrations arising from movements than any other material.

The memory foam localises the transfer of motion, keeping it from reaching the other end of the bed. There’s not a shred of doubt that motion isolation is the key strength of this mattress, and couples would definitely appreciate this.

Edge Support:

The edge support is fairly good, especially when you compare it with other foam mattresses. Even though it cannot compete with the innerspring mattress in the edge support, it is still reasonable. You will not feel like falling off the bed during sleep.

The key to this above-average support on the edges is the combo of supportive base and transient layer that are firmer than the memory foam. So when you sit or lie on the memory foam layer, it sinks in a little, but the other two layers beneath add resistance to that sinkage, ensuring the perimeter of the bed doesn’t sink too much with you.


Ergoflex 5G Mattress Review.

Ergoflex has been in the mattress industry for more than a decade, so the 10-year warranty it offers is less than the company’s age. This means there are many customers who’ve already used their mattress for 10 or more years.

And after thorough research, we came across people who reported no sagging on the mattress during their 10 years of use.


You can expect some degree of off-gassing as soon as the mattress is out of the box – it’s similar to other all-foam mattresses like Ecosa or Koala. According to most users, the gas goes away in 1-2 days.

All-foam mattresses typically emit VOCs for the initial few days, but they aren’t toxic and should not be a problem unless you’re highly sensitive to the smell.

Logistics & Warranty:


The mattress is shipped, vacuumed and sealed inside a box. The shipping cost and duration depends on your location. For metro areas, the cost is $24.99 and takes 24 hours for delivery. For suburbs, you can expect to pay $69.99, while remote locations cost $299.99 and take 4-10 days for delivery.

Keep in mind that it is a heavier mattress than most of its competitors, so it’s a nice idea to have an extra pair of hands to lift and move it around the house. Now we understand that most brands offer free delivery, while Ergoflex charges money for it.

However, those brands also have higher costs to value ratio because they absorb the delivery fee in that cost – no business ever makes money by shrinking their profits. So considering this, it should not be a problem paying for delivery.

Trial & Warranty:

Ergoflex 5G Mattress Review.

Although they have a risk-free trial, they are not very generous with it. Many companies offer 100 to 120 nights of sleep trial, but Ergoflex only offers a 30-night trial, and you can only return the mattress after testing it for 21 nights.

However, their warranty period is good enough as you get protection for 10 years against manufacturing and material defects and sags that are over 2.5cm.

Moreover, the removable Tencel cover also comes with a 2-year warranty against material or manufacturing defects. Depending on the situation, the company will either replace the mattress or repair it.


If during your 30-day trial you don’t find the mattress working for your sleep preferences, you can ship it back to their warehouse. The return is free if you’re within a 50km radius of metro areas like Brisbane, Sydney, Adelaide, Perth and Melbourne.

If you’re in regional areas, you may have to pay a $100 to $250 return fee. All mattress-in-a-box companies typically charge this remote location return fee, so it’s nothing new with Ergoflex.

Feedback From Users:

We went through hundreds of reviews from Ergoflex 5G users and noted down the feedback that was common among the reviews. The result was that most users felt pretty good using the mattress. there are a few things commonly found in the testimonials:

  • Over 90% of users found the mattress to be very comfortable
  • Over 95% of users reported no sagging at all
  • Over 80% of users experienced no heating issues
  • Lastly, more than 8% of users reported getting used to the mattress in just a few days.

Customers talked good things about the mattresses’ support and pain-relieving capabilities and how thoughtful and well-executed its design is.

Over to You:

There’s no doubt that Ergoflex offers a high value for the money, and almost everyone who bought this mattress is happy with how it’s performing for them. 

So if you’re looking for a memory foam mattress that offers all the benefits of memory foam without retaining heat, we’d definitely recommend Ergoflex.
