We'll answer these questions as we assess their layers and maintenance requirements.


The Ergoflex 5G mattress features the following five unique-designed layers: 

  • TENCEL® Top Cover: Removable, washable and with a mesh design that makes it highly breathable, the Ergoflex 5G's TENCEL Cover strikes all the right notes of an incredible mattress cover

3. Comfort, Firmness and Durability

Here, we'll help you decide the most comfortable option between the Ergoflex 5G and the Koala mattress. We'll also take a close look at how durable both options are. 


Ergoflex has a firmness rating of 7/10, making it medium-firm. This rating suggests that the Ergoflex 5G Memory Foam does quite well on the comfort front. 

However, some sleepers may still find that this doesn't cater to their needs, as they'd prefer something more or less firmer. Regardless, it's still a terrific mattress. 


You have two firmnesses options to select from, a medium firm being 7.5/10 and a firm-firmness of 9.5/10. This is great for individuals who would like the option of trying different firmnesses.


Durability is top-notch with Ergoflex, thanks to the 9cm high resilience foam base providing robust support for the whole mattress. There are also tons of customer reviews attesting to its longevity. 

On the other hand, Koala also boasts durability and it’s proven to provide a quite supportive sleep.

How do you sleep? On your sides or back? Perhaps, a combination of all sleeping styles depending on where tossing and turning leaves you? 

Which mattress is perfect for you based on your sleeping position? 


Generally, medium-firm mattresses are suitable for all types of sleepers. Thus, the Ergoflex memory foam should be a perfect match for you regardless of your preferred sleeping position. 

And it gets even better.

Individuals with back and joint pains will find the pressure-relieving support of this mattress soothing to their aches. Even medical specialists recommend it. 


The Koala Mattress is suitable for all sleep positions, with its special supportive upper zones providing the right balance of support and comfort.

Of course, both mattresses cater to a wide range of sleepers. However, the medical benefits of Ergoflex give it a significant edge.

Plus, all its layers work together to provide adequate support and comfort for users weighing more than average.

5. Night Trial, Returns and Warranty

This section of our comparison pits both manufacturers against each other on warranties, night trials, and returns. 

Ergoflex Vs Koala

Ergoflex offers you a 30-night trial period after purchase to decide if the 5G Memory Foam is ideal for you. 

Of course, this timeframe is significantly shorter than what you'll find elsewhere, but the company does leave room to extend the night trial if you request it. 

If you find that the mattress doesn't meet your nighttime needs, you can return it anytime within 30 days or during the extended period for a full refund. However, the pickup may take 7-14 business days. 

Also, Ergoflex won't charge you a return fee if you stay in a metro area. Customers outside the metropolitan areas may pay a fee of around $150 to $250, depending on their location. 

That's not all:

The mattress also comes with a 10-year warranty that covers all artistry and material defects. 

On the other hand, Koala has a more lengthy trial period, as you get 120 days to try out your mattress and decide if it meets your nighttime needs. 

If you don't like what you paid for, the company will pick it up for free within four hours if you stay in the metro areas. You also get a complete refund. 

For customers outside metro regions, the pickup may take longer and attract a charge. The Koala mattress also comes covered with a 10-year warranty. 

Feature Winner

The Koala Mattress

We'll give it to the Koala this time. Its night-trial period is significantly longer, and pickup time within the metro areas is much shorter.

6. Environmentally Friendly

Most customers often consider how eco-friendly a product is before purchasing it.

If you're one of those individuals, find out below whether Ergoflex and Koala meet the required safety standards. 

The Ergoflex 5G Mattress is OEKO-TEX® Standard 100 and Certi-Pur®-certified.

On the other hand, Koala uses only GECA (Good Environmental Choice Australia) certified foams for its mattress. As such, you don't have to worry about the material containing any heavy metals and ozone-depleting chemicals.

Feature Winner

This one's a tie. Both products perform remarkably well in this regard, as they have taken steps to ensure they meet the necessary eco-friendly standards.

7. Payment Options

If you decide to buy either of these mattresses, what payment methods are available to you?

With Ergoflex, you get the following standard options: 

  • Visa
  • MasterCard 
  • American Express
  • Eway

The following interest-free payment options are also available: 

  • Zip Money

On the other hand, Koala allows you to make payments with the following standard banking methods:

  • Visa 
  • MasterCard
  • American Express
  • PayPal

You also get the option to use the following interest-free methods: 

  • Openpay
  • Afterpay
  • Zip Money

Feature Winner

The Koala Mattress

It's an easy choice here, with Koala edging it as they have more payment options available to customers.

8. Delivery

Knowing how soon you'll get your mattress could significantly influence your buying decision. 

That said, how do both companies measure up against each other on delivery?

Ergoflex delivers purchased products to customers within 24 hours if they placed an order from Monday - Thursday before 2:00 PM. 

If you stay in the metro areas, you can request a specific date and time delivery, weekday after-hours and Saturday morning deliveries for a service charge of $99.95. 

However, specific constraints may hinder customers outside of the metro regions from getting their order within the standard 24 hours delivery time. 

In contrast, Koala offers free and fast delivery within four hours of placing an order for customers within the metro areas. That's if you placed an order before 2:00 PM on a weekday. 

For customers in the regional areas, delivery is still free but may take 1-10 days. 

Feature Winner

The Koala Mattress

It's a no-brainer for us. Koala has a four-hour delivery time for customers in metro areas, which is significantly shorter than the 24 hours delivery offered by Ergoflex.

Standout Features: Ergoflex Vs Koala

If one or the other products have features, the other doesn't have, this is the place to outline them and explain why they make the product standout.

Ergoflex Standout Feature

Ergoflex's high-density visco-elastic foam makes it stand out from alternate options. This foam ensures that sleepers are properly elevated without sinking into the mattress.

Why does this matter? 

Its high density ensures that it's firm enough to support proper spinal positioning. That, in turn, helps prevent back pains. 

You'll also get to enjoy this mattress for longer because higher density foams are less likely to sag.

It gets better:

The high-density foam has cooling gels infused to help with heat distribution and keep you cool. 

Koala Standout Feature

One hundred twenty nights to fall in love or your money back guaranteed, what's not to love about that. 

Koala goes beyond the norm for a mattress in box brands to offer you a 120-night trial. 

This extended trial period exudes confidence in their product and their desire to ensure your satisfaction.
