Brand Info - Ergoflex vs Koala.

Founded in 2006 in the UK, Ergoflex was one of the pioneers of the mattress-in-a-box concept. Seeking to overtake big names like Tempur with premium products at low prices, the company expanded to Australia in 2010, where it has continued to gain popularity ever since. Unlike Ergoflex, Koala was founded right here in Australia in 2015. Its founders were driven to not only help people get the night’s sleep they deserve, but to support the environment and eschew predatory mattress industry business practises while doing it!

Construction - Ergoflex vs Koala.

First, you’ll find a removable and machine-washable Tencel woven outer cover.
On the outside is a 70% polyester and 30% Tencel removable and washable outer cover.
Immediately afterwards, there’s a micro-fine inner cover.
Next up, a 100% polyester inner cover.
Once you’re past the covers, you’ll first find a visco-elastic memory foam layer.
The top layer is a breathable, open-cell Kloudcell foam.
Next, you’ll be met with a Cool-Sleep airflow layer.
Bringing up the bottom, you’ll find an ultra-resilient Ecofoam support layer.
Finally, you’ll be supported by a high-resilience foam base.

Comfort, Firmness & Feel - Ergoflex vs Koala.

The Ergoflex and Koala mattresses offer a similar level of firmness, 6/10 and 6.5/10 respectively on the—admittedly subjective—mattress firmness scale, so they should both suit a wide range of sleepers: front, back or side. The difference here comes in the materials each company has used. While Ergoflex’s visco-elastic memory foam and high-resilience base create a secure, motionless, supremely supported night’s sleep, Koala’s Kloudcell foam layer provides strong elements of bounce and reactivity. You’ll still receive support from Koala’s mattress, make no mistake, but it’s a far more balanced option as opposed to Ergoflex’s focused, pressure-relieving design which specialises in providing orthopedic support.

Your average sleeper will likely prefer the “Goldilocks Zone” offered by Koala: not too soft, not too firm. For those with back pain, joint pain, circulation problems or fibromyalgia, however, the Ergoflex mattress might be the way to go.

Sleep Position Ratings - Ergoflex vs Koala.

As foam mattresses, neither of these options offer dedicated edge support features in the way of, for example, reinforced springs or extra firm foam. That’s not to say that they’re outright weak in that department, but for those who struggle getting out of bed (or, heaven forbid, those who find themselves falling out of bed), they may find themselves ill-served here.

Thankfully, things improve when we venture into the realm of motion isolation, especially for the Ergoflex mattress. The Koala mattress may boast more-than-passable motion isolation features thanks to its firm Ecofoam bottom layer, but the Ergoflex takes home the championship belt with the tag-team of that visco-elastic memory foam and the high-density foam base. Top stuff.

Finally, with open-cell foams and naturally breathable Tencel covers, both of these mattresses are perfectly suited to keeping you cool in the hot and sweaty Australian nights. The Ergoflex mattress takes it a step further though. How? It’s all down to that Cool-Sleep airflow layer, which works to disperse your body heat out through the mattress. It’s pretty high-tech as far as mattresses are concerned; we’re impressed.

Buyer Feedback - Ergoflex vs Koala.

On, both mattresses stand tall with aggregated buyer ratings of 4.8/5 for the Ergoflex (out of 1,464 reviews) and 4.5/5 for the Koala (out of 3,532 reviews).

Arthritic buyer glob03 from Wide Bay-Burnett, Queensland is thrilled with their Ergoflex purchase:

“I like a firm mattress, and was worried this one would be too soft, but it’s perfect, it seems to support my body which ever way I lay and as I’m a very active sleeper this is certainly a bonus. I bought this mattress to go on an adjustable bed base, and they seems to work perfect together. The mattress certainly doesn’t aggravate any of my arthritic joints.”

Sally Petersen from Sydney, on the other hand, has become a Koala devotee since buying her Koala mattress:

“I can’t tell you how much I love my Koala Mattress, I’ve actually had it for some time now and have since purchased a few other items from Koala and even convinced my housemate to get one!”… “I never want to get out of bed and have found that my body aches and pains have eased which surprised me! I didn’t think a new mattress could have such a positive impact on my sleep. Not feeling like an old granny when getting out of bed is the best feeling.”

Final Verdict:

Both Ergoflex and Koala are welcome runners in the Australian mattress-in-a-box race, each taking a different approach to an all-foam mattress design. With Ergoflex, you receive superlative pressure-relief and unrivalled motion isolation features (for the price that is). With Koala, you receive a balance of support and reactivity that probably won’t be suited for those with serious pain issues, but will certainly suit a wider range of non-ailed sleepers. Plus, with the company’s environmental focus, you can feel genuinely good about your Koala purchase!
