We’ve been sleeping on Australia’s most-loved, most talked about, most recognised, most *insert name here* mattress and we’re bringing you the stone-cold truths about the new Koala mattress range. What’s changed, stayed the same, and improved? We’re here to unbox everything there is to know about the Koala mattress so you can make the right choice for your sleeping self.

Originally the brainchild of two mates from Byron Bay, the Koala range first hit Australian bedrooms back in 2015. It changed the mattress game in Australia forever, and their new revamped model is highly anticipated and a long time in the making.

Koala spent the last few years rigorously testing the new mattress lineup before bringing it to market. Listening to customers, conducting research and developing a range of options before ultimately deciding to tier the selection to fit every budget. Here are our thoughts.

The Digest

For our tests, we chose the middle of the road ‘Calm As Mattress’ because it’s likely to be the most popular amongst consumers and the one most people will sleep on every day. In short, The Calm As mattress has been a joy to sleep on. While we’ve been conditioned to take a list of features with a grain of salt when it comes to mattress technology, you can really feel them coming together to create the perfect night’s sleep with this model.

The 3-zone support is immediately noticed and supports you in all the areas that matter. Specifically, it stops you from falling into the foam mattress, a massive concern amongst mattress in-a-box sceptics. This technology is instantly backed up by multi-layered zoning, zero disturbance technology (the old red wine glass trick) and StayPut edge support that keep you from rolling away. There are plenty of misconceptions that a foam-mattress has no ‘spring’ and feels lifeless, but this simply doesn’t apply to the new Koala range.

We set our flippable top layer to the firm side – mimicking our previous mattress in firmness – and had absolutely no issues sleeping. In fact, we’ve never had a better sleep than with the Koala Calm As mattress. When combined with the new Koala Sheet Set it’s truly a magical hotel-like experience every night.

We’d be hardpressed to find something we didn’t like about the new range. A month of quality full nights rest can only be attributed to the mattress. It was the brand’s goal and aim to reduce the national sleep deficit of 5.7 billion hours, and we think they’ve accomplished it.

The New Koala Mattress

We were one of the lucky recipients of the new ‘Calm As’ mattress before it hit the market. This gave us a little head start when it came to testing and review, and now, after a month of sleeping on Australia’s most talked-about mattress, we can share our full and honest thoughts.

Purchase and Packaging

The whole benefit behind the mattress-in-a-box solution is in the seamless purchase and delivery process. Gone are the days of rocking up to your local mattress store and being treated to a sales assistant who tries to convince you that the $4000 mattress is exactly what need. Koala has made the process easier, simpler, and quicker with an intuitive and easy to use website.

Upon delivery, we were greeted with two boxes. One includes the main mattress base layer and the other houses the ‘comfort’ layers including the flippable top. The boxes are BIG so be prepared to find some space to house them while you remove your old mattress. Koala has teamed up with Soft Landing in Melbourne and Sydney (selected areas) to remove your old mattress for FREE.


The video linked above will demonstrate the setup process in general, but we’ve provided a few key tips for those who are looking to make the most out of their new bed.

Once your old mattress is out of the way, we recommend clearing a space and laying out the foam mattress. If your bed base is flat, that would work perfectly, otherwise, you’ll have to use a separate room and then transfer the bed back onto the bed base after a few hours. It’s worth noting that if you’re the owner of an IKEA bed base (we own the MALM) the Calm As will be a tight squeeze but it just fits.

Zipping the mattress together is easy as it gets. You CAN sleep on the bed straight away, but it won’t reach its comfiest until around 48-hours after releasing it from the plastic. We let ours rest overnight and slept on it the next day. The only decision you have to make is how firm you want your top layer to be, we chose firm.

Construction and Materials

You read a lot about all the features mattresses have, but in reality, you’re always sceptical if it’s nothing more than marketing jibberish. In our personal testing of the new Koala Mattress, we can assure you that every single feature outlined below has a real-world effect on your sleep. You might ask yourself, how complicated can a foam mattress be? As it turns out, very complicated (and comfortable).

  • 7cm Flippable Kloudcell Comfort With COOLMAX Technology
  • 1cm quilted plush cover
  • 3 Zone Support
  • Multi-Layered Zoning
  • StayPut Edge Support
  • Zero disturbance technology
  • First GECA certified mattress
  • CertiPUR-US certified foam
  • Anti-Slip Bottom
  • Anti-Bacterial Treatment

The new Koala mattresses are the first fully certified GECA mattresses in Australia. That means you’re supporting environmentally preferable production and consumption. This is a massive step in the right direction and one that shouldn’t be taken for granted. How often do you drive and see mattresses sitting on the side of the road destined for a landfill? Too often is the answer, but with the help of Soft Landings and Koala that disappointing image might disappear sooner rather than later.

So how does all this technology translate to real-world comfort? Well, the secret to staying asleep for longer is staying cool. It turns out it’s not all about cushion and support, and in our testing, we have to say their new COOLMAX technology works wonders. We’ve never had better sleeps, and we’ve never stayed cooler thanks to the speciality fibres and permanent moisture-wicking technology. Unlike wearing a scratchy set of athleisure with “moisture wicking” tech, you can’t even tell it’s working until you wake up 10-hours later feeling comfy and sweat-free.

Next on our list of favourites is the support. Multi-layered Zoning is the feature that immediately removes the foam mattress sceptics from the conversation, it’s not just a ‘piece of foam’ it’s clear from the moment you lay down that you’re going to be supported from all angles no matter how you sleep. With three high density targeted support zones to disperse your weight and provide extra support for your lower back, you can really feel the technology working.

In our case, we’re face down sleepers (with the odd leg kick out) so support is not super necessary. Back sleepers and restless sleepers will be able to appreciate the extra support and secureness, and they’ll love the addition of StayPut Edge Support that’s very noticeable (zero roll-overs). You’ll avoid those leg kicks in the middle of the night from your partner who’ll fully appreciate the zero-disturbance technology (wine glass trick) just ask us how we know. Deciding on what side of the Kloudcell flippable layer you rest on is the only point of contention!

We tried very hard to find something we didn’t like about the new Koala Mattress range, but it’s very hard to critique a lineup with so much research and development involved. You simply can’t argue with additional features such as a 120-night free trial, 10-years warranty, mattress removal, and free shipping.

While our initial plans for the mattress were to review it and move it into a guest house, we’re replacing our mattress (that cost 3x the price) for the new ‘Calm As’ Koala mattress and we think you should too. If you’re sitting on the fence when it comes to a mattress-in-a-box solution, sometimes the big name really has the technology and R&D to it up, the new K0ala range is a no-brainer in our opinion.


Here is the cost breakdown for the new Koala ‘Calm As’ Mattress as tested here. We will note that at the time of writing there are potential delays being experienced by the brand due to customer demand. We recommend checking the website for further details – linked here. Let us assure you it’s worth the wait!
