In a generation of hustlers who survive on gallons of coffee, being able to fall asleep easily is no less than a superpower!

Doing so will not only help you sleep soundly and wake up refreshed, but you'll also be able to lose weight, combat acne, and excel at work. Thus, we've done the research for you and curated this review of the new Koala Calm As mattress.

As most of you know, Koala is one of the best Australian mattress brands that offer a range of super-comfy foam mattresses with firm support. And the best part is its COOLMAX technology, perfect for summer nights in Australia!

What's The Koala Mattress Made From?

Now that you have some idea about the construction and comfort level of the new Koala mattress, let's get into the finer details. Not many buyers pay attention to the material of a mattress, but it is a crucial factor in defining the quality, safety, and durability of the product.

For instance, if you are allergic to any of the materials used in constructing the mattress, it'll only become a matter of distress in the long run. So, to ensure that you enjoy your eight hours of beauty sleep and don't wake up to a mess, here's a breakdown of what goes into making the Koala Calm As mattress.

1. Top Fabric (Comfort Layer)

This 7-cm deep comfort layer is made of polyester and COOLMAX Fibre, both of which feature permanent moisture-wicking tech, making your body feel cool throughout the night. We think this feature makes the Koala Calm As mattress an ideal pick for Australian summer nights and hot sleepers in general.  

2. Anti-slip Base Fabric

The anti-slip gizmo bottom of the Koala mattress is made of 100% polyester with PVC dots. Naturally, the latter creates enough friction on the mattress base to ensure that it won't slide off.

3. Other Fabrics

Other layers of the mattress are also made of 100% polyester and polyurethane foam. The foam is what offers medium-firm support, suitable for any kind of sleeper to enjoy a good night's rest.

4. Anti-bacterial Treatment

Since the Koala Calm As mattress wicks moisture, chances of it attracting bacteria and other nasty microbes are close to none. Yet, the brand has injected the mattress with anti-bacterial additives to keep it safe for you and your kids.

How Does The Koala Mattress Feel To Sleep On?

Comfort is crucial for a mattress, and the new Koala mattress does not disappoint. After all, it was voted as the "Product of the Year" in 2019 and 2021 in Mattress Category, so that says a lot!

First off, the Koala Calm As mattress features a comfortable and cool sleep surface. Thanks to the COOLMAX Technology, the fibre wicks moisture and enhances the drying rate. Additionally, it helps in keeping the comfort layer and quilt cover dry and cool, even on the hottest summer nights.

Next is our favourite part about the new Koala mattress. The flippable comfort layer is unlike any other mattress out there. With its adjustable firmness, you can choose between medium-firm and firm support. Just unzip and flip the double-sided comfort layer, and you get a whole new mattress!

The third section is the transition layer which provides extra support to an aching back by distributing the sleeper's weight uniformly across the entire mattress. Since it features air tunnels that dissipate unwanted heat, you get yet another layer that ensures a cooler night's sleep.

Moreover, you get a high-density reactive layer, known as the NoPressure Adaptive Core, that features precision cut support zones. Hence, it promises a sweet and sound slumber no matter your sleeping position.

Last but not least is the StayPut Edge Support that keeps the mattress stable on any type of bed frame. So, you don't have to worry about slipping off the bed even in your wildest dreams!

And did we mention that it is one of Koala's Zero Disturbance mattresses? Thus, even if your partner tosses and turns throughout the night, your night's sleep will remain uninterrupted.

Overall, considering the adjustable medium-firm support, effective cooling and pressure relief, and stable edge support, the Koala Calm As mattress ensures a healthy sleeping posture.

Weight And Thickness

The dimensions of a mattress play a key role in determining its comfort level. For instance, a thin mattress is as good as a squished out old mattress that does not provide enough support and comfort. On the other hand, if the mattress is too thick, it may get too difficult to get on the bed, especially for children.

Additionally, the weight of the mattress specifies how easy or hard will it be to move it around. This is necessary if you often change the room decor and might want to move your mattress to another room. Or, if you move houses frequently, you'll definitely require a lightweight mattress for easy movement.

However, you need not worry about the aforementioned factors since the Koala Calm As mattress is available in multiple sizes. So, all you have to do is measure your bed frame or the area where the mattress will be kept, and choose one accordingly.

Given below are the dimensions of the different types of Koala Calm As mattresses:

  • Single: 29 x 92 x 188 cm, weighing 25.73 kg
  • King Single: 29 x 107 x 203 cm, weighing 31.43 kg
  • Double: 29 x 138 x 188 cm, weighing 37.16 kg
  • Queen: 29 x 153 x 203 cms, weighing 43.5 kg
  • King: 29 x 183 x 203 cm, weighing 51.57 kg

Among these sizes, we recommend opting for Single or King Single if you sleep alone. The rest of the Koala mattresses work well for couples.

How Much Does It Cost?

The cost of the Koala Calm As Mattress is definitely on the steeper side, so if you've got a tight budget, you might want to look at other options. However, considering its features, quality and warranty period, we think the new Koala mattress is worth the splurge.

  • Single: $980
  • King Single: $1,150
  • Double: $1,350
  • Queen: $1,650
  • King: $1,950

If you need new bedding or just want to go all out, we recommend opting for the whole set, which includes the Koala Pillow and a sheet set. Note that the additional products will be charged separately.

Bonus Features

Now, what good is a mattress that loses shape within the first few weeks? To ensure you don't face any such issues with the Koala Calm As mattress, the brand offers a trial period of 120 nights. Trial periods are especially helpful when buying a new mattress since one takes time to get used to it. And obviously, just one night of good sleep is too short to call it the perfect pick.

Hence, Koala encourages you to sleep, dream, and play on the mattress to ensure that it fulfils your requirements. If not, you can get in touch with the team to apply for a return and refund. For most areas in Sydney, Perth, Brisbane, Melbourne, and Adelaide, the brand offers free returns.

The 10-year warranty is another selling point of this otherwise expensive mattress. So, rest assured that any major damage and blemishes will be covered by the company till the warranty lasts. Notably, Koala offers a 5-year warranty on furniture and a 1-year warranty on bedding products.

Further, you will appreciate that Koala is the only Australian mattress and furniture brand that is a part of the "1% for the Planet" campaign. This implies that it donates 1% of its gross sales for protecting the environment.

In fact, it is one of the B-Corp certified businesses, which speaks volumes about its social and environmental standards.

Other Koala Mattresses

If the Koala Calm As mattress doesn't impress you, why not try other Koala mattresses in different price ranges? Currently, Koala offers three mattresses, including the one featured in this review. So, without further ado, let's take a look at the other Koala mattresses:

1. The New Koala Mattress

The brand's bestseller is a super comfy mattress, an affordable option for those who don't wish to lose an arm or a leg to buy a mattress!

Made of TENCEL Lyocell fibre, the New Koala Mattress will make you dose off in seconds with its soft comfort layer. Underneath that, you have the signature double-sided comfort layer that can be flipped for a firmer support base. And, of course, you get the assurance of zero partner disturbance.

2. The New Koala Soul Mate Mattress

Want to indulge in a luxurious slumber experience? Then the Koala Soul Mate mattress is the one for you!

It features the advanced Sensapole technology, which is a thick, quilted comfort layer and plush cover. Both the layers maintain just the right temperature for you to doze off in minutes. Another distinct feature about this Koala mattress is the bamboo charcoal memory foam that dissipates heat, aids pressure relief, and fights bacteria.

Is This The Right Mattress For You?

In terms of firmness, the Koala Calm As Mattress scores a 6 out of 10, implying that it's neither too stiff nor too plush. This medium firmness makes it a comfy mattress for any sleeping position and those suffering from spinal pain, headaches, and more.

Thanks to the NoPressure Adaptive Core and StayPut edge support, the mattress hugs the body in all the right places, ensuring a cozy yet cool feeling. This feature also provides zero disturbance even while sleeping next to a sleepwalker!

Lastly, the refreshing comfort layer that offers a cooler night's sleep even on the hottest nights makes Koala mattresses a favourite among Australians. Not to forget the anti-bacterial treatment that keeps disease-causing microbes away from your bed.

However, if your budget is restraining you, go for the New Koala Mattress. Or shell out some extra dollars for the Koala Soul Mate Mattress. As you can see, Koala has something for everyone!

Final Verdict

So, to answer your question- yes, the Koala Calm As is an excellent mattress for you and many others who are losing their sleep due to back pain and other health issues.

Thanks to its comfort and cooling technology, this medium-firm mattress is a versatile pick for any room and any sleeper. And since it ensures zero partner disturbance, it is a suitable pick for couples as well.

However, compared to other mattresses, the only minor flaw of this product would be the lack of holding straps. Because, let's be honest- at this price point, one becomes a bit picky!

Other than that, this mattress does not leave us with any complaints. You can even check the Koala reviews on the official website to better understand the comfort level and other factors.

With that, we come to the end of this extensive review-based guide. Hope we could do our bit in your quest to find the best mattress!
