Why we love Koala Calm As:

The Koala Calm As mattress is a mid-range mattress with excellent value for money. Koala is one of the most popular mattress-in-a-box brands, and for good reason. With the entry-level New Koala and premium Soul Mate mattress, the Calm As mattress is the best of both worlds, providing a great night's sleep at a budget-friendly price.

Is The Koala Calm As Right For You?

The Koala Calm As mattress forms the mid-range option in Koala’s mattress range which includes the entry-level (New) Koala Mattress, and the flagship Soul Mate Mattress. Let’s take a look at if it’s the right mattress for you!

Who’s Going to Love The Koala Calm As Mattress?

  • Hot sleepers: The Koala Calm As (like all of Koala’s range) features unique COOLMAX®️ technology which helps enhance the mattress’s drying rate, while also helping you to feel cool and dry.
  • Couples: The motion isolation of the Koala Calm As is top-notch. The dense foam base locks in movement and helps you enjoy a good night’s sleep, even next to a restless partner. Meanwhile, the soft comfort layer may cause some sinkage, which may restrict movement for sleepers and make it more difficult to switch sleeping positions. 
  • People with back pain: The Koala Calm As evenly distributes your body weight, which helps keep your spine in a healthy, neutral posture. Its medium-firmness (even in its firmest setting), makes it a great option for people with back pain.

Who Should Consider Alternatives To The Koala Calm As Mattress?

  • Stomach sleepers: The Koala Calm As mattress does tend to sink in at the hips, which may pull your lower back out of alignment if you sleep on your stomach.
  • You need excellent edge support: Being a foam bed, the Calm As doesn’t offer as much edge support as competitor mattresses.

The Koala Calm As Mattress Video Review

The Koala Calm As mattress is a mid-range mattress with a whole lot of bang for your buck. And with plenty of good customer reviews, I had to put it to the test myself. Check out my full review below.

The Koala Calm As  Mattress Firmness

The Koala Calm As mattress comes in two firmness levels: medium-firm (how it’s shipped), and firm. You can switch between these two levels of firmness by flipping the mattress.

I’d say the medium-firm Calm As is about a 6.5/10 on the mattress firmness scale, while the firm side is about a 7/10. In all honesty, the difference between the two firmness settings is pretty negligble.

When compared to the similiar Ecosa mid-tier mattress (The Ecosa Mattress), it’s noticeably softer, so if you’re after a firmer foam mattress, it might not be right for you.

Is The Koala Calm As Mattress Good For Larger (100kg+) People?

According to Koala’s FAQs, the company undertakes rigorous testing on its mattresses to create a product that they say is the perfect comfort for anyone, no matter your shape, size or how you prefer to sleep.

In saying that, from my point of view, the Calm As certainly is one of the thicker mattress-in-a-box mattresses, so I’d be confident in saying it’s good for heavier folks.

What Does The Koala Calm As  Feel Like?

The medium-firm version of the Calm As certainly is comfy, with an almost plush feeling. It’s not as foamy or spongy as the New Koala mattress and is definitely more responsive than the base model. In saying that, it’s not as responsive as say a hybrid mattress because it doesn’t have the innerspring that hybrid mattresses do.

The firm version feels much the same, but perhaps a little more supportive. Either way, both firmness configurations feel sturdy and well balanced.

Is The Koala Calm As Mattress Cooling?

Koala has certainly worked hard to make the Koala Calm As mattress as cool as possible. This includes the cover of that mattress that’s made with what Koala calls COOLMAX technology (it features on all their mattresses). These polyester fibres are designed to wick away any moisture (AKA sweat) so you stay cool and dry all night. The third layer then has air tunnels to help air move freely around the mattress, which should also help on hot nights.

How Is The Edge Support Of The Koala Calm As Mattress?

The Calm As has what Koala calls the StayPut edge support, which is not featured in the New Koala, and it’s a pretty unique feature as memory foam mattresses don’t typically come with edge support, and I did notice a difference in edge support, but it’s still not as supportive as say a hybrid mattress’s edge support.

How Is The Responsiveness Of The Koala Calm As Mattress?

As is typical with a foam bed, the Koala Calm As Mattress doesn’t have the natural bounce and responsiveness of many innerspring mattresses. As such, if you move around a lot (either by changing positions while sleeping or for some adult-only activities), you may have a better time sleeping on a hybrid mattress.

However, for a foam mattress, I’d say the Calm As mattress has pretty decent responsiveness overall.

Motion Isolation: Is It Good For Those Who Share A Bed?

Koala prides itself on its excellent zero partner disturbance guarantee. And, with 5 layers of pressure-absorbing foam, it’s definitely true that partner disturbance (either from a partner or beloved bet) is minimal.  

Koala Calm As Mattress Construction

The Koala Calm As mattress has 5 distinct parts to it:

1. Sleep surface

The separate comfort layer is 7cm deep and also has a 1cm Quilted Plush Cover. The top cover of this comfort layer is made of Polyester (63%) and Polyester (COOLMAX® Fibre, 37%). This cover has been designed specifically for moisture absorption and cooling.

2. Comfort layer

This outer cover encases a double-sided Kloudcell™ comfort layer (which is what you flip to change the firmness level) and is made from Polyurethane foam.

3. Transition layer

The transition layer sits over a ‘ZoneOut Transition Layer’ and uses three targeted support zones to help disperse weight and provide nice support for your lower back support. The transition layer also comes with special “air tunnels” which are designed to help with temperature regulation and overall airflow.

4. Support layer

This is the main support structure of the Koala Calm As Mattress and features a ‘NoPressure Adaptive Core’. This is the part of the mattress that provides a good amount of pressure relief.

5. Edge support

Finally, we have the edge support layer. The Calm As mattress comes with a special perimeter structure that’s designed to help edge support, which Koala has named the ‘StayPut Edge Support’ layer.

How Much Does The Koala Calm As Mattress Cost?

King single $1,190

Shipping & Unboxing Of The Koala Calm As Mattress

The online buying experience is fairly easy and straightforward. You can select your mattress, enter a discount code (if you have one – typically Koala gives $100 off if you sign up to their mailing list), and then choose your delivery window.

Due to the design of this mattress, it comes in two separate boxes, one for the mattress base, and the other for the flippable comfort layer. It makes it easy to maneuver, but also is a lot of packaging, which is annoying.

Delivery of the Koala Calm As Mattress is free and the mattress can be delivered Australia-wide. Koala offers an impressive ‘same-day delivery’ to major metro areas, and sometimes a free 4 hour delivery in Sydney, Melbourne, Brisbane, Perth and Adelaide.

Koala will also pay for the pickup and recycling of your previous mattress – and even recycle the packaging from your new Koala mattress. The offer only applies to Sydney metro customers.

Due to the ‘2 box’ system, expect to take some time unboxing and setting up your Calm As mattress. It’s definitely best to have a friend help you out.

It also comes with a cute Koala toy, but what would have been more handy is a cutting tool (Ecosa and Emma both provide plastic cutting tools and it makes the process a lot smoother and less risky than using scissors).

Koala Calm As Mattress Warranty Information

What Is And Isn’t Covered By The Koala Calm As Warranty

What is Covered

The Koala Warranty covers any physical damage, flaws, major blemishes, or manufacturing defects in both materials and workmanship when the mattress is used for its intended purpose (i.e sleeping). You get a good 10 year warranty which starts from the date of pruchase.

What isn’t Covered

  • Normal wear and tear, including minor pilling, fading, stains and discolouration, and softening of the product that does not affect performance.
  • Minor changes or settling to foams or cushioning layers that may cause visible or unseen indentations of less than 25 mm.
  • Slight variations in colours, small knots or spotty inclusions.
  • Damage caused by improper use, cleaning, maintenance, treatment, or storage
  • Damage caused by alterations or modifications made to the mattress or when its used not for its intended purpose.
  • Mattresses used for commercial purposes

Koala Calm As Mattress Trial Period & Returns

Koala offers the longest trial period of all the mattress in a box brands with 120 nights. In most areas of Sydney, Melbourne, Brisbane, Perth and Adelaide they offer free returns.

They have a minimum 7 day trial period before you can start a returns process within your 120 night trial. And, if you don’t feel the Koala mattress is right for you after 7 days, you will be able to return it, no questions asked.

Addressing Koala Calm As Mattress Complaints

As such, there aren’t too many complaints against the Calm As mattress, but it is a relatively new product. But so far, praise for the mattress from consumers is overwhelming.

Personally, I found the zipper to connect the Kloudcell layer to the support base fiddly to manevour. And perhaps more importantly, I’d have liked to have felt more of a difference between the medium-firm and firm layers. As I mentioned, the difference is pretty negligible.

Comparing The New Koala Vs Calm As Vs Soul Mate 

Trying to decide which Koala mattress is right for you? What’s the difference between the products? They’re all flippable memory foam mattresses at the end of the day. While the three models are very similar, they’re really designed to meet differing budgets. So while the design isn’t all that different as you go up in models, the materials used do go up in quality and are more comfortable. 

Here’s what I’d recommend:

For a mattress on a budget that meets all your basic needs, choose the New Koala.

If you sleep hot and need a mattress with more breathability, choose the Calm As.

If you’re after a premium mattress and high-level pressure relief for backaches and pains, choose the Soul Mate.
