Why we love the Koala Soul Mate:

The Koala Soul Mate is a premium mattress in a box, and while it has a pretty big price-tag, for all it delivers, it's certainly worth it if budget isn't a concern for you. Plush yet firm, this mattress packs a punch in all the right areas.

Who’s Going to Love The Koala Soul Mate Mattress

Koala Soul Mate Mattress Review

There are a couple of reasons why The Koala Soul Mate not be for you, including:

  • It’s by no means a budget mattress – it sits at the pointy end of mattress prices

The Koala Soul Mate Mattress Firmness

The Koala Soul Mate 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 6/10 on the mattress firmness scale, while the firm side is about a 6.5/10. In all honesty, the difference between the two firmness settings is pretty negligble. And overall, it’s not a particularly firm mattress.

When compared to the similiar Ecosa Pure premium mattress, it’s noticeably softer, so if you’re after a firmer foam mattress, it might not be right for you.

Is Koala Soul Mate 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 Soul Mate is 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 Soul Mate Feel Like?


The medium-firm version feels quite spongy, but it’s definitely very comfortable. Despite being on the softer side, it still offers great pressure relief. And, it’s a bit more responsive than the typical foam mattress thanks to its unique foam springs.


Again, there’s not a huge difference between medium-firm and firm, but as expected, the firm side is slightly harder. It’s comfortable and absorbs body weight well.

Is The Koala Soul Mate Cooling?

Koala has certainly worked hard to make the Soul Mate 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 Soul Mate Mattress?

How Is The Edge Support Of The Koala Soul Mate Mattress?

The lack of side handles is disappointing though, particularly at this high price point. Edge support is quite firm though, so you should be able to use the entire surface of the mattress without fear of falling off the edge.

How Is The Responsiveness Of The Koala Soul Mate Mattress?

The Koala Soul Mate features 5 zone adaptive foam springs that contour to your body. These springs certainly help make the mattress more responsive than your typical all-foam mattress.

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

I’d say motion isolation on The Koala Soul Mate is not as good as competitor products, for example the Ecosa Pure. It’s certainly decent enough, but I think the mattress’s foam springs and susbequent responsiveness means it’s not as good as deterring motion transfer.

Koala Soul Mate Mattress Construction

The Koala Soul Mate Mattress can be broken up into 5 layers.

1. Sleep surface

This is a seperate comfort layer which is 9cm deep, and also features a 2cm Quilted Plush Cover.

2. Comfort layer

This outer comfort layer encases a lippable Kloudcell™ Comfort + Sensapole® Sleep Surface. This uses Koala’s Trademark Kloudcell™ (Polyurethane foam) and is what allows you to switch between medium-firm or firm.

3. Bamboo Charcoal Memory Foam

The bamboo charcoal memory fiam layer is an extra comfrot layer, and also helps with temperature regulation. It’s also known for its antimicrobial properties.

4. Support layer

The bulk of the mattress is made of a ‘5 Zoned Adaptive Foam Spring’ structure. These foam springs are made to provide dynamic support, and give excellent airflow.

5. Edge support

Finally, the Koala Soul Mate has special ‘StayPut Edge Support’ to help with – as the name suggests – edge support.

How Much Does The Koala Soul Mate Mattress Cost?

The Koala Soul Mate only comes in 3 size – double, queen and king. Check out the current pricing below.

Shipping & Unboxing Of The Koala Soul Mate 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.

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 Koala Soul Mate 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 Soul Mate Mattress Warranty Information

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 Soul Mate 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 Soul Mate Mattress Complaints

As such, there aren’t too many complaints against the Soul Mate mattress, but it is a relatively new product. However, some customers have suggested the mattress – even on it’s firmest setting – is still too soft, which I can somewhat agree with. Some have suggested an issue with smells as well – but that “new mattress smell” is pretty standard across the mattress-in-a-box industry in my experience.

New Koala Vs Calm As Vs Soul Mate 

How do youo decide between the three? 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.

How a mattress feels is very subjective, so take this advice with a grain of salt. As you can maybe guess, I personally enjoyed sleeping on the Soul Mate mattress best. It was both plush and firm at the same time, kind of like what you’d expect from a really good hotel bed. 

I also really enjoyed sleeping on the New Koala as it was great for a firm, pressure-relieving mattress, and I found it firmer than the Calm As a mattress, which is worth noting if you enjoy a firmer mattress.

And the Calm As really is an excellent middle-ground mattress – excellent value for money and just overall very comfortable. 

In terms of firmness, the New Koala is the firmest, followed by the Calm As, and finally the Soul Mate. 

In terms of thickness, you’ve got the Soul Mate, followed by the Calm As, and then the New Koala is the thinnest. 

Final Verdict

I had high hopes for the Soul Mate mattress, and it certanily delivered. The Soul Mate was a dream to sleep on. Over all, the Soul Mate did everything it’s intended to do, and I loved it. Is it worth $2,790 when there are similar mattress in a box products (like Ecosa’s Pure mattress which is over $500 cheaper), that’s debatable. But overall, it’s definitely an excellent mattress.
