Koala is the company that put the bed in a box concept on Australia’s map and pretty much laid down the industry standards. The company has recently revamped and upgraded its lineup. It now offers three different mattress models – The New, Calm and Soul.

In this review, we’ll be looking at the upgraded version of the Koala original mattress – The New Koala mattress. In its new avatar, the mattress boasts two firmness levels – medium and firm giving the sleeper the option of two different sleeping experiences.

As a fan of the original Koala mattress, I was curious to see how the company had managed to improve on an already great product. The WhatASleep team put the new Koala mattress through its paces in areas that matter for a good night’s sleep — firmness, feel, support, motion isolation and more.

Let’s tell you what we found.

The New Koala Mattress Review

Mattresses are a matter of personal preference because what’s comfortable or firm for you might not be for others. So our review is a sum of what we found while testing the Koala mattress and our expert analysis and customer reviews available online. We believe it’s a wholesome way of judging a product.

The Koala Mattress Review Summary

The new Koala mattress is a significant upgrade over the original one, though the pricing remains the same. The most standout feature is the flippable dual-firmness comfort layer, allowing you to switch between medium (6) and firm (7) by simply unzipping and flipping the top layer. Zipping the comfort layer is tricky, especially if you’re doing it alone or the first time around. The other upgrade includes a 3-zone support layer which is firmer in the centre and softer around head and foot areas for better spine alignment and enhanced pressure relief.

The mattress blends the sink of the memory foam and the responsiveness of the latex, giving you the feel of gentle conforming and even body support. The mattress does not leave you with a “stuck-in-the-mud” feeling of memory foam. Instead, it’s light, airy, almost like a marshmallow. You can effortlessly switch between positions without feeling bowed down. You experience a good balance of comfort, pressure relief, and support on the mattress.

The mattress is very supportive in both configurations. However, the medium (softer) side offers a bit more give, while the firmer layer is a tad more supportive. Side sleepers, petite folks and select back sleepers would mostly appreciate the medium side, while stomach and back sleepers would do well on the firmer side.

We feel the Koala mattress is a comfortable, accommodating and affordable option for most light to average-weight people under 100 kg in all sleeping positions. The mattress is soft and well-suited for lightweight and petite folks (under 50 kg), who may find other mattresses firm to their liking.

That said, it may not be for everyoneBelow is a checklist of factors that make the Koala mattress a yay or nay for Aussies.

Who might like the Koala mattress?

Who might not like the Koala mattress?

Tl;dr: Overall, the new Koala is our pick for the most comfortable mattress in Australia because of its excellent balance of comfort, support, and versatility. The mattress is suitable for average-weight sleepers (side, back, and stomach) and couples alike in all sleeping positions.

The Koala mattress is a well-rounded product that offers middle-of-the-road features to please most buyers. The excellent after-sale support, quick shipping, friendly returns policy, and transparent warranty terms further make the Koala mattress a solid contender.

Firmness & Feel

So what does it feel like to sleep on the New Koala mattress? Read our first-hand experience below.

How was my sleep experience?

I’m 5’8” and I have an average weight of about 72 kg. In terms of my sleep style, I like to sleep on the side but I switch to back or stomach once in a while. Now I will share how it felt to sleep on the Koala mattress in different sleeping positions.

The medium side of the Koala mattress is an excellent match for light to average-weighted (under 100 kg) side sleepers. The 7cm comfort layer conforms to the body curves pretty well and prevents the pressure from building up along the shoulder and hip regions.

Back and stomach sleepers would find a good balance of comfort and support on the firmer side of the Koala mattress. The lumbar area sinks into the comfort layer with a fair bit of contouring, while the base layer keeps the spine supported at all times.

I don’t think heavier folks (above 100 kg) would do well on the mattress, but that’s general to any all-foam mattress.

With all that said, the Koala mattress is one of the most comfortable mattresses I’ve reviewed.

Transparency Disclosure: We paid for the mattress and did not receive it for free from Koala. The review is not sponsored and all opinions are our own.

How firm is the New Koala mattress?

The New Koala mattress was soft, not plush on the medium side and supportive but not very firm on the firm side. We felt the medium side was 6/10 and the firmer side was 7/10 on the soft-to-firm scale. The top Kloudcell layer is soft and cushiony, while the base of Ecofoam offers good support.

Dual Firmness Comfort Layer

What does the Koala mattress feel like?

The mattress is soft yet responsive to touch. The custom foam blend offers a neutral feel — it’s neither too squishy like the memory foam nor too bouncy like the latex. And the comfort layer hugs you in a cuddle.

As you lay down on the Koala mattress, you first slightly sink into the comfort layer and then experience pressure relief. When you have settled in, the base kicks into action to keep your body steady and supported through sleep.

You tend to sleep “on” the mattress rather than sink in. This means you don’t have to fight that stuck-in-the-mud feeling and you can change positions with relative ease.

The mix of memory foam, latex and medium firmness makes the Koala mattress highly accommodating and comfortable for most sleepers. In that sense, it’s a safe pick.

Average-weight sleepers 58 to 100 kg

Average-sized sleepers should find the Koala mattress comfy in all positions. Side sleepers and select back sleepers should do well on the medium side – the comfort layer conforms to the body and the zoned construction relieves pressure off the shoulders and hips. The firmer side is more supportive, which back and stomach sleepers should find ideal.

Lightweight sleepers Under 58 kg

The firmness and feel of the mattress are directly proportional to the sleeper’s weight. Petite folks put little pressure on the mattress and as a result, they find most mattresses firm. We believe that the medium side is an excellent choice for smaller folks in all sleeping positions. The comfort layer is soft, cushiony and forgiving.

Heavyweight sleepers Over 100 kg

Heavier folks usually find foam mattresses soft as they exert more pressure on the surface than folks with petite or average bodies. So I don’t think Koala, or for that matter, any foam mattress is not a good fit for large folks.

Heavier people should generally look for a hybrid or innerspring mattress wherein the metal coils offer greater support and resilience.

Koala Mattress Construction

The Koala mattress has a straightforward design, comprising two layers of custom-blend polyfoam that are zipped together that size up to total a 10″. The comfort layer is further flippable to change the firmness of the mattress. 

Now let’s see how each layer impacts the overall performance of the mattress.

Koala mattress Construction

Cover: It’s made from sustainable TENCEL-blend fabric, which is breathable, cool to touch, antimicrobial and repels moisture. The cover is non-removable but can be spot or vacuum cleaned.

New Koala Mattress Care Label

Comfort layer: The top layer is made of a dual-firmness flippable 3-inch open-cell foam, which the brand calls the “Kloudcell”. Designed for comfort, it’s soft, bouncy and responsive. It’s also more breathable and traps lesser heat than regular foam.

New Koala Mattress Comfort Layer

Support layer: The base of the Koala mattress is a 7-inch high-density polyfoam or Ecofoam, as the company calls it. This layer is designed with 3 zone support that offers more customised support to the body. It’s slightly softer at the centre to accommodate the hip region while softer around the head and foot area.

The layer also stabilises the bed, prevents excessive sagging, especially around the edges, and supports the sleepers at all points uniformly.

Thickness: At 10 inches, the Koala is a medium-profile mattress. This 10-inch thickness is pretty much standard across all-foam mattresses.


Koala is one of the most comfortable mattresses I’ve ever slept on. It’s a great fit for most types of sleepers and a value purchase. You can get up to $100 off a Koala mattress by clicking on the link below.

Koala Mattress Performance

While firmness and feel are the most critical factors, assessing a mattress for edge support, durability, breathability, and more is also important. 

Let’s see how the Koala mattress fares on these fronts.

Sleep temperature

In my opinion, the Koala mattress is temperature-neutral — it neither sleeps hot nor cool. The open-cell foam promotes airflow and wicks away the heat, which typical memory foam mattresses fail to do. I did not wake up hot or sweaty but habitual hot sleepers may want to try a hybrid or pure innerspring mattress as it sleeps cooler than all-foam mattresses.

Motion isolation for couples

Motion isolation means how well a mattress can absorb the cross-bed motion. If you sleep on a mattress with good motion isolation, you will not realise when your partner rolls out of bed to answer that chocolate craving or nature’s call. Generally, all-foam beds excel in motion isolation, and the Koala mattress is no different. It absorbs and minimises the motion transfer better than an innerspring or a latex or a hybrid mattress. The motion isolation is slightly better on the medium side than the firmer side.

Edge support

Robust edge support has many benefits. For one, you can sleep closer to the perimeter without the fear of falling off. Two, it holds up the shape of the mattress. Three, it prevents sagging around the edges. In that respect, the Koala mattress offers above-average edge support when compared to all-foam beds but falls a bit short when put next to innerspring and latex mattresses.

The firmer side of the mattress provides better edge support than the softer side. However, both sides offer adequate support for light to average-weight individuals.

Sex comfort

Couples need a mattress that is responsive and bouncy for sex. While the Koala mattress is fairly responsive, it is not as bouncy as latex or innerspring mattresses. That said, the firmer side might offer a bit more bounce.

As it’s an all-foam bed, you are spared off those creaking or squeaking sounds that are common in innerspring mattresses.

Overall, the Koala mattress isn’t the best mattress for sex, but it’s still a decent option.


The Koala mattress was first launched in Australia in 2015, re-designed in 2018 and updated in 2021. With over eight years of operating history and real-world customer feedback, it’s safe to say that the Koala mattress is a durable product.

While the company does not publish specific lifespan data, user feedback and our testing indicate that the mattress should last at least seven to eight years with proper care.



Like all-foam mattresses, the Koala mattress has slight off-gassing (chemical smell) but nothing overwhelming. In our trial, the smell dissipated completely after 24 hours.

Company Policies

The devil is in the detail, especially if you are shopping for products online. So do the due diligence.

Mattress removal

Currently, Koala offers free of cost mattress removal in the Sydney and Melbourne area in partnership with Soft Landing.

Delivery (S&H)

Like most online mattress brands, the Koala mattress is rolled, wrapped and compressed in a compact box and easy to lug around. However, what’s different is that the Koala mattress ships in two boxes – the comfort layer in one and the support layer in another. The mattress is delivered to your doorstep (not inside your house) and the logistic company (TNT Express) contacts you beforehand to schedule a delivery time.

The delivery is free Australia-wide and there is an additional shipping fee for New Zealand orders. You can also opt for a 4-hour delivery for metro areas, again free. Typically, the shipping process takes about two to eight business days.

Once your mattress arrives, simply unwrap both boxes and let them expand on your bed frame. Zipping the comfort layer with the base layer may be a bit tricky, especially for the first time. It’s a good idea to seek help from a friend or family member when flipping the comfort layer or setting up the mattress.

Packaging & Delivery

Sleep trial

The Koala mattress comes with a 120-night trial period. However, you can’t return the mattress unless you have tried it for two weeks. The logic here is; your body will take at least two weeks to get fully accustomed to the mattress.

Return policy

Like all online bed-in-a-box brands, you can return the Koala mattress during its trial period and get a full refund. However, the return pick-up is free only in the metro areas — Sydney, Brisbane, Melbourne, Adelaide and Perth. 

For remote or non-metro areas, the buyer has to arrange and pay for the freight to the closest Koala warehouse. This can set you back by $100 to $250 because once the mattress is out of the box, there is no way to deflate and put it back in.

Booking Airtasker would be relatively cheaper. And if you can, drive down to Koala’s warehouse to return the mattress yourself.


The Koala mattress is covered under a 10-year warranty, covering manufactured defects, sagging, and body indentations measuring 25mm or deeper.

Note: Only original buyers can claim the warranty.

Common Koala Mattress Complaints

The Koala mattress is good feedback overall but some users complained it does not offer the best support for overweight or larger folks which even we agree. Similarly, it may not suit those who like resting on firmer beds. So the complaints were over the fact that the mattress is relatively soft. But please note, these were less than 2% of all the reviews we analysed.

Some buyers also mentioned that flipping and zipping the comfort layer was tricky and took some time to get used to. 

How Does Koala Mattress Compare To Others?

It’s always good to compare products in the market before putting your money and trust in something. So here we have pitted the Koala mattress against its biggest competitor: Ecosa mattress.

Koala vs. Ecosa mattress

Koala and Ecosa are all-foam beds and they are quite similar in terms of feel and price offering. With Ecosa, you can enjoy three levels of firmness (medium, medium-firm and firm) by simply shuffling the individual layers while Koala offers two firmness options (Medium and firm).

The other significant difference is that even in the softest setting, Ecosa is firmer than Koala. And so, Ecosa might be a better choice for stomach sleepers, those looking for a more supportive bed. On the other hand, Koala comes with a soft and thick comfort layer and is a better pick for side sleepers.

Ecosa has a leg up on Koala in regards to warranty. It comes with a 15-year warranty while the latter offers a 10-year warranty.

Who should get Koala mattress:

  • Side, back and combination sleepers.
  • Those who prefer a softer mattress.

Who should get Ecosa Mattress:

  • Committed stomach sleepers.

Summing It Up

Koala lives up to Steve Jobs’ famous saying, ‘Do not try everything. Do one thing well’. The new Koala mattress covers a whole lot of sleepers. Plus, it’s reasonably priced and backed by Koala’s much-feted after-sales support.

Overall, the New Koala mattress is a safe and well-rounded pick that should work well for most Aussies. If you don’t like it for some reason, remember you are covered under its 120-night risk-free trial.

Koala Mattress FAQs

We think Koala is an excellent mattress but some may like it more than others. Light- and medium-weight folks who sleep on the side, back and stomach and those who like their bed not too soft or not too firm would mostly enjoy snoozing on this. Heavier people (above 100 kg) or those who like their mattress a touch bit firm might have to look elsewhere.

Yes, the Koala mattress is non-toxic. It’s GECA-certified (Good Environmental Choice Australia), which means, it’s environmentally safe and low on volatile organic compounds (VOCs). The company claims their mattress contains no heavy metals, fire retardant chemicals, phthalates, formaldehyde, ozone-depleting substances, CFCs, and their production is almost free of emissions. The mattress is also vegan and completely recyclable.

Koala mattress is designed in Australia and assembled in China.

You can only flip the top comfort layer, not the whole mattress. The comfort layer goes at the top and the support layer always needs to be at the bottom.

Possibly, because the Koala mattress offers a good balance of lumbar support and comfort. It’s a good idea to try out the mattress and see for yourself if it offers help with your back pain or not.

Generally, memory foam mattresses are considered a better choice for people with back pain as they help reduce pressure points.

Medical disclaimer: If you have pre-existing pain, we recommend you contact your GP first.

Yes. The thick, soft pillow-top comfort layer makes the Koala mattress a good match for most side sleepers.

The choice and quality of materials indicate that the Koala mattress should last for 7 to 8 years.

No. Doing so will hinder the airflow.

Yes. Like most all-foam mattresses, the Koala mattress should be compatible with most adjustable bases.

Yes, it’s safe to use an electric blanket with the Koala mattress. As an added safety measure, the mattress is made of fire retardant material.

Yes, provided the individual slats are no further than 7.5cm apart.

The returned mattresses are donated to one of the 68 charities in Australia. Some of those charity partners are The Salvation Army, Vinnies, and Lifeline Australia.

  1. I am experiencing extreme overheating with my Koala King Single Mattress,
    on a15 deg night I placed a digital thermometer in the bed I woke at 1am and the reading was 33.4 deg.
    I finished the night with only a sheet covering whereas with my old uncomfortable mattress I needed an electric blanket
    This is extremely disappointing as the comfort over-wise is excellent

    1. Hello Peter,

      I’m sorry to hear about your experience. I general foam-based mattresses tend to trap a bit more heat than traditional innerspring mattresses, but it shouldn’t be to such levels. Do you use any mattress protector over the mattress because that often impacts the breathability of the mattress? Alternatively, using a topper may help as well. If your mattress is under the trial period, you might be able to get one for free from Koala.

      You can also try using cotton or bamboo bed sheets, they usually help you sleep a lil cooler.

      I hope this was helpful.

    Hello, I am looking to replace my decade old innerspring mattress. I am confused between the new Koala mattress and Emma comfort. I like my mattress to be firm and not too soft. Please suggest the right mattress for me.
