Koala mattress review: Best mattress in a box?

Modern day humans are a funny bunch. We spend about a third of our lives either sleeping or trying to.

Yet we often use our mattresses long past their intended point of expiration until the once-supportive springs dig into our backs – an aching reminder that we still haven't gotten around to properly investing in a good night's rest.

Thankfully online mattress startups are shaking things up – not only by bringing costs down, but also by simplifying the research required to find the best mattress for your individual needs.

I'm still blown away that you'll get delivery within four hours if you live in one of the five cities mentioned above and order an in-stock item before 2pm on a weekday.

It's immediately clear that Koala has taken great care in customer service and convenience. You even get a text message when your order is on the way. You can choose to have boxes left if you can't be home, and select metro areas can receive deliveries up until 8pm weekdays or on Saturday mornings. And though the standard couriers can't come inside (or carry boxes up more than three flights of stairs), Koala's premium delivery option gets you a two-person crew that'll bring your mattress upstairs, set it up in the room of your choice and remove any packaging.

One final note here: for Sydney and Melbourne, Koala has partnered with Soft Landing, a mattress recycling social enterprise that can remove and recycle your old mattress. Some council pick-up allowances are better than others, so this service worked great for me. It saved me time, hassle and money.

A quick shout out to whoever came up with Koala's long, slimline box design. In my case, it definitely eased the pain of navigating doorways off a narrow hallway. It's great for terraces and flats.

When it came time to unwrap the Koala mattress, we triple checked, but we didn't receive an instruction booklet, little cutting tools – or even a cuddly Koala toy in the box like I've seen others get. The truth is, you really don't need a guide. It's pretty straight forward for two people to pull out the rolled-up mattress and place it on the bed base. By the way, if you've got slats, Koala recommends they be no more than 7.5cm apart. It also cautions against using the mattress on the floor due to reduced air flow.

As you can see in the video on this page, we couldn't find any markings on the plastic for which side of the mattress should face up. Inevitably – like buttered toast always falling face down – we got it wrong. But a quick and easy flip over and we were back on track.

We took the plastic off and we quickly had one expanded mattress – mostly. While you can sleep on the Koala mattress soon after unboxing, the company says it can actually take about three to five days to come back to full feel.

Koala says its mattress is designed to "distribute weight evenly" and "not to sink or bend in the middle" and is for "people of all shapes and sizes". And sure enough, you'll find plenty of reviews online from users who find the zoned support helpful to reduce back pain. This also makes the Koala suitable for back, side and stomach sleepers alike.

But again, everyone is different – and that's the joy in being able to try the Koala risk free for yourself. What have you got to lose?

Coming from a traditional pocket spring mattress, my first impression was just how much firmer the Koala mattress is. At first, it was kind of like sleeping in a hotel. And without my old topper, the Koala (at 23cm) is noticeably much lower in height and closer to the floor.

Speaking of which, the partner disturbance/anti-transfer capabilities of the Koala mattress were highly welcomed in my little family. Taking turns to get out of bed and settle my daughter in the middle of night just got a whole lot easier. Pro tip: a snug fit on your bed base that avoids sliding movement is equally important.

If you've got little ones, it's worth noting that Koala doesn't recommend using a mattress protector with its mattress. This is not only because it would reduce airflow, but also because you've already got a removable, hand-washable cover with underside zipper. You're also able to use your favourite old topper or electric blanket, but the same breathability issues could come into play.

I tested the queen-size mattress Koala sent us to review with Koala bedding I purchased myself: super-smooth TENCEL sheets and pillow cases. Your favourite linen should also fit just fine as Koala uses standard Australian sizing – see our table.

Koala says to expect the mattress to last about 10 years. I'm only a little over two months in, so I haven't noticed any permanent sinking spots across the sleep surface.

The company provides a 10-year limited warranty on the mattress, which covers "visible indentation greater than 2.5cm... that is not associated with an indentation or sag which results from use of an improper or unsupportive foundation or adjustable bed base."

Out of the box, it can also take a few hours for the "new mattress smell" common to foam mattresses to fade. That's the materials "off-gassing". Some people are more sensitive to it than others, so it's hard to say how long you'll need to let your mattress breathe before you're happy to use it. In my case, we turned the ceiling fan right up to speed ventilation, left the bedroom door open and happily slept on the mattress the next night. It took about a week for us to forget there had ever been any out-of-box odour.

Koala says its mattress has been "rigorously tested for all the nasty chemicals that can be found in other mattresses." That means it contains no phthalates, heavy metals and has low volatile organic compound (VOC) emissions, though the company doesn't share any certifications concerning laboratory testing. The Koala mattress is also fire retardant, "using a flame retardant stockinette [Nylon netting], not dangerous chemicals."

Environmentally, the Koala mattress is proudly vegan and made from GECA-certified foam (Good Environmental Choice Australia standards of environmental friendliness). And when you buy a Koala mattress, you also symbolically adopt a sick or injured Koala, through a partnership with WWF Australia.

Pricing is comparable between Koala and Ecosa, and both have expanded into other products like sheets and pillows. Koala also sells a special bed base and even a flat-pack sofa. What sets Koala apart? It's the discounted bundles on those extra items along with its mattress and sheet essentials.

Though some beds/bases from certain Swedish furniture stores are smaller than Australian standards, "you can squeeze the [Koala] mattress into a bed frame up to 3cm smaller than the mattress" with no problems.

In many ways, online mattress brands like Koala in Australia, Casper in the US, Simba in Europe and Endy in Canada have arguably matched the convenience and reasonable value-for-money of IKEA, while moving onto new foam technologies even as the Swedish giant continues to roll with springs, memory foam and latex.
