Anyone with a good mattress will tell you it's worth its weight in gold. But that doesn't mean a new mattress costs its weight in bullion. Buying a new bed used to take hours of driving around showrooms, forking out thousands, and lugging heavy loads up and down staircases. Since then, the world has welcomed the era of online mattress shopping. Nowadays, buying a new mattress is about as easy as ordering a pizza.

While many of the mattresses you can buy online are made of memory foam, there are also pocket spring, latex, and hybrid beds. The best mattress is soft and breathable, while still being firm enough to offer support where you need it. If you prefer a softer bed, you can always add a mattress topper. Some online mattress brands also provide you with a few firmness options, so once you've got a great pillow, you have everything you need for a great night's rest.

But before we get to the good bit, here's a quick medical note. Many reviews made claims about how good a mattress was for bad backs, sore necks, or painful shoulders. As we aren't medical doctors, we encourage you to check with a health professional if you have a chronic condition that may be impacted by your new mattress. On that note, let's take a look at 9 of Australia's best online mattresses.

How we picked

If you thought the rabbit hole in Alice in Wonderland was big, wait until you've tunneled into this one. The Australian online mattress universe is bigger than Queensland, so we needed a well-travelled guide to get started. CHOICE, Australia's biggest consumer advocacy group, was the first stop on our journey. We took their reviews into consideration, adding 10 of these mattresses to our list.

Not every traveler wants the same kind of holiday, so we cross-referenced CHOICE's expert opinion with the real expert opinions of everyday Aussies. Looking at ratings on ProductReview.com.au, we added the mattresses that scored higher than 4 stars over 100+ reviews to our list, and compared them to the CHOICE reviews. After picking the top 9 from each, we categorized our choices. Some mattresses were similar to, or bested by other mattresses, so we culled those with the lowest reviews on ProductReview.com.au. That's how we ended up with our list of Australia's best mattresses in a box.

The 9 best mattresses in Australia

Best for most -> Sleeping Duck

Sleeping Duck

The Sleeping Duck mattress was a clear winner across all the reviews - and not just across the bed in a box category. Nearly 3,000 Australians gave this mattress 5 stars on ProductReview.com.au, and it's also reviewed by CHOICE, Australia's biggest consumer advocacy group. The Sleeping Duck mattress won a Good Design Award for its innovative design, and it's so well thought-out that it even impressed the Shark Tank judges. 

So why is the Sleeping Duck Australia's fave? We reckon its secret lies in its firmness. When you buy a Sleeping Duck mattress, you can choose between medium and firm. If that doesn't work, you can change your choice within the first 100 nights, free of charge. We also love that you can choose a half-half mattress - firm for you, medium for your co-sleeper, for example. And if that still doesn't float your boat, they can customize your mattress even further, adding or removing support where needed.

The Sleeping Duck mattress is made with trademarked Hyper-Adaptive foam, which is 8x more breathable than latex and memory foam. In other words, it's made with our climate in mind. This Australian-made foam relieves pressure while retaining its shape. The mattress has a naturally antimicrobial bamboo cover, and 5 zone pocket springs in the base. One pregnant reviewer noted the new-bed smell, but almost every single Sleeping Duck mattress review shows Aussies love these ingenious mattresses.

Best latex -> Zenna

Zenna

The Zenna mattress is your online solution to a latex mattress. It's one of the most eco-friendly options on our list, too. Natural latex mattresses like the Zenna are ideal for you if you lie awake at night worrying about the environment. We're not saying it'll solve climate change - it's just that the Zenna is so comfortable you'll find it hard not to fall asleep. It also has a sustainably-made bamboo cover that zips off easily for chucking in the wash (on 'eco mode,' of course).

As latex makes for a firmer mattress, the Zenna is best for stomach and back sleepers. Natural latex is biodegradable because it comes from the sap of rubber trees, and the Zenna latex is Oeko-Tex certified to be free from 100 harmful substances. Natural latex is also ideal for allergy-sufferers, as it repels moisture, mildew, and dust mites. Like many other online mattress brands, Zenna offers a 100-day trial, so you can give this mattress a good test-run first.

Aussie consumers love their Zennas. At $1,595, it's not the cheapest mattress, but still scores nearly 5 stars on ProductReview.com.au in both the overall and value for money categories. Reviewers rave about Zenna's customer service, and more than one person said it's the most comfortable mattress they've ever slept on. Several consumers also commented that it helped with bad backs. What's not to love?

Best for budget -> Emma

Emma mattress

The Emma mattress is proof that German engineering doesn't always cost an Audi and a leg. These beds have won nearly 30 best mattress awards across Europe, as well as the hearts of Aussie consumers. The breathable Emma mattress is reviewed by CHOICE. It has 7 support zones to keep body pressure distributed evenly, and most reviewers on ProductReview.com.au said it was medium to firm mattress. Many have commented positively about the product's price, comfort, and customer service.

One of the downsides is that Emma's foams are made in Germany, so the carbon footprint of these mattresses has to be higher than locally-produced ones. It was also difficult to find out exactly what the 'eco-friendly' foam was made of, or why it was so breathable. Compared to other mattress websites, Emma didn't give us much specific information about its materials. We guess that for $799, you're probably not paying for fancy marketing or carbon offsets.

Best memory foam -> OneBed

Onebed mattress in a box

The OneBed is one of the best memory foam mattresses you can buy online in Australia. Memory foam is known for its softness and support. This makes it a dream for side sleepers whose weight is concentrated so they sink into the mattress more. Two of memory foam's drawbacks are that it retains heat, and can be too soft for some. The OneBed cleverly side-steps these problems with its interchangeable layers, so side, back, and stomach sleepers can all sleep soundly no matter the season.

Like the Sleeping Duck, the OneBed's customizable top layers can be arranged for a firm, medium, or medium firm sleep. These three top layers are made of memory foam and latex. By using latex, air moves more freely around the mattress' surface, improving breathability. On the flipside, the mattress is coolest with the latex layer at the top, so you may have to toss up between firmness and temperature. The OneBed mattress has a 15-year warranty, which is longer than most beds you can buy in a box, although every mattress on our list has at least a 10 year warranty.

The OneBed scored nearly full marks with over a 1,000 Aussie consumers on ProductReview.com.au, and it was also reviewed by CHOICE. Like many other memory foam and latex mattresses, the OneBed passes the 'wine glass' test, absorbing force without waking up your co-sleeper, or tipping your precious glass of vino. Several OneBed reviews confirmed that it reduced partner disturbance. This makes it ideal for families with children, or for anyone who likes the odd glass of cab sauv in bed.

Best for side sleepers -> Koala

Koala mattress and wooden bed frame

The Koala mattress is our pick for side sleepers because it provides excellent alignment for side sleepers' necks and spines. The majority of happy Koala campers are side sleepers on ProductReview.com.au, and one of our Cosier team members is among them. Our Cosier side sleeper loves this mattress because it offers a supportive softness. You can comfortably sink into the mattress without needing a search and rescue team to roll you out of bed in the morning.

CHOICE also reviewed the Koala mattress. While some memory foam mattresses can be too hot, the Koala is made with breathable Kloudcell foam. The open-cell design of this foam ensures air can move around during Aussie summers without compromising on the bounce factor. Even so, some reviewers on ProductReview.com.au still said it was a little too warm for them.  So, it may not be ideal if you live in Queensland or the Northern Territory.

Another upside of the Koala mattress is that, like the OneBed, it passes the wine glass test, minimizing disturbances. This makes it a little too easy to stay in bed if your co-sleeper gets up first in the morning. It also makes it easier to justify a glass of pinot with your Sunday arvo Netflix and chill. Our team member also reports that this memory foam mattress relieves pressure. Other reviewers on ProductReview.com.au say it alleviated back pain. Now all Koala needs to do is include a gap to accommodate your spooning arm, and it'll be a side sleepers' dream.

You're a side sleeper who needs more support.

Best for kids -> Ecosa

Ecosa mattress

We reckon the Ecosa mattress is the best mattress for kids for 3 reasons: it's breathable, has a waterproof cover, and a customizable firmness. Kids find it harder to cool down than adults do, so they can be impacted by the heat more. The Ecosa mattress has pincore holes so that air flows around the mattress. It's also made from G7 gel-infused foam, and ECO-Tex open-cell foam, both of which are more breathable than normal memory foam.

What we really love about the Ecosa mattress is its waterproof cover. Kids are more prone to spills and little accidents than adults, so the waterproof factor scores big points in our books. The cover also helps to protect from dust mites and bacteria. This gives the Ecosa another big tick for kids with allergies. We also rated the adjustable firmness of this mattress. As your child's height and weight changes over the life of the mattress, they may prefer a different firmness from one year to the next.

Aussies love the Ecosa mattress, scoring it just over 4 stars over nearly a 1,000 ProductReview.com.au reviews. Some said it relieved back and shoulder pain. We think this makes it a good mattress for kids because they tend to be more accident and injury-prone than adults. The cons? The Ecosa nearly scored a 3.5 in the value for money category, which wasn't as good as its counterparts. Some also said it took a little while to get used to their Ecosa mattress.

Best for back sleepers -> Ergoflex

Ergoflex bed in a box

Ergoflex is one of the pioneers of the original bed in a box mattresses. Unlike some of their competitors, they've been around longer than the 10-year warranty of their product. This mattress was designed in 2006 to compete with the world-standard TEMPUR mattress range. The Ergoflex 5G is our pick for back sleepers because it's made from high-density memory foam that relieves pressure. Back sleepers need a firmer, denser mattress to ensure proper spinal alignment. 

Ergoflex have years of experience making mattresses for 'sufferers of back pain, fibromyalgia, circulation problems or joint complaints.' CHOICE reviewed the Ergoflex, and it nearly scored 5 stars over almost 1,500 reviews on ProductReview.com.au. You can count all of its 1, 2 and 3 star reviews on one hand. The only major downside we can see is its cost - at $1,499 it's one of the priciest on our list. Even so, you're likely to pick it up for a few hundred dollars less in one of their sales.

Back sleepers on ProductReview.com.au reckon the Ergoflex was firm without being hard or uncomfortable. Several commented that it relieved back pain, with more than a few specifying it had helped with lower back pain. One reviewer said they even wake up happy before their morning coffee. The proof is in the pudding. With so many years under their belt, it's not surprising that Ergoflex has mastered the art of pressure relief.

Best hybrid -> Sleep Republic

Sleep Republic hybrid mattress

To say that Aussies love the Sleep Republic would be an understatement. After combing through review upon rave review, we reckon it's the democratic choice for best hybrid mattress. While some mattresses rely solely on pocket springs or memory foam, the Sleep Republic boasts cashmere, memory foam, and latex, as well as up to 2,250 pocket springs across 5 different body zones. In short, it combines the best parts of all the mattresses for the best of both worlds.

The Sleep Republic mattress is truly impressive. The top layer is a luxurious knitted cashmere, on top of a cooling gel-infused memory foam. Together, these provide softness and pressure relief while maintaining good airflow. Next is a layer of ventilated natural latex, which also regulates airflow, and provides firmness. Under this layer are its 2,000+ pocket springs, which form a supportive foundation fit for a queen or king. 

We love that Sleep Republic donate their returns to charities like Vinnies and the Salvation Army. Reviewers marveled at how Sleep Republic has packed so many layers into one box. This mattress provides a medium / firm feel, but some ProductReview.com.au reviewers felt it was too soft. The cashmere, foam and latex top-layers could be the reason for this. And hey - if you're not a fan, you have 100 nights to return it.

You want the best of both worlds in one mattress.

Best for hot sleepers -> Eva

Eva mattress and bed frame

The Eva mattress is a hybrid mattress designed to keep you cool all summer long. Like the Sleep Republic, it boasts the benefits of memory foam and latex mattresses, but offers heightened support (literally) with 5 zone pocket springs at the base. It's our pick for hot sleepers because it's made with breathable materials and a cooling top layer, but doesn't compromise on support. The first breathable gel-infused memory foam layer offers pressure relief, which is backed up by open-cell natural latex underneath.

Several Aussies on ProductReview.com.au said it kept them cool, which was unusual for a mattress with two kinds of memory foam inside. Among these reviewers were folks from Queensland, Sydney and Cairns, which is even more impressive given that their summers rival the infernos of hell. Eva reckons their mattress is a 7-8/10 in terms of firmness. At $900 for a queen, the Eva was also one of the cheapest mattresses on the list. This is why the Eva mattress gets full marks from us.

Important features to consider

All the mattresses we reviewed allowed you to return them if you weren't happy, and most offered free delivery, too. Here are some other things worth having a think about.

Pressure relief

Memory foam and latex mattresses are designed to absorb pressure better than a classic spring mattress while maintaining good support. If you have certain spots that require better pressure relief, it may be worth finding a customizable mattress to cater to this.

Breathability

Most mattresses are made up of several layers which are glued together. If these layers aren't breathable, you may end up feeling too hot. Moisture-wicking covers made from TENCEL or bamboo fabric can also help with breathability, as can wool or gel-infused mattress toppers.

Sleep position

As a general rule, back sleepers need a medium mattress to balance comfort with alignment, while front sleepers need the firmest mattress as their body weight is already cushioned by their stomach. Side sleepers should go for a softer mattress. This allows their pressure to sink deeper into the bed. 

Trial run

Most online mattresses offer a trial run, but some companies charge for pickup outside of metro areas. The reviews show that certain companies also make it difficult to return your mattress, so if you're a picky sleeper, check to see how easy it is to return your bed for a refund.

Transparency

It was sometimes difficult to figure out how mattresses were made, what they were made of, or where they were manufactured. Be wary of companies that make vague claims, as it could indicate that the product was not made ethically.

Versatility

A couple of the mattresses on our list have customizable firmness, including some with different firmnesses for each side of the bed. If your mattress doesn't have this option, you can also try a mattress topper for one side.

What you get if you spend more

The mattresses we picked range from around $700 to $1,600 for a queen-sized bed. Most were around the $1,000 mark, but this is what the pricier ones had to offer.

Trustworthiness

Two of the most expensive mattresses on our list are made by companies that have been around 10+ years. These companies have consistent 5-star reviews. We reckon mattresses made by longer-standing companies are more likely to do what they say on the box.

Customer service

Customers seemed to find it much easier to return mattresses they'd paid more for. Funny that.

Environmental friendliness

Mattresses that cost more are usually made with the environment in mind. Pricier brands are also more transparent about the exact makeup of their mattresses, while cheaper bed makers can be vague about the makeup of their product.

Fancy marketing

Not surprisingly, the most expensive mattresses had the most expensive-looking marketing. If you don't care about the finer details of your new bed, you can probably choose a cheaper mattress.

Frequently asked questions

What’s a mattress in a box?

Sometimes called a 'bed in a box,' you buy a mattress in a box directly from a manufacturer, instead of a retail store or showroom. By shrink-wrapping mattresses and shipping them in boxes, manufacturers like Sleeping Duck and Koala make buying a bed straightforward. When you buy a mattress online, it can be delivered as quickly and easily as an organic vege box or a Sephora splurge. While some boxed mattresses have pocket springs, most are made from memory foam or latex.

Cutting out the middleman means that mattress in a box companies can pass savings on to you.  When you buy a mattress online, you're not paying an in-store salesperson to hover around, or for bricks-and-mortar overheads. Shipping and handling costs are minimized, and the delivery fee is usually included in the mattress price. CHOICE reckons a mattress in a box can be just as comfy as a traditional mattress at 6x the price.

Should I buy a mattress online?

Buying a mattress online can be a real time and money saver. You don't need to bribe your mate with a slab of VB to borrow their ute, for starters, and there are no pushy salespeople. Delivery is usually much less painful, especially given that most sellers offer free shipping. The bad news is someone has to be there to sign for delivery, and you can't try before committing to buy. Fortunately, most sellers allow a 1-3 month trial period once you buy your new bed. 

Online mattress companies make bed-buying simpler by offering only 1 or 2 kinds of mattress. This makes buying a bed more painless, but limits your choices - especially if you're not a fan of memory foam. Even so, some mattresses are customizable, and sellers like Sleeping Duck offer different firmnesses on each side of the bed. All the beds we reviewed had a decent 10-15 year warranty, although traditional mattresses sometimes have longer warranties.

How easy is it to return a mattress in a box?

You can't always try before you buy, but you can buy and return. All online mattress sellers across our research offer a trial period. Most trial periods are between 3-4 months, and most brands require a 'minimum use period' to be sure you've given the mattress a fair go. Just like a pair of shoes, you can't return your mattress if it's in bad shape.  Most brands ask that you use a mattress protector to prevent damage during the trial period.

If it turns out that your new mattress isn't your cup of tea, there's usually no exchange fee. You may be asked to pay for pickup if you live in a rural area. Several of the sellers we reviewed donate their returns to charities like Vinnies or the Salvation Army, which we thought was pretty cool. Others recycled theirs into new products like carpet underlay. If you do decide to buy a mattress in a box, it's worth doing some research to be sure it won't end up as landfill. 

What type of mattress should I buy?

There are roughly 4 kinds of mattresses you can buy online: memory foam, latex, pocket spring, or hybrid.

Most online mattresses are made of memory foam. Memory foam was originally designed in the late 20th century to cushion astronauts' bodies during take-off and landing. It's a supportive material with a medium softness that moulds to your body, relieving pressure. Mattress sellers sometimes call it 'temperature-sensitive viscoelastic material' to sound fancy. Gel-infused memory foam is also common in Australia, as it's more breathable during hot summers.

Unlike a traditional mattress, there are no coils or springs in memory foam beds. This means your bed won't get squeaky over time when the metal begins to rust. On the other hand, memory foam absorbs more sweat over time, which is another reason why breathable gel-infused foam is ideal for our climate. If you're used to a traditional bed, you might find a memory foam bed takes a little getting used to, as it absorbs force instead of bouncing back like a spring mattress.

Perhaps you like the idea of memory foam, but want something firmer, or more natural. A latex foam mattress could be right up your alley. Natural latex comes from the sap of the rubber tree, which means it's biodegradable. Synthetic latex is made from petrochemicals, and feels less springy than natural latex. Synthetic latex can have a bit of a smell, and may get lumpy over time. Like memory foam, latex moulds to your body shape for support and pressure relief, but it's not temperature sensitive. This makes it firmer than memory foam.

Pocket spring mattresses are different from traditional coil mattresses. While coil mattresses are made from springs fixed together by wires, pocket spring mattresses fit thousands of springs into fabric pockets. These mattresses have better air circulation than memory foam mattresses, and offer good support with separate springs. Online pocket spring mattresses often divide their springs into zones to offer smarter weight distribution, so they can be a good choice if you're sharing a bed.

Hybrid mattresses are made from a combo of memory foam, latex, or pocket springs. For example, Sleep Republic and Eva mattresses both have pocket spring bases with layers of latex and memory foam on top. Hybrid mattresses like these can be a little pricier because of all the materials. At the same time, they offer the benefits of 2 or more materials combined. 

How firm should my mattress be?

Mattress firmness is a touchy subject. CHOICE reckons stomach sleepers should opt for a firm mattress so their spines are well-aligned. Most of the mattresses we reviewed are designed to be medium firm, which is ideal for back sleepers who need neck, back and spinal support. At the same time, a medium firmness allows back sleepers enough softness for comfort and pressure relief.

According to CHOICE, side sleepers should go for a softer mattress so they can sink in comfortably. The logic here is that your weight is concentrated on one side of your body, whereas stomach and back sleepers spread their weight out over a wider area. If your bed is too firm, or too soft, you can always balance it out with a mattress topper. 

How much should I spend on a mattress?

All the beds we reviewed in this guide cost between $700 - $1,700 for a queen-sized bed. Online mattresses are cheaper than those from bricks-and-mortar shops because there are no middlemen to take a cut. You can expect to spend around $1,000-$1,300 for a decent queen-sized mattress in a box, or between $1,400-$1,700 for a higher-end option. The 3 most expensive beds on our list were from the most experienced sellers. Reviews rated their customer service highly.

How long should a mattress last?

All the mattresses on our list have warranties of 10 years or more, but CHOICE reckons you should replace your mattress every 8 years. If your mattress is lumpy or sagging, you may need to replace it sooner. Repeatedly waking up sore could also be a sign that it's time for a new bed. Memory foam and latex mattresses absorb odours and spills more easily, and a mattress protector is a good idea regardless of the type of bed you own. If you take care of your mattress, it should last longer.

Flipping your mattress may also extend its life. Unlike the old days where you had to flip the whole thing, most online mattresses only need rotating. This is because the top and bottom layers are usually quite different. As a rough guide, pocket spring mattresses should be rotated every 3 months, and memory foam, hybrid and latex mattresses should be turned every 6. For more info, see your mattress manufacturer.
