Design & Construction

Sleeping Duck vs Koala Mattress: A Closer Look at Their Construction

Sleeping Duck Mattress:

The mattress measures 31 cm tall, which is significantly more than many other mattresses in boxes you may be considering. The components of the Sleeping Duck Mattress are broken down in depth below:

Cover made of bamboo (1 cm thick)

  • It’s breathable
  • Comfortable to the touch
  • Antimicrobial by nature

Sleeping Duck Mattress is one of the few firms that uses bamboo in their cover, and I think it’s a significant plus. It will feel more luxurious than the typical polyester blends, which lack antibacterial characteristics. However, because the Tencel used in Koala Mattress has identical qualities, there is no distinct advantage.

Foam layer with Hyper-AdaptiveTM Technology (4 cm thick)
  • Combines memory foam’s pressure-relieving properties with latex’s buoyancy.
  • Designed in Australia

This is the white foam comfort layer in the image above. It’s made for optimal pressure relief and quick bodyweight response so you don’t sink too far into the mattress. It sounds a lot like the Kloudcell foam that you’ll find inside a Koala mattress.

High-Density Foam layer that can be customized (6 cm thick)
  • The stiffness is controlled by high-density polyurethane foam; you can choose between mild and firm.
  • GECA mark of approval (this is an environmental accreditation that simply says it passed testing to prove it’s beneficial for both the environment and you; learn more about GECA here).
  • This foam appears purple in the image above; however, Sleeping Duck’s dyes have just changed, and the medium is now light grey and the firm is now dark grey.

It’s a greater density foam than the Hyper-Adaptive foam above, so it has a firmer feel. If you leave it in the middle of the mattress (as I demonstrate above), it’ll work as a transition layer between the pleasant Hyper-Adaptive foam and the pocket coils below.

Pocket Springs with 5 Zones (20 cm thick)
  • 5 zones of support to provide focused assistance to your body
  • Pocket coils move independently of one another to reduce partner disruption and improve support.
  • Elasticized edges

The Sleeping Duck’s zoning is a feature that in-store brands frequently keep as an up-sell for luxury mattress models, so it’s great to see it here in a more affordable great mattress in a box.

Koala Mattress:

The mattress is 23 cm tall, which is slightly shorter than conventional all-foam mattresses, which are normally 25 to 27 cm tall. Sleeping Duck Mattress, which has more foam and some extra height from the springs, is 8 cm shorter than Koala Mattress.

  • Cover: The cover has a white top and blue sides, as you can see. Tencel Lyocell, a plant-based fibre known for its softness, breathability, and durability, is used to make the white top. Tencel is derived from Eucalyptus trees and is used by Koala Mattress.
  • Foam 1: Kloudcell foam, 6 cm Kloudcell is the Koala mattress’s comfort layer. It’s a Koala-exclusive patented foam. It’s not memory foam or latex foam; instead, it’s been designed to combine the greatest qualities of each. It’s a breathable, slightly bouncy, and pressure-relieving open-cell foam.
  • Foam 2: For the base, use 17 cm of high-density polyfoam. This is very normal, and it provides a solid base for the Kloudcell to work on.

Many other mattresses inboxes have three to four layers, whereas Koala Mattress only has two. The 6 cm of Kloudcell foam, on the other hand, is generous, and it’s a wonderful foam. Hugo is another alternative if you prefer a taller all-foam mattress made in Australia.

Type of construction

Each Koala is made up of two layers of sophisticated foam. Kloudcell open-cell foam as a foundation layer, and Eco foam as a top layer.

Kloudcell’s high-grade foam allows Koala mattresses to breathe and dissipates any extra heat through channels, ensuring that you are never overheated, even on the hottest Australian summer night.

Our plush memory foam bounces back so you don’t sink in like other types of memory foam, and it’s the perfect firmness, neither too firm nor too soft.

Don’t worry about flipping your mattress or adjusting the firmness level; Koala mattress is designed to fit practically any sleeper, so all you have to do now is redecorate your room and get matching bed sheets.

Like the other 20,000+ delighted Australians who believe Koala is the best mattress in Australia, you’ll wake up totally rested every morning.

The amount of weight

The lightest queen size mattress in a box on the market is ours. It’s half the weight of a Sleeping Duck mattress, at only 23kg. This allows anyone to easily set up and move the mattress around without assistance.

Mattress cover that can be washed

Because we want a mattress to last a lifetime, we included a removable and washable mattress cover that is simple to maintain clean and fresh. Simply unzip it and wash it in cold water when needed.

Probationary period

Our clients are extremely pleased with their Koala mattress purchases, as evidenced by user reviews. But, just to be sure, we gave them 120 nights to test our mattress before requiring them to affirm their decision. That’s 20 nights more than a Sleeping Duck mattress and 4 months of fantastic sleep.


Nobody like waiting for excellent goods to arrive, which is why we created Gumleaf, an intelligent system that provides Australia’s fastest delivery service. Order a Koala mattress online and have it delivered to your house in just four hours.

Time to set up

We made sure that our mattresses were simple to assemble, even if you didn’t have any help. All you have to do when our mattress in a box arrives is unpack it, unroll it, and wait 4 seconds.

Firmness & Feel

Sleeping Duck


As previously said, the Sleeping Duck mattress has a unique spring and foam construction that caters to consumers who seek the best of both worlds. One of the best features of this mattress is that it allows users to select their ideal firmness level. To begin, choose a Sleeping Duck mattress with a medium to firm texture. According to a Sleeping Duck pro mattress review, you may contact the staff and request a new, softer layer throughout the trial time if you wish to vary things up.

Most individuals will find this mattress to be comfortable to sleep on because it is very adjustable. However, we feel that some individuals may not enjoy it as much as we do. The Sleeping Duck Mattress, for example, maybe excessively firm for stomach sleepers, since it places somewhat greater pressure on certain sensitive body areas.

Furthermore, smaller sleepers may prefer a softer mattress than the medium-firm choice.

On the plus side, according to Sleeping Duck mattress reviews in Australia, most side sleepers will enjoy the medium-firm mattress’s hardness, which gives ideal support for the hips and shoulders as well as a full-body embrace. We recommend upgrading to the firmer choice if you are a heavy sleeper who has trouble sinking too far.

Because of the amazing support and pressure point relief provided by the Sleeping Duck, we recommend it for back sleepers and those with back discomfort. The foundation springs, high-density foam, and the unique Hyper Adaptive foam work together to support the sleeper’s lumbar and neck areas.


According to customer evaluations of the Sleeping Duck mattress, there will be some sinkage with this bed, but nothing too severe. The superb edge support and spring base, according to most customers, make it simple to roll out of bed in the morning. Although this is not a springy mattress, it does have some bounce thanks to the Hyper-Adaptive layer discussed earlier. As a result, the Sleeping Duck Mattress will provide you with greater support than a traditional memory foam mattress.

Overall, if you want a mild sinking sensation, this mattress is ideal. You’ll feel as though you’re floating above the clouds! If not, a bouncy bed could be more suitable. For a different option, read our evaluation of the Noa mattress.


Overall, Sleeping Duck mattress reviews indicate that this is a reasonably supportive bed. It is appropriate for both light and heavy sleepers, as well as those who like to sleep on their backs or sides. It’s also one of the finest alternatives for people who have chronic back pain, because the layers’ mix of materials adds to the comfort and pressure point alleviation.

Neutrality of temperature

The weather in Australia may be unpredictable at times, especially during the summer. As a result, it’s critical to invest in a mattress that keeps you cool and dry at night.

Fortunately, each layer of the Sleeping Duck mattress contributes to the mattress’s overall coolness and breathability. We looked at a Sleeping Duck mattress review option and found that it is a popular choice among Australians. When it comes to temperature neutrality, this mattress will outperform any all-foam bed, thanks to its pocket springs and naturally permeable bamboo cover.

Support on the Outside

If you’re searching for a mattress that won’t sag, Sleeping Duck is the way to go. This luxurious mattress has excellent edge support, so you won’t have to worry about rolling out of bed in the middle of the night or sinking when sitting on the edge. The borders of the pocket spring layer are strengthened with heavy-gauge coil springs, according to Sleeping Duck mattress reviews. Our final judgement is that this mattress is both comfy and durable.

Transfer of Motion

If your spouse wakes up in the middle of the night, the Sleeping Duck mattress performs an excellent job of isolating movement, so you won’t be disturbed. Overall, we feel this mattress is appropriate for couples as well as those who share their beds with children or pets.



Every evaluation of the Koala mattress emphasises the mattress’s excellent firmness. The Koala mattress is a perfect 6.1 in firmness (on a scale of 1–10, with 10 being firmest). It’s not too soft, but it’s also not too firm.

This hardness level makes it ideal for various sleeping positions, including back, stomach, side, and combination.

There is, however, one exception. For heavy sleepers, the Koala mattress isn’t the greatest option. People who weigh more than 105 kg may find the mattress excessively hard, since their weight may overwhelm the Kloudcell layer’s bounce and softness.

On the other hand, several Koala mattress reviews report that the mattress was originally firm, but that it softened after a week or two.

Even so, the majority of sleepers should be able to obtain a decent night’s sleep on this mattress.


This mattress is made up of a combination of memory and latex foams, as we mentioned in our Koala mattress review. It offers the bounce and responsiveness of a latex mattress with the pressure relief and motion isolation of a memory foam mattress.

These characteristics translate to little sinkage, so you’ll feel like you’re resting atop the mattress rather than sinking into it.


There isn’t a single complaint about the general support provided by the Koala mattress. This mattress will provide full support to your body regardless of your sleeping position.

Back and stomach sleepers will benefit from the firmer Ecofoam layer, which aligns the spine and hips, avoiding pains and stiffness. Similarly, for side sleepers, the softer Kloudcell foam layer provides ample sinkage to relieve strain on their shoulders and spine.

Both layers complement each other well to keep combination sleepers comfortable in any sleeping position. This combination is particularly ideal for couples who sleep in various positions and have a hard time compromising on a mattress, according to the average Koala king mattress review.

Neutrality of temperature

All-foam mattresses are infamous for sleeping hot and not offering enough ventilation, but latex mattresses with inherent cooling qualities are preferred by hot sleepers.

The Koala mattress, on the other hand, maybe ideal for both hot and chilly sleepers. The Koala does not retain heat because of its open-cell design, which enables air to circulate, and its Tencel cover, which wicks away moisture.

Because a few Koala mattress reviews say that the mattress retains some heat, we wouldn’t recommend it to people who sleep hot. However, because it is fairly neutral, it may be the best option for couples who are unable to agree on a particular mattress temperature.

Support on the Outside

When sharing a bed with a spouse or sleeping near the edge, edge support is essential. We’re pleased to inform that our Koala bed evaluation found excellent edge support! (With one exception.)

When you first lie down, you may feel as if you are sinking, which may be confusing. After a few seconds, though, the mattress flattens evenly under you and increases its edge support.

Transfer of Motion

When sharing a bed, another important factor to consider is the mattress’s (in)ability to transmit motion and disrupt your sleep. If you’re a light sleeper or have a fidgety and restless spouse, you’ll appreciate the Koala’s ability to keep motion to a minimum.

Because the foam layers absorb motion, you may toss and turn as much as you like while still getting your Z’s.

Other Factors to Consider

Factors to Consider:

Our Koala mattress in a box is lighter, less expensive, and arrives in 4 hours. But the enchantment doesn’t end there. Take a look at our full comparison below to see if Koala Mattress or Sleeping Duck Mattress is the better choice.


When we started Koala Mattress, we wanted to make good sleep accessible to everyone, and affordability is a key part of it. Our modern Koala Mattress was designed to be Australia’s best mattress, but it’s still one of the most economical on the market, and it’s less expensive than a Sleeping Duck Mattress.

Zero Disturbance®

Pocket Springs mattresses carry movement from one side of the bed to the other, as anybody who has shared a bed with a restless sleeper knows. 

With Koala’s memory foam technology, that’s not the case. Our mattresses include Zero Disturbance® technology, which isolates movement from one sleeping partner distrubance from the other. And we do it with a single double mattress rather than two single beds on a double bed frame.


We believe that instead of a large number of low-quality objects, our homes should be filled with fewer high-quality objects. This is why our mattresses are built to endure a decade. It is beneficial to both you and the environment. A 10-year warranty is included with every Koala mattress.

That concludes our definitive Koala mattress review for the year 2021. Would we suggest the Koala mattress after considering everything? This is not a product for everyday usage. We wouldn’t recommend the mattress as a daily sleeping surface because we can’t guarantee it will endure much longer than 6 to 12 months. On the other hand, the Koala mattress would be worth considering if you have a guest room.

Customers who have used their Koala mattress for a short period of time tend to prefer sleeping on it, so if you have guests who sleep over a few times a year, the Koala mattress may be a nice option. To put things in perspective, here’s some fast math:

If the Koala mattress had a 6-month lifespan and your guests stayed for two weeks every year, the mattress would last more than ten years.

Frequently Asked Questions

Is it true that Sleeping Duck mattresses are any good?

Yes, Sleeping Duck is a luxury, long-lasting hybrid mattress made from the finest materials available. If you sleep on your back or side, or prefer medium-firm to firm mattresses, this is the ideal option for you. To discover more, read our entire review.

Which is the superior mattress, the Koala or the Sleeping Duck?

The Koala mattress and the Sleeping Duck mattress are quite different from one other, according to the various customer evaluations we analysed and our testing. As a result, it all boils down to what you want in a mattress. If you don't like conventional pocket springs, for example, Koala is a better option. Koala comes with the latest Kloudcell technology, which some customers may prefer. Both the Koala and the Sleeping Duck, on the other hand, provide customers with an almost identical sleeping experience. So, which is better, the Sleeping Duck or the Koala? You make the final decision

Is it possible to flip a Sleeping Duck mattress?

Sleeping Duck advises turning the mattress once a month for the first 4–6 months, as we stated in our review. After the first phase, merely flipping the mattress a couple of times each year is advised.

Is it possible to flip a Koala mattress?

No, the Koala should not be flipped. The sequence of the layers would be disrupted if you flipped the Koala mattress, as we stated in our review. This would either damage the soft layer or make sleeping on the hard layer exceedingly unpleasant. Twice a year, rotate it 180 degrees.
