Sleeping Duck Mattress

An Australian mattress market might not be so diverse but it definitely has some worthy gems.

One of these gems is the Koala mattress.

Do not be fooled by its simple two-layer construction: this mattress packs some great features right under the cover.

And this Koala mattress review is aimed to tell you more about them and see if the bed will make the perfect pick for you. So, get cozy and read on!


The Sleeping Duck is encased into a soft bamboo cover with the white soft top and sturdier grey sides. The bamboo rayon fabric is a semi-natural material, which means the following:

  • It’s breathable. Bamboo fibres allow the air to circulate and can effectively cool you down and prevent night sweats.
  • It absorbs moisture. Bamboo fibres can soak in moisture without feeling uncomfortably wet, so if you live in a humid climate, you can still ensure that your sleep is cool and dry.
  • It’s durable. Bamboo rayon is built to withstand active use and frequent washes if needed, and it has potent anti-microbial properties, so you can enjoy the odour-free sleeping experience.

Plus, bamboo is considered a renewable material, which means that the fabric doesn’t harm our planet, too!

And a couple more things about the cover:

First, it’s removable and washing machine-friendly, so the mattress maintenance becomes even easier!

Also, the cover has convenient handles on the sides, so you can easily move or rotate your mattress if needed. The seams on the handles seem sturdy, which means they last longer.

“It’s advisable to rotate a hybrid mattress every 3 months (1) to prevent saggings and indentations and ensure a uniform surface that will support your back.”

Sleeping Duck


The next part of this Sleeping Duck mattress review is dedicated to what’s hidden under the cover. So, the mattress is composed of the three layers, and here’s a detailed look at each of them:

  • First layer: hyper-Adaptive foam. This is a proprietary foam used for cradling your body and removing any pressure points. It has an open-cell structure and the feel that resembles natural latex to some extent. This foam is also breathable and doesn’t rely on your body heat to feel comfortable.
  • Second layer: high-density polyfoam. This layer is responsible for mattress firmness, weight distribution, and spinal support. High density makes the foam more resilient and allows withstanding years of active use without sagging.
  • Base layer: 5-zone pocket springs. Pocket springs make the core of the Sleeping Duck. This construction is less bouncy than a solid spring unit but still ensures that you’ll get sturdy edges. Plus, the springs contribute to the overall breathability and prevent mould growth inside the mattress, which prolongs its lifespan.

The height of the Sleeping Duck is 31 cm, which makes it a good combo with the majority of bed foundations on the market.

Overall, the mattress seems sturdy and combines some quality locally-made materials, so you can expect great performance for years to come.


This is where things start to get more interesting.

So, the Sleeping Duck is available in two firmness levels: Medium and Firm, and can technically cover the needs of most users. The second layer is responsible for firmness, and the manufacturer marks it with a different colour for each feel: the Medium layer is beige, while the Firm layer is purple.

Why is it so important?

Well, because there’s also a Half & Half option for those who haven’t yet determined their firmness preferences, or for couples who love the different mattress feel!

In this configuration, the second layer is split in half with one side being Medium, and the other side being Firm. So you can just try each side and choose which one will work for you, or sleep on different sides if you’re a mixed sleeper.

Cool, right?

It gets even better:

The manufacturer states that they can customize the mattress for you even further, in case if you have chronic pain issues, for example. So if you look for a versatile mattress, consider giving the Sleeping Duck a try.

Edge Support

The next couple of parts of this Sleeping Duck mattress review will determine its basic performance. So, let’s start with edge support. 

Solid edges are essential for a mattress lifespan because they ensure the uniform surface and prevent premature sagging. Plus, if you love sleeping closer to the edge, you need sturdy support so that you won’t roll off the bed, and this is where the firm mattress edges come in handy.

Thankfully, the Sleeping Duck is a hybrid, so you can expect great edge support from it. The coils are sturdier than foams and can withstand larger weight even if you’re sitting on the edge.

Motion Transfer

Another crucial parameter for a good mattress is motion transfer or motion absorption. There’s nothing more annoying than constantly waking up when your partner decides to turn from their back to the side, so your mattress should prevent this from happening.

Typically, hybrid mattresses lose in this competition to foam beds, but the Sleeping Duck is slightly different. It has a thick foam cushion above the coil system that can block some impulses and make the mattress less responsive to your or your partner’s movements.

Also, in the pocketed coil system, the coils are sewn to a fabric base and aren’t interconnected, which additionally reduces the motion transfer and makes the mattress more comfortable to sleep on.

How It Feels for Different Types of Users

Now, this part of the Sleeping Duck mattress review will be more specific, as it aims to determine how the mattress will feel for different types of sleepers: 

  • Back sleepers. If you sleep on your back, you may benefit from a mattress with a medium to firm feel, and the Sleeping Duck can easily offer you that. It’s Medium option perfectly adjusts to your spinal curves and relieves pressure in the protruding parts, so you won’t get any pain.
  • Side sleepers. Side sleepers of average weight can also benefit from the Medium option, as it has a sufficiently thick cushion made of foam layers. This cushion can hug your hips and shoulders and prevent pain and soreness in these areas. Moreover, the Firm option will make a good pick for overweight sleepers because it can withstand larger weight while maintaining support.
  • Stomach sleepers. Sleeping on your stomach is considered the least beneficial position for spinal health. When you’re lying on your stomach, the lumbar curve of the spine flattens and this can cause morning stiffness and pain (2). Thankfully, the Sleeping Duck has a Firm option that can support your lumbar spine in this position and offer you pain-free sleep.

Overall, the Sleeping Duck easily matches most sleeping positions and ensures the sound sleep in each of them. And if you’re a mixed sleeper, you can choose a Half & Half configuration and enjoy.

Other Important Information

In this part of the review, you will learn about the remaining features that make the Sleeping Duck mattress unique.

So, let’s begin right away by answering some of the most common questions.

Does the Sleeping Duck Sleep Cool?

Yes. Most hybrid mattresses allow the air to freely circulate within their layers because of the coil system. This, in turn, helps the upper layers dissipate your body heat more effectively and ensure cool sleep even if you live in hot climates or are prone to hot flashes 

Is the Sleeping Duck Odour-Free?

Yes! The same coil core and improved air circulation does several great things. First, it wicks away excess moisture and inhibits the mould growth, so you won’t feel the funky odours. Second, the improved airflow also helps remove the initial foam odour if it was present after unpacking. So yes, you can count on odour-free sleep with the Sleeping Duck.

Is the Sleeping Duck Sex-Friendly?

Many people use their beds not only for sleeping but also for love activities.

And the Sleeping Duck thanks to its hybrid construction, makes a perfect sex-friendly mattress. It doesn’t sink in under your weight and offers some good bounce that can spice up the mood.


Sleep should be healthy because it’s the time when we heal and repair our bodies.

And you surely won’t get good shut-eye on a mattress filled with harsh chemicals. So the Sleeping Duck addresses this issue in the following ways:

  • By using sustainable and healthy foam-making technology, known as Pressure Foaming. This technology eliminates almost all harsh chemicals from the process, thus making the final product more neutral and hypoallergenic.
  • By cooperating with the Good Environmental Choice Australia (GECA).  The Sleeping Duck foams come with the GECA seal of approval which means that they meet the standards of manufacturing and don’t contain any harmful chemicals.


The company offers free delivery Australia-wide. The items are dispatched from the warehouses in Sydney and Melbourne within 1-2 business days. Depending on your location, you may wait from 5 to 14 business days

If you miss the delivery day, you can either contact the courier company via the card they leave you. Or, you can allow the courier to leave your order in the safe and dry area — such as a garage or veranda — if you do not think that you’ll be home on the delivery day.

Trial and Returns

The Sleeping Duck has a pretty straightforward trial and returns policy.

You can decide if the mattress fits your needs within 100 nights, and this period has certain conditions:

  • the first three weeks is an adjustment period, and you cannot file in for a return during this time;
  • if after three weeks you find out that the mattress isn’t right for you, you can order a firmness swap for free and adjust the feel of your mattress.
  • if after changing the firmness you don’t feel satisfied, you can file in for a return

Typically, the company covers all the expenses and offers you a 100% refund via the original payment method. But if you live in a remote area, you might be asked to donate a mattress to your local charity.
