Why we love the Sleeping Duck mattress:

The Sleeping Duck Mattress is one of the most well-known and universally loved mattresses in Australia. While on the pricier side, the extra dollars you spend are well worth it thanks to this mattress’s incredible level of customisation – with the Sleeping Duck mattress, you truly can make a mattress that suits your needs (and even the needs of your sleeping partner). This review is based on the latest Sleeping Duck model released in November 2020 – Sleeping Duck Mach II Mattress

Answer a few quick questions to get matched with the perfect mattress in Australia.

Is the Sleeping Duck mattress good?

Look at any online reviews of the Sleeping Duck mattress and you’ll quickly come to realise it’s one of the most popular mattress in a box products in Australia. While it wouldn’t be classified as a budget mattress by any means, it certainly makes up for the bigger price tag in features, comfort and customisation. 

Featuring a customisable, modular foam layer that can adjusted in 12 separate areas (6 on each side of the bed), the Sleeping Duck mattress goes above and beyond in its customisation capabilities – from whether you want a medium or firm overall, with a soft, medium or extra-firm micro-setting. What’s even better is that you can have a different level of firmness to your sleeping partner, which is a truly unique feature of the Sleeping Duck. Ideal for front, side, back or combo sleepers, there’s not much not to love about the Sleeping Duck. 

How does the Sleeping Duck mattress feel?


The Sleeping Duck comes in two initial firmness options: medium, firm and half-half. Medium is recommended for side sleepers or front sleepers, while firm is recommended for back sleepers or for those with back problems. Half and half is for couples with different firmness needs. SD also offers soft and extra firm options which are custom made Precision Foam Pads available after purchase.


Thanks to its AntiGravity Surface Foam layer, the Sleeping Duck mattress offers excellent pressure relief with superior comfort and cushioning. With Variable Pressure Foaming, Sleeping Duck has created a mattress that adjusts to the microcellular structure of foam, giving the mattress a softness and moveability that gently cradles the body.


As with most hybrid mattresses, the SD offers great temperature relief throughout the night thanks to its BreatheTech cover made from naturally-cooling bamboo. Meanwhile, the pocket springs allow for sufficient airflow resulting in a cool and comfortable sleep.

What does it cost?

Construction of the Sleeping Duck mattress

The Sleeping Duck Mattress starts with a ‘BreathTech’ cover made from bamboo fabric, which has been specially designed for breathability and comfort. This cover is also removable (and washable) and is an important part of the SD mattress customisation process.

The BreathTech cover sits over an AntiGravity Surface Foam and ComponentAdapt Customisation layer underneath. The ComponentAdapt layer controls the firmness of this mattress, which is the layer that can be altered to suit your firmness preferences. 

These two comfort layers sit over a ‘multi-zoned’ pocket spring system (dubbed the ‘Motherboard’), which can accommodate people of body shapes and sizes.

How much weight can it hold?

The Sleeping Duck mattress can take a total weight of 280kg, or 140kg per person. So while it should suit most people, for those who are heavier or have a combined partner weight of more than 280kg, it might not be the best mattress for you. 

Sleeper type

side sleeper

Side sleepers with an average weight will find the SD medium option the most comfortable with its thick cushion foam layers, which will hug your hips and shoulders and prevent pain and soreness.

back sleeper

For back sleepers, you’ll want to buy the firm version of the SD. It’s recommended for back sleepers or for those with back problems. The firm mattress has a strong focus on providing overall support, while still providing an initial softness through the AntiGravity layer.

front sleeper

Front sleepers will also enjoy the SD firm option to support your lumbar spine and offer you a pain-free sleep.

Is it good for couples?

The SD mattress is great for couples, especially as you can customise each half of the bed to suit the sleeper’s unique needs. It does have a weight limit of 280kg, however, so heavier couples might opt for a mattress that has a better capacity to hold heavier loads. 

Edge support

The Sleeping Duck is a hybrid mattress with solid edges, meaning you can expect great support from this mattress. The coils are stronger than foam and can withstand heavier weight, even if you’re sitting on the edge. 

Motion isolation

While hybrid mattresses typically are not as good at preventing motion isolation as traditional foam mattresses, the Sleeping Duck is somewhat different. With a thick foam cushion above the coil system, it blocks some movement and makes the mattress less responsive to motion in the bed. Meanwhile, its coils in the pocketed coil system aren’t interconnected, which actually reduces motion transfer and makes the mattress more comfortable overall.

Special features 

Sleeping Duck Mattress Customisation 

The Sleeping Duck Mattress has an incredible level of customisation, allowing you to choose the exact firmness level of the mattress that suits you (and your partner). When you first place an order, you choose either the ‘firm’ or ‘medium’ option. Also, on the initial order you can choose half-half (firm one side, medium on the other).

If after 21 days you aren’t completely happy with your initial selection, you can request from Sleeping Duck (at no charge) additional foam pieces to alter the firmness of your mattress. The additional pieces of foam can be soft, medium, firm, or extra firm. 

30 sleeps with the SD Mach II

As a hybrid mattress fan, I have to say the Sleeping Duck mattress really is a game-changer. I wasn’t totally satisfied with the medium level of firmness (although comfy, I prefer a super soft mattress). So, I decided to order additional soft foam pieces after 21 nights to really make my side of the mattress as soft as possible. It definitely made a difference in comfort and I found I nodded off a lot faster. Meanwhile, my partner prefers a firm mattress, so he kept it in its original state and had no complaints after 30 nights (and probably slept better than he has in a while). 

Sleeping Duck comparisons 

How does the Sleeping Duck mattress sit in the market? Well, it’s pretty unique, especially with its ultra-customisable features. Its biggest competitor would be the Eva, which I would recommend if you’re after a slightly less expensive mattress. However, if you want a mattress that really caters to your individual firmness needs, you can’t go past the Sleeping Duck.
