Founded in 2014, the Sleeping Duck Mattress is one of the oldest and best mattress in box brands within Australia.

Since hatching 🐣 the company has expanded their product line. They now also sell bed frames, bedroom accessories and bundled products.

Today's focus is on one of the best mattresses in Australia, the Mach 2.

Sleeping Duck Mattress Owners

The two founders of the brand are engineers based in Melbourne:

Winston Wijeyeratne and Selvam Sinnappan.

Sleeping Duck Shark Tank

Yes, if you were wondering:

In July of 2017, the founders had previously entered the Australian TV show “Shark Tank” in which they looked to partner an experienced investor.

After negotiating back and forth, the founders received a deal of $500,000 from investor Steve Baxter, but they had decided to turn down the investment.

Sleeping Duck Mach 2 Vs Original

Compared to the original (Pro), the mattress's core layers remain quite similar, with noticeable changes made to how the mattress looks.

There have also been improvements to functionality, it's much easier to now swap foams in and out.

In terms of the layers, they have also received updates to their names:

  • The 'Bamboo Cover' is now called the 'BreatheTech' cover
  • The 'Hyper-Adaptive foam' is now called 'AntiGravity foam'
  • The changeable 'High-Density foam' or 'Firmness foam' is now called 'Precision Firmness Pads'
  • The 'Pocket Spring System' is now called the 'Motherboard'

The comfort and firmness of the mattress remain the same, meaning existing reviews are still valid for their new model.

Further Sleeping Duck Mattress Detail

Sleeping Duck now only sells one mattress, the Sleeping Duck Mach 2 mattress.

For those of you who are searching for a Sleeping Duck Pro or Titan mattress review, you’re also in the right place.

The mattress now only goes by the Mach 2 name.

Some history for you:

Previously, Sleeping Duck had two other mattress types, the Halo and the Odyssey.

Very Greek inspired names.

However, these mattress models have been retired since 2016.

Up until 2019 and 2020, the company also sold the Sleeping Duck Lite and Pro mattresses but they have since been discontinued.

Now, the company is purely focused on the Sleeping Duck Mach 2 mattress.

Let’s Jump Right Into It

As the Sleeping Duck Mattress is one of the most expensive memory foam mattress options in the market, we have also provided some price competitive alternatives just below for your comparison.

Without further ado ladies and gentle, let’s not ruffle your feathers and get right into the Sleeping Duck mattress review.

Sleeping Duck Mattress Sale

Sleeping Duck doesn’t really go on sale.

There was a $50 off sale that used to run from time to time (which isn’t that much of a savings), but have since stopped this promotion as well.

The company's focus on offering a high-end mattress is a reflection and their sales being far and few between.

Sleeping Duck Pro Mattress Features And Benefits

In this section we’re going to dive under the covers and review the Sleeping Duck Pro mattress in more detail.

Sleeping Duck Mattress Layers

The mattress comprises of 4 layers, from top to bottom:

BreatheTech Bamboo Cover

  • Designed for breathability
  • Contains anti-microbial properties that keeps the mattress fresh
  • Has a soft feel to it
  • Removable and machine washable

AntiGravity Foam (not customisable)

  • Provides pressure relief
  • A breathable ventilated layer
  • This layer cannot be altered

Note: The first foam layer doesn’t change across the medium and firm mattresses, only the layer beneath it does.

Sleeping Duck Mach II Layers

Precision Firmness Pads (customisable)

  • Controls the firmness of the mattress
  • Ability to customise this layer to your preferred firmness
  • GECA approved

Motherboard (Multi-Zoned Pocket Springs)

  • Provides support for your body
  • 5 Separate Zones: Gives you support across the heavier parts of your body (shoulders and hips). But less where you don’t need it
  • Supports zero partner disturbance

Zero Partner Disturbance

The construction of the mattress (5 zone pocket springs and mattress layers) reduce partner disturbance throughout the night.

There have been many positive reviews of the mattress that mention this feature.

Sleeping Duck Mattress Firmness

The company offers three different firmness options:

Medium Firmness


  • Recommended for side sleepers
  • Will sink slightly whilst you rest on it but will provide support
  • We gave it a firmness rating of 5.5/10
Firm Firmness


  • Has increased lower back support
  • Recommended for back sleepers
  • Will still sink but will provide a stronger level of support
  • We gave it a firmness rating of 7/10
Half Medium and Half Firm


  • Recommended for couples who prefer different firmness options
  • You can make one half of the mattress medium and the other firm

Note: This is not a different firmness option, it’s simply a change in firmness from one half of the bed to the other.

How Do You Know Which Half Is Which?

The foams have unique colours.

Unzip the mattress and look at the second foam layer:

  • The white coloured foam is medium firmness
  • The purple coloured foam is firm firmness

Half-Half Mattress Size Options

The Sleeping Duck half-half mattress is only available in mattress sizes queen and king.

Further Mattress Customisations

Beyond this, you have the option to modify the firmness level for each section of the bed.

Meaning, if you want a medium firmness for your shoulders and firm firmness for your lower back, you can.

In total:

There are 5 sections you can adjust the firmness of.

Mattress Section Customisation

Sleeping Duck Mattress For Back Pain

If you’re looking into the Sleeping Duck mattress and you’re currently suffering from back pain, the firm mattress level is recommended.

Customers have mentioned that after sleeping on the mattress for a period of time, they noticed a reduction in neck, shoulder, back and hip pain.

How long did it take for customers to notice less back pain after using the Sleeping Duck mattress?

Quite quickly, the most common timeframe is 1 - 2 weeks.

How To Change The Firmness Of The Sleeping Duck Mattress?

During the 100 night trial, you have the option to adjust the firmness of the mattress.

To do so:

Contact the Sleeping Duck team and they’ll send you out a new foam layer.

Keep in mind:

Once the trial has finished, you can no longer adjust the firmness.

Sleeping Duck Mattress Minimal Trial Period

It’s very important to keep in mind that the minimal trial period for the Sleeping Duck mattress is 21 days.

Why is this important to know?

You cannot adjust the firmness of your mattress or return it within the first 3 weeks.

Sleeping Duck has put this rule in place as they believe it can take up to 21 days for your body to adjust to their mattress. 

How Firm Is The Sleeping Duck Mattress And Is It Too Firm?

For the first few nights, the mattress may feel too firm, but most customers say that this feeling goes away after a few nights.

On the other hand:

Customers who have had the mattress for a few years mention that it starts to become too soft.

Sleeping Duck Mattress Edge Support

A feature of the mattress is that it comes with reinforced edges.

This will provide you with enough support for you to sleep to the edge of the mattress.

It also makes it easier to get out of in the morning.

Sleeping Duck Mattress Weight Limit

The weight limit of the Sleeping Duck mattress is 280 kg.

Or 2 people of up to 140 kg each.

Sleeping Duck Mattress Dimensions And Weight

What is the weight of the Sleeping Duck mattress and how big is it?

Besides the single mattress which has seen a 2kg weight reduction, the weight sizes compared to the original variant have all increased by 1-5 kg.

This varies from size to size, but overall, the mattress is quite heavy:





92cm X 188cm X 31cm

30 kg

King Single

107cm X 203cm X 31cm

36 kg


138cm X 188cm X 31cm

43 kg


153cm X 203cm X 31cm

52 kg


183cm X 203cm X 31cm

65 kg


The weight of the mattress makes it quite difficult to change the bedsheets and rotate.

Mattress Care Instructions

Mattress Rotation

Rotating the mattress once a month for the first 4-6 months is recommended.

From there on, rotation a few times a year will do.

Sleeping Duck Mattress Cleaning

The bamboo topper the mattress comes with is removable and can be spot cleaned.

Just keep in mind:

  • Use warm soapy water
  • Allow it to completely dry before putting it back on

If your topper gets in bad shape / is damaged, you can buy a new one from Sleeping Duck.

Environmentally Friendly

Our Sleeping Duck mattress review wouldn’t be complete without exploring the company’s environmental practises.

You’ll be happy to know that Sleeping Duck’s mattresses are Good Environmental Choice Australia (GECA) certified.

Their manufacturing process has met the rigorous standards of GECA.

Meaning they are taking measures to ensure their product has minimal impact on human health and the environment.

Things To Consider Before Buying A Sleeping Duck Mattress

100 Night Trial And Free Customisation

Sleeping Duck offers customers a 100 night trial.

If you’d like to return your mattress, you can do so within the trial period.

The 100 night trial commences on the date you receive your mattress.

If you aren’t sleeping like a duck within the first 21 days and want to adjust the firmness of your mattress, you can free of charge.

Just let Sleeping Duck know and they’ll arrange for the adjustment of your mattresses firmness.


You cannot request a firmness adjustment within the first 21 days.

Sleeping Duck Mattress Return

The mattress comes with a 100 night guarantee.

If you aren’t happy with the mattress and want to return it, you can do so free of charge during the trial period.

After the trial has ended, you cannot return the mattress.

You cannot return your mattress within the first 21 days.

Keep In Mind:

Only one mattress per household can be returned under the Sleep Duck mattress guarantee.

Sleeping Duck Mattress Warranty

If you experience any issues with your mattress after the 100 night trial, you’ll be covered by Sleeping Duck’s 10 year warranty.

 As like many other warranties, it doesn’t cover general wear and tear. However, there is one pretty important thing to keep in mind:

The warranty only covers mattresses which are on a firm flat surface, including slatted bases. If you have an adjustable or sprung base, this will void the warranty.

The warranty also doesn’t cover things including:

  • Damaged mattress handles
  • Damages caused by moving the mattress
  • Minor manufacturing issues (small tears within the mattress)

Important Consideration:

As the mattress is very heavy, you need to take extra caution not to cause any damage whilst changing sheets or rotating it.

Ecosa Mattress

Note: As mentioned above, the Sleeping Duck half-half option is not a change in firmness. It’s simply an option that splits the firmness option on each side of the bed.

With the Ecosa mattress, you can adjust the firmness of the mattress from home whenever you’d like to.

The Ecosa mattress also comes with a few additional features including it being waterproof.

When comparing the mattress within the same size range, the price difference is quite large:

  • Ecosa mattress price: $599 - $999
  • Sleeping Duck mattress price: $799 - $1,599

Here’s The Thing:

You could save between $200 - $600 depending on the mattress size you’re after.
