Purchase and delivery

The Sleeping Duck Mattress can be conveniently ordered online through the Sleeping Duck website. The mattress will be delivered to your door in a compact box, with larger sizes (e.g. queen and king) being noticeably heavy.

Sleeping Duck offers free delivery Australia-wide, and shipping times are fast. Please see delivery times in our Delivery information section further down.

Sleeping Duck offer a premium delivery service (for an additional fee) to select areas of Victoria, New South Wales, and Queensland. This service includes the delivery of your mattress to a room of your choice, mattress unpacking, and packaging removed. You can also have your old mattress removed (if you select the ‘mattress removal’ option at checkout).

Our box arrived in good condition, and the box’s handy transport wheels allow for easy manoeuvrability. As usual, we recommend having two people available to unpack a mattress in a box, but it is still possible with one person.

You can see this mattress in ‘real life’ in our video review here:

Once all packaging is removed, the Sleeping Duck Mattress should be ready to sleep on after a few hours. With that said, we always allow a mattress in a box to decompress for 24 hours before testing.

Aesthetically speaking, the Sleeping Duck Mattress makes a strong statement. It gives off a modern, edgy vibe and oozes sophistication. The ‘SD’ brand label and rubber logo tag give off a distinct sense of class.

Mattress construction

The Sleeping Duck Mattress is an innerspring mattress that includes a breathable cover, two comfort layers, and a strong spring system.

1. BreathTech Cover

The Sleeping Duck Mattress has a BreathTech cover that is made from bamboo fabric. This has been specially designed for breathability and comfort, and feels soft and durable.

This cover is also removable (and washable) and forms an important part of the customisation process.

2. Foam comfort layers

The BreathTech cover sits over an ‘AntiGravity Surface Foam’ that is made from high density AirGrown polyurethane foam.

The second layer of the comfort section is named the ‘ComponentAdapt Customisation’ layer. The layer controls the firmness of the mattress, and it is this layer that can be altered.

3. Motherboard Spring System

These comfort layers sit over a ‘multi-zoned’ pocket spring system called the Motherboard. This spring unit has tailored support zones to suit specific parts of your body and is made from twice tempered steel springs.

The Motherboard also has a reinforced perimeter support for enhanced edge firmness.

How does the customisation work?

As we mentioned earlier, the Sleeping Duck Mattress has an incredible level of customisation. This means that you can choose from a number of firmness options to suit you, and your partner. 

On your initial order, you can choose either a ‘firm’ or ‘medium’ feel.

Additionally (on your initial order), you have the option to order ‘half-half’ – firm on one side, and medium on the other. This half-half option only applies to super king, king, and queen sizes and is ideal for those couples who have different firmness preferences.

If you aren’t completely satisfied with your initial selection, you can request from Sleeping Duck (at no charge) additional foam layers to alter the firmness of your mattress.

It’s worth noting though that to claim your free additional foam layers, you must wait 3 weeks from the time of delivery, and it must be done within the 100 night trial period. The additional layers of foam can be soft, medium, firm, or extra firm, so there are several options to choose from.

Sleeping Duck takes this customisation to the next level, by allowing you to request different foam pieces for different sections of the body. This feature is best shown in our video review (above).

This degree of adjustability is revolutionary. Although there are many customisable mattress options on the market, it’s fair to say that the Sleeping Duck Mattress has the highest level of customisation of any mattress in Australia.

The Sleeping Duck Mattress has the highest level of customisation of any mattress in Australia.

This unique adjustability makes this product very suitable for those who experience back pain, or for those who suffer with a spinal condition.

Comfort and support

The medium version of the Sleeping Duck Mattress offers nice pressure relief with foamy yet responsive feel. It is a little softer than some other ‘medium’ versions that we have tested, but it still offers reasonable support.

This medium version should suit most side sleepers, but it may also accommodate back and stomach sleepers also. Understandably though, this suitability will vary between individuals.

We rated the medium version as a 5.5 / 10 on the firmness scale (where 10 is the firmest). Please note that our firmness ratings are just a guide and they do not necessarily relate to comfort.

Medium Version

Furthermore, our firmness ratings are assigned based on Bedbuyer’s testing process and these may differ from firmness ratings given by individual companies. Mattress firmness will also vary depending on the type of bed base used.

We tested the Sleeping Duck Mattress on the Chiropedic Bed Base which is a good quality bed base with rigid slats.

As you would expect, the firm version is firmer (than the medium option). It is still nicely balanced with comfort and support, and maintains body position well. We certainly didn’t detect any dipping or sinking.

This firm version should suit back most back sleepers, but should also accomodate side and stomach sleepers. We rated the firm version as a 7.5 / 10 on the firmness scale.

Firm Version

If neither the firm or medium options are to your liking, you do have the option to request ‘extra firm’ or ‘soft’ foam layers to adjust the mattress firmness, as we discussed above. The extra firm option is noticeably firm, and will generally suit back sleepers.

We rated the extra firm version as a 8.5 / 10 on the firmness scale. Again, please note that our firmness ratings are just a guide and they do not necessarily relate to comfort.

Extra-Firm Version

The soft version offers plenty of pressure relief, and feels foamy and spongy. Some users may experience a small degree of sinking. It will generally suit side sleepers and we rated this option as a 4.5 / 10 on the firmness scale.

Soft Version

Assuming that you select a firmness option suitable for your needs, the Sleeping Duck Mattress offers admirable back support. Its pocket spring system (the Motherboard) feels stable, robust, yet nicely responsive.

The level of partner disturbance on this mattress is minimal, but this may vary. A larger mattress (e.g. king size) will usually involve lower amounts of motion transfer. Partner disturbance will also depend on the size of the occupants of the bed.

All firmness options of the Sleeping Duck Mattress respond well to normal sleep movements, however the soft version is less responsive due to the thicker foam layers.

In any case, we rated the overall level of responsiveness on this mattress as ‘optimal’. In basic terms, this means that changing sleep positions (and intimate activities) shouldn’t be any trouble.

Please note that our responsiveness scales are just a guide and preferred responsiveness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.

The finer details

The overall level of quality and craftsmanship of the Sleeping Duck Mattress is excellent. Its outer cover feels durable, and the side handles are strongly attached.

The zip mechanism that removes the top cover is strong and the ComponentAdapt foam layers and pieces are easy to rearrange. With that said, it is much easier to swap foam layers with two people.

Edge support is firm thanks to Sleeping Duck’s reinforced perimeter support. As usual though, edge support does suffer slightly in the medium and soft firmness options.

You may notice a new product smell upon opening your new mattress, but this should dissipate within a few days. It’s worth noting that the foams used in this mattress are certified as non-toxic by GECA (Good Environmental Choice Australia).

What bed base should I use?

As with most mattresses, we recommend the Sleeping Duck Mattress to be used with a bed base with flat panel slats such as the Sleeping Duck Indestruct Bed.

A bed base with solid slats (ideally with slats no longer than 8 cm apart) such as the Chiropedic Bed Base would also be very suitable.

We would advise against using a bed base with flexible (posture) slats as this type of base may not provide adequate support. Ultimately, the use of an unsupportive mattress foundation may void the mattress warranty.

Sleeping Duck Indestruct Bed

Furthermore, we do not recommend the Sleeping Duck Mattress to be used with an adjustable (electric) bed base as this may also void the warranty. Here is our full list of mattresses that are compatible with an adjustable bed base.

It’s worth noting here that mattress firmness, performance, and durability will vary with different bed bases.

Trial period and warranty

As we have alluded to, the Sleeping Duck Mattress comes with a 100 night trial period, which is a typical trial period in the online mattress market. This means that you can return the mattress for a refund if you are not satisfied (conditions do apply).

As mentioned earlier, requests for firmness adjustments must be done within the 100 night trial period. Requests for firmness adjustments cannot be made in the first 3 weeks (from the time of delivery).

This mattress also comes with a 10 year warranty to cover any faulty materials or workmanship. This is also a typical warranty length of many of its online competitors.

Available sizes

The Sleeping Duck Mattress is available in 6 sizes (super king, king, queen, double, king single, and single size) so it should accommodate most sleeping arrangements.

Here are Australia’s standard bed (mattress) sizes in 2024.

Final verdict

The Sleeping Duck Mattress combines quality, sophistication, and a clever design. It has revolutionised the mattress industry in Australia and Sleeping Duck’s attention to detail must be commended.

Bedbuyer’s rating:  4.6 / 5
