Full Sleeping Duck Mattress Review

The Sleeping Duck mattress is a new hybrid mattress only available in Australia and the UK.

What makes it special is the fact that it can be easily customized by moving the various layers around.

Not only can they be moved vertically, they can be arranged in any way to provide the perfect level of firmness for each partner and for each section of the body.

This also means that if with time you change your firmness preference, you won’t need to change the whole mattress. Quite clever.

What Type of Mattress is the Sleeping Duck?

The Sleeping Duck is a hybrid mattress that encompasses pocket springs, high density foam, memory foam, and natural latex.

It is good for those who sleep with a partner and/or have back and shoulder pain.

Initially the mattress is sold in a medium or firm firmness setting, however, it can be changed during the initial 100 night trial.

Each side of the mattress can have a different firmness to meet the preference of each sleeper in the bed.

It’s ability to solve sleep issues comes in the ability to customise the firmness of the mattress.

If for instance, you started with a firm choice, and you thought it was too firm during the initial phase of the trial, you can simply change it to the medium firmness by swapping a layer inside the mattress, and this is free of charge during their 100 night trial.

How Firm is the Sleeping Duck Mattress?

The Sleeping Duck mattress is available, initially, in two firmness levels:

  • Medium 5.5/10
  • Firm: 8/10

During the trial it can also be customised further to:

  • Soft: 4/10
  • Extra firm: 9.5/10

Changes to the mattress firmness are absolutely free during the 100 night trial period.

How Many Layers Does the Sleeping Duck Mattress have?

The mattress layers exposed (animation)In the UK the Sleeping Duck mattress has 4 layers which are as follows:

  • Natural Latex, 2 cm
  • Memory Foam, 2 cm
  • High Density Foam (Firmness controller), 6 cm
  • Pocket Springs, 20 cm

In Australia the Sleeping Duck mattress has 3 layers which are as follows:

  • Hyper-Adaptive™ Foam, 4 cm
  • High Density Foam (Firmness controller), 6 cm
  • Pocket Springs, 20 cm

The total height of the mattress is 31 cm (12.2”) and it weighs in at 48 kg for the Queen size (UK King).

Hyper-Adaptive™ foam is unique to the Sleeping Duck mattress and combines the pressure relieving property of memory foam with the buoyancy of latex.

Made in Australia, it is specially designed to enhance the feeling of weightlessness on the mattress.

It is produced via pressure expansion rather than any chemical, which further enables it to be 8x more open than latex and memory foam.

How is Motion Transfer with the Sleeping Duck Mattress?

Motion transfer occurs when a partner in a bed rolls around or gets in and out of the bed.

This is especially prevalent for shift-workers.

However, the use of individually pocketed springs coupled with high quality foams help to minimise motion.

This implies that the Sleeping Duck does an excellent job at isolating motion.

The individually pocketed springs ensure that the motion is not transferred laterally through the bed, which implies if your partner moves around, you will certainly not feel it.

Does it Sleep Hot?

Mattresses work very similar to insulation in the walls – the thicker the insulation the better job it does of stopping the temperature from escaping.

This implies that mattresses that just have foam will be the warmest as the heat your body creates won’t be able to escape through the mattress.

On the other hand, spring only mattresses will be the coolest.

The Sleeping Duck mattress, however, is a hybrid mattress so it is in-between the warmest foam only mattresses and the coolest spring only mattresses.

Does it Have any Smell?

GECA logoYes, there is an initial smell associated with the mattress, however, this usually dissipates within a few nights.

In addition to this, the Sleeping Duck mattress is GECA certified, which is an Australian certification against the use of harmful chemicals and VOC emissions.

Does it Need a Base?

The Sleeping Duck mattress is designed to work on any firm flat surface.

If using a slatted base, Sleeping Duck recommends that the distance between the slats must be less than 8 cm.

The reason for this is that the pocket springs need support in order to function correctly and any gaps wider than 8 cm will leave a significant number of springs unsupported, thereby affecting both the feel and longevity of the mattress.

What Type of Cover Does the Sleeping Duck Mattress Have?

the mattress cover in detail

The Sleeping Duck uses a natural bamboo cover, which is breathable, silky, and antimicrobial—a perfect fabric for the changing bedroom climate.

Bamboo is being used more and more by the health unconscious as it’s a fantastic natural fibre with a very low environmental impact.

Most modern brand are at least looking at ways to introduce it in their production where it might make sense.

Sleeping Duck Mattress Durability

The Sleeping Duck mattress is verified for use by 2x 140 kg individuals for up to 10 years.

The warranty will replace any failed parts of the entire mattress (at company’s discretion) if the overall mattress has sagged over 30 mm.

Since the mattress is modular, replacement parts can also be bought as you need for a fraction of the original mattress price.

This is ideal if after a few years, you want to make the mattress feel like brand new or if you even want to change the firmness.
