Sleeping Duck


Unique Half-Half Firmness Option



Very Good

Sleeping Duck Mattress

  • Good 5 Zone Support System
  • Customisable Firmness
  • Half-Half Firmness Option

Thrust into the limelight during an episode of Shark Tank and Choice recommended in 2018, the Sleeping Duck mattress with its half and half firmness option has proven itself a worthy contender for Australia’s top Mattress in a Box. However these benefits come at a hefty cost, is the Sleeping Duck mattress worth its price tag?

Read Sleeping Duck Mattress Review


The Emma and Sleeping Duck mattress both offer comfort and great support in the form of a multi-zonal firmness build that assures that the necessary counter-pressure is provided in the appropriate areas. However this is taken a notch higher in the Emma mattress with its 7 zones compared to Sleeping Duck’s 5. In terms of breathability, both performed well to allow for a good level of heat dissipation.

Something to note about the Sleeping Duck mattress though is that it took up to 3 days to expand to its full size compared to the Emma mattress which was ready to be slept on the same day. Another major factor to consider is that the Sleeping Duck mattress is considerably HEAVIER than the Emma. A King-size Sleeping Duck weighs 60 kg and is not easily managed by a single person. So for those with pre-existing back/shoulder/muscular conditions it might be prudent to consider the ergonomics of handling the mattress as well as its actual performance.

The Sleeping Duck mattress is assembled in China from Australian-made foam. Unlike Ecosa, firmness adjustments are made by requesting a new foam topper of the desired firmness to replace the current one with as long as it is within the 100 night trial. Although this might be possible as well for Emma customers upon request. Ultimately, if you sleep with a partner with vastly different firmness preferences than yourself, the half-half firmness option could make the deciding vote for the Sleeping Duck.

However, if you have any intention of purchasing more than one mattress in the same household than Emma is the better choice as the 100 night trial applies for all purchases made, not just the first one. So people of differing preferences within the same household can take advantage of the 100 night trial as well which is great!

In terms of the benefits that each one has to offer, the value provided by the Emma cannot be argued with (especially during a sale). If the half and half firmness option is not of major importance to you, then the Emma is the clear choice considering the $700 price difference. With the 100 night trial, there’s little reason not to give the Emma mattress a shot before opting for an alternative.
