Sleeping Duck is a mattress in a box company that is based in Australia and has won multiple awards, turned down shark tank investors, plus won Australia’s ‘Best Innovation’ Mattress in a Box for 2019. The quality of Sleeping Duck speaks volumes and matches its achievements. Lately, it’s gone through a significant rebrand and is now called SD Mach II with improved aesthetics, functionality, and a few layer name changes. However, what's excellent is the comfort of the mattress is unchanged, and now it’s more comfortable to interchange the foams, so you get a range of firmness levels. Existing reviews are still certainly valid for this new model.

"The best mattress I’ve ever slept on. I was nervous buying a mattress online. Sleeping Duck made it so easy.... if I wasn’t 100% happy they would provide a full refund. I had nothing to lose! I no longer wake with a sore neck or back. The mattress is firm and snuggly at the same time. The best night’s sleep ever. Thank you" Adrienne Hamann - Sleeping Duck Mattress Review

What's the SD Mach II mattress made from?

It's easy to see what makes Sleeping Duck unique. From the breathable bamboo cover to the combination of hyper-adaptive foam, high-density foam, and pocket springs for excellent support.

AntiGravity Foam - Acting as the top layer with open cells for breathable cooling effects. The comfort foam created by Sleeping Duck doesn't contain memory foam or latex, although acts like the best of both of the materials. Providing pressure relief, responsiveness, and breathability. And it's Australian made and GECA Certified.

Precision Firmness Pads - Is the supporting second layer underneath the comfort layer. This layer is the customisable layer where you can get the firm option and you'll be given a dense foam, and if you want a medium firmness, you can get the absorbent foam.

Motherboard - The bottom layer is the motherboard support layer which contains individually-wrapped springs (pocket springs). This layer makes partner disturbance minimal because of the independently acting springs that adjust to your body.

BreatheTech Cover - The soft, breathable bamboo cover has natural protection against microbes. The cover has an exciting stitching pattern and promotes cooling throughout the mattress.

Sleeping Duck Pillow - The pillow is made from the Hyper-Adaptive® foam like that mattress, so that means it’s 8x more open than standard latex and memory foam combinations. So the pillow allows airflow to pass through it, making sure your head stays cool at night.

Because the pillow is a mixture of memory foam and latex you get the best of both worlds. This combination means you'll feel the pressure relief of memory foam and the buoyancy of the latex, creating a sense of weightlessness whilst getting adequate support.

"Whilst I don't have any diagnosed back/neck issues I do experience some lower back pain and general soreness from time to time and since sleeping on this mattress have not experienced it at all. Extremely comfortable and supportive, I don't even notice when my partner rolls around as much. He too says it's the best! I am sleeping so much better, waking up actually feeling rested and ready for the day! - Tania M. - Sleeping Duck Mattress Review

Is the Sleeping Duck mattress right for you?

Australian made with a unique hybrid design makes the quality of Sleeping Duck mattress hard to match compared to other mattresses. If you’re a back sleeper, the firm option of the dense foam is perfect for you. For a side sleeper or if you prefer medium firmness ask for the absorbent foam. You can also request different foams after purchasing if you find your current setup not working for you.  As a bonus, if you and your partner prefer different levels of firmness just select half-half under the firmness option with any queen or king and you'll receive a Sleeping Duck Pro mattress set up with half medium and half firm inside.

Are Sleeping Duck mattresses good for back pain? Having this as your new mattress if you suffer from back, spinal, shoulder or hip pain would be a great choice because Sleeping Duck mattresses have an excellent quality of materials that are changeable to combat problem area and offer pressure relief. The mattress also has a solid base of springs that absorbs movements very well, offering minimal partner disturbance.

Sleeping Duck is a mattress in a box, making it easier to move around than a traditional mattress just make sure to put it in position before opening it up. When you buy it online you get free delivery Australia wide and orders from Melbourne are usually delivered on the next business day.

Overall, It’s more expensive than it's competitors in the mattress in a box industry if your looking for an affordable alternative check out the Noa mattress review or the Macoda mattress review. However, the Sleeping duck does have adjustable foam, great customer service, it's Australian made, as well as other factors we went over in this review making the price justifiable. Sleeping Duck is a highly recommended mattress and one of the most popular mattresses in Australia we have reviewed. If you want to try it out yourself you get a 100 night trial period, and if you’re not happy, you can send it back free of charge... But after sleeping on it you'll never want to leave the bed.
