The Best Quality Possible. Built to Last. Full transparency. Here's exactly what's inside.
Comfort Exactly how you want it
The BreatheTech hyper soft bamboo knitted cover together with specially manufactured Australian Made Antigravity Surface Foam ensures the ultimate softness without impeding sleeper moveability (compared to memory foam for example), and coolness.
Get the Firmness just the way you like it at home.
For both you and your partner, interchangeable firmness system that allows you to adjust it at home without pressure, to perfection.
Not just foam. Real Steel Springs for Proper Back and Body Support.
This mattress is setup to ensure the ultimate body support. A layer of adjustable variable firmness foams together with a perfectly calibrated twice tempered steel multizone pocket spring system ensures that the support is rock solid, and directed to the right parts of your body in just the right amount.
More Functional Space on the Bed thanks to Perimeter Springs
A Perimeter Zone of high strength Twice Tempered Steel Springs ensures that you can sleep right up to the edge, without collapsing it and rolling off (as often occurs with foam only mattresses which lack spring support). This provides up to 20 percent extra functional space on the top of the mattress, and makes ‘the Queen size mattress feel like a King’.
Refreshable Cover and Foams
so you can keep it like new.
Designed so you can keep it like new. The BreatheTech™ Cover is built and tested to resist pilling so you can Machine Wash it as often as you like - your can even replace it with a new one whenever you want.
Even all the 100% Australian made high density foams can be removed and vacuumed, or eventually replaced if you prefer. The high quality springs, which are built to last, mean this is possible even several years down the track.
A mattress that sags after a year or two of use can be seriously detrimental to your body
This is why the Mach II is built with Indestruct twice tempered steel springs to overcome the shortcomings of a foam only mattress. The two layers of foam that rest on top of the springs are 100% high density Australian-made AirGrown foams, which are incredibly sag-resistant. And just to be sure, we tested it with 8 years of simulated heavy usage.
There's no doubt about it. This mattress is built to last.

At Sleeping Duck, we have two initial firmness options which you can choose from! We believe the firmness of your mattress is a very personal thing. It can depend on a range of factors such as a person's activity, body shape, weight and medical history. While we're not medical professionals, as a general rule of thumb from speaking to thousands of our customers we have some general starting recommendations.
Recommended for side sleepers or front sleepers, our Medium sinks in slightly and contours to your body shape, allowing for targeted support. It's designed to relieve common pressure points such as shoulders and hips. You will wake up feeling cosy and well rested.
Recommended for back sleepers or for those with back problems our Firm has a strong focus on providing overall support, while still providing an initial softness through our AntiGravity layer.
Recommended for couple that can't agree! Available on our Queen or King size, Half-Half is ideal for couples who have different firmness preferences. This means one sleeper side will be Medium and the other sleeper side Firm.

Our mattresses are compressed, vacuum sealed, rolled, and finally boxed for convenient travel. By using vacuum compression technology, we can reduce our mattress to one fifth of its standard thickness. For example, our King size mattress comes packed in a box approximately 200cm x 40cm x 40cm.
The springs in our mattress move independently. This means with the right equipment they can be compressed and rolled up without compromising performance or durability.
Once decompressed, the mattress will return to its original size and shape within 72 hours. Without the right equipment, attempting to fold or roll up an opened mattress will result in potentially permanent damage to the springs.
Our Hybrid designed mattress is made up of four layers, each with their own cleaning recommendations.
Our BreatheTech cover can be laundered in a washing machine on a cold gentle cycle. We then recommend air drying the cover flat, out of direct sunlight (do not tumble-dry). If you find that the stains cannot be removed, or if it is damaged beyond repair, a new topper can be purchased separately.
Our AntiGravity cover, ComponentAdapt cover and Precision Foam Pad cover can be spot cleaned to remove spills or stains, or gently vacuumed using a handheld vacuum.
The Precision Foam Pads and the AntiGravity surface foam cannot be washed, and shouldn't be spot cleaned with anything wet. If they do get wet they should be patted dry or aired, out of direct sunlight, then vacuumed or brushed gently.
Please contact our team at SDHQ if you have any questions.
We've tested our mattress with electric blankets and can confirm that the heat won't affect the performance of our foams. That being said we always recommend exercising the appropriate caution that comes with operating an electric blanket.
A mattress protector can absolutely add that extra peace of mind and keep your mattress fresh for longer. If you do choose to use one, we recommend a breathable material such as TENCEL™ or bamboo. This will ensure the mattress continues to have the best air circulation for a cooler sleep.
Our BreatheTech sleep surface is washable, for those times where a mattress protector doesn't quite, well, protect. If washing doesn't quite get you the results you're looking for, you can always refresh your cover by purchasing a new one through SDHQ.
To exactly replicate the size of a King mattress, you would need to combine two Long Singles (not Singles).
A Long Single is the width of a Single mattress, with the length of a King mattress. If you were to use two Single mattresses, you'd find them much shorter than a King.
We do not make Long Single mattresses, however our King and Queen sizes allow Half-Half firmness configurations. This allows for each sleeper to customise the firmness of their side without having to compromise. Coupled with our AntiGravity foam and the multi-zoned pocket spring system, you shouldn't feel your partner move any more than two Long Singles together.
It's important to note that our 100 Night Guarantee only covers one return per household. If you decide to purchase two mattresses to place together, only one will be eligible for return.
For mattresses, bed bases, and frames, delivery options and times will vary depending on your area. You'll be advised of your delivery method during the checkout process, after providing your address.
