- Select Your Items: Browse the Sleeping Duck website and add your desired mattress, bed base, or bedding to your shopping cart.
- Proceed to Checkout: Once you’re ready to purchase, navigate to your shopping cart.
- Enter Your Code: Look for the ‘Apply promotion code’ field, usually located under the ‘Order Summary’.

Tip: Some promotions are automatically applied at checkout and don’t require a specific code. If you’ve clicked on a deal link, the savings may already be factored into the price.
How we get the best Sleeping Duck Australia discount codes and deals
Here at Home Beautiful, we know creating the perfect bedroom is an investment. To help you make those upgrades, our dedicated Deals Team draw on industry expertise and trusted sources to curate this edit of Sleeping Duck discount codes and promotions. We then meticulously test each code on the Sleeping Duck Australia website to ensure it’s valid and read the terms and conditions to provide you with clear instructions on how to use the code or deal. Our commitment is to save you time and money by bringing you verified, up-to-date Sleeping Duck deals with all the important details, including expiration dates and any specific terms and conditions.
In the process, we’ve also discovered a few codes from the US Sleeping Duck site that don’t work on the Australian site. These include THANK, SLEEP600 and TAXDAY2026 – and I can personally confirm none work on the Australian site. So, if you’re looking for a valid working code for Sleeping Duck Australia, keep an eye on this page as we’ll list it here as soon as there is one.
Does Sleeping Duck have a discount code for first orders?
Currently, Sleeping Duck doesn’t offer a discount on your first order, but you can choose any of the deals here whether you’re a new customer or have shopped there before. You could also sign up to the mailing list to get details of promotions and sales as they are released.
Is there a Sleeping Duck promo code for the mattress?
Not at the moment but we’ll add it here if a code for the SD Mach II mattress does become available in Australia. It’s worth noting Sleeping Duck doesn’t typically offer a discount or promo code on an individual mattress – most promotions offer a discount on SD Sleep Systems (the mattress and Indestruct Bed base), or bundles that include a mattress and bed essentials such as pillows, sheets, duvet and mattress covers.
How much can I save with a Sleeping Duck discount code?
This depends on the promotion, discount code offer and products you choose but in most cases Sleeping Duck will highlight a maximum savings value in dollars (rather than a percentage).
For example, during Sleeping Duck’s EOFY sale in 2026, there was a discount code to save up to $784 off Sleep Systems, a code to save up to $269 off when buying more than one mattress and a promotional offer to save up to $300 on mattress and bed accessory bundles. But when I was reviewing these offers, I found savings values of different amounts based on the mattress, bed frame and essentials bundles I chose, including $384.80 off a Queen SD Mach II and Baker Indestruct Bed Sleep System and $329.80 off two Queen SD Mach II mattresses with the code. In this case, the discount worked out to around 10% off for both offers.
When does Sleeping Duck go on sale?
Sleeping Duck typically has key sales during EOFY, Black Friday and Boxing Day when you can save hundreds of dollars on Sleep Systems and other bundles or add-ons. For example, during the EOFY sale in 2026, you could save up to $784 off Sleep Systems (I found this discount on the Palais Super King Collete Midnight Super King Indestruct Bed and Super King SD Mach II mattress after applying the promo code).
More ways to save and get value with Sleeping Duck
Sleeping Duck offers several features and guarantees that add significant value to your purchase, even without a direct discount code:
- Free shipping and returns: Enjoy free standard delivery across the Sleeping Duck network in Australia. For those in eligible metro areas, you might even qualify for free premium delivery. If you decide to return your mattress or comfort items within the 100-night trial, the return shipping is also free.
- 100 Night Guarantee: Sleeping Duck offers a generous 100 night trial period for the mattress, as well as pillows, sheets and other essentials. This gives you time to sleep on the mattress and decide if it’s right – or return it for a refund.
- Free mattress adjustments: During the 100 night trial period, Sleeping Duck offers free firmness adjustments for the mattress. So if you find your initial medium or firm choice isn’t quite right, you can contact their team to arrange a swap of the internal comfort layers – including for soft or extra firm options – for each side of the bed.
- Free comfort layers: If you request different comfort layers during the trial, you can keep the other ones – which is great if your preferences ever change.
- Newsletter: While Sleeping Duck doesn’t currently have a discount code or offer for new subscribers, the newsletter does give you access to news on the latest promotions releases and other offers.

Sleeping Duck promo codes usually apply to packages or bundles – here’s my tip to help decide if a Sleep System is worth it
Sleeping Duck’s Sleep Systems include an SD Mach II mattress and Indestruct Bed – with a huge variety of finishes and styles for the bed. If you’re in need of a new bed base/frame as well as a mattress, getting a Sleep System offers great value (especially with a discount). It also means you’ll definitely meet all the requirements for the mattress warranty, which has detailed specifications for the type of bed base required.
Sleeping Duck also offers up to four free swatches of the bed finishes, which is a great way to see and feel them before choosing one. Here are some examples from my request:
Each swatch is a good size for checking the colour and style in a room, and material details are printed on the back of them. My only criticism is that it would help to include the bed styles each finish is available in, because it does vary depending on which of the 10 frame styles you choose. You can also customise your Indestruct Bed but the pricing varies for that.
Still, if you’re considering buying the Indestruct Bed and SD Mach II together, choosing the bed style (or styles), checking what finishes are available, then requesting free swatches can help you choose.
Sleeping Duck FAQs: Shipping, warranties and more
If you’re new to shopping online for a mattress and other bed essentials, it’s likely you’ll have a few questions. We did too – so we’ve researched Sleeping Duck to bring you answers to some of the most common questions.
How do Sleeping Duck deliveries work?
Sleeping Duck offers free delivery to locations across Australia and you can enter your postcode before ordering to check the details. You can also choose to have your mattress delivered and unpacked for an additional fee (it was $109 when I checked), with the option to choose a date and time for the delivery. Sleeping Duck also offers removal of your old mattress at an additional cost (also $109 when I checked).
How do returns work with Sleeping Duck?
Sleeping Duck has a 100 Night Guarantee so you can try their mattresses and other items (like pillows, sheet sets, and duvets). If it’s not the perfect fit, you can return it for a full refund within 100 days.
Here are the key details to keep in mind:
- You can return a maximum of two mattresses per household under this guarantee, so you may want to only try one before buying more
- Sleeping Duck requests that you try each firmness level for at least 21 nights before requesting a different firmness or a return
- You can keep all the Precision Pads (which adjust the firmness) after trying them – great if things change in the future or you’ve got a Mach II in a guest bedroom
- Other items that qualify for the trial include sheet sets, pillows, BeatheTech mattress covers and duvet
- The Indestruct Bed, including the Auto Sheet Refresh component, are not eligible for the 100 Night Guarantee
Does Sleeping Duck have a store?
Sleeping Duck is an online retailer with no brick-and-mortar stores in Australia. But there is a Sleeping Duck showroom at 8 Carlton Street, Prahran where you can test and find the right mattress firmness, view Indestruct Bed swatches, Sleeping Duck bedding and more. You can even book a free firmness testing appointment to try out the mattress and Precision Pads in the showroom. But anything you buy there will typically be delivered as it would be when shopping online.
How long is Sleeping Duck’s warranty?
Sleeping Duck offers a 10-year warranty on the SD Mach II mattress, a limited lifetime warranty on the Indestruct Bed’s Steel Core Support System and a 12-month warranty on most other items.
Who owns Sleeping Duck?
Sleeping Duck is an Australian startup, founded in Melbourne in 2014 by engineers Winston Wijeyeratne and Selvam Sinnappan. After becoming one of the fastest-growing startups in Australia, Sleeping Duck expanded to the US, with a warehouse in San Diego, and now has over 60 employees (and counting).
“I’ve been so impressed by the quality of the SD MACH II mattress, both in the design and how it’s holding up – it still feels exactly the same as Day One.”
Rachel Weisz, Home Beautiful Shopping Writer
Sleeping Duck beds are customisable from the base to each side of the mattress – is it worth it?
Sleeping Duck is an Australian brand with a global following and plenty of awards to match – including a Good Design Award for the Indestruct Bed and Canstar Blue and ProductReview awards for the SD Mach II Mattress. It’s often a benchmark for people who are shopping for a new mattress, bed frame or both.
But I’ve also noticed Sleeping Duck has fewer sales and promotions than some other popular bed brands. Which makes the question “is it worth it” even more important to consider.
For Home Beautiful Shopping Writer Rachel Weisz, the answer is a solid “yes”.
“I love my Sleeping Duck MACH II mattress, which I got around the middle of 2025,” she tells me.
“The independent layers make it easy to adjust the firmness on one or both sides of the bed. During the 100-night trial, my partner and I actually realised we prefer different levels of firmness. I started with the firm and switched to the medium, while my partner opted to stay with the firm layer after trying both.”
“It’s made a big difference for the quality of sleep and I no longer wake up feeling stiff.”
Rachel Weisz, Home Beautiful Shopping Writer on her SD Mach II mattress
In the past year, I’ve slept on over 16 beds (and counting) for both work and family trips – from hybrid mattresses to spring/coil, foam, pure latex and even a traditional futon. This has given me a greater appreciation for the value in finding the right firmness – and the innovative way Sleeping Duck addresses this with the SD Mach II customisations.
But a new mattress and/or bed comes at a cost – and a Sleeping Duck discount code, promo or sale can make a big difference. So we regularly update this guide with the latest active offers in Australia to make sure you get a great price.
