How Home Beautiful finds 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 an 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.
Recently, we’ve discovered a few codes from the US Sleeping Duck site that don’t work on the Australian site – these include THANK, SLEEP600 and TAXDAY2026. So, if you’re looking for a valid working code for the Australian site, keep an eye on this page as we’ll list it here as soon as there is one.
How to apply your Sleeping Duck promo code
Applying a Sleeping Duck discount code is straightforward:
- 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’.
- Click ‘Apply’: Your order total will update to reflect the discount.
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.
“I love my SD MACH II mattress from Sleeping Duck. The independent layers mean that I can adjust the firmness, and it can be different depending on what side you sleep on. For example, I sleep on the medium layer while my partner opted for the firm. Sleeping Duck also have a 100-day trial so you can request a different firmness option until you are completely happy.“

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:
100 night guarantee & free firmness adjustments
Sleeping Duck stands out with its generous 100 Night Guarantee, allowing you to try their mattresses and comfort items (like pillows, sheet sets, and duvets) in the comfort of your own home. If it’s not the perfect fit, you can return it for a full refund within 100 days.
Even better, during this trial period, Sleeping Duck offers free firmness adjustments. 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, ensuring your mattress is perfectly tailored to your sleep preferences. This significantly reduces the risk of buying a mattress online.
Free shipping & returns
Enjoy the convenience of 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.
Free samples
Sleeping Duck offers free samples of the different finishes available on the Indestruct bed frame, so you can get a sense of how it will fit in with your bedroom décor. There were over 50 samples across the 10 bed frame designs when we updated this article in February 2026, including wood and fabric, so the customisation options are extensive.
Sleeping Duck sales
While we’re always searching for the best offers, Sleeping Duck typically has their own sales events during the year. Keep an eye out for discounts during:
- Black Friday (November): Historically, some of the biggest savings, with up to $400+ off bundles.
- End of Financial Year (EOFY – June): A great time to snag a deal as businesses clear stock.
- Boxing Day (December): Post-Christmas sales often bring excellent opportunities.
By checking back here regularly or signing up to our deals newsletter, you’ll be among the first to know about upcoming sales and new discount codes.
Sleeping Duck FAQs: Discounts, shipping 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.
Does Sleeping Duck have a discount code 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.
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).
What is Sleeping Duck’s 100 Night Guarantee?
The 100 Night Guarantee gives you time to try out your Sleeping Duck mattress before deciding if it’s right. After getting your mattress, Sleeping Duck advises that you sleep on it for at least 21 nights to give yourself time to adjust. If it doesn’t feel right, you can contact them to return the mattress for one with a different level of firmness, or for a refund. Note that Sleeping Duck offers a return of two mattresses per household under this guarantee – so you could try out different versions of the mattress yourself, or test a couple for different people in your home.
Does Sleeping Duck have a store?
Sleeping Duck is an online retailer, but it does have a showroom in Prahran, in inner-city Melbourne, where you can view the mattress components and design elements, as well as an SD Indestruct Bed and frame, and a Palais bed in Navy. The showroom also has an ‘optimisation wall’ with all the other styles and finishes, along with free swatches, plus the full bedding range.
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).
