How to apply your Sleeping Duck discount 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.

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.
