About Sleeping Duck

Sleeping Duck is an Australian mattress maker based in Prahran, Victoria, selling the Mach II adjustable-firmness mattress, the SD Indestruct Bed base, BreatheTech covers, pillows, sheets, duvets and bundles direct.

The term that matters most is the 100-night trial: firmness tweaks are free, and if the mattress still doesn't suit you, Sleeping Duck collects it and refunds you.

Sleeping Duck builds the Mach II as a customisable mattress system, using twice-tempered steel springs and foam that carries Global Green Tag certification, and backs the mattress with a 10-year warranty. Alongside the mattress and bed base, the range includes the AntiGravity (AG) pillow, and shoppers weighing a finish for the SD Indestruct Bed can order free sample swatches first.

The brand has featured on Shark Tank and lists two Champion Awards from 2022, for customer service and service excellence. It runs a showroom in Melbourne and a corporate and trade sales desk, while a separate US store is supported by a team based in California.

Does Sleeping Duck offer free shipping?

Yes. Every order ships free to your door, and metro addresses get next-business-day delivery; the exact timing appears at checkout.

What is Sleeping Duck's return policy?

You get 100 nights with the Mach II, and an unhappy sleeper gets a free pickup and a refund.

More about shopping at Sleeping Duck

Firmness: Start with medium or firm, then adjust the Mach II at home at no cost if it feels wrong.
Warranty: The mattress carries a 10-year warranty, which runs long after the trial nights are over.
Finance: Interest-free finance lets you spread the cost of a mattress, base or bundle instead of paying it all up front.
Bed samples: Finish samples for the SD Indestruct Bed are free to order, so you can see the options at home.

How to use a Sleeping Duck discount code

Sleeping Duck sells direct from its Australian site, so a discount code goes in during checkout, the step where your delivery details are confirmed.
Check that the AUD total drops before you pay or pick interest-free finance.
If you're weighing a bundle against single items, try the code on both baskets and compare the totals.
Free delivery and the 100-night trial come with the mattress whichever price you pay, so treat a code as a bonus on top of those terms rather than a reason to rush the decision.

More ways to save at Sleeping Duck

Much of the value at Sleeping Duck is built into the order rather than a code.
Delivery costs nothing, and firmness changes on the Mach II are free at home.
The 100-night trial means a mattress that doesn't work out can go back for a refund.
Order the free SD Indestruct Bed finish samples before choosing a base, so you don't pay for a finish you'd swap later.
Interest-free finance spreads the cost when a mattress and base together stretch the budget.

Sleeping Duck questions, answered

How long is the Sleeping Duck mattress trial?

You get 100 nights to sleep on the Mach II. If adjusting the firmness doesn't fix it, Sleeping Duck collects the mattress free of charge and refunds you.

Does Sleeping Duck charge for delivery?

Delivery is free on every order. Metro addresses get it the next business day, and checkout shows the details for your address.

Can you change the firmness of a Sleeping Duck mattress?

The Mach II starts as medium or firm, and you can adjust it at home at no cost. Those adjustments stay free throughout the 100-night trial.

What warranty comes with the Mach II mattress?

Sleeping Duck puts a 10-year warranty on the mattress, separate from the 100-night trial.

Can you pay for a Sleeping Duck mattress over time?

Interest-free finance is available, so you can spread the cost of a mattress or bundle. Check the finance option at checkout for its terms.

Can you see SD Indestruct Bed finishes before buying?

Sleeping Duck sends finish samples for the SD Indestruct Bed free, so you can compare them in your own room first.
