The best mattress sales in Australia in September 2025: score the best price on our top-rated mattresses

We haven't reviewed this specific Origin mattress ourselves, but we loved its cheaper sibling in our Origin Hybrid Mattress review. However, at 33% off, we think it represents excellent value for money as this adds a removable cover and a flippable adjustable firmness layer that's not available on any other Origin mattress. And given we think both the Hybrid and the LumbarCloud offer excellent orthopaedic support, we think the Hybrid Plus will too. And a queen size can be yours for just under a grand, along with one free pillow worth AU$179.

We're in the process of reviewing this mattress but early impressions are quite positive. According to our reviewer, it's slightly softer than what she experienced in her Origin Hybrid Mattress review, but otherwise sleeps very much the same. And at half price, that's excellent value for money as it's currently cheaper than the competition. If you're not convinced, Onebed gives you 125 nights to try it out yourself.

While we didn't score the Emma Luxe mattress review very well due to the poorer quality of materials used and as its lack of pressure relief, it might well suit some sleepers. And given its 30% discount, it would be remiss if we didn't list the Luxe Plus here, with its better cooling cover over the standard Luxe model.

All the Ergoflex 5G mattress sizes are discounted by the same 25%, but we've picked the double as that brings the price down to under AU$1,000. You will need to apply the code TAKE25 at checkout, but it's important to note that this is the only all-foam (memory) mattress on this page that gets a discount this September. So if you aren't keen on a hybrid mattress and need of a different size memory foam option, the Ergoflex 5G should be your port of call for a discount.

Admittedly this isn't a great discount as AU$100 may not be here or there, but Macoda has just the one mattress in its arsenal that stands out from the competition by offering two memory foam layers that are both flippable to adjust between plush, medium and firm – all three in one bed! No need to tussle with customer service for changing out your foam. Note that Macoda gives you 100 nights to try the various firmness options, although we suspect you'll find your right one without needing to organise a return.

More often than not, the bigger mattress sizes tend to be quite expensive, even when discounted. However, this hybrid option is fantastic value for money with the current AU$385 discount across all sizes — and brings the king size to an affordable AU$865. Not only is it our pick for the best mattress for side sleepers, but it scored well in our Valmori Hybrid Mattress II review for being a suitable all-rounder.

While the Origin website says the LumbarCloud – its most premium mattress – gets the highest discount (45% off), it's actually only just 31% off for the king size. Still that's a significant saving on the biggest size, and a mattress that we said was like sleeping on a cloud in our Origin LumberCloud review, and that's without compromising orthopaedic support. If that's the kind of comfort you're after, take advantage of this offer, which also gets you two free pillows worth AU$358.
