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

Going for practically half price across all sizes, this is arguably one of the best deals we've seen on any mattress since EOFY! Getting a queen size for under AU$600 is ridiculously cheap, and that means you can get a king for AU$636! If that isn't a bargain, we don't know what is. Just from a budget point of view, this is an excellent mattress to invest in, but please note that our reviewer found it sleeps firmer than rated by the manufacturer and may not suit all kinds of sleepers. So it's a good thing you get a lengthy 120-night trial.

We haven't reviewed this specific Origin mattress ourselves, but we loved its cheaper sibling in our Origin Hybrid Mattress review. However, at 38% 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.

While we didn't score the Emma Luxe Pro mattress review very well due to it not feeling as 'luxe' as we had expected and found the materials used to be of poorer quality, it might well suit some sleepers. And given its 45% discount, it would be remiss if we didn't list the Luxe Pro here, with its better cooling cover over the standard Luxe model.

Score a fantastic 56% off this 5-star mattress from Onebed, using the code BFSALE20 at checkout. According to our reviewer, it's slightly softer than what she experienced in her Origin Hybrid Mattress review, but she preferred Onebed's adjustable firmness layer. 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.

All the Ergoflex 5G mattress sizes are discounted by the same 30%, but we've picked the double as that brings the price down to under AU$1,000. You will need to apply the code BLACK 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 a different size memory foam option, the Ergoflex 5G should be your port of call for a discount.

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$400 discount across all sizes — and brings the king size to an affordable AU$850. 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 only gets a 39% discount on the king, that's a significant saving on the biggest size. This mattress, 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.
