The Onebed Original is one of the best-value adjustable mattresses in Australia: an all-foam bed-in-a-box with a flippable comfort layer that lets you dial the feel between medium and medium-firm without buying a new mattress. The current 11-inch (28cm) generation adds a taller profile, a 5-zone support layer and reinforced edges, while keeping the cooling and low motion transfer owners already rate highly.
That makes it a smart pick for anyone who is not sure of their ideal firmness, couples who disagree on feel, or value shoppers who still want a long trial and warranty. In this review we break down how it is built, how it feels, what it costs across all sizes, and who should (and should not) buy it.
Sleep Society rating
Onebed Original ★★★★☆ 4.3/5
Firmness: Adjustable (Medium / Medium-firm, ~6/10) | Queen: $1,095 (check current price) | Trial: 125 nights | Warranty: 15 years
How it scores
Value is the standout: you get an adjustable, dual-certified foam bed with a 125-night trial and 15-year warranty for well under most rivals. Comfort and perks score high; quality loses a little for occasional long-term durability reports, and adjusting the feel takes a bit of effort.
The bottom line
The Onebed Original is the mattress to buy when you want adjustable comfort without a premium price. Flip the top layer to move between a medium and medium-firm feel, enjoy genuinely low partner disturbance and cooling gel foam, and lean on a 125-night trial and 15-year warranty to remove the risk. It is all-foam, so it lacks the bounce and airflow of a spring hybrid, and a few owners note softening over years of heavy use, but as a value adjustable bed it is very hard to beat.
We assess every mattress on the same five criteria – quality, value, comfort, ease of use and perks – using the brand’s published construction, aggregated owner reviews from ProductReview.com.au and CHOICE, and hands-on assessment of the feel, cover and setup. We re-check pricing on the brand’s live page at each update.
The Onebed Original suits sleepers who are unsure of their ideal firmness, couples who disagree on feel, and value shoppers who still want a long trial and warranty. The cooling gel foam and breathable comfort layer also make it a fair pick for our hot sleeper and side sleeper guides. Dedicated bounce-and-airflow fans, and heavier sleepers who want zoned spring support, are better served by a hybrid like the Origin.

"No aches or pain anymore just a great night's sleep. I have now found my dream mattress. Took me a few sleeps to get used to it. I love the mattress" - Onebed Mattress Review
The Onebed Original is a 28cm (11-inch) all-foam mattress built around adjustability. From the top:
Flipping the comfort layer inside the cover changes the firmness between medium and medium-firm (around 6/10). The foams are CertiPUR-US and Oeko-Tex certified, and the mattress ships compressed in a box.

With the memory foam side up the Onebed sits at a balanced medium, cradling the shoulders and hips while the 5-zone base holds the spine level. Flip to the Auralux side for a medium-firm feel with more push-back, which back and stomach sleepers and heavier bodies tend to prefer.
As an all-foam bed it isolates motion well, so a restless partner is unlikely to wake you, and the reinforced edges make the whole surface usable.
The cooling gel-infused memory foam and breathable comfort layer run cooler than dense traditional memory foam, though a pocket-spring hybrid will always move more air.
There is a mild new-foam smell on unboxing that clears within a day in a ventilated room.

The Onebed Original starts around $795 for a single and runs to about $1,255 for a king, with a queen near $1,095 at current sale pricing. That places it firmly at the value end of the bed-in-a-box market for an adjustable, dual-certified foam bed with a 125-night trial and 15-year warranty. Onebed discounts heavily and often, so check the live price before you buy.
"I was very concerned when we first received our mattress as it was a lot firmer than our previous one. But from the first night I’ve had a great sleep, no more back pain and a month later it is still in exactly the same condition as when we bought it. And the dog couldn’t wait to get it upstairs before lying on it!" - Mattress Review

Onebed ships free Australia-wide. The mattress arrives compressed and rolled in a box; you slide it onto your base, cut the plastic and it expands within a few hours. Returns during the trial are free and Onebed arranges collection, with returned mattresses donated to charity rather than sent to landfill, so you are not left disposing of a mattress yourself.
With a 15-year warranty and CertiPUR-US and Oeko-Tex certified high-density foams, the Onebed Original is built to reach the typical 7–10 year mattress lifespan and beyond. Rotating it head-to-toe every few months and using a mattress protector will keep it in shape; a minority of long-term owners do report some softening after years of heavy use, which the flippable comfort layer can help offset by giving you a fresher-feeling side.
Yes. Unzip the cover and flip the top comfort layer to switch between a medium feel (gel memory foam side up) and a medium-firm feel (Auralux side up). It takes a few minutes and needs no tools.
In its medium setting the gel memory foam cushions the shoulders and hips well for side sleeping, while the 5-zone base keeps the spine aligned.
It runs cooler than dense traditional memory foam thanks to the cooling gel-infused comfort layer, but a pocket-spring hybrid will always be more breathable.
The Onebed is already one of the cheapest adjustable foam beds. If you want a hybrid with more bounce, a pocket-spring bed like the Origin is worth comparing, and the Emma is a close all-foam rival with zoned support.
