The Koala Plus is Koala’s flippable mid-range mattress and the successor to the discontinued Calm As. Its stand-out feature is Flippable Firmness: unzip the cover and flip the internal Kloudcell layer to switch between medium-firm and firm. A reversible seasonal cover adds a cooling side for summer and a cosy side for winter, and five support zones plus a Zero Disturbance base round out a 28cm all-foam build.
On paper it is a well-made, adaptable bed. In practice it carries a premium price with no standing discount, a 120-night trial that is shorter than several rivals, and an all-foam feel that gives up the bounce and airflow of a spring hybrid. In this honest review we break down how it is built, how it feels, what it costs across all six sizes, and where your money goes further.
If you want the short version: the Koala Plus is a solid mattress, but at this price the hybrids we rate highest – the Origin, the Emma Comfort and the value-led Newentor Hybrid – give most sleepers more bed for less money.
Sleep Society rating
Koala Plus ★★★★ 4.0/5
Firmness: Flippable (medium-firm / firm) | Queen: $1,650 | Trial: 120 nights | Warranty: 10 years
How it scores
Quality and comfort are good for an all-foam bed and the flippable firmness is genuinely easy to use; value is the weak point because you pay full RRP with no standing sale and a shorter 120-night trial, so hybrids at the same price score higher on what you get for your money.
The bottom line
The Koala Plus is a genuinely adaptable all-foam mattress: flip the Kloudcell layer for two firmness levels, flip the cover for two seasons, and enjoy strong motion isolation for couples. But at $1,650 for a queen with a 120-night trial and no standing discount, it is priced like a premium hybrid without the bounce or airflow of one. Most sleepers will get more support, better cooling and better value from the Origin, Emma Comfort or Newentor Hybrid.
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 Koala Plus suits couples who want strong motion isolation and sleepers who like to fine-tune firmness and adapt to the seasons without buying a new bed. The flippable layer and reversible cover are real, useful features and the foam feel is comfortable.
For most other sleepers, though, our affiliate-tested favourites are the smarter buy at this price. If you want zoned pocket-spring support and better airflow, the Origin is our top-rated hybrid. If you want a balanced all-rounder from a global brand with a longer trial, look at the Emma Comfort. And if budget is the priority, the Newentor Hybrid delivers hybrid support for far less.

"I bought two double mattresses for each of my teenage boys. They said they are having the best sleep ever. My problem is trying to get them out of bed now.Everyone at Koala were very helpful, I had a lot of questions before buying and they were all answered professionally. Even the delivery guy was fantastic." Koala Review
The Koala Plus is a 28cm all-foam mattress built around adjustability. From the top:
The mattress ships compressed in a box and expands within a few hours. The comfort layer and cover are both reversible, which is what gives the Plus its two-feel, two-season flexibility.
Origin Mattress
The Best Value for Money Hybrid Mattress In Australia → Origin Mattress
With the Kloudcell layer flipped to its medium-firm side (around 6.5/10) the Plus holds the spine level with a cushioned contour that suits most back and side sleepers. Flip it to firm (around 7/10) for more support, better for stomach sleepers and heavier bodies. It is a real adjustment, though not as fine-grained as a three-layer system. Sleepers who want zoned pocket-spring support will still prefer a hybrid like the Origin.
This is where the Plus shines. As an all-foam bed with a Zero Disturbance base it isolates motion very well, so a restless partner or a shift-worker getting up early is unlikely to wake you.
The CoolThread cover side and gel-infused Kloudcell foam help, and Koala markets the Plus as sleeping cooler than leading online brands. Even so, all-foam beds trap more heat than pocket-spring hybrids; dedicated hot sleepers will run cooler on the airflow of the Newentor Hybrid or Origin.
There is a mild new-foam smell on unboxing that clears within a day in a ventilated room.

The Koala Plus starts at $1,050 for a single and runs to $2,290 for a super king, with a queen at $1,650 and a king at $1,990. That is premium-hybrid money for an all-foam bed, and Koala rarely discounts the Plus, so you usually pay full RRP. At this price we think the zoned support and airflow of a pocket-spring hybrid represent better value for most sleepers.

"Literally everything about this mattress was awesome. Same day delivery with tracking, the affordable price tag and the mattress itself is comfortable.. And the best part? I can't feel it when my partners gets out of bed in the morning. What more could you want!" Customer Review
The Koala Plus ships free to metro areas across Australia, with same-day delivery available in Sydney, Melbourne, Brisbane, Perth and Adelaide on in-stock orders. It arrives compressed in a box (roughly 100 x 43 x 43cm, about 23kg to carry) that you slide onto your base before cutting the plastic; it expands within a few hours. Returns during the trial are handled by Koala.
A 120-night trial and 10-year warranty are fair but no longer market-leading. If a longer safety net matters to you, the Emma Comfort offers a longer trial.
With a 10-year warranty and high-density foams, the Koala Plus should last around the typical 7–10 year mattress lifespan. Rotating it head-to-toe every few months and using a mattress protector will help it hold its shape. Note the warranty is shorter than the 15-year cover some rivals offer.
Yes. Unzip the cover and flip the internal Kloudcell layer to switch between a medium-firm and a firm feel. It takes a few minutes and needs no tools, though it is two settings rather than a full range.
On its medium-firm side it cushions the shoulders and hips reasonably well for side sleeping. Side sleepers who want more contour or zoned relief may prefer a hybrid like the Origin.
The CoolThread cover and gel-infused foam help, but as an all-foam bed it traps more heat than a pocket-spring hybrid such as the Newentor.
Yes. At the Plus’s price you can buy a zoned hybrid like the Origin or Emma Comfort, or save money with the Newentor Hybrid, all of which we rate more highly for value.
