The Koala Plus Mattress is positioned as an advanced Kloudcell foam option with multi-zone support and seasonal fabric sides. Koala markets it around a simple promise: fall asleep faster, sleep deeper, recover better. The brand’s own product page lists a 4.8 out of 5 rating across 1,470 reviews, a 120 day trial, and a warranty of up to 10 years. This page looks at what the specifications actually say, who the Plus suits, and where a different mattress makes more sense.

Who is the Koala Plus Mattress for?
The Koala Plus is built for sleepers who want foam comfort with a firmness dial built in. Its Kloudcell comfort layer flips to switch between medium-firm and firm, so one mattress covers two support settings. It suits Australians who value a boxed foam mattress, a 120 day trial, and a 10 year warranty, and who sleep alone or with a partner of similar build. It is less suited to anyone who wants a coil feel or a very soft, plush surface.
Reading the product page closely, three groups get the most from this mattress:
- Adjustable-firmness sleepers. The flip layer means you can change your mind after delivery rather than guessing at firmness before you buy.
- Warm and cool sleepers sharing a bed. Koala describes the Plus as keeping you cool in summer and warm in winter, with a summer side and a winter side in the ticking fabric.
- Boxed-mattress buyers. The Single arrives in a box at 23.2 kg, with assembly instructions and a video, so delivery and setup stay simple.
What are the Koala Plus specifications?
The core numbers are straightforward: 28 cm height, CertiPUR-US certified polyurethane foam, designed in Sydney and manufactured in China, with a 120 day trial and a warranty of up to 10 years. The mattress is listed at $1,050, and the range runs from Single to Super King.
| Specification | Koala Plus Mattress |
|---|---|
| Height | 28 cm |
| Single dimensions | H 28 cm x W 92 cm x 188 cm |
| Queen dimensions | H 28 cm x W 153 cm x 203 cm |
| King dimensions | H 28 cm x W 183 cm x 203 cm |
| Single weight | 21.00 kg |
| Foam certification | CertiPUR-US certified |
| Country of origin | Designed in Sydney, manufactured in China |
| Trial | 120 days |
| Warranty | Up to 10 years |
| Listed price | $1,050 |
Sizes offered are Single, King Single, Double, Queen, King and Super King. The King Single measures H 28 cm x W 107 cm x 203 cm, the Double H 28 cm x W 138 cm x 188 cm, and the Super King H 28 cm x W 203 cm x 203 cm.
How does the adjustable firmness actually work?
The firmness adjustment is mechanical rather than electronic: you flip the Kloudcell comfort layer to choose between medium-firm and firm. That is the whole mechanism, and it is the Plus’s clearest selling point. There are no pumps, no remote, and no app. The mattress body stays the same; only the orientation of the comfort layer changes.
For buyers, this matters in a practical way. If you order medium-firm and find it too soft after a few weeks, you do not start a return process, you flip a layer. The trade-off is that the range stops at firm. There is no plush or soft setting in the Plus, so sleepers who want a body-hugging, deeply cushioned surface should look elsewhere in the market.
Koala also sells the Polar+ in the same family, listed as 5 degrees cooler with PolarBands and described as offering ultimate cooling with all the benefits of Plus. The Plus carries seasonal regulation and adjustable firmness, while the Polar+ adds that dedicated cooling system.
What materials are inside the Koala Plus?
The build is foam first. Polyurethane foam is listed as the other material, and the foams carry CertiPUR-US certification, which means they are made without formaldehyde, ozone depleters, heavy metals and flame retardants (PBDEs, TDCPP or TCEP), and promote indoor air quality with low volatile organic compounds.
The fabric layers are specified in detail, and they reveal the seasonal design:
- Summer side ticking: 81 percent polyester, 19 percent polyethylene.
- Winter side ticking: 35 percent organic cotton, 13 percent polyester, 52 percent recycled polyester.
- Side wall fabric: 65 percent polyester, 35 percent recycled polyester.
- Anti-slip base fabric: 100 percent polyester with PVC dot.
The two-sided ticking is the physical expression of Koala’s temperature claim. The summer side leans on polyester and polyethylene, the winter side brings in organic cotton and a majority of recycled polyester. Turning the mattress with the seasons is a low-tech answer to temperature regulation, and it pairs with the firmness flip: two adjustments, both manual, both free.
How does the Koala Plus handle cooling?
Koala’s temperature story for the Plus rests on two things: the seasonal ticking sides and the brand’s description of advanced temperature regulation. The summer side and winter side fabrics let you change the surface against your skin without changing mattresses. The product copy states the Plus keeps you cool in summer and warm in winter, creating what the brand calls the perfect sleep environment to recharge.
Buyers comparing within the Koala range should note where cooling sits. The Polar+ is the cooling specialist, listed at 5 degrees cooler with PolarBands. The Plus carries seasonal regulation rather than that dedicated cooling system. If you sleep hot in a warm climate and cooling is your main priority, the Polar+ is the model Koala points to for that job. If you want one mattress that adapts across seasons and gives you firmness choice as well, the Plus is the balanced pick.
What do the trial, warranty and delivery look like?
The ownership terms are among the clearest facts on the page. Koala offers a 120 day trial, described as trying the mattress risk-free, a world class warranty of up to 10 years, and free delivery on mattresses. Same day delivery is offered on furniture and mattress orders in Sydney, Melbourne, Brisbane, Perth and Adelaide for in-stock products.
Sydney, Melbourne and Brisbane metro customers can select premium delivery that includes assembly and rubbish removal on select items at an additional cost. The Single ships in a box measuring W100 x D43 x H43 cm at a boxed weight of 23.2 kg, with assembly instructions and an assembly video provided.
Payment options are listed in depth. Afterpay splits the purchase into four interest-free payments, with the page showing 4 payments of $262.50 and availability on orders less than $3,000. ZipPay and PayPal Pay in 4 are also listed, along with a Zip credit option of $1,000 to $5,000 with 3 to 24 months interest free, a $9.95 monthly account fee or $0 if nothing is owing, and a one-off establishment fee up to $99 that may apply. A sign up offer of 10 percent off is shown on the page.

Who should buy the Koala Plus, and who should skip it?
Buy the Koala Plus if you want one mattress with two firmness settings, seasonal fabric sides, a 120 day trial and a warranty of up to 10 years, at a listed price of $1,050. It is a foam mattress designed in Sydney and manufactured in China, with CertiPUR-US certified foams and a 28 cm profile across all sizes from Single to Super King. The flip layer gives you medium-firm or firm, and the summer and winter ticking give you two surface textures. Koala’s own page shows 4.8 out of 5 across 1,470 reviews, which is a strong public signal for a mattress in this price bracket.
Skip the Koala Plus if you want a coil mattress, a plush or soft feel, or a trial longer than 120 days. The Plus tops out at firm, so sleepers who need deep cushioning will not find it here. Anyone who prefers the responsive, bouncy support of springs rather than foam should consider an innerspring model instead. And if a longer trial matters to you, Saatva’s Classic carries a 365 night home trial against the Koala’s 120 days.
The choice also comes down to geography and service style. Koala offers same day delivery in five Australian capitals and boxed setup at home. Saatva delivers in the United States with free white-glove delivery, in-room setup and old mattress removal at no cost. Where you live and how you like to receive a mattress will decide as much as the foam or coil question.
How does the Koala Plus compare with the Saatva Classic?
These are two different answers to the same problem. The Koala Plus is an all-foam, boxed, adjustable-firmness mattress sold in Australia with a 120 day trial and up to 10 years of warranty. The Saatva Classic is an innerspring mattress with a dual-coil design of triple-tempered recycled carbon steel coils, a 3 inch Euro pillow top, three comfort levels, two heights, and a 365 night home trial with a lifetime warranty.
| Feature | Koala Plus Mattress | Saatva Classic |
|---|---|---|
| Type | All-foam with Kloudcell layer | Innerspring with dual-coil design |
| Height | 28 cm | 11.5 or 14.5 inches |
| Firmness choice | Medium-firm or firm, by flipping the comfort layer | Plush Soft 3/10, Luxury Firm 5 to 7/10, Firm 8/10 |
| Trial | 120 days | 365 nights |
| Warranty | Up to 10 years | Lifetime |
| Delivery | Free on mattresses, same day in five capitals | Free white-glove delivery and setup, old mattress removal |
| Certifications | CertiPUR-US certified foams | CertiPUR-US certified foams, GREENGUARD Gold certified |
| Market | Australia | United States |
Who should buy the Koala Plus: Australian shoppers who want a boxed foam mattress with firmness adjustment, seasonal fabric sides and a mid-range price, and who are comfortable with a 120 day trial. It also suits renters and apartment dwellers who value a mattress that arrives in a box and can be moved without a delivery crew.
Who should buy the Saatva Classic: Shoppers who want a coil mattress with a Euro pillow top, three comfort levels to choose from, chiropractor-approved Lumbar Zone support, and a 365 night trial backed by a lifetime warranty. It suits couples who cannot agree on firmness, since Luxury Firm is designed for all sleep positions, and heavier sleepers, since Firm is described as ideal for body types around 250 to 300 pounds.
What does the Koala Plus cost in each size?
The brand page lists the mattress at $1,050 with a 20 percent off promotion shown, and Afterpay at 4 payments of $262.50. Prices for individual sizes are not broken out on the page, so the honest guidance is to check the current price for your size before ordering. The size list itself is complete: Single, King Single, Double, Queen, King and Super King, all at 28 cm height.
Financing is a real part of the value here. Afterpay is available on orders less than $3,000, ZipPay on orders up to $5,000 with a $1,000 credit limit, and the Zip credit product runs from $1,000 to $5,000 with 3 to 24 months interest free. Read the fee structure before you commit: the Zip options carry a $9.95 monthly account fee or $0 if nothing is owing, and a one-off establishment fee up to $99 may apply.
What are the main questions buyers ask?
How long can I try the Koala Plus Mattress?
Koala offers a 120 day trial, described on the product page as trying the mattress risk free. That is roughly four months of nights to decide, which is shorter than Saatva’s 365 night trial but in line with many boxed mattress brands. Use the trial to test both firmness settings: flip the Kloudcell layer partway through so you experience medium-firm and firm before the window closes.
What warranty does the Koala Plus carry?
The warranty is described as a world class warranty of up to 10 years. The phrase “up to” means the exact coverage depends on the terms Koala applies, so read the warranty document that ships with the mattress. For comparison, the Saatva Classic carries a lifetime warranty for the original purchaser against defects in workmanship and materials under normal residential care and use.
Is the Koala Plus a good choice for hot sleepers?
The Plus handles temperature with a summer side and a winter side in the ticking fabric, plus Koala’s description of advanced temperature regulation. The summer side is 81 percent polyester and 19 percent polyethylene, while the winter side is 35 percent organic cotton, 13 percent polyester and 52 percent recycled polyester. If cooling is your main concern and you want a dedicated cooling system, Koala’s Polar+ is the model listed at 5 degrees cooler with PolarBands.
Does the Koala Plus come assembled?
The Single arrives boxed at W100 x D43 x H43 cm and 23.2 kg, with assembly instructions and an assembly video. Same day delivery is available in Sydney, Melbourne, Brisbane, Perth and Adelaide for in-stock products, and premium delivery with assembly and rubbish removal is available to Sydney, Melbourne and Brisbane metro customers on select items at an additional cost.

World Sleep Almanac score: 7.6/10
The World Sleep Almanac editorial score for the Koala Plus Mattress is 7.6 out of 10. The rating is editorial, based on five criteria: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. On price, the listed $1,050 is competitive for a mid-range foam mattress with adjustable firmness. On trial and returns, 120 days is solid but shorter than the 365 night standard set by premium brands. On warranty, up to 10 years is good rather than exceptional. On materials, CertiPUR-US certified foams and detailed fabric specifications with recycled content are a genuine plus. On public reviews, 4.8 out of 5 across 1,470 reviews is a strong signal. Our scoring method weights these five criteria equally, and we will update the score if a factual element such as price, trial length or warranty changes.

Verdict: should you buy the Koala Plus Mattress?
Buy the Koala Plus if you are in Australia, want a foam mattress with real firmness adjustment, and like the idea of seasonal fabric sides. Skip it if you want coils, a plush feel, or a trial longer than 120 days. The flip layer is the standout feature: medium-firm or firm, changed by hand, no return process needed. The 28 cm profile, six sizes, CertiPUR-US certified foams and 4.8 out of 5 rating across 1,470 reviews make it a well-documented product. The 120 day trial and up to 10 year warranty are the terms to weigh against alternatives.
