Who is the Koala Joey Kids Mattress for?
The Joey is for households buying a first proper mattress for a child who has moved out of a cot, roughly ages 3 to 12, and who needs a Single size that fits a standard kids bed frame. It suits parents who value a cover they can strip and machine wash after accidents, and who want a mattress with certified foam rather than an unbranded slab. It is an Australian-designed product, drawn up by Koala’s sleep team in Sydney and manufactured in China, so it sits inside a brand ecosystem that Australian shoppers already recognise.
It is also for budget-conscious buyers who prefer to pay over time. Koala lists AfterPay in four payments of 95 dollars, ZipPay from 10 dollars a week, and PayPal Pay in 4 on eligible transactions under 2,000 dollars AUD. The mattress itself is listed at a sale price of 380 dollars, a saving of 95 dollars against the regular price of 475 dollars, with an extra 100 dollars off advertised as ending Monday.
It is not for teenagers, not for adults, and not for anyone who needs a size larger than Single. Koala itself points shoppers toward the Koala SE Mattress in King Single when a bigger child needs more room, which tells you where the Joey’s ceiling sits.
What are the key specs and materials?
The Joey measures 92 cm wide, 188 cm deep and 15 cm high, and weighs 18.5 kg. It arrives in a single box measuring 102 by 28 by 28 cm with a boxed weight of 20 kg, which matters for anyone carrying it up an apartment stairwell. The build combines a polyurethane foam core with tempered steel pocket springs, a combination that gives the mattress both a foam comfort surface and a spring support base.

| Core | Polyurethane foam with tempered steel pocket springs |
| Top layer | Zip-off, 100 percent recycled polyester, machine washable |
| Top surface fibre | 100 percent TENCEL Lyocell |
| Foam certification | CertiPUR-US certified foams |

The cover story is the strongest part of the spec sheet. The top layer unzips and goes in the washing machine, and beneath it Koala has added a water-resistant protective layer aimed at night-time accidents. The foam carries antimicrobial properties described as helping prevent the growth of mould, mildew and microbes, which is a sensible claim to make on a product aimed at young children.
How does the Joey feel and support a growing child?
The Joey’s feel comes from a Kloudcell foam surface over a pocket spring base, so a child rests on responsive foam while the springs underneath react to pressure. Koala describes the Kloudcell technology as promoting breathability, comfort and responsiveness with superior longevity, and notes the foam is CertiPUR-US certified. For a child in the 3 to 12 age band, that combination offers a cushioned surface rather than a firm slab.
The 15 cm profile is the height to keep in mind. It is a purposeful kids mattress height, low enough to sit safely in a standard Single kids bed frame and light enough at 18.5 kg for a parent to rotate. Shoppers comparing it against adult mattresses should expect a different category: this is built for a child’s weight and frame, not for a 90 kg adult.
Firmness numbers are not published for the Joey, so treat any single-number firmness rating you see elsewhere as guesswork. What is on record is the construction: foam core, pocket springs, TENCEL Lyocell top fibre, recycled polyester cover.
Does the Joey sleep cool for kids?
Cooling is a topic where the Joey’s published material says less than shoppers might want. What is stated is that the top surface uses 100 percent TENCEL Lyocell fibre, a fibre commonly used for its moisture handling, and that the foam carries antimicrobial properties. Neither of those is a temperature regulation claim, so parents of hot sleepers should weigh the TENCEL top layer as a comfort detail rather than a cooling system.
The practical buyer guidance is simple: if your child sleeps hot, the zip-off top layer gives you a surface you can wash and air regularly, and you can pair the mattress with breathable bedding. Beyond that, judge the Joey on its washable cover, its certified foam and its spring support rather than on cooling technology, which is not part of its pitch.
What do motion isolation and edge support look like on paper?
Motion isolation and edge support are not covered by the Joey’s published specifications, so this page does not describe how the mattress behaves in either respect. The construction detail that bears on both is the tempered steel pocket spring unit inside a foam core.
One short piece of buyer guidance: children move around a lot in sleep, and a Single mattress has edges close to the sleeper by definition. If edge stability matters to you, check the bed frame as much as the mattress, since a slatted base with centre support changes how any mattress performs at its perimeter.

What does the Joey cost, and what do the trial and warranty cover?
The Joey is listed at 380 dollars, reduced from a regular price of 475 dollars, a stated saving of 95 dollars, with an extra 100 dollars off advertised as ending Monday. It is a Single only. Payment is splitable across AfterPay at four payments of 95 dollars, ZipPay from 10 dollars a week, or PayPal Pay in 4 on eligible transactions under 2,000 dollars AUD, with Zip’s longer plans carrying a 9.95 dollar monthly account fee and a possible establishment fee up to 99 dollars.
The trial runs 120 days, with Koala stating that if the product does not suit you it will refund the purchase entirely. Delivery is described as fast and free on mattresses, with same day delivery available on in-stock furniture and mattress orders in Sydney, Melbourne, Brisbane, Perth and Adelaide, and premium delivery including assembly and rubbish removal offered to Sydney, Melbourne and Brisbane metro customers at additional cost on select items. The warranty is described as a world class warranty of up to 10 years.
Public rating on the product page stands at 4.9 out of 5 from 244 reviews, which is a strong signal for a children’s mattress in this price bracket.
Who should not buy the Koala Joey Kids?
Skip the Joey if your child is 13 or older, if you need anything larger than a Single, or if you are buying a mattress for an adult to share with a child occasionally. The 92 cm width and 15 cm height are sized for a child’s frame, and Koala’s own recommendation to step up to the Koala SE in King Single confirms where the Joey stops being the right tool. Also skip it if you want a firmness number, a cooling system, or an in-store trial, none of which are part of this product’s published offer.
Buy it if you want a certified-foam children’s mattress with a washable top layer, a water-resistant protective layer, antimicrobial foam, a 120 day trial and a warranty of up to 10 years, at a sale price of 380 dollars for a Single. For a child aged 3 to 12 moving into their first proper bed, that is a coherent package from a brand Australian shoppers already know.
How does the Saatva Classic compare as a step-up option?
The Saatva Classic is an innerspring mattress sold in Twin, Twin XL, Full, Queen, King and larger sizes, with two heights of 11.5 and 14.5 inches and three comfort levels: Plush Soft at 3 out of 10, Luxury Firm at 5 to 7 out of 10, and Firm at 8 out of 10. It carries a 365-night home trial, free white-glove delivery with in-room setup and old mattress removal, and a lifetime warranty for the original purchaser. It is CertiPUR-US certified, GREENGUARD Gold certified, and endorsed by the American Chiropractic Association.
Read side by side, the two mattresses answer different questions. The Joey answers “what Single mattress do I buy for my 7 year old at 380 dollars”. The Saatva Classic answers “what mattress do I buy for a guest room, a teenager moving into a Full, or an adult who wants a choice of firmness and a lifetime warranty”. They are not rivals so much as sequential purchases in the same household.

Who should buy the Joey: parents furnishing a child’s Single bed, ages 3 to 12, who want a washable cover, certified foam, a 120 day trial and a 10-year warranty at 380 dollars. Who should buy the Saatva Classic: households buying for a teenager or adult who needs Twin or larger, wants to pick between three firmness levels, and values a 365-night trial, free setup with old mattress removal and a lifetime warranty.
World Sleep Almanac score: 8.2/10
Koala Joey Kids earns its mark on five criteria: price at size equality, where 380 dollars for a Single undercuts most branded kids mattresses; trial and returns, with 120 days and a full refund promise; warranty, at up to 10 years; materials and construction, with CertiPUR-US certified foam, TENCEL Lyocell top fibre and a machine-washable zip-off cover; and public reviews, at 4.9 out of 5 from 244 reviews. The score is editorial, weighted equally across those criteria, and reflects how the published offer compares in the Australian kids mattress category.

Frequently asked questions
What age is the Koala Joey Kids Mattress designed for?
Koala designs the Joey for children aged 3 to 12. It is a Single size measuring 92 by 188 cm with a 15 cm height, sized for a child’s frame rather than a teenager’s or an adult’s. Once a child outgrows that, Koala points shoppers toward the Koala SE Mattress in King Single.
Can the Joey cover be washed after accidents?
Yes. The top layer is a zip-off 100 percent recycled polyester cover that is removable and machine washable, and beneath it sits a water-resistant protective layer. The foam also carries antimicrobial properties described as helping prevent the growth of mould, mildew and microbes, which is aimed squarely at night-time accidents.
How long is the trial and what warranty comes with it?
The trial runs 120 days, with Koala stating it will refund the purchase entirely if the product does not suit you. The warranty is described as a world class warranty of up to 10 years. Delivery is fast and free on mattresses, with same day delivery on in-stock orders in Sydney, Melbourne, Brisbane, Perth and Adelaide.
Is the Joey safe for a child with allergies?
The Joey uses CertiPUR-US certified foams and a TENCEL Lyocell top surface, and the foam’s antimicrobial properties help prevent the growth of mould, mildew and microbes. Koala describes the mattress as safety certified for children, and the removable washable cover gives parents a way to keep the sleeping surface clean on a regular schedule.
Does the Joey come in sizes other than Single?
The Joey is listed in a single Standard size, Single, at 92 by 188 cm. Shoppers who need more width are directed by Koala to the Koala SE Mattress in King Single. There is no Full, Queen or larger option in the Joey line.
Verdict: The Koala Joey Kids Mattress is a well-specified Single for children aged 3 to 12, with a washable zip-off cover, a water-resistant protective layer, CertiPUR-US certified foam, tempered steel pocket springs, a 120 day trial and a warranty of up to 10 years, all at a sale price of 380 dollars. Buy it for a child moving into their first proper bed. Do not buy it for a teenager, an adult, or anyone who needs larger than Single, and do not buy it if you want a published firmness rating or a dedicated cooling system. When that child outgrows the Single, the Saatva Classic in Twin or Full, with its 365-night trial, free white-glove delivery and lifetime warranty, is the natural next step.
