The Koala Calm As is a discontinued, all-foam mattress with a reversible comfort layer that offers two feels: medium-firm and firmer. It can make sense for couples who value low motion transfer and for sleepers who want to change firmness without replacing the mattress, but buying one now requires extra caution. ProductReview.com.au lists the model as discontinued, so stock, seller legitimacy, trial rights and warranty eligibility must be confirmed before payment. Historical testing found good cooling, useful edge support and limited partner disturbance, while individual experiences varied substantially.
What is the Koala Calm As mattress?
The Koala Calm As is a mattress-in-a-box built entirely from foam. Its distinguishing feature is a flippable firmness layer: one orientation is intended to feel medium-firm and the other firmer. Rather than changing a mechanical setting, you unzip or otherwise access the comfort construction as designed and turn the layer over, then use the surface that suits you better.

Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →Tom’s Guide described a 1 cm plush cover over the foam construction and a polyester anti-slip base with PVC dots. That base is intended to limit movement on a suitable bed platform. The review also reported GECA and CertiPUR-US certifications on the foam at the time of testing; certification status should not be assumed to apply to a later replacement, stored unit or marketplace listing without documentation.
The product arrives compressed in two boxes. One contains the main mattress base and the other contains the rolled flippable layer. This is different from a single-box bed, so plan where each box will be opened and how the heavier base will be moved before delivery.

Is the Koala Calm As worth buying?
It is potentially worthwhile only when the seller can establish that the mattress is genuine, unused or acceptably preserved, and covered by clearly stated return terms. The design offers a practical choice between two firmness levels, and controlled review testing found low motion transfer, reasonable edge support and effective cooling. Those advantages are offset by the model’s discontinued status and by the fact that comfort is highly personal.
A new purchase through Koala’s normal channel would ordinarily be easier to evaluate because the official policy describes a home trial. A discontinued unit offered by a marketplace or another owner may not receive the same treatment. Before paying, obtain the exact model name, manufacturing or purchase documentation, condition, delivery arrangements and written return policy. Do not assume that a historical review-page price or the original brand policy automatically applies to a current listing.
How firm is the Koala Calm As?
Tom’s Guide estimated the firmer surface at about 7/10 and the medium-firm surface at about 6.5/10. These are reviewer estimates, not an official Koala numerical rating. The plush cover makes each side feel slightly softer than the underlying foam might suggest, and body weight, sleeping position and the support underneath can change the perceived result.
| Surface | Tom’s Guide estimate | What it means in practice |
|---|---|---|
| Firmer side | About 7/10 | More resistance and a less yielding feel than the reverse side. |
| Medium-firm side | About 6.5/10 | A little more give while remaining in the medium-firm range. |
Because the difference is modest rather than dramatic, flipping the layer is best viewed as fine-tuning, not as converting a soft bed into an extra-firm orthopedic surface. If one partner needs a very soft feel and the other needs very firm support, a single shared mattress may still involve compromise.
How does it perform for motion, heat and edge support?
Tom’s Guide reported minimal motion transfer, decent edge support and good cooling after extended use. Those observations suggest a useful balance for an all-foam bed, but they are not laboratory scores and do not guarantee the same result in every bedroom.
Motion isolation
Low motion transfer is one of the strongest reasons to consider this model for couples. Foam generally absorbs movement rather than transmitting it through springs, and the reviewer found that a partner’s movement was not strongly disruptive. Your result can still change with body weight, the bed base and how close each sleeper is to the edge.

Heat management
The extended-use review described cooling performance as good. That is encouraging for sleepers who dislike a warm mattress, yet room temperature, bedding, clothing and individual metabolism all influence heat. A positive cooling observation should not be read as a guarantee that every hot sleeper will remain comfortable through summer.
Edge support
Edge support was judged decent rather than exceptional. That can make sitting down or using more of the sleep surface practical, but it is not equivalent to the rigid perimeter found on some hybrid or innerspring designs. If you regularly sit on the edge, test that area during the home trial whenever possible.
Comfort across sleeping positions
Tom’s Guide found the mattress comfortable for several sleeper types while emphasizing that feel is personal. The reversible layer gives you two starting points, but it cannot correct every mismatch in pressure relief, spinal alignment or shoulder and hip comfort. Pay attention to how your body feels after a full night and again after several consecutive nights rather than judging solely by a brief lie-down.
What are the Koala Calm As specifications?
CHOICE lists the Queen model as a 29.5 cm-thick foam mattress-in-a-box with 19 layers and a listed weight of 37 kg. The dimensions and prices below come from that review page. CHOICE does not expose a publication year for these figures, so the prices are historical page values, not current quotations.
| Specification | Queen listing | Qualification |
|---|---|---|
| Construction | Foam mattress-in-a-box | Firmness was tested in the firm configuration. |
| Number of layers | 19 | CHOICE listing; individual layer materials are not detailed there. |
| Thickness | 29.5 cm | CHOICE listing. |
| Weight | 37 kg | CHOICE listing for Queen. |
| Dimensions | 204.5 × 154.5 × 29.5 cm | CHOICE listing for Queen. |
| Listed price | $1,700 | Historical CHOICE review-page value; not a current quote. |
| Price paid after sale or bargaining | $1,550 | Historical CHOICE review-page value; not a recurring offer. |
The 37 kg figure applies to the Queen listing and may not describe the weight of the shipping cartons or a different size. Confirm dimensions, weight and included components with the seller, especially when buying a stored or second-hand unit.
How do you set up the Koala Calm As?
Setup is straightforward in principle but physically demanding because the main carton is heavy. The mattress must be placed on its support before you finish unwrapping and arranging the layers.

- Prepare the room and base. Clear a path from the delivery point to the bed and install a supported, ventilated base that meets Koala’s spacing guidance.
- Identify both cartons. The main base and the rolled flippable layer arrive separately. Keep the second carton nearby so it is not mistaken for packaging waste.
- Move the main box into position. Tom’s Guide found the main box heavy to move; use a second person rather than dragging it across the floor or attempting a risky solo lift.
- Unwrap the base on the bed. Position the compressed mattress on the support before removing its packaging, following the orientation marks or instructions supplied with the unit.
- Open and place the rolled layer. Unwrap the second box and lay the flippable layer over the base as directed.
- Choose the starting surface. Use the medium-firm orientation first if you prefer a little more give, or the firmer orientation if you want more resistance. Keep the alternative orientation available so you can make a deliberate comparison.
- Check the whole sleep surface. Confirm that the cover and layer are lying flat and that the anti-slip base is contacting the platform evenly before making the bed.
Do not discard cartons or paperwork until you have checked the mattress and confirmed the seller’s return conditions. For a discontinued model, packaging and documentation can be especially important if a return or warranty question arises.
What bed base does the mattress require?
Koala’s official FAQ recommends a supported, ventilated base and says slats should be no more than 7.5 cm apart. A base with wider gaps may fail to support the foam evenly and could affect comfort or durability.

If your bedroom uses an adjustable frame, obtain written confirmation for the specific model and usage pattern rather than assuming that a flat-mattress warranty covers prolonged articulation.
- Measure slat spacing before delivery; the stated maximum is 7.5 cm.
- Check that the platform is ventilated and provides continuous, even support.
- Inspect for sharp edges, protruding hardware or damaged slats that could catch the cover.
- Ask a seller to confirm whether the mattress has been used on an adjustable base and for how long.
What is the Koala Calm As trial period and return policy?
Koala’s official FAQ describes a risk-free 120-night home trial with a full refund if the mattress is unsuitable. That policy is the clearest way to evaluate a personal comfort product because it allows repeated nights in your own room rather than a short showroom test.
The qualification is important: a current listing may not be a direct Koala sale. ProductReview.com.au marks the Calm As discontinued, so a marketplace seller, reseller or private owner may set different return terms or offer no return at all. Get the terms in writing before purchase, including who pays collection or shipping, the condition required for a return and the deadline for notifying the seller.
During an eligible trial, test both firmness orientations, sleep in your normal positions and note pressure, alignment, heat and partner disturbance. Keep the mattress clean and protected according to the seller’s instructions; a return policy can be affected by damage or stains even when the product itself is still within the trial window.

What does the Koala Calm As warranty cover?
Koala’s official warranty document says the warranty begins on the date the purchaser receives the mattress and continues for 10 years. It is personal to the original purchaser, cannot be transferred and applies only while that purchaser is resident in Australia.
Coverage is limited to qualifying manufacturing or material defects. The document excludes normal wear and tear, normal softening and products bought from someone other than Koala. Those conditions matter greatly for a discontinued mattress: a second-hand buyer may possess a genuine product yet still lack warranty eligibility because the warranty is not transferable.
| Question | Warranty position |
|---|---|
| How long? | 10 years from the date the original purchaser received the mattress. |
| Who can claim? | The original purchaser, while resident in Australia. |
| What is covered? | Qualifying manufacturing or material defects. |
| What is excluded? | Normal wear and tear, normal softening and purchases made from someone other than Koala. |
| Can it transfer with resale? | No; the warranty is personal and non-transferable. |
Retain the original receipt, order confirmation and product details if you buy through an authorized channel. If a seller cannot explain how a warranty claim would be handled for that particular unit, treat the warranty as unavailable when comparing prices.

- The seller provides a verifiable business identity, physical contact details and a written return policy.
- The package is new, sealed or clearly described as used, with photographs that match the stated condition.
- The price is identified as a current seller price rather than copied from the historical CHOICE page.
- The seller explains whether the official 120-night trial applies to this transaction.

How should the Calm As be compared with other mattresses?
The most useful comparison is not another brand name but the trade-off between this mattress’s reversible all-foam design and the alternatives available today. Use the axes below when evaluating a replacement or a remaining Calm As listing.
| Comparison axis | What the Calm As offers | What to verify in an alternative |
|---|---|---|
| Firmness adjustability | Two orientations: medium-firm and firmer. | Whether the alternative has a genuine reversible or adjustable comfort system. |
| Construction | All foam, compressed in a box. | Whether a hybrid or spring design changes bounce, airflow or edge behavior. |
| Motion isolation | Minimal transfer reported by Tom’s Guide. | Independent testing or an in-home trial for partner disturbance. |
| Heat management | Good cooling reported in extended use. | Materials, bedroom temperature and a return period long enough to test warm nights. |
| Edge support | Decent, according to the review. | Perimeter construction and sitting stability. |
| Trial logistics | Official FAQ states a 120-night home trial; discontinued listings may differ. | Who accepts returns and who pays collection or shipping. |
| Warranty | 10 years for eligible original purchasers resident in Australia. | Transfer rules, exclusions and geographic limits. |
| Base compatibility | Ventilated support with slats no more than 7.5 cm apart; caution on adjustable bases. | Manufacturer spacing and articulation requirements. |
| Availability and price | Discontinued; CHOICE figures are historical. | Live inventory, seller legitimacy and the complete delivered cost. |
What problems do owner reports reveal?
Visible ProductReview.com.au feedback includes strong praise for comfort, reduced partner disturbance and the ability to switch between firmness sides. The same page also contains an individual account of back, neck and numbness complaints, followed by regret after the trial-return window was missed.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteThese accounts illustrate why a home trial and a clear return agreement matter, but they are not controlled testing or a representative failure rate. A mattress that feels supportive to one sleeper can create pressure or alignment problems for another. If you develop persistent pain, numbness or other symptoms, stop treating the mattress as a health solution and seek appropriate medical advice.
Who is the Koala Calm As best suited to?
Potentially good fit
- Couples who prioritize low motion transfer.
- Sleepers who want to choose between two nearby firmness levels.
- People who prefer an all-foam feel and want a mattress delivered compressed in a box.
- Buyers who can secure a genuine unit with enforceable trial or return terms.
Reasons to look elsewhere
- You need a very soft or very firm feel beyond the two reported orientations.
- You rely on an adjustable base for prolonged daily use.
- You require a transferable warranty for resale or relocation.
- You cannot verify the seller, condition or return policy of discontinued stock.
- You strongly prefer pronounced bounce or a rigid reinforced edge.
For most shoppers today, the decisive question is not whether the original design was competent; it is whether the specific unit can be bought with enough protection to test comfort and resolve defects.
Frequently Asked Questions
Does the 19-layer specification explain how the mattress will feel?
No. A layer count describes the number of component layers but not their thickness, density, zoning or how they interact under a particular body. Use the reversible-surface descriptions and an actual home trial rather than treating 19 layers as a quality score.
Can I judge comfort from a few minutes in a showroom or on collection day?
Not reliably. Pressure and alignment can change after a full night and after several consecutive nights, especially when you switch between the two orientations. A written trial or return agreement is more informative than a brief test.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →What should I check if a marketplace listing claims to include the original warranty?
Ask whether you would be the original purchaser under the written warranty terms and whether the seller can provide the original purchase record. The warranty document limits coverage to the original purchaser resident in Australia and excludes purchases made from someone other than the manufacturer.
Why might the historical CHOICE price differ from a listing I see now?
The CHOICE page does not show a publication year for its $1,700 listing or the $1,550 paid-after-sale figure. A current seller may charge more because stock is scarce, or less because the unit is used; neither price should be treated as an official present-day recommendation.
