Mattress refund Australia: when your mattress doesn't match the description

You spent hundreds — maybe thousands — of dollars on a new mattress. The listing said "medium-firm memory foam", the salesperson confirmed it would suit a side sleeper, and the store's own "100-night comfort guarantee" made it sound like a risk-free purchase. Then the mattress arrived and it's nothing like what was described: it sleeps firm as a board, the materials feel nothing like memory foam, or the dimensions are off by enough to matter. Now the store is pointing you toward their comfort guarantee's fine print, which turns out to be riddled with exclusions.

Here's what you need to know: the store's comfort guarantee is a voluntary marketing promise layered on top of your legal rights — and your legal rights under the Australian Consumer Law (ACL) are considerably stronger than most mattress retailers will volunteer.

Quick answer

Whether you're entitled to a refund depends on what went wrong and how significant the gap is between what was described and what you received. The key variables are: whether the mattress fails to match its description (a consumer guarantee under section 56 of the ACL), whether it lacks acceptable quality for its price and type (section 54), and whether any failure is serious enough to be a "major failure" that gives you the right to choose your remedy.

In general terms, if a mattress is materially different from how it was described — for example, wrong materials, a clearly different firmness from the description used by the retailer, or the wrong size — consumer guarantees are likely to apply and you can seek a remedy. If the failure is major, you can reject the mattress for a refund or replacement (if the right to reject hasn't been lost), or keep it and claim compensation. If it's a non-major failure that can be remedied, the seller gets a first reasonable chance to repair, replace or refund; if it doesn't, you can have it fixed elsewhere and recover reasonable costs, or reject it (if the right to reject hasn't been lost). A store's "comfort guarantee" or "no change-of-mind returns" policy cannot remove these statutory rights.

What the law actually says

The ACL is Schedule 2 of the Competition and Consumer Act 2010. It applies automatically to goods a business supplies in trade or commerce where you acquired them as a consumer (section 3 of the ACL). A contract term (including fine print or a store policy that forms part of the contract) that tries to exclude, restrict or modify those statutory protections is void to that extent (section 64). For goods not of a kind ordinarily acquired for personal, domestic or household use, section 64A may let a contract limit liability (except the title-related guarantees in sections 51 to 53) to repair, replacement or their cost, unless you show relying on that limit isn't fair or reasonable. The consumer guarantees are the relevant mechanism here.

For a mattress dispute, three guarantees are most likely to be in play:

Section 56 — Goods must match their description. If the product listing, the swing tag, the salesperson's pitch, or the in-store display described the mattress in a particular way — "100% natural latex", "medium-firm", "queen 153 × 203 cm" — the mattress you receive must match that description. This guarantee applies regardless of whether you inspected the mattress before buying. If the mattress was supplied by reference to a description and the product delivered does not correspond with that description, the guarantee is breached.

Section 54 — Acceptable quality. Goods must be safe, durable, free from defects, acceptable in appearance, and fit for the purposes they're commonly bought for. A mattress that sags significantly after a few weeks of normal use, or that has a structural defect causing discomfort, is unlikely to be of acceptable quality: the test is what a reasonable consumer fully acquainted with its state and condition, including hidden defects, would regard as acceptable given its price and type.

Section 55 — Fitness for any disclosed purpose. If you told the salesperson what you needed — "I have a bad back and need firm lumbar support" or "I need something suitable for a heavy sleeper" — and you relied, reasonably, on their skill or judgment in recommending a product, the mattress must be reasonably fit for that purpose. The reliance element matters: you need to have made the purpose known and relied on the seller's recommendation, and the circumstances must have made that reliance reasonable.

When any of these guarantees is breached, your remedies sit in sections 259 to 263 of the ACL. The remedy available to you depends on whether the failure is "major" or not.

A major failure exists where a reasonable consumer fully acquainted with the nature and extent of the failure would not have bought the goods; the goods depart in one or more significant respects from their description; the goods are substantially unfit for their normal purpose, or unfit for a purpose you made known, and can't easily and within a reasonable time be made fit; or the goods are unsafe. Two or more smaller failures can together be major if a reasonable consumer fully acquainted with them, taken as a whole, wouldn't have bought the goods (section 260(2)). For a mattress, a significant mismatch in materials (e.g. described as latex, delivered as polyfoam) or a size error that means the mattress doesn't fit the bed frame would likely qualify.

Where there is a major failure, or a failure that can't be remedied, you — the consumer — choose: reject the goods (if the right to reject hasn't been lost under section 262) and take a refund or a replacement of the same type and similar value if one is reasonably available (section 263), or keep the goods and seek compensation for the reduction in value. Where the failure is not major and can be remedied, the seller gets the first reasonable opportunity to fix it, by repair, replacement or refund, within a reasonable time. If it refuses or doesn't do so within a reasonable time, you can have it fixed elsewhere and recover the reasonable cost, or reject the goods (subject to section 262).

When this applies (and when it doesn't)

The consumer guarantees apply when:

• You bought the mattress from a business — a retailer, a manufacturer's direct store, or an online seller operating in trade or commerce. Note that the ACL applies to businesses, and most sole traders selling goods will qualify as businesses even if they are individuals. The test is whether the person is acting in trade or commerce, not whether they have a shopfront.
• The mattress wasn't bought for re-supply, or to use up or transform in trade or commerce in production or manufacture, or in repairing or treating other goods or fixtures on land. Under section 3 of the ACL you're a consumer if the price was $100,000 or less or the goods are of a kind ordinarily acquired for personal, domestic or household use (either is enough), and those exclusions apply only to goods. Check how section 3 applies to your purchase.
• The failure relates to a defect, a mismatch with the description, or a fitness-for-purpose problem — not simply a change of mind.

Proof of purchase (a receipt, bank statement, email order confirmation, or any record linking you to the transaction) isn't a legal condition of the guarantees, but it is the evidence you'll need to show who supplied the mattress and when.

The guarantees are less likely to help you when:

• You simply changed your mind. If the mattress is exactly what was described and works as it should, but you've decided you'd prefer a different firmness, the ACL doesn't require the seller to take it back. The store's voluntary comfort guarantee is your only avenue in that scenario — and its terms will govern.
• The fault was disclosed before purchase. If the listing noted a manufacturing irregularity or the salesperson pointed out a cosmetic issue and you bought it anyway, you generally can't later claim on that specific defect.
• You caused the damage. Where you caused the problem and the mattress was damaged by abnormal use (stains, physical damage or misuse), the acceptable quality guarantee generally won't help.
• You bought from a private seller — for example, a second-hand mattress from an individual on a classifieds platform. The guarantees apply to supplies in trade or commerce, which includes most sole traders, but not a genuine one-off private sale.

One common point of confusion: the store's "comfort guarantee" or "sleep trial" is a separate, voluntary promise. It may give you more flexibility than the ACL (for example, allowing a change-of-mind return within 100 nights), or it may be more restrictive in some respects. But it sits alongside your ACL rights — it cannot take them away. If the mattress doesn't match its description, your ACL rights apply regardless of whether the comfort guarantee covers your situation.

What to do today

If you believe the mattress you received doesn't match what was described, or has a quality or fitness-for-purpose problem, here's a practical sequence:

1. Gather your documentation. Collect your receipt or order confirmation, any screenshots of the product listing, photos of the swing tag or in-store signage, and any written communications with the seller (emails, chat transcripts). If the salesperson made verbal representations, note them down with as much detail as you can recall — date, what was said, who said it.

2. Ask about a chargeback now. If you paid by card, ask your card issuer whether a chargeback is available; if you used buy now pay later, ask the provider about its dispute process. Both follow the card scheme's or provider's own time limits, not the ACL's, so check early.

3. Photograph the mattress. Take clear photos of the mattress as delivered, including any labels showing materials or specifications. If the issue is firmness or feel, that's harder to photograph — but photos of the product label compared to the advertised description can be very useful.

4. Compare the description to what arrived. Write out, specifically, what the listing or salesperson said, and what the mattress actually is. "Listed as 100% natural latex — label on mattress says 'polyurethane foam'" is a concrete, documentable mismatch. "Doesn't feel as comfortable as I expected" is much harder to make a case from.

5. Get an independent opinion if the cause is disputed. If the seller blames your use or disputes what the mattress is made of, a written report from an independent bedding specialist or other qualified expert, covering the cause and the cost of a fix, carries more weight than your own assessment.

6. Contact the seller in writing. Email is better than a phone call because it creates a record. Be specific: state the date of purchase, describe the mismatch or defect, identify the consumer guarantee you believe has been breached (description, acceptable quality, or fitness for purpose), and state what remedy you're seeking. Give a reasonable deadline — 14 days is common for goods disputes (a practical default, not an ACL requirement).

7. Keep the mattress. Don't dispose of it, and if possible don't use it further if you're making a quality or defect claim. The seller may want to inspect it, and a tribunal or court will want to know the condition of the goods.

What if the business refuses

Mattress retailers often push back hard on description-mismatch claims, particularly where the issue is firmness rather than a clearly measurable specification. If the seller refuses or doesn't respond within your deadline, you have several escalation options:

Your state or territory consumer protection body. It may help, for example by contacting the business or conciliating, if your complaint meets its criteria. Most expect you to have tried to resolve the matter with the business first, and eligibility rules vary by state and dispute type (in the ACT, for example, statutory conciliation applies only where the remedy you seek is worth $5,000 or less). These bodies don't make binding orders in ordinary consumer disputes and can't make the business settle. Contact details are at /agencies.

A tribunal or court with jurisdiction. In NSW, Victoria, Queensland, the ACT and the NT, a tribunal (NCAT, VCAT, QCAT, ACAT or NTCAT) hears many consumer claims within its limits; in Western Australia, South Australia and Tasmania, ordinary consumer claims go to the Magistrates Court. Jurisdiction depends on each forum's enabling legislation, the type of claim and the amount, so confirm the forum and its current thresholds on the official site before filing. You can usually run a claim without a lawyer, though some forums restrict legal representation (QCAT, for example, requires permission). Check current filing fees on the official site, and ask about fee exemptions, waivers or deferrals if cost is a concern. A well-documented description mismatch is the kind of claim these forums regularly assess. Our guide to choosing the right tribunal or court has more.

A demand letter before escalating. A properly written letter citing the relevant ACL sections often resolves disputes before they reach a tribunal or court. Many businesses would rather resolve the matter than defend it. The letter is also useful evidence if you do end up filing.

Common mistakes

A few patterns come up repeatedly in mattress and furniture disputes:

Relying only on the comfort guarantee. The store's sleep trial or comfort guarantee is a marketing tool, not your only legal protection. Its terms may exclude your situation — but your ACL rights exist independently. If the mattress doesn't match its description, the comfort guarantee's exclusions don't affect your statutory claim.

Framing a description mismatch as a comfort complaint. "It's not as comfortable as I expected" is a change-of-mind framing. "The product was described as medium-firm and the label confirms it is extra-firm" is a description mismatch. The second framing is much stronger. Be precise about what was described and what was delivered.

Accepting a store credit instead of a refund. If you're entitled to a refund after rejecting the mattress, you don't have to accept store credit: the supplier can't satisfy a refund by letting you acquire other goods from it (section 263(5)).

Not keeping records of verbal representations. If a salesperson told you the mattress was suitable for your needs, that conversation is potentially relevant to a fitness-for-purpose claim under section 55. Write it down as soon as possible — who said it, when, and what was said.

Assuming the ACL only covers defects, not mismatches. Section 56 is specifically about description. You don't need to show the mattress is broken or defective — you need to show it doesn't match what it was described as. A mattress that performs exactly as it was built to, but wasn't built to match the description, still breaches the guarantee.

Waiting too long. The ACL doesn't set a single fixed warranty-style expiry for consumer guarantee claims, but timing matters. Delay can make it harder to show the fault reflects a lack of acceptable quality (including durability), not wear or misuse. You also lose the right to reject goods if any of the four grounds in section 262 applies: the rejection period has ended (it runs from supply, not from when you noticed the fault, for as long as it would be reasonable to expect the failure to become apparent, given the type of goods, their likely use, and how long and how much they can reasonably be used); you have lost, destroyed or disposed of the goods; they were damaged after delivery for reasons unrelated to their condition when supplied; or they have been attached to or incorporated in real or personal property and can't be detached or isolated without damaging them. Deadlines for bringing a claim also apply under state and territory limitation laws and forum rules. Act as soon as you identify the problem.
