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 choose between a refund, a replacement, or keeping the mattress and seeking compensation. If it's a minor failure, the seller can choose to repair, replace, or refund. 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 sold by a business where the purchase falls within the ACL’s definition of a consumer transaction — and no contract clause, store policy, or fine print can opt you out of those statutory protections. 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 meet the acceptable quality standard a reasonable consumer would expect given the price and type of product.

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 it was reasonable to rely on their skill and judgment in recommending a product, the mattress must be fit for that purpose. The reliance element matters: you need to have made the purpose known, and the circumstances must have made it reasonable to trust the seller's recommendation.

When any of these guarantees is breached, your remedies sit in sections 259–261 of the ACL. The remedy available to you depends on whether the failure is "major" or not.

A major failure exists where the goods would not have been bought by a reasonable consumer who knew about the problem, the goods are substantially unfit for their normal purpose and can't easily be made fit, the goods differ significantly from their description, or the goods are unsafe. 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, you — the consumer — get to choose the remedy: a refund, a replacement, or keeping the goods and seeking compensation for the reduction in value. Where the failure is minor, the seller gets to choose the remedy, but must act within a reasonable time.

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 was not acquired for re-supply or for use in a manufacturing or repair process — the ACL's consumer definition covers personal and household use in the ordinary sense.
• The failure relates to a defect, a mismatch with the description, or a fitness-for-purpose problem — not simply a change of mind.
• You can show proof of purchase (receipt, bank statement, email order confirmation, or any record linking you to the transaction).

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. Stains, physical damage, or misuse that caused the problem won't be covered by a guarantee claim.
• You bought from a private seller — for example, a second-hand mattress from an individual on a classifieds platform. Consumer guarantees apply to businesses, not private sales.

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. 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.

3. 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.

4. 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.

5. 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 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's Fair Trading body. Each state and territory runs a free conciliation service. They contact the business on your behalf and attempt to broker a resolution. This step is often enough to move a stalled dispute — businesses tend to respond differently when a government body is involved. Full contact details for every state and territory are at /agencies.

Your state consumer tribunal. If conciliation doesn’t resolve the matter, you can often file a claim at NCAT (NSW), VCAT (Victoria), QCAT (Queensland), SAT (Western Australia), SACAT (South Australia), or the equivalent in your territory, typically under the state-applied version of the Australian Consumer Law or related state consumer legislation. Filing fees are modest, you don't need a lawyer, and the process is designed for ordinary consumers. Tribunals hear mattress and furniture disputes regularly — a well-documented description mismatch is the kind of claim they're well-equipped to assess. See our guide to state tribunals for help choosing the right one.

A demand letter before escalating. A properly written letter citing the relevant ACL sections often resolves disputes before they reach a tribunal. Businesses know that tribunals are predictable on consumer guarantee claims, and many 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 for a major failure, you don't have to accept a store credit. You can insist on an actual refund — for example, reversal to your original payment method where appropriate — rather than being forced to accept store credit. Store credit is only appropriate if you agree to it.

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 does not set a single fixed warranty-style expiry period for consumer guarantee claims, but timing matters. Delay can make it harder to show that a quality problem existed at the time of purchase rather than developing through use, and rejection rights may no longer be available if you've had the goods for an extended period. Act as soon as you identify the problem.
