The safety net you'll probably never use.
Every InstaMattress purchase is protected by our 100-Night Comfort Exchange. But here's the honest difference: other retailers need their trial, because their customers chose by guesswork. Yours was chosen by ComfortDNA™ — twenty verified scores, matched to how you actually sleep. The exchange is there. The evidence says you won't need it.
100 NIGHTS · £69 EXCHANGE · RE-MATCHED BY DATA, NOT GUESSWORK
A comfort trial is an apology for guesswork. Ours is a safety net behind evidence.
Think about what a 100-night trial admits: the retailer let you choose from a wall of mattresses with no real help, so they need a way to fix the inevitable mistakes. We work in the opposite order — the matching happens before you buy, against physically assessed data. When the choosing is done properly, the exchange becomes what it should always have been: a rarely-needed reassurance, not a revolving door.
Elsewhere: trial after a guess
- ◦Choose alone from endless near-identical options
- ◦Firmness labels from the marketing department
- ◦A few minutes lying down in a showroom — in your coat
- ◦The 100 nights exists to absorb the wrong choices
- ◦Exchange = back to the showroom to guess again
Here: exchange behind a match
- ✓ComfortDNA™ matches you first — against 20 physically assessed scores per mattress
- ✓Firmness measured by assessors, not claimed by brochures
- ✓Every match explained — you see why it fits before you buy
- ✓The 100 nights backs the evidence, rarely corrects it
- ✓Exchange = a Re-Match — your feedback updates your profile and the data chooses again
Four steps. One of them is unique to us.
Every mattress needs settling time — fillings adjust to you, and your body adjusts to it. Use a mattress protector from night one; it keeps your exchange valid.
If the comfort genuinely isn't working between nights 30 and 100, contact us. No interrogation, no hoops — one honest conversation about what's not right.
This is the part nobody else does. Your feedback — "too firm at the shoulder", "sleeping warm" — updates your profile, and ComfortDNA™ recalculates against every assessed score. Your replacement is chosen with more data than your original, not another guess.
We deliver your Re-Match and collect the original in the same visit for a single £69 fee, and the returned mattress is responsibly recycled — never resold.
Let's verify your order first
Enter your order number, the email address and the delivery postcode from your order. We'll check you're inside the 30–100 night exchange window.
Why £69, and why a fee at all?
Straight answer: two deliveries, a two-person collection, and responsible recycling of a king-size mattress cost real money. Retailers handle this three ways — hide it in higher prices, charge £95–£99, or pretend it's free and claw it back elsewhere. We charge the honest middle: £69, at cost, only if you exchange.
And because our matches are made on evidence, exchanges here are the exception — which is exactly why we don't need to price them like a revenue stream.
EXCHANGE FEES · UK RETAIL MARKET
Market fees observed across leading UK mattress retailers' published comfort-trial terms.
The terms, in plain English
No fine-print games — this is the whole policy.
- Who and when: available to the original purchaser on standalone mattresses bought from InstaMattress, between 30 and 100 nights from delivery. Proof of purchase required.
- One exchange per order. Your Re-Match replacement is not covered by a further exchange — which is why the Re-Match uses your feedback and every assessed score to get it right.
- Protector required: a mattress protector must be used from night one. For health and hygiene reasons we can't exchange a mattress that is stained, marked or damaged — it must be in clean, undamaged condition.
- The fee: £69, payable when your exchange is arranged. It covers collection of your original mattress, delivery of your replacement in the same visit, and responsible recycling. Returned mattresses are never resold.
- Same size; price difference settled fairly: your replacement must be the same size. If it's more expensive you pay the difference; if it's cheaper we refund the difference.
- Exclusions: clearance and ex-display mattresses (sold as seen), mattresses forming part of sofa beds or folding beds, and mattresses used commercially. UK addresses only.
- Your statutory rights are unaffected. This exchange is in addition to — never instead of — your legal rights, including your rights for faulty goods and your standard cancellation rights on unopened items.
The Comfort Exchange covers comfort preference. Faults and defects are handled separately under your guarantee and statutory rights, with no fee and no night-minimums.
Matched by evidence. Backed anyway.
Three minutes of questions. Twenty verified scores per mattress. One evidence-based match — protected by 100 nights, just in case.
