Best online mattress retailers
Under UK law your rights sit with whoever sold you the mattress, which makes the choice of retailer a real decision rather than a price comparison.
I earn a commission if you buy through some links on this page. It never changes what I recommend, and I publish negative verdicts on brands I earn from. Editorial independence.
Most mattress advice treats the retailer as a way of getting a price. It is also the party you would claim against.
Under the Consumer Rights Act 2015, your statutory rights sit with the seller, not the manufacturer. Goods must be of satisfactory quality and last a reasonable length of time, and you have up to six years to bring a claim in England, Wales and Northern Ireland, five in Scotland.
That matters in this category specifically, because brands disappear. Eve went into administration in 2022, Brook + Wilde was liquidated in 2023, and Casper and Leesa have left the UK market entirely.
Buying direct means the brand is the retailer, so both risks are the same risk. Buying through an established third party splits them.
The picks
The pick, if you want one answer

Mattressman Review: Best specialist retailer
Varies
Scores 7.4. The genuine value of a specialist is that someone can tell you which other mattresses on the site share the same spring unit, which is the most useful question you can ask and one a brand's own site cannot answer.
Buy it if
You want a specialist that carries multiple brands and will answer specification questions.
Do not buy it if
You want the single lowest price on one named model.

Mattress Online Review: Best range and delivery
Varies
Scores 7.2. Old mattress removal has real cash value that never shows in a price comparison: a council bulky waste collection typically costs 20 to 40 pounds and usually requires getting it to the kerb yourself.
Buy it if
You want breadth of choice with old mattress removal available.
Do not buy it if
You want showroom testing.

John Lewis Mattress Review: Best for claiming against
Premium
A large, long-established retailer is the easiest party to claim against, and exclusive lines are the trade-off: you cannot price-check a model made for one retailer, so take the specification away rather than the name.
Buy it if
You want the most straightforward route if something goes wrong in year three.
Do not buy it if
Price is the deciding factor.

Time 4 Sleep Review: Best value online specialist
Varies
Scores 7.3. Worth applying the same checks to any online specialist: a UK company named in the footer, a stated returns process, and whether the sleep trial is the brand's or the retailer's.
Buy it if
You want specialist range at keener pricing.
Do not buy it if
You want the reassurance of a household-name retailer.

Origin Mattress Review UK: Best direct brand
From £265
The Hybrid Pro at £374 scores 8.4 here, the highest mattress score on this site. Buying direct concentrates the risk and buys you considerably more mattress, which is a trade worth making knowingly rather than accidentally.
Buy it if
You want maximum construction per pound and accept that brand and seller are the same party.
Do not buy it if
You want the risk split between two companies.

What the retailer is responsible for
| Issue | Who you go to |
|---|---|
| Faulty or not as described | The retailer, under the Consumer Rights Act 2015 |
| Did not last a reasonable time | The retailer. Up to six years in England, Wales and NI; five in Scotland. |
| Manufacturer guarantee claim | Usually the manufacturer, and the retailer often administers it |
| Sleep trial return | Whoever offered the trial. Frequently the brand, and only when buying direct. |
| Damaged in delivery | The retailer. Report it immediately and photograph it. |
Keep your proof of purchase and the date. After the first six months the burden of proof shifts to you, so photographs and an independent assessment help if you ever need to claim.
This is general information rather than legal advice, and Citizens Advice is the right starting point for a specific situation.
Buying direct is usually the only way to keep the trial
This is the most common way people lose the main reason they chose a brand.
Nectar's 365 night trial is the longest in the UK mainstream and applies buying direct. Silentnight's 60 night comfort exchange, which lets you change firmness rather than only return, also applies direct only.
Third party and marketplace listings frequently offer returns on an unused mattress only, which is a completely different product described in similar language. Once you have slept on it, it is yours.
So a third party being a few pounds cheaper is often a bad trade. Check whether the trial is the brand's or the retailer's before ordering.
Exclusive lines, and what to do about them
Large retailers sell a substantial proportion of exclusive lines: mattresses made for them under their own names, or exclusive specifications of a manufacturer's model.
That is not dishonest and it has a consequence. You cannot price-check the exact model anywhere, so a percentage off it cannot be evaluated.
The defence is to take the specification away rather than the name: depth, spring count for your size, whether the springs are pocketed or linked, and firmness. Those four travel between retailers where model names deliberately do not.
Four checks on any online retailer
A UK company named in the footer, checkable free at Companies House in two minutes.
A stated returns process: who collects, who pays, and what condition the mattress must be in. Almost all require it to be clean and undamaged, which is why a protector matters from the first night.
Old mattress removal, and whether it is included or chargeable.
Whether the specification is published at all. A retailer that lists depth, spring count and spring type is one you can compare. A retailer that lists adjectives is not.
What not to do
Buy through a third party to save a few pounds and lose the sleep trial.
Mistake a returns policy for a trial. If it says unused or unopened, it is not a trial.
Compare exclusive lines on price. Compare depth, spring count, spring type and firmness.
Buy from a site with no UK company named. Two minutes on Companies House.
Throw away the proof of purchase. After six months the burden of proof is yours.
Also considered, and why they are not here
A roundup is only as useful as what it leaves out, so here is what was assessed and rejected for this list.
| Product | Why it is not on the list |
|---|---|
| Dreams | A major chain with showrooms, which is genuinely useful for trying a mattress. Exclusive lines mean the specification matters more than the model name. |
| Bensons for Beds | Same category note: showroom access is the real benefit, and exclusive lines cannot be price-checked elsewhere. |
| Argos | Convenient and strong on returns logistics. The range is built to price points, so check depth and spring type rather than the description. |
| Soak and Sleep | Scores 7.7 and is strongest on bedding rather than mattresses, and it states fibre, weave and depth clearly, which most retailers do not. |
| Vesgantti | Sold primarily through a marketplace, where a 30 day window on unused stock is not a sleep trial. Establish who answers a warranty claim in year three. |
How this list is made, and who made it
Independence
No brand pays to appear on this site and no placement is sold. Some links earn a commission if you buy, which never changes a score, an order or a verdict. Several of the lowest scores here are on products that carry commission, and several recommendations carry none.
Who writes this. Kyle Klinkradt has worked in the mattress and bedding industry for over ten years across retail, distribution and brand partnerships, and has handled, sold or assessed products from every major UK bed-in-a-box brand. Every review on this site is written by one person, so the scores mean the same thing from page to page.
What the assessment is. Construction specifications against what they physically do: spring height and where in the mattress it sits, spring count for the size, gauge, whether the base is sprung or foam, foam density where it is published, comfort layer depth and material. Then the commercial terms that decide what you are actually buying: trial against returns policy, guarantee length against the company's UK trading history at Companies House, and the regulatory record.
What it is not. This is not a laboratory. I do not publish pressure-mapping data or claim to have slept eight years on every mattress here, because nobody has and pages that imply otherwise are not telling you the truth. Where a judgement rests on construction rather than long-term use, the review says so.
What gets a product removed. Leaving the UK market, a specification change that makes the review inaccurate, or a corrected fact. Brands that have withdrawn are kept on the site with the score removed rather than quietly deleted, because people still search for them.
See editorial independence, corrections and the author page.
How these were chosen
Every product here has its own review on this site with a score out of 10, and the score is a judgement rather than an average. Nothing appears in a list because it pays more.
A score is against the market, not against its own range. The cheapest mattress in a lineup is usually priced to make the model above it look reasonable, and the flagship of a budget range has risen into a bracket where better brands compete. Both are judged against what else you could buy for the money.
Everything listed can actually be bought in the UK. That is not a given: Casper withdrew in July 2020 and Leesa no longer sells here, and both still appear in current British roundups with affiliate links attached.
I do not pad the list. Where only three or four products genuinely qualify, there are three or four. A list of seven when the category contains four good ones is a list with three bad recommendations in it.
Prices move constantly. Judge the cash price on the day rather than any percentage beside it. See every review on this site or where the real savings are.
Questions people ask
Who do I claim against if my mattress fails?
The retailer who sold it to you. Under the Consumer Rights Act 2015 your statutory rights sit with the seller rather than the manufacturer, for up to six years in England, Wales and Northern Ireland and five in Scotland.
Is it better to buy a mattress direct or from a retailer?
Direct usually gives you more mattress per pound and keeps the sleep trial, which frequently applies to direct purchases only. Buying through an established third party splits the guarantee risk from the statutory risk, which matters with a young brand.
Why can I not find the same mattress at another retailer?
Because large retailers sell exclusive lines made for them under their own names. Take the specification away rather than the name: depth, spring count for your size, pocketed or linked springs, and firmness.
What should I check before buying from an online mattress retailer?
A UK company named in the footer, a stated returns process covering who collects and who pays, whether old mattress removal is included, and whether the specification is published at all rather than just adjectives.
