Mattress sales UK
UK mattress sales never really end, which is the single most useful thing to know before shopping one.
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.
Prices and codes move
Everything below describes how these discounts work rather than promising a number that will still be live when you read it. Percentages and thresholds change weekly. Check the cash price on the day and judge that, not the discount.
The sale never ends, and that is the point
Visit any of the big mattress-in-a-box brands on a random Tuesday in February and there will be a sale on. Visit again in June, and in October. The sale is not an event; it is the pricing.
That has one direct consequence for you. The discount carries no information. It is not telling you that now is a good moment, because there is no moment when it is absent.
So the question changes. Not is there a sale, but is this cash price good for what I am getting, against what else I could buy today.
The regulator has been active here. The Competition and Markets Authority secured undertakings from Simba in August 2024 requiring that was and now prices reflect genuine previous selling prices, and a consent order from Emma in May 2026 over urgency countdown timers, which were found unlawful. Emma separately won at trial in July 2026 on reference pricing, after which the CMA withdrew that guidance. The picture is live; the defence does not change either way.
What the calendar actually does
| Period | What really happens |
|---|---|
| January | Heavy promotion. Genuine clearance of discontinued lines, which is the real opportunity. |
| Spring bank holidays | Promotional noise. Cash prices rarely move much. |
| Summer | Quieter trading, so clearance stock and ex-display units surface. |
| Black Friday | Biggest headline percentages, smallest real change. Bedding and frames are the genuine wins. |
| Boxing Day into January | Warehouse clearing before new ranges. The best window for run-out models. |
The pattern: the moments that matter are when stock has to move, not when marketing says so. Discontinued lines, ex-display units and refurbished stock are cleared at the turn of the year and in the quiet summer months, and those are real reductions rather than repositioned list prices.
Three moments when something genuinely changes
1. A range is discontinued. Run-out stock is sold to clear, and a discontinued mattress is not a worse mattress. Check the guarantee still stands and that the seller will honour it, then buy it.
2. Refurbished stock appears. The largest genuine discount in the category. A refurbished Simba Hybrid Ultra has listed at around £699 against £1,749 new. Ask what the refurbishment involved and what warranty comes with it.
3. You become eligible for a scheme. Key worker, NHS, student, senior and forces discounts come off the everyday price and often stack with a live sale. Simba runs community hero discounts of up to 31 per cent. See key worker discounts.
Where waiting for a sale is pointless
Some brands price low permanently, so there is nothing to wait for.
Origin's Hybrid at £265 with up to 3,000 pocket springs, and the Hybrid Pro at £374, which scores 8.4 here. Silentnight's Sleep Now range from £169. Inofia's Elegant at around £210 for 27 centimetres and a spring core.
If one of those is the right mattress for you, buy it when you need it.
The thing worth more than any discount
Firmness is what buyers get wrong most often, and it cannot be judged in a week. So a genuine sleep trial is worth more than a percentage.
Nectar's 365 nights is the longest in the UK mainstream and applies buying direct. Silentnight's 60 night comfort exchange lets you change firmness rather than only return, and also applies direct only.
A cheaper mattress you cannot return is not cheaper. Check whether what you are offered is a sleep trial or a returns policy on an unused mattress, because those are different products described in similar language.
The one rule that beats every code
Ask whether the cash price is good for what you are getting. Not whether the discount is big. Not what the crossed-out number says.
If a mattress is worth the money you would hand over today, buy it. If it is only attractive because of the figure beside it, the discount is doing the persuading.
This matters more in mattresses than almost any other category, because several brands run high list prices against near-permanent discounting. A percentage off a price that has rarely been charged is not a saving.
The Competition and Markets Authority has been active here. It secured undertakings from Simba in August 2024 requiring that was and now prices reflect genuine previous selling prices, and a consent order from Emma in May 2026 over urgency countdown timers, which were found unlawful. Emma separately won at trial in July 2026 on reference pricing, after which the CMA withdrew that guidance. The regulatory picture is live and worth knowing; the practical defence does not change either way.
Questions people ask
When do mattresses go on sale in the UK?
Essentially always. Most brands discount continuously, so the sale is the pricing rather than an event. The moments that matter are when stock has to move: discontinued lines, ex-display and refurbished units, cleared at the turn of the year and in quiet summer months.
Is it worth waiting for a mattress sale?
Not for brands that price low permanently, such as Origin, Silentnight's entry range and Inofia. If one of those is right for you, buy it when you need it.
What is worth more than a mattress discount?
A genuine sleep trial. Firmness is what buyers get wrong most often and cannot be judged in a week, so a cheaper mattress you cannot return is not cheaper.
