Best Black Friday mattress deals

“Choose the mattress before November, write down what it costs in your size today, and buy in the sale only if the price beats that figure.”

Price your size before the sales start

A UK double is 135x190 and a king 150x200, and on this list the step from one to the other ranges from £20 on the Aspire Pocket+ 1000 Memory to £140 on the Emma Performance. For a wider shortlist in one size, see our best double mattresses and best king size mattresses.

Check what the saving is measured against

Simba’s undertakings to the Competition and Markets Authority, given after an investigation into its discount claims and countdown timers, signed in July 2024 and revised in September 2026, say a higher “was” price only counts once the mattress has sold at it “for a sufficient period of time and in sufficient volumes” (CMA case page). Three pricing styles on this list show why that test matters. Aspire prints a crossed-out price two and a half to three times the selling price next to every size of its 7000 Pillowtop. Nectar measures its percentages against an average of other brands’ prices. And on 26 October Emma’s headline offer added free products to a mattress order, which Emma’s UK site valued at up to £509, though a bundle is worth only what you would have paid for the extras. Our guide to Black Friday mattress sales covers the regulator’s and the advertising watchdog’s mattress cases in detail.

Put the trial ahead of the percentage

Buy online and the law gives you 14 days after delivery to cancel, under regulation 30 of the Consumer Contracts Regulations 2013. Some sellers refuse a mattress once its wrapping is off, pointing to the exception for sealed goods that cannot be returned for hygiene reasons (regulation 28). Yet in a 2019 case about exactly that, the EU Court of Justice ruled that a mattress whose protective film has been removed can still be sent back, because the seller can clean it for resale (Slewo judgment), a pre-Brexit ruling that remains part of UK law as assimilated case law. Aspire’s terms still exclude returns once its hygiene seal is broken, so a brand trial remains the safer protection. Emma and Simba give 200 nights with a refund and Nectar 365, while Silentnight’s 60 nights buy an exchange for another mattress rather than your money back. A refund trial protects the whole price, which no discount code can do.

Replace now, or wait another year?

The National Bed Federation and its consumer arm, the Sleep Council, recommend replacing a mattress every seven to eight years, roughly 20,000 hours of use, and their 2019 research put the average replacement at 6.9 years (Furniture News). “It would seem that a growing number of consumers are replacing their mattresses every seven years,” said Simon Williams, the federation’s marketing manager, when the figures were published. If yours is past that age and you wake up stiff, the sales are a sensible moment to replace it. If it is younger and only feels too firm or too warm, a topper may be the better buy.

Black Friday mattress topper deals

Toppers are discounted in the same sales and cost a fraction of a new mattress. The Emma Original Topper costs £219 in a double at its regular price, and Silentnight’s Hotel Collection topper, 10 cm deep, £67 in the same size. Our best mattress toppers ranking covers the rest, and our Black Friday pillow deals apply the same checks to pillows.
