When it comes to investing in the best mattress for your sleep style, you can easily find yourself spending anywhere from a few hundred to a few thousand pounds, so this is one purchase where a discount can add up to a big saving.
Using our extensive knowledge and our many, many hours spent testing mattresses, we've broken down everything you should know about where and when to shop to ensure you're getting the best mattress deals possible.

Mattress sale shopping advice
Of course, just because the price is good, that doesn't mean the mattress with the biggest discount is the right choice for you. So how do you decide on what's the best deal for your sleep preferences?
Our guide to the best mattresses on the market has the full lowdown on what to look out for before you shop, but if you can't test out your mattress in store before you buy (or even if you can, because a 5 minute lie down in a showroom is still very different to a full night's sleep) our top tip would be to look for a mattress that comes with a sleep trial.
Mattress retailers have become quite competitive about offering fairly lengthy sleep trials so you can fully test out your preference before you commit. 100-day+ trials are now fairly common, just make sure to check the small print before you shop for any terms and conditions.
When to shop mattress deals
Although good mattress discounts can crop up at any time of year, most retailers tend to follow a pattern when running promotions, with the biggest mattress discounts likely to fall at a few key times of year. We've collated a quick guide to the key dates to look out for below.
Bank Holiday mattress deals
Bank Holiday mattress deals also offer another opportunity to shop for less. From the end of June into July, and often throughout August, retailers may cut prices again. August Bank Holiday mattress deals can see particularly low prices, as the last UK Bank Holiday of the year is often a key time for consumer spending.
Amazon Prime Day mattress deals
It may not be the first place you'd think of looking for a mattress, but if you need an option that's both a low price and comes with super quick delivery then Amazon is well worth a try. Plus, Amazon Prime Day – the brand's yearly price-slashing event – can mean some great Prime Day mattress deals.
This years Prime Day will be on 8th and 9th October with significant discounts expected on the Simba Amazon storefront.
You need to be a Prime member to take advantage of the biggest discounts on Prime Day, so if you're not already a member you can sign up for Amazon Prime membership below. Usually, new Prime members can also access a free 30-day membership trial to test out its perks.
Black Friday and Cyber Monday mattress deals
Often hailed as the biggest shopping day of the year, Black Friday always falls on the last Friday of November, so the next time it will roll around is Friday 2 8th November 2025.
However, in recent years, the event has spread to encompass more than just one day, with retailers starting Black Friday discounting earlier and earlier so that a full Black Friday week or even month of discounts isn't uncommon.
In 2024, we saw some fantastic Black Friday and Cyber Monday mattress deals with nearly £200 off our top-rated Simba Hybrid Original mattress, 40% off our 5 starred Brook + Wilde Ultima mattress and up to 50% off at Emma and Dreams.
Boxing Day mattress deals
If you're done with the turkey and ready to nab a bargain, then you'll usually find some great Boxing Day mattress deals just after Christmas. In fact, in recent years, Boxing Day mattress deals have started well before Boxing Day itself, with stores increasingly offering discounts as soon as their pre-Christmas shipping dates have passed.
January mattress deals
Hang on a bit longer than Boxing Day, and you might find an even lower price if the mattress you have your eye on is included in the January mattress deals most brands offer.
Retailers know most of us are a strapped for cash in January thanks to Christmas spending, so there can be some good discounts on offer during this month to tempt us all into continuing to spend.
If a retailer wants to shift stock for the new season, then January mattress deals on end-of-line products can also get bigger as the month continues. However, if a mattress is being discounted because it's a discontinued line, then waiting does run the risk that the product may sell out before it drops to its lowest price.
FAQs
What is the best month to buy a mattress?
In our experience, November is the best month to buy a mattress. That's because November is the month when Black Friday mattress deals launch, which generally means discounts are the biggest we've seen all year.
Emma, Simba, Nectar, REM-Fit, Silentnight, Panda, and many more mattress retailers tend to launch extremely competitive Black Friday mattress sales in November.
And there's generally no need to wait for Black Friday itself (alway the last Friday of November), with Black Friday mattress deals now usually kicking off at the beginning of November.
Should you buy a mattress on Black Friday?
In our opinion, yes, Black Friday is a great time to buy a mattress. In our experience – and we've been reviewing the best mattresses on the market for many years now, so we regularly keep track of prices – Black Friday tends to see the best mattress deals and the lowest mattress prices of the year.
Mattress retailers are renowned for regularly slashing prices, with it sometimes seeming like there's never a sale not happening at the likes of Emma, Simba, Nectar and the like. However, in our experience, Black Friday week is when all of the mattress brands offer the biggest discounts of the year, competing with each other to offer the lowest prices around.
How do I get the best price on a new mattress?
The easiest way to find the best price on a new mattress is to wait for a mattress sale.
Although retailers can discount at any time of the year, most retailers tend to follow a pattern when running promotions, with the biggest mattress discounts likely to fall at a few key times of year; Black Friday at the end of November and the January sales.
If you can time your mattress purchase with one of these key trading periods then you may well be able to snap up a hefty discount and get your dream mattress for far less than its recommended retail price.
