What makes Which? deals different
Retailers sometimes use misleading ‘was’ or 'before’ prices to claim their deals are good. Media sites and artificial intelligence (AI) promote retailers' deals, but do they always check them first? We don’t just take the retailers’ word for it; we track actual market prices over six months. We share the cheapest and average calculations, and evaluate products against strict performance benchmarks. So you get good quality at honest prices.
*References to ‘average price' and 'cheapest price' are based on Which? market knowledge and information supplied by our partners. Prices are checked for the six calendar months prior to publication. Not all retailers are included in our checks.

EZE Hybrid Ultra mattress
Average price in the past six months: No data available
Cheapest price in the past six months: £539
EZE currently has its Hybrid Ultra mattress reduced to £539 from its £599 RRP.
- Double
- Pocket sprung
We like: It has a breathable soft touch cover
We don't like: There's no trial nights offer
The EZE Hybrid Ultra 800 mattress may catch your eye with promises of long-lasting memory foam, pressure-relieving breathable layers and pocket springs to optimise support. EZE describes this mattress as a hybrid, but the large pocket spring core means we class it as pocket sprung, despite its foam layers.
A large 25cm pocket sprung core makes up much of this mattress, that’s then topped with four different layers of foam. First there are two 1.5cm layers of standard foam, next is a 2cm layer of memory foam, followed by a 2cm layer of standard foam. The layers are all wrapped up in a soft-knit polyester cover. This isn't removable for washing.
It’s delivered vacuum packed in a box, which makes it much easier to get to the room of your choice. However, you’ll need to unwrap and unroll the mattress and leave it for a while to fully expand.
Find out how long this mattress will last without sagging and if it really will provide support and pressure relief in our EZE Hybrid Ultra Mattress review.

How to spot a good deal on a mattress
Lisa Galliers, Which? mattress expert, says:
'Don't rush to buy a mattress purely because it's in a Black Friday sale, as there are plenty of discounts throughout the year. Some of the mattresses in this round-up may have been available at the offer price before, but we think they're still a good price now.
'We sometimes notice retailers raising prices leading up to Black Friday, Boxing Day and other shopping events, so it can be tricky to work out what a good price actually is. To prep for the sales, use price comparison sites such as PriceRunner and PriceSpy to check historical price data, and follow this up with a quick Google search, as some retailers' price feeds aren't picked up by price-tracking sites.
'Where we have the data, we always add a cheapest and average price alongside our featured Black Friday mattress deals, to make things easier for you.
'We've also tested a range of good-value mattresses from brands that don't usually offer discounts – so if you want to keep costs down, you can still pick up a decent model for a fraction of the price of some.'

How to get the best deals on specific mattress brands
Whether you're after a new double mattress or want to swap your old mattress for a new memory foam one, it's worth keeping an eye out for sales on your favourite brand's website. Social media can also be a good place to spot a bargain.
Offers come and go throughout the year, but the deals might not be on the particular mattress you want, so check the T&Cs.
Make sure you're ready when the discounts start. Compare mattresses to find out which ones will be a dream and which could turn into an expensive nightmare – and don't forget that retailers might have other sales in-store.
Dormeo mattress deals
You might have spotted Dormeo mattresses on TV or via ads popping up on Facebook – we've seen a range of deals available, along with free gifts such as pillows and duvets on top of existing price reductions. Although its mattresses can be found through other retailers, in the past we've noticed that buying direct from Dormeo can sometimes save you a small amount in addition to any free gifts it may be offering.
We'd suggest you check the website as a starting point. We've seen discounts of up to 60% in the past.
Read our Dormeo mattress reviews.
Emma mattress deals
Emma mattresses score well in our lab tests, and many people own an Emma mattress, but we're not currently recommending any Emma mattresses as Best Buys because the brand and the Competitions and Markets Authority (CMA) regulator need to settle court action over Emma's online sales practices.
Read our Emma mattress reviews.
Eve mattress deals
Bed-in-a-box mattress brand, Eve, lists its deals on the Eve Sleep website, and at other retailers. It offers a 200-night sleep trial, so you can try out the mattress and, if you don't love it, send it back free of charge within 40 days.
As a guide, we've seen deals offering 20-30% off and up to as much as 50% on occasions. Check the T&Cs before you buy, as these discounts often apply only to certain models, if you spend above a particular amount or for new customers. Eve seems to swap deals fairly regularly between its mattresses.
Be warned, though – if you buy an Eve mattress via another retailer, such as Argos, the trial-nights offer might not apply.
Read our Eve mattress reviews.
Ikea mattress deals
You might not see Ikea mattresses on offer, but that's because they're generally good value for money at full price, and Ikea has recently lowered the price on a few popular mattresses. We've got 12 of them on our website, ranging from £99 up to around £689, with an average price of £312.
Not sure which one to go for? Head to the five most popular Ikea mattresses to narrow down your shortlist.
Read our Ikea mattress reviews.
Simba mattress deals
Simba is another brand that's often on offer. It's also been at the centre of a (now resolved) CMA investigation into sales tactics. Simba mattresses arrive vacuum-packed in a box to your door; the company offers free returns and its website states that it won’t ask you to get the mattress back in the box for the return journey.
We've spotted a range of deals from Simba offering 25-40% off. As a rule, 30-35% off is a good deal. Do check the T&Cs, though.
Read our Simba mattress reviews.
Are mattress sleep trials worth it?
Sleep trials – commonly offered by online-only, bed-in-a-box mattress brands – give you time to try out a mattress to see if it's the right one for you. If you don’t like it, you can return it within the trial period.
This can be useful if you're not sure which type of mattress will suit you best.
A long sleep trial lets you try your mattress during different seasons and gives you time to adjust, which is particularly important if you’re switching from springs to foam. If you experience back pain, for example, it could take a while to get used to a new mattress.
Not all sleep trials are the same, though, and some have strings attached.
If you're buying a mattress that offers a sleep trial, check the T&Cs first. See how many nights you'll be able to keep it for, whether you need to use a mattress protector and how to return it if it's not right for you.
Also, bear in mind that if you buy from a third-party retailer, the terms of a sleep trial – and whether it's offering one at all – might differ from those you get if you buy directly from the brand.
Read more about mattress sleep trials and find out which brand offers the longest.
Where's the best place to buy a mattress?
Retailers also offer their own deals throughout the year. We've listed some retailers below to get you started. Check T&Cs for deals before you buy.
To find the best shops to buy a mattress, we surveyed 1,800 Which? Connect panel members in October 2025. We asked how satisfied people were with their shopping experience from mattress retailers, both in-store and online.
Our latest survey of the best mattress brands rates mattress shops including Emma, Eve, Ikea and John Lewis on the quality and range of their products, as well as on advice and delivery. It also reveals that Which? members are divided on where they shopped for their mattresses: 48% bought theirs in-store, while 52% shopped online.
