What makes Which? deals different
Retailers sometimes use misleading ‘was’ and ‘before’ prices to claim their deals are good. Media sites and artificial intelligence (AI) promote deals from retailers – but do they always check/verify them first? We don’t just take retailers’ word for it, we track actual market prices over six months. We share 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 six calendar months prior to publication. Not all retailers are included in our checks.

Jay-Be 2000 Hybrid E-Pocket Eco Truecore (130/0242)
Average price in the past six months: £329
Cheapest price in the past six months: £289*
- Double
- Pocket sprung
We like: Jay-Be says it contains no foam, a claim that forms part of its eco credentials
We don't like: We found the layers tricky to separate for recycling
Inside the Jay-Be 2000 Hybrid E-Pocket Eco Truecore (130/0242) you'll find an 18.5cm pocket spring topped with multiple layers of polyester webbing.
We rated it as 6.1 on our tension scale which allows us to compare the firmness of different mattresses, where one is very firm and 10, very soft.
There's only a five-year warranty with this mattress which is worth bearing in mind. The cover can't be removed for cleaning, so you'll have to factor that into general maintenance.
Read through our Jay-Be 2000 Hybrid E-Pocket Eco Truecore (130/0242) review to find out more about how this mattress did in our test lab.
Jay-Be Nettle Hybrid 2000 Mattress (324/7334)
Average price in the past six months: £455
Cheapest price in the past six months: £405*
- Double
- Pocket sprung
We like: Feels very cold to lie on
We don't like: Cover isn’t removable for washing
The name Nettle may conjure up memories of green weeds stinging your shins, rather than softness, but Jay-Be claims the nettles and other plant-based fibres used to create the Nettle Hybrid 2000 e-Pocket double mattress will provide natural comfort and exceptional breathability.
That all does mean that the cover can’t be removed for washing, however. Although the manufacturer says this mattress is naturally antibacterial.
It combines several layers, including a 17.5cm pocket spring core with a 3cm mini pocket spring above it plus several fibrous layers such as cotton, nettle-enriched fibres and ‘e-fibre’ in between. Jay-Be’s e-Fibre is made from recycled plastic bottles and the brand uses this material instead of foam. Jay-Be calls this mattress a hybrid, but we class it as a pocket sprung thanks to the large sprung core.
Read our Jay-Be Nettle Hybrid 2000 Mattress (324/7334) review to see how this mattress performed in our rigorous tests.
Dreams Dream Team Romsey Pocket Sprung
Average price in the past six months: £429
Cheapest price in the past six months: £299*
- Double
- Pocket sprung
We like: It has grips to help you move it around
We don't like: The layers are fiddly to separate for recycling
If you are looking for a cheap and firm mattress the Dream Team Romsey, currently on clearance at Dreams bedding chain store, is worth snapping up.
It has a 19.5cm pocket spring core with a 2cm layer of memory foam on top, closest to the surface that you sleep on. The cover is not removable for washing.
Dreams markets it as a firm to very firm mattress and we agree: it came in at 3.8 on our independently-tested mattress tension scale which runs from one (very firm) to 10 (very soft). It is one of the firmest mattresses we have tested.
Read through our Dreams Dream Team Romsey mattress review to find out more about how this mattress did in our test lab.
Mattress Online Luna Memory 4000 Pocket
Average price in the past six months: £502
Cheapest price in the past six months: £466*
- Double
- Hybrid
We like: It's easy to turn over on
We don't like: It's heavy – so it's very difficult to lift and manoeuvre
The Luna Memory 4000 Pocket mattress is a hybrid mattress that claims to give you the dual benefits of a generous (5cm) layer of motion-isolating, pressure-relieving memory foam, and the tailor-made support of individually responsive pocket springs.
This heavy double mattress is constructed with a main core of two 8.5cm micro pocket spring cores in between two standard polyurethane foam layers. It’s topped by a 5cm viscoelastic memory foam layer, which is a bit thicker than you often find in mattresses that include a memory foam layer.
It arrives rolled up in a bag and is exclusively available from Mattress Online, which offers a 10-year guarantee. Mattress Online's 60-night sleep trial promises an exchange for a different mattress from its website if you’re not satisfied.
Read our full Mattress Online Luna Memory 4000 Pocket review to find out if it's the one for you.
Simba Hybrid Inter
Average price in the past six months: £685
Cheapest price in the past six months: £484*
- Double
- Foam
We like: The long warranty and 200-night sleep trial
We don't like: The high memory effect means you sink into its surface, which some people might not like
The Simba Hybrid Inter mattress is the prestige version of the Simba Comfort range of hybrid mattresses. It combines a large foam core with a mini pocket spring layer and claims to offer an ‘enhanced sleep experience at a great price’.
Despite being labelled a hybrid, this mattress is mostly foam. There is a 19cm standard polyurethane foam (PU) core with a 2cm mini pocket spring core. This is topped by 2cm Simbatex HR PU foam, which Simba describes as graphite-infused with an open-cell structure that makes it more breathable and cooler than memory foam.
Simba offers a 200-night sleep trial, which means you can return it for free if you don’t like it. Simba's 10-year guarantee covers manufacturing faults.
Read our in-depth Simba Hybrid Inter review to see what kind of support, durability and pressure relief you should expect from this mattress.
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.
Panda Hybrid Bamboo
Average price in the past six months: £769
Cheapest price in the past six months: £589*
It's currently on sale at Mattress Online for £598 for a double mattress. Compare other retailers' prices below.
- Double
- Hybrid
We like: The washable cover
We don't like: It's relatively expensive when not on sale
If you worry about the health effects of sweat and skin cells accumulating in your mattress, the Panda Hybrid Bamboo mattress is designed to allay your worst nightmares. Panda claims that its bamboo cover is ‘hypoallergenic and naturally antibacterial, adding our signature layer of fresh, hygienic comfort to your sleep.’
It's a hybrid double mattress constructed from a 15.5cm pocket spring core sandwiched between two 2.5cm standard polyurethane foam layers, with a layer of 2.0cm viscoelastic memory foam topped by 2cm of high-resistance polyurethane foam (PU HR). It’s 24.5cm deep.
It is supplied rolled-up in a box. Panda offers a 10-year guarantee and a 100-night trial. You can return the mattress within this period if you decide it’s not right for you.
Our full Panda Hybrid Bamboo review reveals what our mattress lab testing discovered.
- The Panda Hybrid Bamboo Pro – which, the manufacturer claims, gives 'advanced orthopaedic-grade support' – is also on sale: SQUIRREL_TEXT_50023652
Sealy Posturepedic Elevate Blackwood (Firm)
Average price in the past six months: £900
Cheapest price in the past six months: £719*
- Double
- Open coil spring
We like: It's well-built
We don't like: The cover isn’t removable, or washable. Sealy suggests treating spills and stains as soon as possible with a sponge or damp cloth.
Sealy says its Posturepedic Elevate Blackwood double mattress will ‘soothe out pesky aches’, offering ‘blissful pressure relief’ thanks to its ‘unique spring system’.
At its core you’ll find 18cm of iron springs, below this there’s a layer of foam, and on top of the core you’ll find five different layers of foam including 2cm of memory foam nearest the surface where you sleep.
Marketed as a firm mattress, in our independent tests we ranked this mattress as 5.4 on a scale where one is the firmest and 10 the softest, so it’s more towards the middle of the scale

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 on sale, as there are plenty of discounts throughout the year. Some of the mattresses in this round-up have been available at the offer price for a while, but are still a good price.
'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.'
Not happy with your current mattress? You might be able to return it. Find out how to return a mattress. Can't return it? Find out how to get rid of your mattress, including options to recycle or donate it.
Will there be any good Black Friday mattress deals this year?
Jackie Gallego, Which? home content editor, says:
'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.'
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
The Emma Original mattress used to be one of the most popular models on the Which? website. But while it scored well in our lab tests overall, we're not currently recommending any Emma mattresses as Best Buys because the brand and the Competitions and Markets Authority (CMA) regulator settle court action over Emma's online sales practices.
Read our Emma mattress reviews.
Eve mattress deals
Another bed-in-a-box mattress brand, Eve is now owned by Bensons for Beds. You can find 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.
