Our pick: EZE Hybrid Ultra Mattress

• Double
• Pocket sprung

We like: It's easy to turn over on

We don't like: The cover isn't removable for washing

EZE describes this mattress as a hybrid, but the large pocket spring core means we class it as pocket sprung, despite the foam layers. 

The foam layers won't suck you in, and it's breathable, so if you do tend to sweat or have hot flushes, the cover does a good job of wicking away moisture. 

Bought direct from EZE, it's delivered vacuum-packed in a box. Delivery is free, but there's no trial-night offer. You can, however, return it within 14 days of buying as part of the Consumer Contracts Regulations – just keep the original box. 

It comes with a 10-year warranty.

Typically on sale for £599, a double mattress is currently available for £569 at EZE.

Best mattress deals: £200-£299

Breasley Select PLUS Memory 1000 Pocket

• Hybrid
• Foam

We like: Despite the foam, it's not too warm to lie on

We don't like: It's bouncy

This mattress is available exclusively from online mattress retailer Mattress Next Day. It’s delivered rolled and vacuum-packed, direct to your door. You can't try it out in shops, and there's no sleep trial, but it has a five-year manufacturer's guarantee on the mattress core and a one-year guarantee on the cover.

It's a hybrid mattress that's claimed to offer 'tailored support' through a combination of pocket springs and 'body-moulding memory foam'.

This 21cm-thick double mattress includes a 14cm pocket sprung core over a shredded polyurethane base layer, and has a washable cover.

Our in-depth Breasley Select PLUS Memory 1000 Pocket review will help you decide whether this is the mattress deal for you. 

Best mattress deals: £300-£599

Jay-Be 2000 Hybrid E-Pocket Eco Truecore

• Double
• Pocket sprung

We like: It's not too bouncy

We don't like: The cover isn't removable for washing

This isn't the cheapest price we've seen for the Jay-Be 2000 Hybrid mattress, but it's still a good deal. 

The term ‘hybrid’ in this mattress's name is slightly confusing. Hybrid mattresses are usually a mix of pocket springs and foam layers, but there's no foam in this mattress. This is to conform to Jay-Be’s eco claims. Instead, it's made from pocket springs and layers of polyester: an 18.5cm pocket spring core, with a 2.5cm mini pocket spring core on top and several layers of polyester webbing.

Will the lack of foam mean it's less supportive?

Mattress Online Horizon Odyssey 800 Pocket Memory Mattress

• Double
• Hybrid

We like: It's easy to move around on

We don't like: It's a bit bouncy

The Mattress Online Horizon Odyssey 800 promises a ‘journey into comfort’. It's a hybrid mattress that combines a 14.5cm pocket spring core with two layers of foam (3cm above the pocket springs and 4cm below). Towards the surface that you sleep on, there’s a further 2cm section of memory foam.

It’s marketed as a medium mattress, but our independent tests rated it as 7.2 on a scale from 1 (very firm) to 10 (very soft), even though it may feel firm to touch.

But will this mattress stand the test of time, and will your sleep be out of this world?

Our Horizon Odyssey 800 Pocket Memory Mattress review reveals all.

Jay-Be Nettle Hybrid 2000

• Double
• Pocket sprung

We like: 100-night sleep trial and 10-year warranty included

We don't like: The cover is removable but it can't be washed

The name Nettle conjures up images of weeds stinging your shins rather than softness. However, Jay-Be claims the nettles and other plant-based fibres (such as cotton) used in this mattress provide natural comfort and exceptional breathability. 

The large 17.5cm pocket spring core and 3cm mini pocket spring means we class this double mattress as pocket sprung, rather than hybrid – despite the fibrous layers between the springs.

When it comes to firmness, our independent tests rated it as 6.5, on a scale of 1 (very firm) to 10 (very soft).

Silentnight Just Bliss

• Double
• Pocket sprung

We like: The 60-night sleep trial

We don't like: The cover isn't removable for washing

Not quite sure if you want a foam or pocket sprung mattress? Silentnight's Just Bliss double mattress combines a large pocket sprung core with layers of gel-infused foam, which should provide you with support and a bit of pressure relief for an aching back.

Our independent tests for firmness gave this mattress a 5.4 score on a scale of 1 (very firm) to 10 (very soft). It feels cold to lie on, so it's a good choice if you tend to sweat at night. 

But will it give you all-round body support and last as long as you'd expect?

Sleepsoul Space Orthopaedic Cool Gel

• Double
• Pocket sprung

We like: It's easy to move around on

We don't like: It's a bit bouncy

If you experience back pain, you may be swayed by Sleepsoul’s marketing promise that the Space Orthopaedic Cool Gel mattress provides ‘an exceptional blend of orthopaedic support and luxurious comfort’.

It's comprised of several layers, including a mixture of pocket springs, foam and memory foam. Starting at the bottom, you’ll find a large 22cm micro pocket spring core, topped with a 2cm layer of standard foam, then another 8cm layer of pocket springs. This is topped off with several different layers of foam and memory foam, including a 2cm layer closest to the surface you sleep on, which Sleepsoul calls ‘cooling gel’.

Does this double mattress provide long-lasting back support?

Ergoflex 5G

• Double
• Memory foam

We like: Feels cool to lie on

We don't like: It's heavy

On offer directly from the manufacturer, this is a bargain for those sleepers who value the light, floaty pressure relief provided by memory foam. Just bear in mind that this mattress type tends to 'cocoon' you, making it a bit harder to turn over on than a standard sprung mattress.

Constructed with a generous layer of memory foam on top, it also includes a waffled layer to improve ventilation and has vented mesh panels at the ends to reduce heat retention. All this helps to combat the overheating that can often be a drawback of memory foam products.    

It's only available online, direct from Ergoflex, with free delivery. You get a 30-night trial included and can return it for free if you don't like it. Ergoflex recommends sleeping on it for at least 21 nights to get used to it.

Read our full Ergoflex 5G mattress review to see if it will give you a good night's sleep.

You can get it for £498 using the offer code SAVE55 exclusively at Ergoflex.

Best mattress deals: £600 and up

Simba Hybrid

• Double
• Memory foam and springs

We like: 10-year warranty included

We don't like: Feels a bit bouncy

Introduced in 2023, the Simba Hybrid is an update to the Simba Original Hybrid. It's made in the UK and is delivered rolled up in a box. If, after 200 nights, you decide it's not for you, you can return it for free.

The mattress is composed of a 2.5cm layer of recycled foam, covered by 16cm pocket spring core, then 2cm standard polyurethane foam. There's another 2.5cm mini pocket spring layer on top, along with 2cm of Simbatex high-resistance polyurethane foam.

When it comes to firmness, our independent tests rated it as 6, on a scale of 1 (very firm) to 10 (very soft).

Read our Simba Hybrid mattress review to see how it fared in our tests.

The mattress is currently on sale at Land of Beds for £639.

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?

Let's face it, the mattress market is not known for being short of a deal or two. We see deals on mattresses every month, so our advice remains the same: if you need a new mattress, don't buy one purely because it's on sale. 

Don't be pressured into making a hasty decision. There are plenty of deals on throughout the year. 

Having said that, we have previously seen some good deals on mattresses over the Black Friday period. Although we've seen some priced lower at other times of the year, some mattresses are still available for a good price.

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.

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 is being taken to court by the Competitions and Markets Authority (CMA) regulator over its 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. 

Be warned, though – if you buy an Eve mattress via another retailer, such as Argos, the trial-nights offer might not apply.

As a guide, we've seen deals offering 20-30% off and up to 50%. 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.

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. 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 top five most popular Ikea mattresses to choose from there.

Simba mattress deals

Simba is another brand that's no stranger to a deal, and one that'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, as there can be conditions attached – such as a minimum spend or a discount that applies only to a particular mattress.

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.

• Argos
• Bensons for Beds
• Dreams
• Furniture Village
• John Lewis & Partners
• Mattress Online

To find the best shops to buy a mattress, we surveyed 1,800 Which? Connect panel members in October 2023. 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: 47% bought theirs in-store, while 53% shopped online.
