Best mattress deals for August 2024

Each of these mattresses scores well in our independent testing, but may not be a Best Buy.

Prices and deals are correct at the time of writing, but deals can change or end at short notice. Always check deal T&Cs before buying.

All prices quoted are for a standard double mattress. See our guide to UK bed sizes to help you choose the right mattress for your bed.

Our pick: Breasley Select Plus Memory 1000 Pocket

Cheapest price in the last six months: £229

• Double
• Pocket sprung

We like: Removable machine-washable cover

We don't like: It's a bit bouncy and hard to rotate, no sleep trial

Exclusive to online retailer MattressNextDay, the Breasley Select Plus Memory 1000 Pocket is already cheaper than the average pocket sprung mattress. It's currently on offer for £249, which MattressNextDay says is a £70 saving on the full price. This isn't the cheapest we've seen it over the past six months, but it's still good value none the less. 

This 21cm-thick double mattress includes a 14cm pocket spring core over a shredded polyurethane base layer, covered by various layers of foam and memory foam. It's described as medium firm, but in our independent tests it was rated 7.2 on a scale from 1 (very firm) to 10 (very soft).

Despite the foam layers, it doesn't feel overly warm to lie on when you get into bed, so it should suit most people.

Best mattress deals: £200-£300

Ikea Vesteröy firm 904.506.30

• Double
• Pocket sprung

We like: The 10-year guarantee

We don't like: It's bouncy

It's very rare that we get to feature an Ikea mattress in our deals page, but you can still snap up this already cheaper-than-average pocket sprung mattress for just £199 now, saving £30.

It combines a 15.5cm pocket spring core with two layers of foam on top.

Based on our independent assessments, it's rated 4.2 on a scale of 1 (very firm) to 10 (very soft).

It comes with a 10-year guarantee.

Sleepsoul Cloud 800 Pocket Memory

• Double
• Pocket sprung

We like: It feels cool to sleep on

We don't like: No sleep trial offered

This mattress is delivered rolled and vacuum-packed, directly to your door. You can't try it out in shops, but it does come with a 10-year manufacturer guarantee.

The 29.5cm-thick double mattress includes a 26cm pocket spring core covered by three thin layers of standard polyurethane foam (2cm, 1.6cm and 1.4cm) with different densities.

It's pretty bouncy, so it may not be suitable for those with fidgety sleep partners.

Best mattress deals: £300-£599

Horizon Adventurer 1000

• Double
• Memory foam and springs

We like: It's breathable

We don't like: It's on the bouncy side

The Horizon Adventurer 1000 is a hybrid mattress combining pocket springs with a layer of memory foam.

The central 16cm core of micro-pocket springs is sandwiched between two 3cm foam layers, with a further 3cm section of memory foam towards the surface you sleep on, all held in place by a non-removable knitted cover.

It's a bit bouncy though, so may not be ideal for fidgety sleepers or their partners.

Silentnight Studio Memory

• Double
• Pocket sprung

We like: Easy to move around on

We don't like: No handles for moving or carrying

This mattress has a 16.5cm micro pocket spring layer surrounded by fibrous filling. On the surface closest to the body, there's a 2cm layer of memory foam, which Silentnight claims is 'ideal for sink-in snoozers and designed to gently hug you to sleep, moulding with the contours of your body.'

As the foam layer is only on one side of this mattress, it can’t be flipped over, but you may need to rotate it from head to foot to help keep it in the best condition.

It’s available on a 60-night comfort exchange programme and comes with a five-year guarantee, too.

Emma Premium

• Double
• Memory foam and springs

We like: It's breathable

We don't like: It's bouncy

Formerly known as the Original Hybrid, Emma says that this bed-in-a-box foam mattress has 'unrivalled temperature control and unbeatable comfort'. Its zoned pocket spring core is topped with layers of pressure-relieving memory foam, and there is a 200-night trial, a 10-year guarantee and ‘hassle-free returns’ on offer to tempt you.

The brand says this is a medium-firm mattress and our lab tests confirm this. In our independent firmness tests, this mattress ranked as 4.7, with 1 being the firmest and 10 the softest. 

But will this mattress support your spine sufficiently, or will it sag and soften over time?

EZE Hybrid Ultra

• Double
• Pocket sprung

We like: It's easy to turn over on

We don't like: There is no trial nights offer

The EZE Hybrid Ultra mattress may catch your eye with promises of long-lasting memory foam, pressure-relieving breathable layers and pocket springs to optimise support while you lie down, plus a soft-touch fabric cover. But we've seen it on offer before, so there's no need to panic buy. 

Although EZE describes it as a hybrid, the large pocket spring core means we class it as pocket sprung (despite the foam layers). It's marketed as a ‘soft mattress’. In our independent firmness assessments, we marked it as 7.1 firmness, on a scale from 1 (very firm) to 10 (very soft).

Delivery is free and there is a 10-year warranty. 

To see if it's worth buying now, check out our full EZE Hybrid Ultra Mattress review.

There's currently a 10% discount on all sizes at the EZE website, with the double reduced to £494.

Best mattress deals: £600 and up

Sleepeezee Fusion Pro

• Double
• Memory foam and springs

We like: Easy to lift and turn

We don't like: Polyester top can't be removed for washing

The Sleepeezee Fusion Pro has a pocket spring core, together with a layer of copper-infused memory foam that's claimed to mould to the contours of your body.

Internally, there’s a 6cm standard polyurethane foam base, topped with a 12cm pocket spring core. This is topped by a 3cm layer of high-resistance polyurethane foam and 2.8cm visco-elastic memory foam.

All Sleepeezee mattresses are suitable for use on bed frames with a slatted base, as long as the gaps are no more than 7cm.

So should you buy it? Check out our full Sleepeezee Fusion Pro review to find out.

Emma Diamond Hybrid

• Double
• Memory foam and springs

We like: The cover is removable for washing

We don't like: It could be easier to move about

The Emma Diamond mattress combines pocket springs and foam for ‘outstanding comfort and support’ according to the brand.

It's constructed from a combination of pocket springs and foam layers. Inside you’ll find a 13cm core of pocket springs, on top of which is a 6cm layer of foam and a separate 3cm layer of memory foam. Below the pocket spring core there’s a thinner layer (3cm) of foam.

The Emma Diamond Hybrid isn't sold at the manufacturer's own website – only in other shops. That may be more convenient for you, but does mean that the retailer might not have the same generous free trial that Emma provides directly. Double check to see if there's a trial available where you buy it from. It's still on offer, via both of the links below.

So should you buy it? Check out our full Emma Diamond Hybrid review to find out.

You can currently get this double mattress discounted to £667 at MyNextMattress and £749 at Land of Beds.

How to spot a good deal on a mattress

Lisa Galliers, Which? mattress expert, says:

'Don't panic about buying a mattress purely because it's on sale because there are plenty of discounts throughout the year. Some of the mattresses in this deals round-up have been available at the offer price for a while, but are still a good price for the mattress. 

'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 mattress for a fraction of the price of some.'

How to get the best deals on specific mattress brands

Whether you're after an Emma 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 chosen 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. Also, we've started to spot deals being swapped between the same mattress but with different cover options.  

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. And, 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. 

So 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. 

This bed-in-a-box brand delivers its rolled-up mattress direct to your door – it currently offers a trial of 200 nights. From what we've seen since we started this page, Emma offers a variety of deals available at different times, so keep an eye on the website and social media because you're bound to find a deal. The CMA is currently investigating Emma regarding its sales tactics. 

The best discount we've seen regularly is around 50%, although we've also previously seen even bigger savings, such as 65% off some mattresses. 

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. Eve 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. 

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 mattresses or 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 £361.

Not sure which one to go for? Head to the top five most popular Ikea mattresses to choose from there.

Simba mattress deals

Another brand that's no stranger to a deal, Simba mattresses arrive vacuum-packed in a box to your door. Simba 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 only applies to a particular mattress. The CMA is also currently investigating Simba regarding its sales tactics.

Are mattress sleep trials worth it? 

Sleep trials – commonly offered by online-only, bed-in-a-box mattress brands – allow you the 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 have back pain, for example, it could take quite 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 need to keep it for, if you need to use a mattress protector and what you need to do 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 they're offering one at all – might differ from those you get if you buy directly from the brand.
