Our pick: Soak&Sleep Zoned Hybrid Deep Memory Foam

Get this for just under £200 and save 30% (£85.50) on this mattress at Soak&Sleep

• Double
• Springs and foam

We like: It's very cheap

We don't like: It's slightly bouncy

This hybrid mattress combines a 17cm pocket spring core that’s sandwiched between a 2cm layer of foam below and above with a 4cm zone of memory foam on the side that you sleep on. It’s claimed that it includes 'shoulder support zones' using softer high gauge springs in this area while providing firmer low gauge springs for the rest of your body. 

The manufacturer markets it as a medium-firm mattress, with our lab tests scoring it as 4.9 on a scale from 1 (very firm) to 10 (very soft). This mattress will arrive tightly rolled in a vacuum pack and once unpacked it will need an hour or two to bounce back into shape. It comes with a ten-year guarantee.

Check out our full Soak&Sleep Zoned Hybrid Deep Memory Foam review to discover if it provides great support in all sleeping positions.  

Best mattress deals: £200-£299

SleepSoul Heaven

Average price in the past six months: £256
Cheapest price in the past six months: £208*

• Double
• Pocket springs and foam layers

We like: It's light and easy to rotate to even out wear and tear

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

Although the B&Q and Amazon deals might look like the best price its worth noting you will get a 60-night sleep trial on this mattress if you buy from Mattress Online UK that is not available from the two cheapest retailers.

The SleepSoul Heaven is a pocket sprung mattress covered with multiple layers of foam, including a pillow top, and layers of ‘coolgel’ foam. These are designed to help provide a supportive, cool,  comfy and breathable surface to lie on. 

It’s a boxed mattress, which arrives rolled up, making it much easier to get to the room of your choice. It's been on sale for quite a while, so you'd have to assume it must have been getting something right, or is it just the keen price that keeps customers coming back for more?

Best mattress deals: £300-£599

Memory Foam Warehouse Coolmax Hybrid

Average price in the past six months: £525
Cheapest price in the past six months: £390*

Get it for £390 at Memory Foam Warehouse.

• Double
• Mini pocket springs and memory layers

We like: It has a 100-night sleep trial

We don't like: It's rather bouncy

This is quite an unusual hybrid mattress as the foam layer is much thicker than the springs - usually they are the other way around. Its 17cm foam base has a 4cm layer of pocket springs above it, followed by a further 3cm section of memory foam on top, closest to the side you lie on. 

The manufacturer classes it as a medium-firm mattress and our tests agreed with this description. It’s also got a removable washable mattress cover, which can help you banish those allergy-causing dust mites from the bedroom.

Our full Memory Foam Warehouse Coolmax Hybrid review outlines the pros and cons of this mattress.

Otty Aura

Buy this mattress direct from Otty for £404 (or £475 with two Deluxe Pure pillows included).

• Double
• Hybrid

We like: Comes with a 100-night sleep trial

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

We've seen the Otty Aura on offer plenty of times, but at the moment, you can choose between a discount of up to 25% (to get the price referenced here) or two free Otty Deluxe Pure pillows instead. 

Interestingly, while this mattress is listed under a Black Friday exclusive banner, the fine print says this offer is ongoing and not time-limited.  Still, it's a good price for this hybrid mattress.

It's made from a combination of foam and springs. In our tests it was rated 'cold' to lie on, which means it won't trap heat around you. It's not too bouncy and the foam layers don't engulf you too much.

EZE Hybrid Ultra Mattress

Typically on sale for £599, a double mattress is currently available for £449 at EZE.

• 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.

Best mattress deals: £600 and up

Simba Hybrid

The Simba Hybrid is currently on sale for £589 at Land of Beds.

• Double
• Memory foam and springs

We like: A 10-year warranty is included

We don't like: It 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 you decide it's not for you, you can return it for free within the 200-night trial.

The mattress is composed of a 2.5cm layer of recycled foam, covered by 16cm pocket sprung 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. As for firmness, our independent tests rated it as 6, on a scale of 1 (very firm) to 10 (very soft).

Rem-Fit 600 Lux Elite Hybrid

Average price in the past six months: £869
Cheapest price in the past six months: £689*

Get it for £689 at Rem-fit when you use the code CYBER15. You'll also get two memory foam pillows and pillow protectors thrown in.

• Double
• Memory foam and springs

We like: The 15-year full replacement guarantee

We don't like: It's not the easiest to turn over on

Rem-Fit is doing something complicated with its current sale offer which it calls double savings. It's reduced this mattress from £899.99 to £809.99 and is offering a further discount if you apply a code.

REM-Fit’s 600 Lux Elite double mattress is a hybrid mattress featuring two layers of springs – a large core and a layer of micro springs – plus layers of pressure-relieving foam that the manufacturer says is breathable and helps to prevent overheating. 

Our tests revealed that it has some attributes of memory foam that some sleepers love and some sleepers dislike. So its worth reading our full review to see if it gives you the positives of good pressure relief or the negatives of being overwarm before you buy. 

Head to our Rem-fit 600 Lux Elite review to find out if it's a good choice for most sleepers.

Sealy Posturepedic Elevate Blackwood (Firm)

Average price in the past six months: £914
Cheapest price in the past six months: £610*

• Double
• Springs and foam

We like: It's good if you prefer a medium-firm tension 

We don't like: The spring construction is quite old-fashioned

This Sealy double mattress is available from a number of retailers, although its name is tweaked slightly in some shops. Depending on where you buy it from it might include a trial night offer - so check before you buy. 

There’s plenty going on under the cover of this mattress; at the 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. The cover isn’t removable, or washable.

Can this mattress provide proper support? Our Sealy Posturepedic Elevate Blackwood (Firm) review lays out the facts for you.

Panda Hybrid Bamboo Pro

Average price in the past six months: £1202
Cheapest price in the past six months: £888*

• Double
• Foam and springs

We like: The washable cover could help allergy sufferers keep dust mites at bay

We don't like: It's bouncy

This hybrid double mattress is constructed from a 13.5cm pocket spring core sandwiched between high-resistance polyurethane foam (PU HR) below and 2.7cm viscoelastic memory foam and topped by 4.2cm of PU HR. It’s 26.5cm deep.

It has a removable polyester and bamboo cover that can be easily unzipped and washed at up to 40°C. 

Panda describes this mattress as medium-firm.

Our review of the Panda Hybrid Bamboo Pro reveals how soft and supportive it really is.

Sealy Ultra Elevate Lunar

Buy for £1,599 at DFS (a saving of £400, according to the retailer). 

• Double
• Springs, foam and memory foam

We like: Good for front sleepers

We don't like: It's bouncy

One for people looking for bargains at the luxury end of the market, the Elevate Ultra Lunar is made by Sealy in the UK exclusively for DFS. DFS offers a seven-year manufacturer's guarantee and a 14-day returns policy on online purchases (but conditions apply). 

It is a luxurious 33.5cm thick and has a polyester and polypropylene top cover that can’t be removed. One for people who like a really soft bed our independent tests ranked it as 8.7, on a scale from 1 (very firm) to 10 (very soft).

Woolroom Rodmarton firm tension

• Double
• Springs, latex and natural fibres

We like: The 100-night sleep trial

We don't like: It's really heavy

Buy for £1,773 from Woolroom (a saving of £955, according to the brand). 

At full price this is very expensive mattress. But a lot of modern mattress technology has gone into this product, which also uses several more environmentally sustainable components than man-made foam and synthetic fabrics.

It has a 16cm layer of cotton calico-covered micro pocket springs providing its core, with a sandwich of two mini-springs and latex adding extra support. The plush pillowtop includes British wool and cotton padding layers. It’s 35cm thick and has a non-removable viscose and wool cover. 

Despite the firm tension implied in the name, our independent tests graded it as 7.1 on a scale from 1 (very hard) to 10 (very soft).  

Our full Woolroom Rodmarton firm tension review explains how you can expect it to change as it ages.

How to spot a good deal on a mattress

Lisa Galliers, Which? mattress expert, says:

'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 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.

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.
