Best mattress deals for April 2024

Each mattress listed below 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 any deal's T&Cs before buying.

All prices quoted are for a standard double mattress. See our guide to UK bed sizes for help with mattress sizes.

Our pick: Breasley Select Plus Memory 1000 Pocket

• Double
• Pocket sprung

We like: It's not too warm to lie on, removable machine-washable cover

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

Exclusive to online retailer MattressNextDay, the Breasley Select Plus Memory 1000 pocket is a pretty popular mattress on the Which? website. This already cheaper-than-average pocket sprung mattress is on offer for £339. MattressNextDay says this is a £90 saving on the full price. We've seen it on offer before, but it's still a good deal.

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. But it is bouncy and there's a slight memory effect.

Ikea Vesteröy firm 904.506.30

• Double
• Pocket sprung

We like: It feels cold to lie on, 10-year guarantee, it's really easy to turn over on

We don't like: It's bouncy

It's very rare that we get to feature an Ikea mattress in our deals page, but – like the Ikea Vågstranda firm 104.507.85 last month – this double mattress has had its online price lowered. You can snap up this already cheaper-than-average pocket sprung mattress for just £199 now, saving £30. This is another great Ikea bargain.

This is already a great-value mattress that combines a 15.5cm pocket spring core with two layers of foam on top.

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

It comes with a 10-year guarantee.

Silentnight Studio Gel 

• Double
• Pocket sprung

We like: Feels cold to lie on, five-year guarantee, 60-night sleep trial included

We don't like: The cover isn't removable so cleaning is a little trickier

Silentnight's Studio Gel mattress has been in the range for a while and you can also find it under it's alter ego, the Silentnight Just Bliss. But it's the Studio Gel which is on offer at Land of Beds at the moment, where you can snap this mattress up for a reasonable £350.  

It combines a 19cm pocket spring core with layers of foam on top, so it's perfect if you're a fan of springs but want a little extra padding to lie on.

It's marketed as medium firm and was ranked 5.4 in our assessments, on a scale from 1(very firm) to 10 (very soft).

Best mattress deals: £600 and up

Simba Hybrid mattress

• Double
• Memory foam and springs

We like: It's cool to lie on

We don't like: Feels a bit bouncy so bedfellows might feel each other moving

The Simba Hybrid is one of the most popular on our website. It wasn't on offer last month, but is now part of Simba's Easter sale – you can save 25% and get this hybrid for £614, which is a good price. Plus, you can get an additional 15% off if you sign up for the Simba newsletter. 

The latest iteration is constructed using layers of foam and pocket springs, and has a removable cover. It also uses Simbatex, which the manufacturer describes as graphite-infused foam with an open-cell structure, to make it more breathable and cooler than memory foam.

You can buy a double mattress direct from Simba for £614.

Emma Helix Hybrid mattress

• Double
• Memory foam and springs

We like: It's available in shops so you can try before you buy, average warmth to lie on so should suit most people

We don't like: We'd like more hand grips

The Helix is a hybrid mattress that's available from retailers such as Furniture Village, which means that unlike Emma’s usual bed-in-a-box offering, you can try it out in a shop before you buy.

If you can't get to the shops, some retailers offer a 100-night trial, during which period you can return it if you’re not happy.

Emma's no stranger to a mattress deal, and neither is Furniture Village – this mattress has been on offer for a while and is still available now for £649 at Furniture Village.

Eve Hybrid Duo Plus

• Double
• Memory foam and springs

We like: Really easy to turn over on, 40-night comfort guarantee, 8-year guarantee

We don't like: The cover is removable but confusingly, not washable

This Eve mattress is exclusive to Bensons for Beds. The Duo refers to the two layers of springs you'll find inside, sandwiched between layers of foam and memory foam.

Despite the layer of memory foam, this mattress feels cold to lie one, and there isn't much of a memory effect, either.

It's currently on offer with £100 off, meaning the double will set you back around £800. This isn't the cheapest we've seen it though.

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, and customers have recently reported issues with delivery. We've been in touch with Emma and the company has said it's dealing with the issues. 

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

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. Like rival mattress manufacturer Nectar, Eve offers a one-year 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 11 of them on our website, ranging from £99 up to around £689, with an average price of £361.

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.

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.
