Lisa Galliers

With so many deals around, it can be hard to know which ones are actually any good, and when is the best time to buy.

Is your mattress giving you the best night's sleep? If it's starting to sag or soften, think back to how long you've had it: you should renew yours every eight to 10 years. 

Whether you want traditional pocket springs, memory foam or maybe something in between, such as a hybrid mattress, we can help.

Our expert pick of the deals available this month, from some of the most popular brands, will help you find a mattress without paying over the odds. And, if you're not quite ready to buy, read on for our top deal-spotting tips for the future.

Best mattress deals in the sales 2021

A new mattress can be an expensive purchase. But there are so many deals across the year that it's always worth shopping around to find a bargain. There's no need to panic-buy just because you see one on sale and worry that you'll have to pay full price if you wait. 

Some brands seem to have deals on all the time. Big sales periods include Easter, Christmas, the new year and bank holidays. In 2021 we also saw deals tied into Valentine's Day, Father's Day, summer and even the back-to-school period. 

While you’ll have seen a flurry of special offers and discounts around the recent Black Friday and Cyber Monday period, not all of those deals were good value. 

We spotted the best offers for some brands during the August bank holiday weekend, beating the discounts offered in the recent Black Friday period. We also saw some deals offered around Easter 2021 that matched those promoted for Black Friday.

Our experts keep a close eye on the mattress deals popping up to bring you this round-up of the best offers we've spotted on some of the most popular brands that buyers searched for. 

Each mattress listed below has scored well in our independent tests. But to find the very best and make sure the one you choose is right for your specific needs, check our thorough reviews before you buy. 

Don't forget to check the small print if you're buying a mattress with a sleep trial offer. See how many nights are on offer and what you need to do to return it if it's not right for you.  

All prices below are for double mattresses. 

Emma The Original mattress: £349.50

The Emma Original mattress
  • Type: Foam
  • We like: Can be used on most bed bases, not overly warm, 200-night trial, doesn't need to be turned
  • We don't like: Only available online

The Emma Original is the most popular mattress on the Which? website and it's often on offer. It's currently in the Boxing Day sale with 50% off; 50% is the biggest discount we've seen for this Emma mattress, so if your heart is set on this one, now's the time to buy. 

The Emma Original is made up of a 19cm foam core, with an additional 2cm layer of memory foam and a 4cm layer of ordinary foam. Unlike some mattresses, it doesn't feel too warm when you lie on it.

Silentnight Now 7 Zone Memory Foam Mattress: now £233.99

  • Type: Memory Foam
  • We like: Lightweight
  • We don't like: It doesn't come with handles for turning

The Silentnight Now 7 Zone mattress (double size) is currently on offer for £199.99 on Amazon. It's a limited-time deal, so be quick if you want a cheap memory foam mattress. Though, if you would like to take advantage of Silentnight's 100-night trial, this mattress is also on sale at Wayfair for £233.99.

This double rolled mattress from Silentnight comes delivered in a vacuum-packed box, direct from the manufacturer to your door, and weighs just 17kg. It also has a 17cm foam core, with a token 2.4cm layer of memory foam on top.

Horizon Odyssey 800 Pocket Memory Mattress: now £297.46                                                                                                 


  • Type: Memory foam and pocket springs
  • We like: It's not too warm to lie on, doesn't need to be turned over
  • We don't like: Cover isn't removable for washing, softer than you may expect

The Horizon Odyssey 800 combines a 14.5cm pocket-spring core with two layers of foam on either side. It's almost identical to the Horizon Adventurer, but the quantity and the size of the pocket springs differs. Our independent tests rated it as 7.2 on a scale from 1 (very firm) to 10 (very soft): in other words, it's a softer mattress than many. It is also rated as cold to lie on, so suitable for those who sweat a lot at night. The MattressOnline website says this deal ends on 31 December.

Horizon Adventurer 1000 Pocket Memory Mattress: now £339.96

  • Type: Hybrid
  • We like: Doesn't need turning over (though does need rotating periodically)
  • We don't like: Could be easier to move 

This hybrid mattress combines pocket springs with foam and memory foam. There's 16cm of micro-pocket springs at the centre, between two foam layers. A further 3cm section of memory foam sits on top, on the surface you sleep on. It's marketed as medium-firm, which is about right: in our tests we ranked it as a 4.4, 1 being very firm and 10 being very soft. 

It weighs 31.5kg and isn't that easy to move, but does have handles. It's near-identical to the Horizon Odyssey 800 above but the number and size of the springs are different. The MattressOnline website says this deal ends Sunday 31 December.

Eve The Lighter Hybrid mattress: now £340

Eve mattress_jun19 482271
  • Type: Memory foam and springs
  • We like: 100-night sleep trial
  • We don't like: It could be easier to move around

This hybrid mattress from Eve Sleep is made up of a 10cm pocket-sprung core, on top of which sit two layers of foam. Eve describes it as more lightweight, but no less mighty, than its original hybrid mattress. 

Eve's price for the Lighter Hybrid has dropped once again. It's currently being offered in its winter sale at 40% off. Generally, the discounts we've seen from this bed-in-a-box manufacturer have been around the 30% mark. So the current deal at £340, further down from £369, is a good price. Eve Sleep says this offer ends on 31 December.

SleepSoul Space 2000 Pocket Sprung: now £344.95

  • Type: Pocket sprung
  • We like: Doesn't need to be flipped, cool to lie on
  • We don't like: It's heavy

If you're not a fan of foam mattresses, and want a pocket sprung one, the SleepSoul Space 2000 is still on offer. It's available at Happy Beds for a discount price of £374.99, but we've spotted the double size on sale for just £344.95 at MattressNextDay – which is a good deal.

Made up of a 24.5cm pocket sprung core, this has another layer of mini pocket springs on top, topped with a covering of foam on top. It weighs a hefty 43kg, but luckily it doesn't need to be turned over. It's listed as medium firm, but, in our independent tests, we ranked it as an 8, where 1 is the firmest and 10 the softest.

Horizon Discovery 1500 Pocket Memory Mattress: now £382.46                                                                                                                  

Dormeo S Plus Evolution mattress
  • Type: Memory foam and pocket springs 
  • We like: Doesn't need to be turned over, arrives rolled up to make it easier to move
  • We don't like: There's a high memory effect when you lay on it - which some may not like, softer than you may expect

The Horizon Discovery 1500 mattress is exclusive to MattressOnline. MattressOnline currently has 45% off the stated original price of £759. So it's now £382.46 for a double, which is a good deal.

This hybrid mattress combines a 2cm layer of mini pocket springs covered by layers of memory foam, and has a depth of 27cm. In our tests we rated this as average warmth to lie on, despite the memory foam layers which envelope you, so it should suit most people. It's marketed as medium firm, but in our independent tests we rated it as a 8.9 on a scale from 1 (very firm) to 10 (very soft).

Otty Aura mattress: now £384.99

  • Type: Hybrid
  • We like: 100-night sleep trial, washable cover, feels cool to sleep on
  • We don't like: Bit of a memory effect when you lay on it - which some people may not like

Otty says the Aura is its most affordable hybrid mattress. And it's currently on offer for £384.99 (from a stated full price of £699.99), which is cheaper than average for the hybrids we've tested.

Inside the Otty Aura you'll find a 16.5cm pocket spring core, surrounded by two layers of foam with extra memory foam layers on top that hels to contour to your body shape. Despite all the foam, it's cool to sleep on, so could be a good choice if you tend to get too warm at night. In our tests, we classified this as 5 for firmness on a scale where 1 is very firm and 10 is very soft.

Nectar memory foam mattress: now £411.95

Nectar mattress
  • Type: Memory foam
  • We like: 365-night trial offer, extra-long warranty
  • We don't like: Feels warm to sleep on

Nectar's current sale has 45% off this mattress's full price of £749, bringing it down to £411.95 for a double. This is the same price we saw during Black Friday and is one of the cheapest deals we've seen. 

Made up of a large 16.3cm foam core, topped with 3cm of memory foam and 2cm of foam topped off with a quilted cover, this foam mattress feel warm to lie on, so may not be the best choice if you prefer a cooler-feeling mattress. 

Is this the perfect mattress for all sleeping positions? To find out, read our full Nectar Sleep memory foam mattress review.

Otty Hybrid: now £479.99

Otty hybrid mattress
  • Type: Hybrid

  • We like: 100-night sleep trial, washable cover
  • We don't like: Bit of a memory effect when you lay on it, which some people may not like

Otty is currently offering 40% off the Original Hybrid mattress, bringing the price down to £479.99 (from a stated full price of £799.99 – although that's up from the £749.99 it was listed at in October). 45% off is the biggest discount we've seen on this mattress. Nevertheless, this isn't a bad deal.

There's a lot to this mattress – a 17cm core of micro pocket springs sandwiched between a 4cm foam layer beneath, plus a 3cm foam layer, on top of which sits 2cm of memory foam, closest to where you sleep.

Dormeo S Plus Evolution: now £499.99

Dormeo S Plus Evolution mattress
  • Type: Memory foam
  • We like: Doesn't feel too warm to lie on, 60-night trial offer, free delivery, 15-year warranty
  • We don't like: There is a memory effect when you lie on it

Dormeo's sale has the innovative Dormeo S Plus Evolution mattress on sale for £499.99 again. That's £500 off the full price of £999.99. At the moment, it's also offering 5% extra off if you sign up to its email. It's a great price for this innovative memory foam mattress.

This 'double' mattress is actually made up of two 'single' cores, both of which have a firm side and a soft side, and are held in place by the removable and washable mattress cover. This means you can flip the single-core mattresses individually to suit the preferences of both sleeping partners.

Simba Hybrid mattress: now £588.16

Simba Hybrid mattress
  • Type: Memory foam and springs
  • We like: 200-night trial, free returns, not too hot to sleep on
  • We don't like: Current offer is for new customers only

Simba's Hybrid mattress has gone up in price to £88.16 for a double. Simba says this is 36% off. It's not the cheapest we've seen this mattress, and this deal is for new customers only. Plus you'll need to spend over £300 to get this deal.

The Simba Hybrid is made up of several layers including a zoned support base, a mini pocket sprung layer and a foam topper. This bed-in-a-box mattress is delivered vacuum-packed in a box to your door and comes with a ‘risk-free’ 200-night trial. If you decide to return it, Simba offers a free return and won’t even ask you to get the mattress back in the box.

Rem-Fit 500 Ortho hybrid mattress: now £599.40

Rem-fit 500 ortho hybrid mattress
  • Type: Hybrid
  • We like: 100-night sleep trial, removable washable cover
  • We don't like: Mattress feels softer than claims, no handle grips 

This mattress is still on offer in the current Rem-Fit sale, and has been further reduced to 45% off. This brings the stated price of £999 down to £549.45. This is as low as it has been since before Black Friday.

This hybrid mattress combines a 16cm micro pocket-spring core with a 5cm layer of memory foam closest to the body. The manufacturer claims to have zoned the memory foam layer, varying its levels of density to deliver targeted support to different areas of the body.

Sealy Teramo 1400: now £595.15

  • Type: Pocket Sprung
  • We like: Doesn't need to be flipped, not too warm to lie on, five-year guarantee
  • We don't like: Heavy

This ever-popular Sealy pocket sprung mattress has been around for a fair few years, but, if you need a new mattress and are keen to step away from hybrid or foam mattresses, it's worth a look. It's also known as the Teramo 1400, Nostromo 1400 and Latex 1400, making it harder to pin down the best deal.

It's made up of a pocket spring core with a latex layer designed to improve comfort and support. This layer means the mattress doesn't need to be turned over, which is good, as it weighs 39kg. Sealy says this mattress is soft, and our independent firmness tests ranked it as an eight, where one is the firmest and 10 the softest.

You can buy a double for £595.15 at the moment: the same as its Black Friday price, which is a good deal. Just before Christmas it was on offer for £639.95. 

Stated full price on MattressOnline is £1,216, but we've spotted this mattress full price at Next for £800.

Emma Smart Hybrid: now £599

  • Type: Memory Foam and Springs
  • We like: Removable and washable cover 
  • We don't like: Emma's trial nights offer may not apply at all retailers so check before you buy 

We've spotted the Emma Smart Hybrid on offer for £599 (standard double) at Land of Beds. We've seen this mattress previously discounted to £799, so this is still a good deal price for this recently released Emma.

The Emma Smart Hybrid, called the Select in some retailers, is the first mattress from Emma to be available in-store. It's constructed from a number of layers including a 13cm spring core sandwiches between layers of foam and fabric. On the top of the spring core you’ll find a 3.5 cm layer of foam and another 2cm layer of ‘aqua gel’ foam on top of that, wrapped in a removable machine-washable cover.

Tempur Hybrid Supreme: now £1,499

Tempur hybrid supreme mattress
  • Type: Memory foam and springs
  • We like: Removable mattress cover, 10-year guarantee, not too warm to lie on
  • We don't like: You may find it softer than you're expecting

If you've got a bigger mattress budget that doesn't mean you should miss out on a deal. We've spotted the premium Tempur Hybrid Supreme double mattress on offer both direct from Tempur and Land of Beds. Tempur is offering it for £1,699, down from the list price of £1,899. Land of Beds' sale currently betters that, at £1,499. Buying it direct from Tempur does mean you'll get a 100 night-sleep trial (if it's your first time ordering).

How to get the best deals on specific mattress brands

Whether you're desperate for an Emma mattress, or want to swap your old one for a new memory foam mattress, 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, be warned, the deals may not be on the particular mattress you want, so check the T&Cs.  

Make sure you're prepared when the discounts start. Compare mattresses to find out which ones will be a dream and which ones could turn into an expensive nightmare – and don't forget retailers may have other sales happening in store.

Dormeo mattress deals

You may have spotted Dormeo mattresses on TV, or ads popping up on Facebook, and generally we've seen a range of different deals. You'll also spot free gifts such as pillows and duvets on top of existing sale 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. This means it's worth checking its website as a starting point before comparing deals. Over the past year, we've seen sales with up to 60% off.

Read our Dormeo mattress reviews

Emma mattress deals

The Emma Original mattress is one of the most popular reviews on the Which? website. This bed-in-a-box brand delivers its rolled-up mattresses direct to your door and offers a sleep trial (currently 200 nights). There are four mattresses in its range and, from what we've seen, a variety of deals are available during different months, so it's worth keeping an eye on the website or on social media. While we saw 50% off during Black Friday 2021, generally the biggest discount we've seen is 45%, so this is a good guide if you're after an Emma mattress but aren't sure when to take the plunge.

Read our Emma mattress reviews

Eve mattress deals

Eve is another bed-in-a-box mattress brand. Mattress deals can be found on the brand's Eve Sleep website or via some retailers, such as Next. Similar to Emma mattresses, Eve also offers trial nights so you can try the mattress. Currently there is a 100-night trial, and if you don't love it you can send it back free of charge. 

Be warned: if you buy an Eve mattress via another retailer, such as Argos, the Eve trial nights offer doesn't apply.

As a guide, we've seen deals ranging from 20% to 30% off. Check the T&Cs before you buy, though, as offers can be on certain mattresses only, or only if you spend above a particular amount, or for new customers only.

Ikea mattress deals

You might not see Ikea mattresses discounted, but that's because these budget-friendly options are generally good value even when at full price. We've got 11 of them, ranging from as little as £75 up to around £500, with an average price of just £227. Find out which ones are the top five most popular Ikea mattresses

Simba mattress deals

Simba mattresses arrive vacuum-packed in a box to your door, and the three in its range currently come with a 200-night trial. 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 between 25% and 35%. Black Friday and Cyber Monday 2021 saw some of the biggest discounts we've seen on these. But as a rule, anything around 30% to 35% is a good deal. Do check the T&Cs, though, as we've spotted there can be some sort of condition, such as a minimum spend or a discount on a particular mattress.
