Best mattress deals for 2021

Best mattress deals, including pocket spring, memory foam and hybrid mattresses from a range of brands, such as Emma, Eve, Simba and more, carefully selected by Which? mattress experts
Lisa Galliers

With so many deals around, it can be hard to know which ones are actually worth it, and when it's the best time to buy, especially when we are bombarded with discounts throughout the year. 

With the nights getting darker and the temperature starting to dip, now might be a good time to check whether your old mattress is giving you the best night's sleep. We'd recommend renewing your mattress after about eight to 10 years. 

And no matter if want a traditional pocket-sprung mattress, a memory foam mattress or maybe something in between, such as a hybrid mattress, we can help.

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

Black Friday mattress deals

Black Friday is on the horizon, so is it the best time to buy a cheap mattress? Not necessarily. A new mattress can be an expensive purchase, but it’s always worth shopping around to find a bargain.

While you’ll see a flurry of special offers and discounts as the annual Black Friday period approaches, not all Black Friday deals are good value. 

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

With this in mind, don't rush into buying anything just to make the most of the 'sale' price. Some brands seem to have deals on all the time. Big sales periods include Easter, Christmas , the new year and bank holidays. This year we've even seen deals tied into Valentine's Day, Father's Day, summer and even back-to-school time. 

But if you do need to buy around Black Friday time, then we'll be keeping an eye out and surfacing genuine deals on genuinely good mattresses on this page. So bookmark it.

For more tips on getting the best deal come the big day, see when is Black Friday.

Best mattress deals for October 2021

Our mattress experts have been keeping a close eye on the mattress deals popping up over the past months to bring you this round-up of the best mattress sales we've spotted on some of the most popular mattress brands searched for. 

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

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

1. Emma The Original mattress: 40% off

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

Emma's BIG Autumn sale has ended, so the 45% discount has dropped down to 40% off on its Emma Original mattress. This brings the usual price for a double (£699) down to £419.40. The downside is this current deal is for new customers only. This isn't the cheapest discounted price we've seen, (it works out about £35 more expensive), but it's not bad - if you're a new customer. However, Black Friday is around the corner, so it might be worth holding fire for a few more weeks. We usually see deals in the lead up, and not just limited to new customers. 

The mattress is made up of a 19cm foam core, with an additional 2cm layer of memory foam and 4cm layer of ordinary foam, and it's not too warm to lie on.

2. Otty Original Hybrid mattress: 40% off

Otty hybrid mattress
  • We like 100-night sleep trial, washable cover, average warmth to lie one
  • We don't like Bit of a memory effect when you lay on it, which some people may not like

You'll have seen this popular Otty mattress splashed about social media no doubt. Otty is currently offering around 35% off the Original Hybrid mattress, bringing the price down to £479.99 (from a stated price at the time of writing of £799.99).This isn't the highest discount we've seen, but, for less than £500, it's not a bad deal for this mattress.

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. Despite all the foam, it's not too warm to sleep on, but there is a very small memory effect.

3. Sealy Teramo 1400 mattress: 49% off

Sealy Teramo 1400 mattress
  • We like Doesn't need to be flipped, it's not too warm to lie on
  • We don't like It's heavy, known by multiple names which can be confusing

This Sealy pocket sprung mattress has been around for a fair few years, but if you're keen to step away from hybrid or foam mattresses it's worth a look. Also known as the Teramo 1400, Nostromo 1400 and Latex 1400, it can be hard to pin down the best deal.

It's been reduced slightly since we last checked, and it's now £607.94 for a double (RRP stated as £1,216 on mattressonline.co.uk). which is a good price for this mattress, and cheaper than it was on offer at the same retailer last month. Next still has it listed with £800 RRP, but 1-2 weeks delivery.

It's made up of a pocket sprung 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.

4. Eve The Original mattress: 30% off

Eve mattress_jun19 482271
  • We like It's not too warm to lie on, doesn't need to be turned, 100-night trial
  • We don't like You may sink into this mattress a little, which some may not like

This foam mattress from Eve Sleep is made up of an 18cm foam core, on top of which sits two 3cm layers of memory foam. Eve describes this mattress as neither too form or too soft. 

We've seen a flurry of deals on Eve Sleep mattresses recently, with a 25% off Original Hybrid just ended. It's now offering 30% off the Eve Original foam mattress, brining the cost down to £489 (from £699) for a double. Generally the discount on this mattress has been around the 30% mark, so it's a good time to buy.

5. Nectar memory foam mattress: 35% off

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

You'll no doubt have seen the Nectar mattress splashed about social media, and Nectar has another deal for you. At the moment, for a double, the price is £454.35 (down from £699). Unlike the recent offer, this price doesn't include any free gifts, but there are options to upgrade to a bundle.

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 warms 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?

How to get the best deals on specific mattress brands

Are you desperate for an Emma mattress, or have your eye on a Simba? Or do you want to swap your old mattress for a new memory foam mattress? It's worth keeping an eye out for mattress sales on your chosen brand's website. Social media is usually also a good place to spot a deal. 

There are plenty of deals and offers popping up throughout the year. But, be warned, the deals may not be offered on the particular mattress you want, if you have a specific one in mind, so check the T&Cs.  

Make sure you're prepared when the discounts start. Compare mattresses to find out which mattresses will be a dream and which ones could turn into an expensive nightmare, and don't forget mattress 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 deals on offer. Last Easter it was offering 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 out its website as a starting point, before comparing deals. Over the past year we've seen sales with up to 60% off.

Emma mattress deals

The Emma 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 three 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. We've seen discounts up to as much as 45%, so this is a good guide if you're after an Emma mattress but aren't sure when to take the plunge.

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 the Eve mattress 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. Check before you buy.

We've seen deals ranging from 20% to 30% off, but offers can be on certain mattresses only, so check the T&Cs before you buy.

Ikea mattress deals

You might not see Ikea mattresses discounted, but that's because these budget-friendly options are generally good value even when bought at full price. We've tested 13 Ikea mattresses, ranging from as little as £99 up to over £600, with an average price of just £284. Some of them even make the grade as a Best Buy.

Simba mattress deals

Simba mattresses arrive vacuum-packed in a box to your door, and the three mattresses currently in its range 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% off, but sometimes we've spotted there's some sort of condition, such as a minimum spend or a discount on a particular mattress.
