The best mattress will give you a supportive, comfortable night’s sleep, without breaking the bank. That’s especially true over the Memorial Day weekend, now that all the leading brands have launched their sales. But there are a lot of mattresses to choose between, so how do you find exactly the right one? That’s where we can help.
We’ve spent hundreds of hours researching and reviewing the latest mattresses, sleeping on them ourselves, as well as collating feedback from thousands of users. We’ve ranked all the top-performing options here, in our best mattress guide, making sure there’s an option for everyone. No matter your budget or sleeping style, whether you need extra pressure relief or advanced cooling capabilities, or have a preference for a certain material – memory foam, innersprings, latex and so on – we’ve got you covered.
If you haven’t done it before, buying a mattress online is easy. Once you’ve found one you like the sound of, you can have it delivered to your home to try for yourself in just a few clicks. It’s a much more effective method for choosing the right mattress than a quick showroom test, and we’ve made sure that all our top picks come with at least a 100-night risk-free trial. If you choose one and decide it isn’t right, you’ll be refunded and the company will collect it.
The good news is that May is one of the best times of year for mattress deals . We’ve searched the Memorial Day mattress sales to bring you the lowest prices for all our top picks below. Here are the best mattresses for all budgets.
The best mattress in 2021 – as reviewed by experts
The popular Nectar Memory Foam mattress is tough to beat when it comes to sheer value for money. This all-foam, medium-firm, mattress in a box delivers superb comfort and support – and for a lot less than the competition. We tested it for two months and loved sleeping on it. The five layers of foam contour to your body, providing excellent pressure relief around your shoulders, hips and back, while also helping align your spine. We also found temperature regulation to be very good for a memory foam mattress. We didn’t overheat once at night, even during the hot summer months.
This mattress is a very good choice for couples. It absorbs motion well, so you won’t be disturbed by a restless partner. We found the edge support to be good too. We could sleep comfortably right up to the perimeter, which made it feel wider.
Where the Nectar Memory Foam mattress really stands out, of course, is value. Thanks to a permanent $400 discount on most sizes, it’s dramatically cheaper than the competition, undercutting Casper and Purple by a few hundred dollars – and comes with $399-worth of free gifts too. There’s also an industry-leading year-long trial, free shipping and returns, and a lifetime warranty, all of which makes it a very compelling proposition indeed.
Memory foam isn’t for everyone, so if you like the sound of the Nectar mattress (and want the free gifts) but prefer to sleep on top of your mattress rather than sinking into it, we’d recommend the hybrid DreamCloud at number seven. And if you have a bigger budget to play with, the luxury innerspring Saatva Classic mattress at number two is outstanding. But Nectar beats them all on value for money: if you’re looking for an extremely comfortable mattress and want the most bang for your buck, it’s easily the best mattress around.
Nectar Memorial Day sale: Save $400 + get $399 of free gifts
From $499 – Nectar tends to run the same offer all year round, and it’s the same this Memorial Day. Still, it’s the best mattress deal you’ll find anywhere, with up to a $400 discount, plus two pillows, a free mattress protector and sheet set worth $399 added to your order. Fantastic.
The flagship Saatva Classic is a premium, hotel-quality mattress from luxury online brand Saatva. On quality alone, it’s the best mattress we’ve tested so far – the only reason it doesn’t take the top spot in our guide is the $1,000-plus price tag. But if you have the budget, this high-end hybrid innerspring is a sound investment and delivers a stunning night’s sleep.
One big selling point is how customizable it is. The Saatva Classic comes in soft, medium and firm versions, and your choice of height: 11.5 or 14.5 inches. We tested the 11.5-inch luxury firm option and were impressed: premium, eco-friendly foams and a plush pillow top provide soft cushioning, while a super-durable, dual steel coil system delivers exceptional support for your lower back. The Saatva Classic has been awarded a Seal of Approval from the Congress of Chiropractic State Associations, and the luxury firm option is a great choice for anyone suffering from back pain.
We love how buoyant this mattress is: you won’t sink into it while you sleep, which is good news for anyone who tends to overheat at night – we consistently slept cool. (If you do want the ‘hugging’ sensation that comes with memory foam, you’ll be better off with the Nectar above, or the Cocoon Chill at number six.) It’s also durable. Some of our reviewers are one year in now, and their mattress is still performing well. Edge support, in particular, is as firm as it was 12 months ago, and we’d recommend it for anyone who struggles to get in and out of bed.
All this quality comes at a cost, of course. The Saatva Classic isn’t the cheapest option in our best mattress guide – but it is very good value for a premium mattress, undercutting its luxury hybrid rivals by up to a few hundred dollars. Plus it comes with free white glove delivery to the room of your choice, and a 180-night trial. If you’re looking for pure luxury at an affordable price, this is it.
Saatva Memorial Day sale: save $225 when you spend $1,000
From $849 – Saatva’s Memorial Day sale officially gives you a $200 discount… But we can beat that, with a $225 discount – that’s better than Black Friday. It means you can get a queen size Saatva Classic for $1,274, down from $1,499, while a king costs $1,674 (was $1,899). Deal ends: 31 May View Deal
The Tuft & Needle Original mattress is a very good budget mattress. It isn’t the cheapest in our guide – that’s the Zinus Green Tea Memory Foam mattress at number 10 – but when it comes to balancing performance with price, this no-frills mattress has a lot to offer.
Made from two layers of foam, the Tuft & Needle Original is a surprisingly supportive medium-firm mattress. There’s no memory foam here, so you don’t get the contouring you’d expect from the other options in our best mattress guide, but we found T&N’s adaptive foam to be responsive, with good cushioning and pressure relief for back and side sleeping.
Stomach sleeping wasn’t quite as comfortable, however – we’d have liked a little more support. Also, it’s worth noting that despite the mattress’s various cooling features (graphite and cooling gel), we woke up in a sweat a few times. If you’re prone to overheating and need a budget mattress, we’d recommend a hybrid instead, such as the Allswell mattress at number nine.
Still, despite a few complaints about indents appearing after a year or so of use, the Tuft & Needle Original mattress has racked up over 40,000 positive user reviews across the T&N site, Amazon, Google and Yelp. And that’s because it’s good at the basics. If you can do without the bells and whistles of more premium options, it’s a top choice for a budget mattress.
Tuft & Needle Memorial Day sale: save 15% on the Original
From $382.50 – There’s a 15% discount on the T&N Original mattress for Memorial Day, which takes the price of a twin down to £$382.50, or a queen from $695 to $590.75. There’s also up to 20% off bed frames and sheets, with a 10% discount on duvets, pillows and more too. Deal ends: 31 MayView Deal
The Purple mattress offers a premium night’s sleep at a mid-range price. Made by one of the most innovative mattress brands in the US, it stands out thanks to its unique ‘Purple grid’ technology. This patented material is a dynamic, hyper-elastic gel-like foam that instantly adapts and flexes under your body to deliver tailored support right where you need it.
We gave the Purple mattress high marks across the board when we reviewed it. It was easy to order, and when it arrived it was fairly simple for two people to unpack and unroll, with no off gassing or plastic smell. It does feel different to other foam mattresses: the gel grid instantly responds to movement, cradling pressure points and aligning your spine, and springing back into place when you adjust your position. We felt like we were floating, cushioned by the soft, plush top, while also being supported by the surprisingly firm durable base layers.
The Purple mattress is a particularly good choice for couples – the grid does an excellent job of isolating movement, so you won’t be disturbed by tossing and turning. It’s also a great option for anyone who overheats at night. There are over 2,800 open air channels to allow cooling throughout the mattress, plus breathable foams and a soft flex cover help prevent heat from building up. Not everyone gets on with the Purple grid – some people report that the unique soft but supportive feel takes a while to get used to. We say it’s totally worth the wait.
Purple Memorial Day sale: up to $300 off the Purple + bundle
From $599 – Purple’s continuing to cut $100 off its flagship Purple mattress – but you can bump the saving up to $300 if you add a bundle to your order. There are a few different options to choose between, each adding different products to give you a different saving, so you can choose the one you prefer.View Deal
While all the top picks in our best mattress guide are well-suited to side sleepers, only one has been specifically designed for people who prefer this sleeping position: the Helix Midnight. This medium-firm hybrid is the brand’s most popular mattress, with five layers that are designed to support your body’s contours and cushion your shoulders and hips while you’re sleeping on your side. Soothing memory foam and dynamic polyfoam hug your body and relieve pressure, while hundreds of individual coils cradle your body, provide extra support, and limit motion transfer.
We particularly like Helix as a brand because aside from making brilliant mattresses, the company also has one of the best websites for buying a mattress online. If you’re doing this for the first time, you’ll find a handy sleep quiz on the site that will help you decide whether the Helix Midnight is the best mattress for your sleeping style and preferences, or whether you (and your partner) might be better suited to another model from Helix’s excellent range.
Helix Memorial Day sale: save up to $150 + 2 free pillows
From $599 – There’s up to a $150 discount on the Midnight mattress at Helix for Memorial Day. If you spend $1,250 or more (ie if you buy a king or CA king size) you’ll save $150; for all smaller sizes there’s a $100 discount. Both options add two free pillows to your order.View Deal
The Cocoon Chill Memory Foam is a 10-inch deep memory foam mattress made by industry giant and household name Sealy. Designed to adapt to your body to provide tailored support all over, this medium-firm mattress has three different foam layers, with luxury memory foam for deep contouring; responsive comfort foam to reduce motion transfer and prevent you sinking into the mattress; and a durable support layer.
But where the Cocoon Chill Memory Foam mattress really stands out is its high-end stretch-knit cooling cover. It’s infused with phase-change material, which absorbs and dissipates heat from your body and helps you stay sweat free all night. During the entire period in which we tested the Cocoon Chill, we didn’t overheat once – even our hot-sleeping reviewer didn’t wake up in a sweat. This feature, alone, elevates this mattress above its all-foam rivals.
The Cocoon Chill Memory Foam mattress should be well-suited to most body types and sleeping positions. We found it especially comfortable for side sleeping, and it’s a particularly good option for hot sleepers who want the ‘hug’ of memory foam.
Edge support could be better, as is often the case with foam mattresses. But overall we highly recommend the Cocoon Chill Memory Foam, with top marks for its comfort and cooling abilities, and superior marks for its motion isolation and lack of sound. The price, too, is very appealing: it’s permanently sold with a 35% discount – making it extremely competitive. If you’re looking for an affordable, medium-firm memory foam mattress, there’s a lot to like about the Cocoon Chill.
Cocoon by Sealy Memorial Day sale: save 35% + get free pillows and sheets
From $469 – Sealy is still running its biggest-ever sale: it isn’t a special offer for Memorial Day, but it is great value with 35% off the Cocoon Chill Memory Foam mattress, plus two free pillows and a sheet set worth up to $199 thrown in. Bargain.View Deal
If you liked the sound of the Nectar mattress at number one but don’t want an all-foam option, we highly recommend trying the DreamCloud. This popular, luxury hybrid mattress is sold at a lower-mid-range price: it isn’t quite as plush as the premium Saatva Classic, but it’s a few hundred dollars cheaper and comes with free pillows (plus free sheets and a mattress protector in the current sale too).
At 14 inches, this medium-firm mattress is one of the tallest in our guide, and it comes packed with five generous layers that offer firm, responsive support as well as deep, soft cushioning.
The core of the mattress consists of a layer of individually wrapped coils. These provide custom relief by adapting to your body shape, and give the DreamCloud a traditional innerspring mattress feel, with more bounce than you’ll get from an all-foam option. The springs also boost airflow, helping dissipate heat during the night. Above these sit a gel memory foam layer, which is designed to contour to your body, cradling your shoulders, hips and other pressure points. There’s also a cooling, quilted cashmere cover on top.
Existing users love it: the DreamCloud averages a full five stars from almost 3,000 reviews on the DreamCloud website, and 4.2 out of 5 on independent review site TrustPilot, from a smaller pool of 800 users. The majority of reviewers comment on how comfortable the mattress is, how much better they sleep now, and how good the customer service is at DreamCloud. A few users say that edge support could be a little better for sitting on the side of the bed.
Bear in mind that the DreamCloud is heavier than some other mattresses (a queen size weighs 85lbs compared to Nectar’s 74lbs, while a king size weighs 107lbs) so you’ll want two people to move it. Alternatively, in non-covid times you can pay an extra $149 for white glove delivery. We love that the DreamCloud comes with a huge 365-night trial and forever warranty. Shipping and returns are also free, which makes testing this mattress at home incredibly easy.
DreamCloud Memorial Day sale: $200 off + $399 of free gifts
From $699 – DreamCloud is offering a $200 discount on its flagship mattress for Memorial Day, with $399-worth of free gifts added to your order. That’s almost as good value as the Nectar offer – and makes this luxury hybrid very appealing indeed. With a year-long trial and forever warranty, it’s worth considering.View Deal
The Avocado Green mattress is the best organic mattress you can buy. Made from non-toxic, eco-friendly materials, this high-quality hybrid mattress offers a luxurious, gentle-but-firm sleeping environment, and has outstanding green credentials.
Customers certainly love it. The Avocado Green mattress boasts an average score of 4.7 out of 5 from over 12,000 reviews on the Avocado website. Many people praise how comfortable it is – and some say their back pain has disappeared. There are two different versions to choose between: standard, which is 11 inches deep; or pillow top, which adds an extra two inches of luxury support.
Both are made from premium, natural materials, including ethically sourced GOLS organic certified latex, wool, and cotton (GOLS is a global textile processing standard for organic fibers). There are also 1,414 pocketed coils to distribute your weight more evenly. And it’s incredibly resilient: this is one of the most durable mattresses you can buy. If you’re looking for a comfortable, supportive, and sustainably produced mattress with no chemicals, you won’t find better.
Avocado Memorial Day sale: save $100 with code HONOR
From $899 – It’s rare we see a discount on the Avocado Green mattress these days, but there’s $100 off now for Memorial Day. That drops the price of a queen to $1,399 – just make sure you add the code: HONOR at checkout. View Deal
The Allswell is a hybrid bed-in-a-box mattress made from memory foam and coils. Backed by Walmart, it aims to deliver ‘luxury’ at a budget price – and while it doesn’t compare to mattresses that cost more, many reviewers say it does a good job for the money.
Inside, a generous layer of individually wrapped coils help reduce motion transfer, making it a good choice for couples. On top, cooling, breathable memory foam provides cushioning and extra support, while also preventing you from overheating. Allswell classifies the mattress as medium-firm.
Like the Nectar, The Allswell is a bed in a box. It’ll be shipped for free and arrive at your door rolled-up in a conveniently sized box, ready to sleep on within 24-48 hours. It also comes with a 100-night trial and 10-year warranty.
Bear in mind that some premium features have been sacrificed to achieve the budget price tag. It doesn’t have a removable cover, for example. There also isn’t a discount on this one in Allswell’s holiday sale. Nevertheless, The Allswell mattress offers good value for money. If you’re looking for a quality, budget option, it’s one of the best mattresses you can buy.
The Zinus Green Tea Memory Foam isn’t the best mattress you can buy – let’s clear that up straight away. As you’ll have seen in this guide, there are plenty of higher-end options with luxury materials and more advanced features. But if you’re on a tight budget, or looking to furnish a spare room without breaking the bank, this Amazon best-seller is very good indeed and well worth considering.
The Zinus Green Tea Memory Foam is an all-foam mattress. As the name suggests, it features green tea-infused memory foam, plus purified charcoal particles, which aim to neutralize odors and absorb moisture. It comes in a range of different thickness options: 6, 8, 10 and 12 inches, and the price increases with depth. We tested the 10-inch version – which starts from $217 – for three months and found it to be very comfortable and supportive, with good edge support and minimal motion transfer, so you won’t be disturbed by a restless partner. (In case you’re wondering, no, it doesn’t smell of tea…)
The fantastic price is, of course, where this mattress really stands out. It isn’t often you can buy a quality king size mattress for under $300. It’s also racked up a ridiculous amount of positive user reviews on Amazon – over 100,000 (May 2021), with an impressive average score of 4.4 out of 5.
There are a few questions about long-term durability: we don’t know how this mattress will perform after a few years of use. It’s not the best choice if you overheat at night, either – a few of our reviewers became uncomfortably warm. But all in all, we think the Zinus Green Tea Memory Foam mattress is popular for good reason. If you’re looking for affordable support and comfort, or want to give memory foam a try for the first time, it’s a top choice for the money.
How to choose the best mattress
There are two golden rules to follow when buying a new mattress. Firstly, make sure you choose the right size. A good rule of thumb for this is that your mattress should be 10cm longer than the tallest person sleeping in it.
Width-wise, if you’re sharing a bed, you and your partner should be able to put your hands under your head without your elbows touching. If you’re not sharing a bed, you want to be able to put your hands under your head without touching the edges of the mattress. Measure that distance, and as long as you choose a mattress that’s wider than that, you’re good.
Secondly, make sure it’s the right firmness. The best way to do this is by sleeping on the mattress for a few weeks – which is why all the best mattresses come with a risk-free trial period. Remember, though, that it can take up to three weeks for your body to adjust to a new mattress. That’s especially true if your old mattress wasn’t supporting you properly, so don’t assume that if you initially wake up sore it’s because the mattress is wrong – it may be your body getting used to better support. Most mattress trials specify a minimum of 21 days for exactly this reason.
If you are testing a mattress in a showroom, there’s a quick trick you can use to increase your chances of choosing an option that’s right for you. Lie down and place your hand in the small of your back: if there’s a big gap, it’s too firm; if there’s no gap, the mattress is too soft. Of course, this isn’t a fool-proof test – you do need to sleep on a mattress to be sure – but it’s a good way to narrow down options in a showroom.
Key considerations before buying a mattress
Bear in mind that what a mattress feels like to sleep on is subjective. How firm or soft you find a mattress depends on a wide range of factors, including your weight, height, body shape, sleeping style, and body temperature. That means that every mattress’s comfort level is relative, so each person (and mattress company) may gauge a firmness level differently. What feels supportive and pressure-relieving to you may feel too firm to someone else, even if you’re both side sleepers and about the same height and weight.
Keep this in mind when noting our “firmness gauge”, which ranges from 1 to 10, with 10 being the firmest. (Also, be aware that firmness ratings aren’t regulated and can vary across brands.) The only way to know whether a mattress is right for you is to sleep on it – which is why all our selections here come with a risk-free trial. If you don’t like one, you can send it back and try another.
Which is the best type of mattress?
There are a lot of different types of mattresses to choose between, and on first glance they can all seem a little overwhelming. But they needn’t be: mattress materials have advanced dramatically over the last five years, and the differences between each are increasingly negligible.
We’ve spent hours researching and reviewing the latest mattresses, and have pulled together a list of outstanding options here. We believe that you should be able to pick any of the options in our best mattress guide and be extremely happy with your choice, regardless of whether it’s made from copper-infused memory foam, coils, latex or a cutting-edge combination of all-natural materials.
However, it can be helpful to know what each mattress material is before you make your final choice – so here we’ve walked through the different options. As you’ll see, each has its pros and cons…
However, really, these days, all the materials have improved so much that there’s little to tell the difference between them in reality. Again, we advise making use of the trial periods to find the best mattress for your specific preferences.
- Memory foam is a good option for anyone who likes to feel ‘hugged’ by their mattress. It uses your body heat to mold to your shape, providing tailored support at pressure points and all-over cushioning. Traditionally it’s not been the best choice for anyone who tends to overheat at night, but memory foam has come a long way in recent years, and the best memory foam mattresses tend to come packed with special cooling materials.
- Spring mattresses have more bounce than memory foam, and can be cheaper. Traditionally they were a good choice for hot sleepers, due to the increased airflow throughout the mattress, but advancements in materials across the board means that’s not necessarily the case now.
- Hybrids can bring you the best of both worlds: the tailored support of foam, with the subtle bounce and increased airflow of springs. The coils in hybrid are usually smaller, though, and you’ll have less memory foam too.
- Latex mattresses use a super durable latex foam that’s made from natural materials, rather than synthetic materials (which memory foam mattresses are made from). The latex is less dense than memory foam and less prone to heating, and it’s a good choice if you want your mattress to really last, but it doesn’t come cheap.
Most of the options listed in our best mattress guide are available in twin, twin XL, full, queen, king and California king sizes – some come in split options too, which enable you to choose a different firmness to your partner.
Generally speaking, the bigger the mattress, the higher the price. Most of the twin mattresses are a few hundred dollars less and the king and California king mattresses average about $200 more than the queen size. Hybrid mattresses and Luxe or Premier versions generally cost more than the basic/original mattress prices listed.
