Best mattress 2021 – 10 options for a (very) comfortable night’s sleep

If you’re looking for the best mattress then allow us to help. We know that finding the most perfect mattress to suit your sleep style and circumstances can be a very personal decision which is why we have personally reviewed every mattress featured in this buyer’s guide, aside from one which is work-in-progress.

We’ve considered all mattress types – memory foam, pocket-spring and hybrid mattresses (best of both worlds) – from a selection of price points to put together this list of the best mattresses for a range of sleepers. You’ll see some recognisable brand names such as Emma, eve and The Cotswold Company which have all been put through their paces to see if they deliver on their promises for a number of weeks, sometimes months. We’ve then based our reviews on how we found them in terms of comfort, support and quality, plus what they are like to unwrap as not all of them claim to be a mattress-in-a-box.

It sounds like a lot to consider but it’s so worth it, especially when you think that you’re going to be sleeping on it for a number of years. You’ll find our top choice below but it’s (also) worth knowing that a lot of the mattress brands now offer a trial so you can try-before-you-buy, so to speak, which means that you could have up to one entire year until you commit to anything more long-term.

Don’t forget to pick up the best mattress protector to shield your new mattress from allergy triggers and little accidents.

What is the best mattress to buy?

In short, the best mattress UK you can buy is the Brook + Wilde Ultima mattress. Our reviewer just couldn’t fault it, although it is mega heavy but how many times will you need to move it? There were big green ticks for every aspect; arrives in a box, NO lingering smell, temperature regulating and mega comfortable.

We do, however, also love the Emma Original Mattress which is available to our UK and US readers. It’s been a firm favourite for a couple of years with our readers and our reviewer very highly rates it, too. Again, we couldn’t fault it so it needs to be high up on your list of considerations.

If neither of those take your fancy then you’ll see that we have several more alternatives to explore. Our automatic price widgets will always show you the best prices which each mattress is available to buy for, too, so no more scouting around for the best deals either.

Who will the Brook + Wilde Ultima Mattress suit?
It’ll suit all sleepers since you can choose your preference of comfort feel (tensions): Soft, Medium, Firm, or Extra Firm

What is the Brook + Wilde Ultima Mattress like to sleep on?
It’s lovely. We tested it in the Medium comfort feel which was just right since we’re both side sleepers. It provided plenty of support no matter where you lay or sat on the bed as the tension remained the same. And our weight was evenly distributed (especially on our sides) which was a joy to relieve us from any aches or pains endured throughout the day.

There’s also no complaints in terms of temperature regulation as neither of us woke due to being too hot or cold

Special features?
The mattress is made to order which is amazing in its own right BUT if you and your partner have different comfort preferences, they can make a bespoke mattress which has different comfort feels.

Fillings?
There’s 10 layers to the Ultima Mattress which combines breathable memory foam, open-cell structure memory foam, a twin blanket of 2000 nano-springs and a twin layer of 4000 large pocket springs to create a breathable, supportive sleep zone.

What do you get for your money?
A 100-night comfort trial, 10-year guarantee and free delivery. The delivery guys will help you to carry it up the stairs (even in Covid times) and the after sales team will call you after a few days to see how you’re getting on with your new mattress.

Our (close) runner up for the best mattress is the Emma Original mattress. It’s been a hit with our readers across the Future Homes titles and it’s easy to see why…

Who will the Emma Original Mattress suit?
The Emma mattress is the best pick for those who tend to move lots in their sleep.

What is the Emma Original Mattress like to sleep on?
There pretty much nothing we don’t like about this mattress. It’s easy to switch positions, and comfortable in whichever position you favour for that matter. We’d rate it towards the firmer end of medium, but it’s certainly not rock solid. The mattress is evenly supportive across the entire surface, so there’s plenty of room to spread out. 

Special features?
The breathable, removable top cover can be washed at 60 degrees, which is going to bust dirt better than the standard 40 degrees. Handles make it easier to manoeuvre.

Fillings?
Three layers of foam. The top layer is an elastic foam called Airgocell, which brings you pressure relief. The memory foam layer is next and, like all memory foam, keeps you comfortable in any position. The base is made from Cold Foam that supports the above layers, as well as you. 

What do you get for your money?
A 100-night sleep trial, no questions asked, 10-year warranty and free delivery, usually within one to three working days.

3. Simba Hybrid Pro Mattress

Best hybrid mattress made from recyclable, natural materials (UK)

Specifications

Size: Single – super king

Depth: 28cm

Type: springs, foam, memory foam and wool

Comfort grade: Medium

Reasons to buy

+Good (lack of) motion transfer+Very cool nights sleep+10 year guarantee+Arrives in a box+Made in UK

Reasons to avoid

Heavy (in the box)Smell lingers for a few days

The Simba Hybrid Pro is (another) premium mattress which is reflected in the price. Yes, it’s towards the higher end but I loved reviewing it so it is one which I can highly recommend.

Who will the Simba Hybrid Pro mattress suit?
It’s a medium tension so it’ll suit side or front sleepers well since they can sink in (a little) for unrivalled comfort.

What’s the Simba Hybrid Pro mattress like to sleep on?
Dreamy. After the first week or so I was fully adjusted to sleeping on this one. There was also very little motion transfer and a good balance between sinking into the mattress so your shoulders aren’t too squished (when sleeping on the side), to equally being very well supported.

Special features?
One of the layers in the mattress is a wool layer which sets this mattress apart from the others in this guide. Not only is it a hybrid mattress with springs and foam but it is also naturally temperature regulating which is good news for hot sleepers. 

I’m not a hot sleeper by any standards – and we tested this mattress during the winter months – but at no point did I wake up during the night overheating which can tend to happen when the central heating is on.

Fillings?
There’s seven incredible layers built-in to this mattress which all work together to give you a comfy nights sleep. A point of difference with this mattress when compared to the Simba hybrid mattress is that it has a hypoallergenic cover which is super-soft, comfy and breathable but is not removable, despite there being a zip underneath the base. It also has a natural wool layer which is naturally temperature regulating and two wonderful layers of up to 5,000 25mm, individual conical pocket titanium alloy Aerocoil™ springs for better body weight distribution.

To make up the total number of layers here is also an open-cell foam layer, high definition foam with edge support and a zoned support base.

What do you get for your money?
Every Simba mattress comes with a ten year guarantee, free delivery to most addresses in the UK and free returns if you decide the mattress isn’t quite right for you during the 200 night trial.

4. Avocado Green Mattress

Best natural mattress which uses organic, natural materials (US)

Specifications

Size: Twin – Cal king

Depth: 11 inches

Type: Hybrid

Firmness: Medium to Firm

Reasons to buy

+Sustainably harvested latex rubber foam+Best for back and side sleepers+No fire retardants+Arrives in a box+Handmade in Los Angeles

Reasons to avoid

On the firm side

An eco-friendly option to retire to at the end of each day is the Avocado Green Mattress. Like the Dursley (above), it’s also handmade but in Los Angeles not Devon in the UK and is uncompromising when it comes to quality. If it’s in your budget, it’s worth every penny…

Who will the Avocado Green Mattress suit? 
Our reviewer for this one (state-side) felt that this mattress is well suited to side- and back-sleepers, and those with chemical sensitivities or allergies. Plus, anyone committed to living a greener lifestyle

What is the Avocado Green Mattress like to sleep on? 
It sits on the firmer side of medium, and the Avocado rates it a seven out of 10 (with 10 being the firmest). It’s designed with a soft top layer that’s constructed from latex foam to add comfort to its already supportive base — that’s made of up to 1,414 individually tuned, tempered steel coils (with the exact number depending on the size of mattress you ordered). Plus, this mattress is divided into five ergonomic “zones” designed to keep comfort at a premium and motion transfer at bay.

Oh, and for those who prefer a softer feel, the mattress is also available with a plush cotton pillow top. 

Special features?
Instead of chemical flame retardants, the Avocado Green Mattress meets U.S. flammability standards with an all-natural fire retardant: wool. It’s also one of only three mattress brands in the world to be MADE SAFE Non-Toxic certified.

Fillings?
The base of this two-layer hybrid mattress is built from fabric-wrapped innerspring coils. Whereas, the top layer is made of latex foam and foam covered in a GOTS-certified organic cotton casing. 

What do you get for your money?
The brand offers a 100-night trial period. And after that? There’s a 25-year guarantee — which is one of the longest warranty’s we’ve ever reviewed.

5. The Cotswold Company Dursley Mattress (Firm)

Best natural mattress which has been handcrafted in Devon from the finest materials (UK)

Specifications

Size: Double–super-king

Depth: 27cm

Type: Pocket-sprung

Comfort grade: Firm

Reasons to buy

+Tension is true to word+No motion transfer+Beautifully handcrafted+Made in the UK+8 year guarantee

Reasons to avoid

Doesn’t arrive in a boxSmells after unwrappingNot available as a singleNo trial period

If you specifically want a handcrafted, natural mattress then the Cotswold Company Dursley could be the best option for you. It is a firm mattress which made for a good comparison against it’s memory foam rivals during testing and I, for one, am rather fond of it.

Who will the Cotswold Company Dursley mattress suit?
Because of the firm tension, this mattress would be well suited to back sleepers as well as fidgets and sustainability advocates.

What’s the Cotswold Company Dursley mattress like to sleep on?
Admititably, I’m a side sleeper and found the mattress to be true to tension. A couple of pillows to prop up the head and a cotton quilted mattress protector really helped to soften the feel of the mattress. I would even say that a mattress topper could give some extra cushioning. Yet when rolling onto my back during the night, any aches and pains were soon stretched out and it felt like lying on a cloud thanks to the pillow-top surface.

The tension is consistent across the mattress which meant that you could barely feel any movement from a restless partner. And being made from entirely natural materials – which is hard to come by – would mean that in any month of the year the mattress, and your body, will be able to breath and be naturally kept cool.

Special features?
Each mattress is unique because it has been handcrafted. It boasts some beautiful detailing such as the hand stitching which you can see everywhere across the mattress; the edges for support, the handles for easy turning and the hand tied pure wool tufts (my personal favourite).

Fillings?
There are five layers to The Dursley which includes a wonderful combination of British wool from Dartmoor, 100 per cent pure Egyptian cotton and 1200 Comfort Intelligence pocket springs.

What do you get for your money?
An eight year guarantee plus the option of free delivery.

There is no trial period with these mattresses, however, so if you aren’t happy with your new mattress you are unable to return it due to hygiene reasons.

Rem-Fit hybrid 400 mattressLivingetc badge – tried, loved

6. Rem-Fit 400 Hybrid Mattress

Best mattress with edge-to-edge support for taking a combined weight of up to 40 stone (UK)

Specifications

Size: Small single – super King

Depth: 25cm

Type: Memory foam + pocket spring

Comfort grade: Medium-firm

Reasons to buy

+Mega supportive+Great motion transfer+Advanced temperature regulation+Designed and made in the UK

Reasons to avoid

Slight lingering plastic smell, but it does go within a few days

The Rem-Fit 400 is a hybrid mattress which is both comfortable and supportive.

Who will the Rem-Fit 400 mattress suit? 
This mattress would be a treat for all sleepers, whether you’re a fan of memory foam or not. It will comfortably withstand a combined weigh of 40 stone, too, so if you’re closer to 20 stone your sleep position will be fully supported – even if you find yourself perched on the edge of the bed during the night.

What is the Rem-Fit 400 mattress like to sleep on?
Really lovely, after the first few nights. According to the Ts & Cs at Rem-Fit they recommend that you sleep on your new mattress for a minimum of 30 nights to allow enough time for your body to fully adjust, which gives some comforting encourage to pursue (it’s worth it, honest).

Our reviewer tested it throughout the summer months when there were some temperature highs and lows. The mattress didn’t cause any over heating. And even if there was some restlessness, you wouldn’t know it because the motion transfer is great – you wouldn’t even know your companion is there (unless they steal the bed sheets from you).

Special features?
The first layer of the mattress (out of five) is the Re-AX breathable cover which encases the 25cm-deep Hybrid. It’s removable and machine washable, too, which will make caring for the mattress nice and easy.

Fillings?
For a hybrid, there’s nothing too out of the ordinary with this mattress. But it does use a combination of cool open-cell memory foam and 2000 premium pocket springs, plus foam encapsulated the side walls with edge-to-edge support for a very supportive base to lie on at the end of each day.

What do you get for your money?
A 100 night sleep trial with no quibbles if you’re not completely satisfied; 15 year full replacement guarantee at no extra cost and free next day delivery (when you order before 1pm).

Type: Comfort foam/memory foam

Firmness: Medium

Reasons to buy

+Cool, comfy foam+Medium firmness+Good for all sleep positions+Good for motion transfer+Comes in a box

Reasons to avoid

Usual chemical smell when you unpack it, but it will fade

This award-winning dual foam mattress scores big on comfort and coolness and is bound to be beloved by any side sleeper who suffers from joint pain.  

Who will the Casper Original Mattress suit?
It’s a good choice for anyone seeking memory foam with a bit of bounce. It you, or your partner, are a fidget and / or you tend to over heat, this is a good option for you too.

What is the Casper Original Mattress like to sleep on? 
Our reviewer found that it is one of the softer options of memory foam mattresses on the market which means that you’ll notice that your hips and shoulders sink lower than the rest of your torso, to ensure an ergonomically aligned spine. But don’t be alarmed! There is little motion transfer, so your partner will never notice any tossing or turning on your end in the wee hours of the night. 

And best of all? The cooling layer! It’s breathable, which again aids in that undisturbed sleep we previously discussed. 

Special features?
There’s nothing partcularly special about this mattress, aside from the impressive-sounding of the foamy layers, zone support and breathability (etc).

Fillings?
This model features a four-layer mattress that is tucked neatly away within a softcover. The top layer is an open-cell foam that provides immediate bounce and cooling properties. Next, there is a high-density memory foam layer that is there to support your pressure points. The Transition Layer deals with even weight distribution, and the final layer acts as a supportive base that helps keep everything stable. Together, all four layers are there to provide sleepers with their best night’s sleep ever. 

What do you get for your money?
When purchasing this mattress, you’ll receive a 10-year limited warranty, free delivery, and returns, plus very good customer service.

Who will the Nectar Memory Foam Mattress suit? 
It will reign supreme for those who are looking for a completely risk-free experience that includes a decent memory foam mattress and is available at a fair price. 

What’s the Nectar Memory Foam Mattress like to sleep on? 
Thanks to its memory foam filling, the Nectar Mattress will make your joints feel cushioned from night one. With regards to motion transfer, the Nectar is as good as any memory foam — and if sliding into your other half during the night is a massive bug-bear? Then, this mattress is the best find for you.

Fillings?

Finally, the seven-zone base foam provides additional contoured support plus depth. 

What do you get for your money?
An unprecedented 365-night trial period. Plus free delivery and free returns.

Next up on our best mattress list to claim third position is the eve Premium Hybrid mattress which, like the Emma, provides impressive support and is of a very decent thickness indeed. It’s just much pricier, especially at full price…

Who will the eve Premium Hybrid mattress suit?
It’s a good choice for those who like/need firm support – particularly if you have a bad back or achy hips.

What’s the eve Premium Hybrid mattress like to sleep on?
This is one of the deepest mattresses in our guide, which was the very first thing we noticed about it and is good for hoisting yourself out of bed every morning. It’s FIRM so this may take a bit of adjusting if  your last mattress was any softer.

Best hybrid mattress with an organic cotton cover (US)

Specifications

Sizes: Twin, twin XL, full, queen, king, Cal king

Depth: 29cm

Type: Hybrid

Firmness: Medium

Reasons to buy

+Comes in three firmness levels+Hybrid combines memory foam and coils+Organic cotton cover, CertiPUR-US foam+Stays cooler than an all-foam mattress+180-night home trial

Reasons to avoid

None that we can think of!

We like the Saatva mattress for a whole bunch of reasons, but to put it simply: this one’s got a lot of things going for it. 

Who will the Saatva Classic Mattress suit?
Anyone – especially those who are in some discomfort from back and joint pain. In fact, this mattress has been recommended by leading U.S. chiropractors and awarded a seal of approval by the Congress of Chiropractic State Associations so it’s well suited to those who need a confidence boost to what their buying, too.

What is the Saatva Classic Mattress like to sleep on? 
Our best comparison is to a high-end hotel bed. The pillow-top has got a cozy, sink-in factor. And then the innerspring layer below adds plenty of support for spinal alignment and pressure point elimination. 

The mattress comes in three firmness levels; Plush Soft, Luxury Firm, and Firm, with  the medium-rated Luxury Firm version being the most popular amongst customers. 

Special features?
One reason why we love a hybrid mattress is that it is better than standard memory foam with its edge support and airflow. The Saatva mattress looks to offer excellent perimeter edge support thanks to dual-reinforced edges, which means no more sinking into the mattress as you perch on the edge to put shoes on. And the coil construction allows airflow that’s hard to match from an all-foam mattress.

Fillings?
The top of the mattress is a pillowtop made from CertiPUR-US foam, enveloped in an organic cotton cover. Down into the middle of the mattress features the brand’s Spinal Zone active wire support system, designed to maintain spinal alignment. The coils are made from recycled steel. 

What do you get for your money?
This one comes with free delivery and in-home setup, plus optional free removal of your old mattress. Plus, you’ll get a 120-night in-home sleep trial.

Currently in review

How often should I change my mattress?

According to the National Bed Federation (and The Sleep Charity), it is recommended that you replace your mattress every seven to eight years. It’s likely that your mattress has become worn out long before you even realise it which is why this time frame is so important to bare in mind. 

Remember, a mattress protector – or a mattress topper – would be a good idea to keep your mattress feeling (and looking) like new so at the point of buying a new mattress, slip one of these on.

How to choose a mattress?

Ultimately it depends on the level of support you need, the space you have and your budget. The type of mattress – foam, pocket-sprung or hybrid – and materials used can also come into play at the point of choosing a mattress, based on your experience.

If you already have a bed frame then you’ll just need to get the same size mattress to fit it. This will work in the same way if you want to upgrade from a double to a king. A number of high street stores and brands sell mattresses and bedframes so to make life a little easier, it might be best to buy these at the same time. This was you can ensure that you can the correct bed frame and bed base to support the mattress adequately.

Have a little think about how you sleep, too. Are you a side, back or front sleeper? Do you struggle to regulate your temperature during the night? This can all affect the type of mattress you opt for. If you’re unsure, then do take advantage of the trials which brands are offering. These range from 100 to 365 nights which is plenty enough time to find the best mattress for you (and your partner) for free.
