There are so many benefits to bed-in-a-box mattresses.

But that's why we're here to help you!

Sleep Hero is dedicated to helping you find the very best mattress for a good night's sleep. 😴

If you need some guidance to get started, we'd recommend you read these two articles:

Don't forget to check out our mattress reviews for a look at some of our favourite mattresses in the UK!

How should you start looking for a new mattress?

Do you need a new mattress?

If your old mattress is looking - and feeling - a little worn and you've been waking up with aches and pains, then it's probably time to upgrade your mattress. 👍

So how do you even begin choosing your brand new mattress?

Time to replace your mattress
Worn mattresses have to be replaced.

It isn't always easy, so here's a very quick guide to some of the factors you'll need to consider. 🤔

Decide on your budget

Some mattresses may be the best on the market but come at an enormous cost. 💰

And others are very expensive but are actually pretty shoddy.

value for money mattress
Always consider whether you're getting a value-for-money purchase.

While it is always worth investing in the best you can afford, a cheaper price tag doesn't necessarily mean it's an awful mattress.

In fact, some of our favourite mattresses offer phenomenal value for money.

To get started, why not take a look at our guides on the best luxury mattresses and the best cheap mattresses?

Consider your desired degree of firmness

Do you like soft mattresses, medium mattresses, or firm mattresses?

It's easy to think that soft mattresses offer zero support, but this isn't actually true.

Stability ensures your mattress can support you - and no matter your chosen firmness, a mattress should always offer good stability.

levels of firmness and comfort
Do you like your mattress softer or firmer?

The degree of firmness of a mattress merely refers to the feel or sensation you'll experience when lying down.

Personal preference plays a part in this, but so does your body weight, build, and preferred sleeping position. 🧸

We look at the way sleeping position influences your mattress choice a little further down.

Establish your ideal sleeping temperature

Do you easily feel hot at night? 🌡

Some mattress materials, like memory foam, retain more body heat than others.

We look at mattress materials in more detail further down.

If you need to figure out what mattresses are best if you're prone to overheating, then the simplest advice would be to go for anything with springs.

The spaces between springs create natural ventilation channels, allowing sprung mattresses to allow for much cooler sleep than their non-spring counterparts.

Determine your main sleeping position

Some mattresses are better suited to some sleeping positions than others. 🛌

While most people are combination sleepers, you may also be a pure front sleeper, back sleeper, or side sleeper.

three sleeping positions

Don't worry; we look at this in much more detail further down, or you can refer to the specific articles linked in the sentence above.

Confirm whether you're sleeping alone or with someone

Some mattresses are better suited to couples (and sex!) than others. 👩‍❤️‍👨

Your sleeping arrangement will also influence what size mattress to buy.

Of course, if you're sleeping alone, you can choose whichever mattress size you're most comfortable with (depending on your budget and the size of your bedroom).

But if you're sharing your bed with a partner, it's better to stick to larger mattress sizes.

How would you choose the best mattress material?

There are several different mattress materials to choose from, and there isn't necessarily a right or a wrong choice. 🙌

Mattresses can have any number of different fillings, ranging from synthetic foam to springs to natural coir and wool.

The material you choose depends on your personal preferences and sleeping requirements. 💤

Different mattress materials

The most popular mattress options include:

Mattress materials largely influence the specific characteristics of your bed.

We'll look at the most common mattress materials below. 👇

Best memory foam mattresses

Memory foam (also often called viscoelastic polyurethane foam or low-resilience polyurethane foam) is a foam made predominantly of polyurethane and a few additional chemicals to increase viscosity and density. 🧪

Memory foam is characterised by its so-called memory effect or memory imprint.

When you apply pressure to the foam, it leaves an imprint that will remain visible for a few seconds.

Like this:

tempur sensation mattress

tempur sensation mattress memory imprint

This memory effect allows the memory foam to adapt remarkably well to the body, resulting in body-hugging comfort, relief of pressure points, and orthopaedic support.

Memory foam responds to temperature, so it will be firmer when cold and softer when warmer.

As you warm up while sleeping, the foam will become softer and mould to your body even more. 🤗

Since memory foam is softer, most mattresses will include a top layer of memory foam with a cold foam base so you can still benefit from the right level of support.

Advantages and disadvantages of memory foam mattresses

One of our favourite memory foam mattresses is the Nectar.

It's not as soft as other memory foam options, making it an excellent mattress for a wide variety of sleepers.


On the downside, this temperature response also means that memory foam stores more heat than other types of foam.

If you're sensitive to temperature, sweat easily at night, or easily overheat, it's best to stay away from memory foam.

Even a thin layer of memory foam can drastically increase the temperature of your bed at night and affect your sleeping comfort.

Best pocket-sprung mattresses

There are many different types of spring mattresses. 🌀

These can be low-quality spring mattresses, like open coil mattresses, or high-quality spring mattresses, like pocket spring mattresses.

Pocket sprung mattresses
In pocket spring mattresses, each spring is housed in an individual pocket.

We would always recommend opting for higher-quality pocket-sprung mattresses.

In a pocket spring mattress, the spiral-shaped springs are all wrapped in individual fabric pockets - hence, pocket springs. 👛

Because they're not connected, as they would be in an open coil spring mattress, individual pocket springs can move independently of each other and ensure precise body adaption, allowing for better pressure relief.

Pocket spring mattresses won't ever just contain springs. 🙌

The springs will always be surrounded and covered by one or multiple layers of foam.

Some even have a cushioning pillow top for extra comfort.

Advantages and disadvantages of pocket sprung mattresses

One of our favourite hybrid pocket spring mattresses is the Simba Hybrid.

The mattress combines multiple layers of foam with mini pocket springs for superior body adaptation, and offers a sleep that's both comfortable and supportive.


Best latex mattresses

Latex mattresses can be made from natural latex, man-made synthetic latex, or a combination of the two. 😮

Natural latex is harvested from tropical rubber trees.

Since this doesn't damage the tree, it's considered a fantastic natural and eco-friendly alternative to man-made mattress materials. 🌱

Latex mattresses
Natural latex mattresses are eco-friendly, supportive and breathable - but often quite expensive.

Pure latex mattresses are costly and exceedingly rare to find, so most popular latex mattresses will also feature numerous other layers of foam. 💰

Many online brands only use a thin layer of latex in a layered mattress to enhance breathability and support.

But, you will be able to find a few pure latex mattresses.

Advantages and disadvantages of latex mattresses

The Dunlopillo Royal Sovereign, for example, is a fantastic latex mattress made of 100% natural latex.


How can you choose a mattress according to your sleeping position?

Your preferred sleeping position influences the type of mattress you should choose.

If you sleep on your side, for example, it's likely that you'll need a softer mattress, while stomach and back sleepers generally need a firmer mattress.

Let's look at the best mattresses according to sleeping position in more detail. 👇

Firmness according to sleeping posiiton

Best mattresses for side sleepers

We always recommend that side sleepers choose a softer mattress. ☁️

This is because side sleepers need a mattress that allows their hips and shoulders to sink in a little more deeply to achieve optimal spinal alignment.

Side sleepers should look for beds that:

  • Have high point elasticity (meaning that the mattress will give way where pressure/weight is applied but remain unaffected elsewhere).
  • Are a little softer.
  • Allow for ideal spinal alignment.
  • Come with integrated contour zones.

Suitable mattress materials include memory foam, cold foam, latex foam, and gel foam. ✅

Optimal spinal alignment for side sleepers
Side sleepers require a zoned mattress that allows for optimal spinal alignment.

Some pocket spring or hybrid mattresses, like the Simba Hybrid, may also be suitable but it's important to choose one that's not too firm.

Side sleepers on a firm mattress may experience higher levels of back, neck, and shoulder pain.

Foam mattresses, like the memory-foam-based Emma Original., are generally a good option since they allow for enough sinkage.


Best mattresses for back sleepers

Generally, back sleepers will benefit from slightly firmer mattresses. 🧱

This is because back sleepers require additional support, especially for the lighter parts of the body, like the head and feet.

If there isn't enough support at these points, your spine can't remain in an optimal alignment, which leads to lower back pain.

Back sleepers should look for mattresses that:

  • Have high-point elasticity.
  • Are a bit firmer.
  • Allow for even pressure distribution.

We would recommend mattresses composed of springs, firmer memory foam, gel foam, or cold foam. ✅

Back sleepers
Back sleepers generally do well on firmer mattresses.

We wouldn't recommend pure latex or memory foam mattresses as these may be a little too soft and won't offer enough stability. ☹️

The Panda Hybrid Bamboo mattress is an excellent choice, offering a slightly firmer feel.


Best mattresses for stomach sleepers

Sleeping on your stomach isn't the healthiest position and can result in quite serve neck tension. 😩

But we know that sometimes all you need is to hug your mattress.

Stomach sleepers should choose a firm mattress.

This is because firm mattresses provide sufficient support to the pelvis, which prevents the formation of a hollow back.

Stomach sleepers should look for mattresses that:

  • Are firm.
  • Allow for even pressure distribution.

These elements enable spinal alignment.

Mattress for front sleeper
We wouldn't recommend sleeping on your stomach - though it can be comfortable!

We would recommend mattresses with a spring core, as well as hybrid mattresses made of cold foam, gel foam, or memory foam.

One of the firmest mattresses we've tried is the Origin Hybrid, which would be well suited to stomach sleepers.


Please keep in mind, though, that if you sleep on your stomach, you're likely to struggle with neck and shoulder tension no matter the mattress you choose.

To alleviate some of this discomfort, avoid sleeping without a pillow and opt for an adjustable memory foam pillow, like the Brigthr Sleep Eclipse Pillow or the Nectar Whole Night's Sleep pillow, instead where you can sleep on only the thinnest layer for maximum comfort and some support.

You may also want to invest in a massage gun to loosen up some of that unavoidable tension.

How do you choose a mattress to meet specific requirements?

Not all mattresses are created equal - but neither are we.

You may find yourself in a position where you're looking for a particular type of mattress.

We have a whole host of these articles, which you'll find in the full listing at the bottom of this page, but here we address some more common concerns.

What mattresses are best for allergies?

If you're struggling with allergies, it's best to opt for pure foam mattresses.

woman with allergies on a mattress
There's nothing worse than being allergic to your bed!

Memory foam mattresses like the Nectar Memory Foam and the Emma Original are fantastic options.

Bed bugs and other allergy causers have much less space to survive in a foam mattress than they do in a mattress with springs.

It's also worth investing in synthetic sleep accessories, which are less likely to cause allergies, and allergy-friendly bedding materials like silk pillowcases.

What mattresses are best for back pain?

Back pain is a common concern.

Some pain may be caused by an unsuitable mattress, but you may also be struggling with regular issues due to poor posture, injuries, or illness.

people with back pain
Back pain is more than just annoying - it can seriously affect your life!

The best mattresses for back pain will offer orthopaedic relief and are likely to be made from softer, more mouldable materials like memory foam.

To find the best orthopaedic mattresses, take a look at our guide on the best mattresses for back pain.

What mattresses are best for sex?

Couples have unique requirements and most would be interested in finding the best mattress for sex.

While memory foam can be comfortable to sleep on, it may be the worst material for sex if it causes you to sink into the foam too much.

Something like a pocket spring mattress or a hybrid mattress, which offer good levels of support and some bounce, will be much better suited.

couple in bed
Couples may have slightly different mattress requirements.

Check out our full guide on the best mattresses for sex to find the most suitable option.

What's the best mattress for hot sleepers?

While the UK isn't known for its soaring temperatures, we have been experiencing some pretty warm days during the summer months.

Heat and sleep don't go well, and if you're sleeping on a mattress that retains more heat, you're likely to wake up in a sweat.

Head on over to our guide on the best cool mattresses so you can enjoy the optimal sleeping temperature year-round.

Which criteria should you look out for when buying a new mattress?

You can trust that we've done our research and will only recommend best-buy choices. ⭐️

But how do you know if a mattress is a good buy or not?

Woman confused

You can use these four simple criteria to guide you. 👇

1. Focus on quality mattresses

It may seem obvious, but the quality of your mattress really matters.

After all, your mattress directly affects the quality of your sleep - and your sleep affects the quality of your life!

Regardless of what mattress you go for, you should always opt for the highest quality you can afford. 👍

Determine the quality of foam mattresses

If you're considering the quality of a foam mattress, you need to look at the density of the foam used.

Density is measured in units showing how much foam was used for one cubic metre. 🧊

In general: The higher the density, the higher the quality of the mattress.

Higher-density materials are also likely to last much longer.

Density-quality indicator

This means you can enjoy your mattress for a longer time. 🗓

We'd recommend opting for a mattress of at least 40 kg/m³

Determining the quality of spring mattresses

To determine the quality of spring mattresses, you need to look at how many springs the bed contains. 🌀

The higher the spring count, the higher the quality of the mattress and the more likely it is to last.

We recommend choosing a mattress with at least 350 springs for the smallest size.

2. Find the right degree of firmness

Mattresses come in different degrees of firmness. ⛅️🧸🧱

As with mattress materials, there is no right or wrong choice here.

The right degree of firmness for you depends on your personal preferences and requirements. 🧐

different degrees of firmness

Your body type and preferred sleeping style also play a role:

  • Lighter-weight people and side sleepers often prefer softer mattresses.
  • Average-weight people and combination sleepers do well on medium-firm mattresses.
  • Heavier-weight people and pure back sleepers, and stomach sleepers often prefer firmer mattresses.

But as long as you're well-supported, any degree of firmness could theoretically work. 👍

What should a good mattress be able to do?

A suitable mattress relieves pressure and supports the body.

It’s designed to cushion the entire body while supporting the hips and spine. The shoulders, pelvis, and hips sink in so the body is balanced and the spine is aligned.

Mattress Expert

We've considered the best mattresses according to sleeping position in more detail above.

3. Choose the right mattress size

Choosing a mattress that will fit your bed frame and bedroom is essential.

Most mattresses are available in the standard UK mattress sizes. 🇬🇧

These include:

We'd recommend that couples go for a double bed or larger.

Standard UK mattress sizes

Some mattress brands offer European sizes, custom sizes, and the luxurious emperor bed size, but these are rarer. 👑

Of our favourite online mattress brands, only the Otty Hybrid is available in the emperor size.

45% OFF OTTY HYBRID£ 439.99

4. Pay attention to the trial period

Most mattresses purchased online come with a risk-free trial period. 🤩

A 100-night trial period is standard, but some mattress brands offer even longer trials.

  • Simba, for example, offers a 200-day trial period.
  • Nectar even offers a 365-day trial period.

Trial periods give you the chance to try out the mattress in the comfort of your own home - and allow your body to get used to the new bed. 🏡

Risk-free trial periods

Sometimes, it can take up to 3 weeks to get used to a new mattress, especially if it is vastly different from your old mattress!

We love a good risk-free trial period. 🥳

If you're not completely satisfied with your purchase, you can return the mattress for a full refund!

Do sleep accessories and bedding choices matter?

You may have the best mattress in the world, but you also want to make sure you can enjoy your entire sleep setup!

That's why we also explore the world of sleep accessories:

There is a whole world of decisions to make when choosing one of these, so we'd recommend heading straight to the linked articles for more information. 🤓
