NEW: See the top 7 SOFT mattresses for side sleepers here.

Do you sleep on your side?

Then you’ll probably know there are a few problems with this sleeping position that are a bit more serious than simply waking up with drool on your pillow.

The main one that I’ve experienced is shoulder pain – and even hip pain – due to the increased amount of pressure that sleeping on your side puts on these areas of your body.

And if you choose the wrong level of support or firmness, then your brand new mattress could actually become a rather expensive torture device – ruining your sleep and causing ongoing health problems such as insomnia.

That’s why below, I’ve listed the top 5 best mattresses for side sleepers that you can buy online in 2020 to make your shopping experience that bit easier.

I’ve also included a thorough buying guide at the end of this article that explains exactly what you need to consider when looking for a mattress if you sleep mostly on your side.

I hope you find it useful 🙂

And if you click the red ‘check price now’ button under each review you can buy that mattress now.

1: Best Memory Foam Mattress – Sweetnight

I’ve picked out this 10 inch gel memory foam mattress from Sweetnight as the best mattress for side sleepers with back, shoulder, neck, or hip pain – who also tend to sleep hot and require good motion isolation to stop them getting woken up by their partner or pets.

Designed for Back Pain Relief

This mattress is designed for the relief of back pain thanks to it being medium-firm and having a 4 layered foam design.

More specifically, you get a 2 inch gel infused memory foam top layer that provides pressure relief on your hips and shoulders – two areas that are hot spots for pain for side sleepers.

This top layer combines with a 1 inch ventilated comfort foam layer and a 4 inch air-flow, open cell sub-layer to help you sleep cool all night.

And lastly, there’s a 3 inch, high density support layer that sits at the base of the mattress to keep your spine in its natural alignment to protect you from back ache as you sleep on your side.

But that’s not all.

Flippable for Varying Comfort

This mattress is double-sided and can be flipped over so that you can experiment with differing degrees of firmness to help you find the ideal pressure relief.

Which is rare for memory foam mattresses because they typically have a unilateral one sided design that prevents flipping.

This ability to flip (and rotate) your mattress could even extend its life because you can distribute the cumulative load that it’s exposed to over time more evenly.

Other Benefits

  • Good motion isolation to prevent you and your partner waking each other up as you move during the night.
  • Made from CertiPUR-US® foam to limit emissions and avoid harmful substances such as formaldehyde mercury, lead, and other heavy metals.
  • Better edge support thanks to the high density support foam so you won’t feel like you’re falling off.
  • Breathable mattress cover that can help to prevent odours and mold growth.
  • Comes in a compressed box – making it easier to carry to your room.
  • Fits many different frame types – including box spring, adjustable, and slatted base.


  • Heavier-weight side sleepers over 200 lbs may sink too far into this mattress because it’s only 10 inches thick.

Recommended For

  • Average weight side sleepers (130 – 200 lbs) because of the pressure relief, support, and mattress thickness.
  • Lighter weight side sleepers under 130 lbs MIGHT find the softer side of this mattress comfortable.
  • Chronic back, shoulder, neck, and hip pain sufferers due to the pressure relieving top layer and denser support layers.
  • Hot sleepers because the gel and open cell comfort layers will help you stay cool at night.
  • Couples of similar weights and sleeping positions because the motion isolation will minimise disturbance as you move around in your sleep.
  • Although not explicitly listed as a hypoallergenic mattress, allergy sufferers might like this mattress because memory foam tends to repel allergens like dust mites.

Final Word

This is my top rated mattress for side sleepers overall because it is very well priced for the level of quality that it offers.

Furthermore, this mattress is suitable for a wide range of side sleepers with specific needs such as being able to sleep with back pain, arthritis, join paint, and a tendency to sleep hot.

2: Best Hybrid Mattress – Sweetnight

Whilst memory foam mattresses are typically a very good choice for side sleepers – hybrid mattresses are arguably better.

Especially if you’re a heavier side sleeper over 200 lbs.


Because the top layer can provide custom pressure relief via memory foam whilst the spring support core can provide outstanding spinal support that may surpass that achievable with memory foam.

Best for Heavier-Weight Side Sleepers Over 200 lbs

And that’s why I’ve picked this ‘mattress-in-a-box’ from Sweetnight as the best hybrid mattress for heavier side sleepers.

Because it’s constructed with 775 individually wrapped coils to provide a custom level of support for your spine and distribute your weight evenly to prevent back ache.

And this mattress is 12 inches thick; making it better if you’re on the heavier side because it’s got 2 inches on the pure memory foam mattress from Sweetnight – meaning that you’re less likely to sink through and touch the support layers beneath.

Whilst the plush, pillow top outer layer maximises pressure relief on your shoulders and hips to increase comfort.

This means that this mattress is still probably a good option even if you weigh less than 200 lbs because the extra softness will allow lighter-weight sleepers to sink into the mattress for comfort.

Other Benefits

  • Leverages gel and open cell memory foam to keep you cool and comfortable.
  • Uses CertiPUR-US® certified foam to minimise emissions and eliminate harmful substances like heavy metals and formaldehyde.
  • Comes in a compressed box that’s easy to move to your bedroom.
  • Fits most base types including adjustable, box spring, and slatted bases.


  • Expect some mild off gassing – the ‘new’ smell should go away in a few days.

Recommended For

  • Heavier-weight side sleepers due to the extra thickness and strong support core.
  • Sleepers who alternate between back and side due to the good support.
  • Average and lighter-weight side sleepers because the plush pillow top will provide enough ‘give’ to reduce the pressure on your hips and shoulders.
  • Couples with similar sleeping styles and body weights because the motion isolation will stop you from waking each other up.
  • Side sleepers who hug the edge of the bed because the core support layer increases edge support so you won’t feel like you’re falling off.

Final Word

If you’re too heavy for the pure memory foam mattress from Sweetnight then I recommend that you take a look at this memory foam and innerspring hybrid alternative.

Because it can provide the extra support that you need to take your weight whilst still providing the right amount of pressure relief on your hips and shoulders to keep you comfortable as you sleep on your side.

This is also a good mattress if, like me, you tend to alternate between sleeping on your side and your back because the support is still good enough to keep your hips in the correct alignment when you’re on your back.

3: Best Luxury Mattress – BedStory

If you’re looking for a more luxurious mattress for side sleeping then I recommend that you check out this 12 inch, gel infused, Euro top, hybrid mattress from BedStory.

Because the medium firmness and soft top layer make it ideal for average and lighter weight side sleepers.

More specifically, the 1 inch cool gel memory foam top layer contours to your exact body shape to relieve pressure on key areas like your hips and shoulders – enhanced by the 2.5 inch wave foam sub layer.

Beneath this sits a 1 inch support foam layer on top of a 7.5 inch pocket coil core to provide custom support to keep your spine in its ideal alignment.

Other Benefits

  • Sleeps cool thanks to the gel infused beads and open cell foam.
  • Excellent motion isolation thanks to the 744 individually wrapped anti-deformation and anti-rust springs.
  • High-hardness springs in the outer 2 rows to guard against sag.
  • Foam is designed with a fire resistant barrier for added safety.
  • CertiPUR-US® certified foam to minimise emissions and eliminate harmful substances like heavy metals.
  • Made from eco friendly materials.


  • Mattress should be ready for immediate use but may take up to 72 hours to fully expand once unpacked.

Recommended For

  • Heavier weight side sleepers due to the mattress thickness and support core.
  • Average weight side sleepers due to the medium firmness.
  • Lighter weight side sleepers because the soft top will allow you to sink into the mattress to provide pressure relief.
  • Couples because the individually wrapped coils will help to reduce motion transfer.

Final Word

I think that this is an excellent mattress that could potentially suit a wide range of sleepers from light to heavier weight – due to the combination of the support core and the memory foam top layer.

This is also one of the best value mattresses for side sleepers that I’ve seen based on the qualities it’s offering.

4: Best Innerspring Mattress – Modway

Generally speaking, the old-style Bonnell innerspring mattresses aren’t typically the best option for side sleepers because the coils tend to increase pressure on the hips and shoulders.

But in today’s mattress climate, things have improved greatly.

For example, Modway advertise their Jenna mattress as being an innerspring – but in my opinion, it’s more of a hybrid.

Because the outer layer is made from 1 inch of responsive foam that sits on top of 3 inches of egg crate foam to relieve pressure on your hips, shoulders, and back.

And if you opt for the 14 inch mattress thickness, you’ll also get 10 inches of individually wrapped coils to help give you the best possible support and motion isolation.

This means that you’re getting a great balance of support and pressure relief that could be suitable for side sleepers of varying weights.

Other Benefits

  • Easy to set up – comes in a compressed box.
  • Incorporates a fire resistant polyester barrier.


  • The ‘new’ smell may last a few days but should go away completely.

Recommended For

  • The 14 inch option is better for heavier weight side sleepers because the extra thickness will give you more support.
  • Average and lighter weight sleepers because the plush pillow top allows for enough ‘give’ to take the pressure off your hips and shoulders.

Final Word

This is the best innerspring mattress for side sleepers that I’ve seen advertised because the pillow top outer layer removes the age-old problem of the springs creating too much pressure on your hips and shoulders.

5: Best Latex Mattress – BedStory

I think that the best latex mattress for side sleepers is this 10 inch latex infused memory foam and pocket spring mattress from BedStory.

Because fundamentally, the top layer combines with the independently wrapped coils to provide the pressure relief and support that you need as a side sleeper.

But the inclusion of the 100% natural latex in the top layer has some additional benefits too.

The main one being that latex is more breathable than memory foam so this is a good mattress for you if you tend to sleep too hot in pure memory foam mattresses.

Also, latex is more ‘bouncy’ than memory foam, meaning that this mattress will allow you to move around during the night without getting ‘stuck’ in the materials – critical if you’re a ‘combo’ sleeper that switches positions often.

If you suffer from pollen or dust mite allergies, then the hypoallergenic properties of this latex mattress will benefit you because allergens typically have a harder time penetrating the outer layer.

It’s also designed to fit a wide range or frames, such as: box spring, traditional, platform, and adjustable bases.

To set this mattress up, place it on your bed frame and carefully cut away the plastic to allow the mattress to expand.

It’s probably best to use scissors instead of a knife so that you don’t risk cutting the mattress material.

Other Benefits

  • 5 inch foam layer for added edge support.
  • Uses CertiPUR-US® certified foam to minimise emissions from VOCs (volatile organic compounds) and avoid harmful substances like formaldehyde, mercury, lead, and other heavy metals.
  • Individually wrapped coil springs to limit motion isolation and stop you and your partner waking each other up during the night.
  • Vacuum sealed in a compressed box for easy delivery and mobility.


  • The 10 inch option may be too thin for heavier weight sleepers.
  • Make take up to 72 hours for the mattress to fully expand.

Recommended For

  • Side sleepers in the 130 lbs to 200 lbs weight range due to the balance between comfort, support, and the thickness of the comfort and support layers.
  • Side sleepers with allergies due to the hypoallergenic properties of the latex.
  • Hot sleepers because latex is naturally more cooling than pure memory foam.

Final Word

I personally think that this is the best natural latex mattress for average weight side sleepers with allergies because it provides the right balance between support and pressure relief – whilst also leveraging the hypoallergenic nature of latex to limit allergic reactions and hinder mold growth.

This mattress is also going to be good for you if you’re a side sleeper that wriggles around a lot during the night because the inclusion of latex makes the top layer more buoyant and thus easier to move around in.

Also, if you’re the type of side sleeper that tends to hug the edge of the bed then the 5 inch foam edge support will stop you from feeling like you’re going to fall out.

Side Sleeping Considerations

When it comes to the different sleeping positions, you have: back, front, and side – with ‘combo’ sleepers cycling through the various positions during the night.

As a child, I used to prefer sleeping on my front. But since my joints now ache considerably more, I find myself sleeping more on my side and back.

Here are some things to keep in mind if you prefer to sleep on your side.

Side Sleeping Positions

There are actually several variations on the side sleeping position which are as follows:

  • Foetal – with your knees curled up to your chest.
  • Log – with your legs and arms more outstretched.
  • Yearner – with your arms more perpendicular to your body.
  • Edge hugger – lying close to the edge of the bed with one arm over the side.

Side Sleeping Benefits

Some of the anecdotal reports that I’ve read say that side sleeping could potentially help reduce heartburn, prevent snoring, improve digestion, clear your lymph, and improve brain health.

But I wanted some more scientific substantiation, and according to WebMD, some of the apparent benefits of sleeping on your side include [1]:

  • Allows your spine to rest in its natural alignment.
  • Improves circulation to the baby for pregnant women.
  • Can improve sleep apnea symptoms such as snoring.
  • Reduce neck and back pain thanks to keeping your spine neutral.
  • The fetal position may help guard against Alzheimer’s or Parkinson’s because you brain can clear waste more effectively.

Side Sleeping Cons

The main problem with sleeping on your side is that you could potentially increase the pressure on your shoulders, hips, and back if your mattress is too firm or lacks the right amount of support.

Also the straighter your legs are, the greater the risk of pelvic rotation which could increase the amount of pressure placed on your spine and the surrounding muscles – potentially causing you to wake up feeling like you’ve ‘tweaked’ your back.

Referencing WebMD again, some of the other potential drawbacks to sleeping on your side may include [2]:

  • Lung and diaphragm compression – extend your legs slightly to fix.
  • May increase pressure on the hips – alleviate with a pillow between your knees.

What is the Best Mattress for Side Sleepers?

The best mattress if you’re a side sleeper is one that provides enough support to keep your spine in its natural alignment – whilst also conferring the right amount of firmness to relieve the pressure on your hips and shoulders.

This means that when you lie on the bed, you should feel as though your entire body is being supported equally – without a gap under your side, or the mattress digging into you either.

At the same time, you shouldn’t feel like you’re being swallowed up by the mattress – which would indicate that the bed isn’t providing you with enough support via the lower layers.

But don’t just take my word for it – because this scientific study concluded that the ‘stiffness’ (firmness) of the surface being slept on ‘…can have a significant effect on keeping the spine healthy’ [3].

Hopefully, the above list will have helped you narrow down your selection.

But if you’re still not exactly sure how to find out what the best mattress is for you, then simply apply the following steps during the research process.

1: Choose the Correct Firmness

As a side sleeper – selecting the right mattress firmness is critical.

And I can personally attest to this having recently spent a rather uncomfortable night on a hotel mattress that was too firm for my side sleeping preferences – causing me to awaken to a dull ache in my left shoulder that lasted all morning and well into the afternoon.

Also, if a mattress is too firm for you, you might experience your hands, arms, legs, or feet going numb – which is really not great for your circulation.

Hence why I’ve already written a comprehensive, step-by-step guide that explains how to choose the correct mattress firmness based on your body weight, the mattress materials, and other significant factors.

But as a general rule, you’ll need a mattress with a softer top if you sleep on your side because it will reduce the pressure on your shoulders and hips.

Here’s a few more points to consider.


Image source: stock image used with permission.

Body Weight

More specifically, when choosing your mattress, you’ll want to start with a ‘medium’ firmness and then make adjustments based on your weight.

For example, if you’re under 130 lbs then you might want to consider a medium-soft – or even a plush/soft – firmness because the reduced surface tension will allow you to sink into the mattress a little bit more.

This is important if you’re a lightweight side sleeper because your relatively lower mass means that you’ll typically sit more ‘on top’ of a medium mattress – which can increase pressure on your hips and shoulders.

But the opposite is typically true if you’re a heavier-weight sleeper over 200 lbs.

You’ll probably need a medium-firm – or even a firm – mattress to provide more surface tension to ensure that you don’t sink too far into the support layers.

However, you’ll still need a bit of ‘give’ in the top ‘comfort’ layer to ensure that your shoulders and hips can sink into the material to prevent discomfort.

How to Gauge Mattress Firmness

Many mattress manufacturers use a scale of 1 to 10 to help you gauge the firmness – with 1 being the least firm and 10 being the most firm.

I’ve looked at many different firmness scales and there’s often some discrepancies between brands and even mattress review sites – but a mattress with a rating of around 3 (plush/soft) to 7 (firm) should be suitable depending on your body weight.

Another fancy metric that you might hear when a sales person is trying to sell you a bed is ‘indentation load deflection’ (ILD).

Now, as I said in my ILD guide, I personally think that there are too many variables at play to exclusively use ILD values as a reliable indicator of mattress firmness and ultimately comfort, but the general rule is that as ILD increases – so does the firmness.

And I’m all about making things as simple as possible.

So here’s a table that you can use as a guideline to help you find the right mattress firmness if you’re a side sleeper based on your body weight.

Side Sleeper WeightApproximate Suitable Firmness
<130 lbsMedium-soft or soft/plush
130 – 200 lbsMedium
200 – 230 lbsMedium-firm
>230 lbsFirm

2: Select the Appropriate Support

Mattress support and firmness are NOT the same thing.

Firmness relates to the amount of pressure relief that you experience when lying on the bed – whilst the support relates to the degree by which the lower layers are able to support your body weight and keep your spine in the correct alignment.

As such, you could have a ‘soft’ mattress that’s still able to provide good support thanks to high quality lower support layers.

Firmness and support combine to provide the overall comfort of your mattress.

Finding a mattress with the correct level of support when you sleep on your side is important because with a mattress that is lacking in this quality – you could end up with back, hip, and even neck pain if your spine isn’t kept in the correct alignment as you sleep.

Now, all mattress companies will say that their mattress offers ‘great support’ but actually finding out if the mattress in question has the right amount of support for YOU as a side sleeper can be tricky.

Here’s a few guidelines to help you out.


As I just said, the top layers of the mattress are responsible for the firmness, whilst the lower layers are responsible for the support.

As a general rule, you’ll typically find that mattresses with individually wrapped, pocket coils and a high coil count are pretty good at providing support.

If you’re looking at a foam mattress, then you’ll want to ensure that the lower support layers are made from high density foam so that you don’t sink too far into the mattress.


The heavier you are, the thicker you’ll want your mattress to be as a general rule.

Otherwise, as a heavier sleeper, you may find yourself sinking through the comfort top layers and end up touching the support layers below.

I see a lot of heavier sleepers saying that mattresses that are 12 or even 14 inches thick are more suitable than the 10 and 8 inch alternatives.

More specifically, a comfort (top) layer that’s at least 4-5 inches thick can help stop you from ‘bottoming out’ and touching the support layers below – a phenomenon that could actually make your mattress feel firmer than it really is.

Body Weight

This factor encompasses the two points above.

If you weigh more than 200 lbs, you’ll probably be better off with a thicker mattress that has a high quality innerspring, or high density foam support layer.

Because as a heavier side sleeper, it can be surprisingly easy to have your hips sink too far into the mattress and give you back pain.

3: Consider the Materials

The material and how the layers of the mattress are organised can have a huge impact on how comfortable your bed is.

Generally speaking, hybrid mattresses with a softer top layer and a high-count, pocketed coil support layer are good for side sleepers because they combine comfort and support – but foam and innerspring mattresses can be suitable too.

You’ll also typically find that foam-based mattresses with soften with time and may even become less firm during the summer months due to the increased air temperature and humidity levels.

Here’s an overview of each of the major mattress types and how they relate to side sleeping.

Memory Foam

Memory foam mattresses typically include a top layer that moulds to your shape in response to your body heat – whilst the lower layers are made from high density foam to provide support.

For side sleepers, memory foam mattress are typically a good choice because the foam contours to your exact body shape and thus relieves pressure on your hips and shoulders.

However, it’s crucial that you take the time to investigate how dense the lower layers are and the amount of support they can provide for you – especially if you weigh over 200 lbs due to the increased risk of sinking into the support core.

You may also want to bump up the mattress thickness to 12 inches or more – with a comfort layer of at least 5 inches – if you’re a heavier-weight sleeper to provide enough support.

Many mattress brands such as Tempur-Pedic have their own proprietary foam blends that are typically based on memory foam with added ingredients that may or may not add extra qualities – such as increased pressure relief or better temperature regulation.

Side Sleeper Pros

  • Excellent custom pressure relief to avoid aches and pains.
  • Good motion isolation to absorb the movements of your bed partner during the night.
  • High density support layers to keep your spine aligned.
  • Often hypoallergenic to minimise allergies.
  • Look for gel and graphite infused top layers to help you sleep cool.

Side Sleeper Cons

  • Can be difficult to move around and sit up due to the extra give.
  • Some brands sleep hot and cause night sweats.
  • Prone to sagging and indenting with use.


Latex mattresses are similar to memory foam mattresses but typically have a more ‘springy’ feel to them.

This is actually good if you tend to change positions often during the night (combo sleeper) because the added resistance typically stops you from getting ‘stuck’ in the materials.

Natural latex mattresses are also a good choice if you have allergies because the materials are often resistant to allergy-causing dust mites and the materials are often organic.

Side Sleeper Pros

  • Good pressure relief on the hips and shoulders.
  • Bouncy feel to make movement easier.
  • Can sleep cooler than memory foam.
  • Good motion isolation.

Side Sleeper Cons

  • Can be expensive.
  • Still potentially prone to sagging.


Innerspring mattresses are probably the least suitable option if you’re a side sleeper.

Because although the springs can provide good support, the springs can dig into you and create pressure points on your hips and shoulders.

With that said, some of the higher end modern innerspring mattresses have softer top layers to provide more comfort.

As a general rule, you’ll want to look for an innerspring mattress that uses individually wrapped pocket coils, with a high coil count, and a low coil gauge (around 13) to provide the best and most custom level of support possible.

Side Sleeper Pros

  • Good support.
  • Typically cheaper.
  • Good edge support.
  • Usually sleeps cool.

Side Sleeper Cons

  • Can cause pressure on the hips and shoulders.
  • More likely to trap allergy causing dust mites, pollen, and pet dander.
  • Poor motion isolation – easier to get woken up by your bed partner moving.


Hybrid mattresses are arguably the best type of mattress for side sleepers due to their combination of pressure relief and superior support core.

Look for a top comfort layer that’s made of memory foam or latex – depending on your preferences – that’s infused with gel or graphite to help you sleep cool.

To get the best support core, go for individually wrapped pocket coils, with a high coil count and low coil gauge (around 13).

If you’re over 200 lbs, then a hybrid mattress is probably going to be a better choice for you.

Side Sleeper Pros

  • Blends the support of innersprings with the comfort of memory foam or latex.
  • Typically sleeps cool.
  • Hypoallergenic top layer.
  • Good edge support.

Side Sleeper Cons

  • Motion isolation levels may vary.

4: Adjust for Special Requirements

Firmness, support, the structure and materials of your mattress are the most significant factors that will influence how suitable your new bed will be for side sleeping.

But there are also some additional things that you may need to factor in to maximise your comfort levels and they are as follows.


As someone who’s allergic to pollen and dust mites, I can tell you that a flare up during the night is a sure-fire way to ruin your sleep and screw up your energy levels for the next day.

And if you’re in the same boat, then choosing a hypoallergenic mattress could really help because they are designed to prevent allergens from getting stuck in the materials.

You’ll also want to stay away from innerspring mattresses because the cavities are perfect for housing dust mites that can cause year-round allergic reactions.

You might be able to get away with a hybrid mattress if your allergies aren’t that bad – but pure foam mattresses are the way to go overall because dust mites and allergens typically have a harder time penetrating the outer layers.

Natural latex mattresses are also typically resistant to allergens, bacteria, and mold.

Chronic Pain

If you suffer from chronic back, hip, or shoulder pain then you’ll need to take extra care to make sure your mattress has enough pressure relief and support to help with your condition.

You should always talk to your doctor before purchasing a mattress or a new bed to help with your health needs but many folks are reporting that buying an adjustable bed has allowed them to sleep better with chronic pain.

You’ll also want to ensure that your pillows are positioned to keep your spine aligned when sleeping on your side – with the ‘loft’ matching the space between your shoulder and neck.

Temperature Regulation

I tend to sleep hot most of the time.

This means that I have to be careful with memory foam mattresses because they can cause me to heat up quickly if the manufacturer hasn’t placed enough emphasis on the cooling properties of the materials.

If you tend to get too warm at night, then an organic latex mattress might be the best option because they tend to be more breathable.

You could even go for a hybrid mattress with a latex top layer to leverage the better airflow of an innerspring core.

Conversely, if you’re a cooler sleeper then a memory foam mattress might actually be the best option because it may help to trap heat as the material contours to your body.

5: Think About Your Partner

Your partner may have a totally different set of sleeping needs that require a different level of mattress firmness, support, and materials.

Bummer, right?

Not necessarily.

Because in some cases, you can purchase different mattresses than can be zipped together to act as one unit so that you can both benefit from the differing qualities.

Alternatively, you could buy an adjustable bed base with the ‘split’ option so that you can each customise your sleeping position and get different mattresses too.

But if you do end up sharing the same mattress, then you might want to consider a king sized option for more space, and make sure that it has good motion isolation properties to ensure that you don’t wake each other up during the night as you move around.

Is There Anything Else to Consider?

Ok, so I think I’ve just about covered everything that you need to consider when buying a mattress as a side sleeper.

But here are a few more things that you should keep in mind.

Edge Support

Are you the type of side sleeper that tends to hug the side of your mattress?

Then you’ll need a mattress with good edge support so that you don’t end up rolling out during the night or experiencing that ‘falling out’ feeling when you get too close to the edge.

Memory foam mattresses tend to have the worst edge support generally speaking – whilst innerspring mattresses are often then best.

If an innerspring mattress isn’t right for you then a hybrid bed might be a suitable compromise.


One of the benefits of buying a mattress online is the ‘bed-in-a-box’ feature where your mattress will typically come in a neatly compressed package that can be carried up to your room with relative ease.

Sleep Trial

One of the biggest worries if you’re buying a mattress online is that it won’t be comfortable enough.

The best option here is to look for a mattress that comes with a sleep trial so that you can return it if needs be.

Some mattresses come with sleep trials that can last up to 100 nights – which is probably a lot better than just lying on the bed for 2 minutes in the store – because it will give you enough time for the mattress to soften to your body weight and shape.


You can expect your mattress to last between 7 – 10 years if you look after it properly.

And whilst you can get mattress warranties that can last 10 or 20 years – it’s actually more important to choose a warranty that provides the most amount of non-prorated coverage.

Because a prorated warranty means that you’ll have to contribute to the cost of replacing the faulty parts.

In many cases, the warranty period will be split between prorated and non-prorated coverage.

Warranties are particularly important when purchasing a memory foam mattress because they are prone to indenting defects – especially if the foam is very cheap or poorly made.
