Best Mattress For Side Sleepers UK (2022)

There are numerous health benefits to sleeping on your side.

But, there are also quite a few drawbacks as side sleeping creates tension in certain parts of your body.

This is why choosing the right mattress is so important 📢

Here, we'll give you an overview of how side sleeping affects your rest before deep-diving into what to pay attention to when buying a new mattress for side sleeping.

Health benefits of side sleeping

There are numerous health benefits associated with sleeping on your side.

These include 👇

Reduced snoring

Sleeping on your side allows your airways to remain open.

This helps reduce snoring.

It also helps control the effects of sleep apnoea, which can be detrimental to your sleep and your overall health and quality of life.

Better digestion

Numerous health studies show that sleeping on your left side helps digestion and decreases heartburn. 🍔

Our organ placement is largely asymmetrical, and sleeping on the left side helps gravity take over in transporting waste through the colon.

Comfort during pregnancy

Side sleeping is generally recommended for pregnant women as it allows for increased blood flow and is thought to result in better foetal health.

It's also much more comfortable 😴

Optimal spinal alignment

If you have the right mattress, side sleeping results in optimal spinal alignment.

This is better for your health and eliminates the causes of back and neck pains.

Drawbacks to side sleeping

Despite the above-mentioned health benefits, there are also a few drawbacks to side sleeping.

These include 👇

Improper spinal alignment

Side sleeping on the right mattress allows for optimal spinal alignment.

But, sleeping on your side on a mattress that's not perfectly designed can lead to improper spinal alignment.

This results in tension and lower back pain 😩

The right mattress will allow your hips and shoulders to sink in more deeply, allowing your spine to remain straight at all times.

Shoulder pain

Side sleeping places more pressure on your shoulders, which can lead to or worsen shoulder pains.

This is only if you don't have the right mattress.

If your mattress doesn't allow your shoulders to sink in deeply enough, it will push your shoulders up towards your neck.

This results in a misalignment of your anatomy.

Similarly, if your mattress is too soft, your shoulders will sink in too deeply, again resulting in misalignment.

The right mattress, together with the right pillow, can assist in creating alignment and leaving you tension-free.

The Simba Hybrid, for example, is a medium-firm mattress with great orthopaedic support that helps alleviate tension.

Back pains

Side sleeping shouldn't cause back problems - but sleeping on a bad mattress can cause or worsen existing back pain.

How do you know if your mattress is at fault?

If you wake up with back pain that generally disappears within an hour of getting up or after some stretching, then your mattress might be to blame.

It could be too firm or too soft, both of which lead to improper spinal alignment.

Pelvic rotation

Side sleepers may suffer from the effects of pelvic rotation.

This results from the displacement of the back muscles and the lumbar spine.

A rotation happens when you turn the upper body in the opposite direction of the lower body.

This can be quite painful 😱

You can prevent pelvic rotation by clamping a pillow between your legs while you sleep.

Choosing the right mattress with the proper support structure can also help.

Choose the right mattress for side sleeping

Luckily, all the negatives to side sleeping are usually caused by an incorrect mattress or pillow 🥳

The right mattress will alleviate these drawbacks and ensure a tension-free sleep in the side position.

Let's look at what you should pay attention to when buying the right mattress for side sleeping.

If you've done some reading on mattresses, you'll have seen the term "point elasticity" thrown around.

But what exactly does this mean?

Point elasticity measures the ability of materials to compress at a specific point without affecting the rest of the mattress.

If a mattress has high point elasticity, for example, it means that you can put a very heavy dumbbell at one point and only have the mattress sink in at that point 🏋️‍♀️

The rest of the surface will remain unaffected.

If you've read the above section on stability and support, you'll know that this is exactly what you need if you're a side sleeper.

Your hips and shoulders (the dumbbells in this scenario) will need to sink in more deeply, but the rest of the mattress should remain unaffected.

Point elasticity is influenced by the materials used and the composition of the mattress.

But, you can rest easy in knowing that all the mattresses we recommend have exceptional point elasticity.

The Simba Hybrid, for example, responds extremely well at the point where pressure is exerted - with no impact on the rest of the mattress.

Great for couples

Mattresses with high point elasticity also generally have low motion transfer.

This means that you can happily share your bed with a partner and not be disturbed by any tossing and turning.

That said, we still recommend that couples choose larger mattress sizes.

This ensures both partners have enough space to sleep comfortably.

Mattresses in king or super-king sizes are preferable 👌

Our mattress size guide can help you choose the right size for you.

If you have a mattress that offers good stability and support, has high point elasticity, and allows for pressure relief, then you've already made a good choice.

The degree of firmness you choose is often simply a matter of personal preference.

But, your size, body weight, and sleeping position influence which level of firmness will be more suitable for you.

Firmness for side sleepers

In general, we would recommend a slightly softer mattress for side sleepers.

On our Sleep Hero firmness scale, this would be any mattress with an average firmness of about 4 - 6 (where 1 is the softest and 10 is the firmest).

These are generally softer or medium-firm mattresses.

Firmer mattresses often don't allow for sufficient sinkage in the hip and shoulder areas, which will prevent optimal spinal alignment.

You can, however, find some firmer mattresses that still allow for enough sinkage, like the Nectar memory foam mattress.

Consider your size and body weight

Your build, size, and body weight will also influence which level of firmness is the best.

If you are a bigger or heavier person (above 90 kg and especially if you're above 130 kg), you should choose a slightly firmer model.

Mattresses with a firmness level of 6 - 8 on our scale, like the Nectar mattress, will work well.

This is because people who are slightly heavier will sink into the mattress more deeply, and will need a mattress that's firm enough to still offer sufficient support.

Spring mattresses are particularly well-suited to heavier people as they offer greater firmness and stability.

You can always choose a hybrid mattress that features top layers of memory foam, a mattress with a quilted pillow top, or a spring mattress with a memory foam mattress topper to achieve the same comfort level as with a foam mattress.

We really like the Simba Hybrid mattress.

Make use of risk-free trial periods

The only way to really determine whether a mattress's firmness is right for you is by trying it out.

This is where risk-free trial periods are so handy 💵

Most bed-in-a-box mattress brands, which we recommend, offer a minimum of a 100-night trial period.

Some, like the Simba Hybrid, come with a 200-day risk-free trial period.

The Nectar mattress even offers a revolutionary 365-night trial 🗓

If you're not fully satisfied, you can return the mattress - free of charge - and receive a full refund.

This way, you'll be guaranteed to find the most comfortable mattress for you.

In addition to choosing the right mattress, side sleepers will also need to pay attention to their choice of pillow.

Even the best and most expensive mattress will be useless if your head isn’t properly supported 🤷‍♀️

A bad pillow can easily result in severe neck pain.

For side sleepers, the best pillow will cradle the space between your neck and the mattress while still offering sufficient comfort and support for your head.

The pillow's height plays an important role here.

Look at the below table as a general guideline:

Side sleepers generally require a high-loft pillow that allows for upper spinal alignment.

You also want a pillow that supports your head and neck well but isn't too firm, as this will create unnecessary pressure and tension.

Pillows made of latex or memory foam are particularly suitable ☁️

These materials ensure that the pillow adapts well to the shape of your head and that pressure is distributed well.

Height-adjustable pillows

We really like pillows with interchangeable layers.

These give you some playroom and allow you to adjust the height and firmness of the pillow to suit your specific needs.

We've recommended some of our favourite customisable pillows below.

Our favourite pillows:

Side sleepers need the right mattress to provide optimal comfort and support.

Mattress material may play a role.

Latex mattresses and memory foam mattresses are excellent choices.

You can also opt for a firmer spring mattress with ample cushioning to provide the right feel.

Ultimately, what's important is that the mattress is firm enough to support your body but soft enough to allow your hips and shoulders to sink in more deeply, resulting in optimal spinal alignment.

Medium-soft is generally the way to go.

Also, pay attention to stability and support, high point elasticity, and pressure distribution.

Luckily, all of the mattresses we recommend meet these criteria.

This ensures that you'll find the best side sleeper mattress and enjoy a good night's sleep, night after night.
