What are the benefits of side sleeping?

Side sleeping is one of the most popular positions, and the benefits help to show why. Side sleepers can expect to enjoy some or all of the following benefits;

  • Less back pain - Back pain can be debilitating and finding any way to minimise this is always recommended. One of the leading causes of back pain is sleeping in awkward positions. Sleeping on your side relieves the pressure applied to your spine that sleeping on your front can cause, and side sleeping has been shown to reduce this.
  • Minimises the risk of sleep apnea - Sleep apnea is a breathing disorder that tends to impact older people or those suffering from obesity. It is when your breathing is interrupted while you sleep. Sleeping on your back can cause your tongue to obstruct your airways and cause snoring or sleep apnea; sleeping on your side minimises this risk.
  • Better gut health - Many people don't realise the critical role that body position plays in your internal health. Side sleeping has been shown to improve issues such as heartburn, bloating, and constipation.
  • Improved brain efficiency - Studies have shown that the brain's ability to remove waste is improved when sleeping on the side.
  • Better for pregnant women - Pregnant women may find side sleeping more comfortable than sleeping on their back. It also stops the baby's weight from resting on the vein that carries blood to the mother's heart from her legs.

How to choose the best pillow for side sleepers

Now that you know a bit more about the benefits of side sleeping, and the best pillows for different categories, you might want to know how to go about choosing the best pillow for you.

Take a look at the factors below for more information on what side sleeper pillow will suit you.


The materials of the filling and cover will play a big part in what pillow you might want to buy. Some offer easier cleaning, some will provide anti-allergy properties, while others will be better for warmer nights.


There is an old saying that you "get what you pay for." While you will be able to invest in long-lasting, high-quality side sleeper pillows, there are plenty of great budget options to choose from as well.

Budget pillows can be a great way to test the water and find the perfect pillow that suits you.


The loft of a pillow is the height when it is lying flat on a bed. Thinner pillows are better suited to those who sleep on their back or front, while a higher loft will help support your head and align your neck and spine when sleeping on your side.


Your pillow shape will also make a big difference to your comfort levels, so it is worth looking at the options. Traditional pillow shapes will always prove popular as they are aesthetically pleasing and well-suited for providing the support needed.

Other options worth looking at include ergonomic pillows and v-shaped pillows. These different options can offer support and may suit different people and circumstances.

Level of firmness

Mid to firm pillows are better suited to side sleepers because of their support. A slightly elevated head helps to align the neck with the spine, minimising the risk of aches and pains.

What are the best pillow materials for side sleepers?

Alongside the other decisions you need to make when buying a pillow, you should think about the filling material you want. There are many great choices, with some more suitable for side sleeping pillows than others.


Down is the undercoat of birds, used to create a soft, fluffy filling for pillows that adapt well to the shape of the head and neck. It is a long-lasting filling that can even be replaced or topped up.

Unfortunately, a down pillow can be an expensive option that is prone to flattening after prolonged use. They are great for the winter but can be quite warm for the summer. They are not suitable for vegan use or for people with allergies.


Feather pillows are common, thanks to their affordability. They mould your head and neck shape easily and are lightweight but can face similar issues as down pillows do with flattening and heat retention. Feathers can start to poke through after time as well.

Memory foam

A memory foam pillow is ideal for side sleeping because it provides excellent support and firmness and moulds to your shape.

Memory foam is made using compounds including polyurethane and won't clump or go flat like other pillows. They can be pretty warm during the summer and are relatively expensive compared with alternatives.

Shredded memory foam pillows are also an option that is cooler than a standard memory foam pillow.


Hollowfibre pillows are ideal if you’re on a budget. They offer a great level of support, and you can choose from differing firmness levels. These pillows contain a light and airy centre, making them comfortable to sleep on all year round.

The synthetic filling also makes these a great choice for anybody who has asthma or allergies, including hayfever.

Side sleeping tips to sleep comfortably at night

As well as choosing the best pillow, here are some other suggestions that may improve your sleep.

Select the right the mattress

Picking the right mattress is as essential as choosing the right pillow. Side sleepers are advised to go for medium-firm to medium-soft mattresses that will help to cushion the points of impact. Back or stomach sleepers are better with firm to medium-firm mattresses as their body weight is spread over a greater area.

Consider using a pillow between the knees

Side sleeping with the right pillow will help align your spine and reduce aches and pains. Some people also like to sleep with a pillow between their knees as this helps align the hips and pelvis during sleep, reducing the strain on muscles and ligaments.

Get a mattress topper

Mattress toppers are a great way to improve the comfort of a mattress by providing an extra bit of cushioning. They are also a great way to protect the mattress from stains.
