Best Pillow for Side Sleepers UK
Reviews & Comparison

Last Updated on December 3, 2021



Our Choice




Sleeping on your side is the most common sleeping position in the world. When you’re a side sleeper, you need a mattress that will provide adequate cushioning and support to promote even spinal alignment. Choosing the right mattress will help reduce pressure points all over your body, including areas such as the shoulders and hips.

With that said, the appropriate mattress isn’t the only essential since a pillow can make your sleeping experience better or worse. In general, side sleepers need thicker options that can fill the space beneath their head and neck to provide proper support.

For example, a product that’s too thin won’t be able to provide enough cushioning. Simultaneously, excessively thick items might cause added pressure points to develop due to the interference with the spinal alignment.

We understand that you might not think of posture as something to consider during sleep, but if you sleep on your side, it’s crucial to keep your head, neck, and back aligned to avoid pain and stiffness. Choosing an option with the right height and firmness can improve the quality of your sleep and the pain-free mornings.

But how can you choose a quality product that fits the bill and checks all the boxes? There are many options on the market – from high-quality products from reputable companies to cheap Chinese products that we wouldn’t recommend to our worst enemy.

That’s why we created LightSleeper – to help you choose the product that is right for you and you alone and help you make that choice along the way. Companies can never pay to feature their products on LightSleeper, nor we are getting paid to recommend one product over the other – we are an independent resource, and we only recommend products that have passed our tests, and we feel that they are the best in their category.

So let’s see what we think are the best pillows for side sleepers in the UK and why:

How to choose the best pillow for side sleepers?

choose best pillow for side sleepers

When you’re searching for a compatible pillow for side sleepers, there are multiple features you need to consider to find the best-suited option for yourself. These factors are the following:


As a side sleeper, you don’t want a pillow that feels too soft because it will most likely sink too much beneath your head, which can lead to alignment issues and added pressure. However, you don’t want something incredibly firm either since you might experience discomfort around the neck and shoulders. We highly recommend staying between the medium-firm and firm options because they provide the perfect balance of contouring and support you will need when sleeping on your side.


Materials are also essential in your pillow choice. You need to consider both the cover and inner components since they can wide range of qualities and issues. Be careful with what you choose. Don’t consider only your sleeping position but also your body shape and weight. The right materials can offer a longer lifespan and better overall performance.


The thickness or the loft is an incredibly crucial aspect of your choice because most people who sleep on their side will require medium to high loft pillows to receive enough cushioning for the head and neck without sinking too low. With that said, if you don’t know what’s the most suitable option for you, we advise you to try an adjustable product.


This feature is important since some items will compress over time, which means they will flatten and feel less comfortable. Your best bet is to regularly fluff your pillows to give them a fuller shape. With that said, memory foam and latex pillows maintain their shape and typically provide the best support.

Pressure Relief

People sleeping on their sides often feel pressure in the shoulders and hips if their mattress isn’t supportive enough. Pressure can build up from improper use of pillows just as much around the neck and shoulders. Thus side sleepers usually need a supportive item that will also contour their body.


Just like with everything else, the price can vary depending on the pillow’s components. If you’re on a budget, polyfoam, down alternative, and feathers typically have the lowest price points. But if you are willing to spend the extra buck, opting for memory foam, latex, down, and buckwheat pillows is the better option.

Bottom line

In general, side sleepers essentially need thicker products with a firmer feel to ensure that the space between their head, shoulders and neck is supported. If you aren’t adequately supported, that can lead to neck pain and result in consistent poor-quality sleep.

You know it’s time to change your pillow with has flattened. If you don’t know where to start warranty can be a good indicator of how long a product can last. You should consider a few things when shopping for your perfect pillow that includes materials, firmness, thickness, support, price, etc.
