The Best Mattress for Side Sleepers: Find Your Fit

Do you tend to sleep on your side? You’re not alone. With most adults sleeping on their side, it’s one of the most popular sleeping positions in the UK!

But how do you know if you’re sleeping on the right mattress for you? The way you’re positioned throughout the night can have a big impact on your quality of sleep as well as your spine health. That’s why it’s so important to find a fully supportive mattress that meets your needs.

From mattress firmness to motion transfer, we’re exploring the different types of mattresses and their benefits to help you find the right mattress for you.

So, let's find the best mattress for side sleepers and start your journey towards perfect sleep.

Is it Good to Sleep on Your Side?

Firstly, let’s look at the pros and cons of sleeping on your side and what it means for your health and spine alignment.

Did you know, sleeping on your left side is better for your body!? Here are some of the health benefits of sleeping on your left side;

  • It helps to prevent snoring
  • It helps to clear your lymph nodes
  • It can improve digestion
  • It can prevent heartburn
  • It can improve circulation
  • It encourages healthy spine alignment
  • It can reduce sleep apnoea by opening your airways
  • It is the most comfortable sleeping position for pregnant women


Unfortunately, like most good things, side sleeping has its drawbacks;

  • It can produce numbness in one arm
  • Sleeping on your side puts pressure on your shoulders
  • It can also put pressure on your hips 

However, most of these issues can be resolved with the right mattress.



What Type of Side Sleeper Are You?

Within the side sleeper profile there are several different positions. Usually side sleeping refers to one of the following positions;

The Log Position

You favour the log position if you sleep on your side with a straight back and arms and legs extended. This position is better for spine alignment but can cause shoulder discomfort.

The Foetal Position

The foetal position is a common sleeping style, especially among women. This is when you curl into a ball when sleeping on your side. This position elongates the spine; however, it can put pressure on your lungs if you sleep tightly curled.

The Yearner Position

This is a variant of the log position, the difference being that your arms are extended out in front of you.

However you sleep, there’s a mattress out there for you.

How Firm Should a Mattress be for a Side Sleeper?

The ideal mattress firmness for side sleepers is medium to medium-soft. This is because firmer mattresses can be uncomfortable on pressure points such as hips, ankles and shoulders if you stay in one position throughout the night.

A softer, yet supportive mattress cushions these areas while helping to retain good spinal alignment.

Your Weight

When choosing your next mattress, you need to consider your weight when determining the perfect firmness for you. Usually, the heavier you are, the firmer your mattress will need to be to provide optimum support.

The firmness of your mattress does depend on individual preference, but you can follow these loose guidelines;

  • Under 10 stone- soft
  • Between 10-16 stone- medium
  • Over 6 stone - firm 

Mattress Depth and Density for Side Sleepers

Mattresses come in a range of depths which change the feel and comfort level of the mattress. The deeper the mattress, the more you can experience that ‘sinking’ feeling. The ideal mattress depth for you will be dependent on your weight and sleeping position.

Therefore, a medium to deep depth would suit a side sleeper.

For memory foam mattresses, density refers to the quality of memory foam used. The denser the foam, the more supportive it is.

Which Type of Mattress is Best for Side Sleepers?

Now we’ve explored what to look for in a mattress, it’s time to turn our attention to some different types of mattresses and find out which ones work best for side sleepers.

Memory Foam Mattress

Memory foam is ideal for side sleepers thanks to its soft, yet supportive cushioning and support. Memory foam moulds to the shape of your body in contact with pressure and heat to ensure your spine lays flat along the bed and is properly aligned.

By spreading your body weight evenly, memory foam layers can ease pressure on hips and joints, allowing you to sleep comfortably all night long.

Innerspring Mattress

Innerspring mattresses are supportive and breathable. However, some spring mattresses can feel uncomfortable for side sleepers as the springs put pressure on shoulders and hips when lying down for extended periods.

Pocket Sprung Mattress

Pocket spring mattresses are more suitable for side sleepers as they provide targeted support through individual pocketed coils. This is helpful when sharing a bed with someone of a different weight as you can both be supported independently.

Is a Hybrid Mattress Good for Side Sleepers?

A hybrid mattress could be the key to the perfect night’s sleep for side sleepers. By combining the support and breathability of a spring base with a cushioning memory foam top layer, side sleepers can experience the best of both worlds.
