How common is side sleeping?

Side sleeping is one of the most common sleeping positions in Australia, and many people alternate between sleeping on their side and their back throughout the night.

In a Bedbuyer sleep survey involving 1,160 respondents, approximately 30% reported sleeping exclusively on their side, whilst around 36% reported sleeping on both their back and side. A further 20% reported sleeping in all three main positions (back, side, and front).

These findings suggest that side sleeping forms part of the normal sleeping routine for a large proportion of Australians.

This is an important consideration when choosing a mattress, as many people need a sleeping surface that accommodates more than one sleeping position.

Is side sleeping the healthiest sleeping position?

Side sleeping is often recommended by chiropractors, physiotherapists, and other health professionals, as it can offer several benefits for comfort, spinal alignment, and general health.

For some people, side sleeping may help reduce snoring and improve breathing during sleep. Sleeping on the left side may also help reduce symptoms of acid reflux, as this position can make it more difficult for stomach acid to travel back into the oesophagus.

However, the most suitable sleeping position will vary between individuals. Factors such as personal preference, body shape, mattress comfort, and existing health conditions, including back pain, can all influence which position is most comfortable.

For example, some people may find back sleeping more comfortable, whilst others may benefit from alternating between their back and side throughout the night. Certain medical conditions or post-surgical situations may also require a specific sleeping position, including sleeping in a more upright position.

Ultimately, there is no single sleeping position that is best for everyone. The most important consideration is finding a comfortable position that provides adequate support and allows for restful, uninterrupted sleep.

How to choose the best mattress for side sleepers

1. Choose the right firmness

Mattress firmness is one of the most important considerations for side sleepers. Generally speaking, a medium or medium-soft mattress is a good starting point, as these tend to offer a comfortable balance of pressure relief and spinal support.

However, mattress firmness ratings should only be used as a guide. A mattress described as ‘Medium’ by one manufacturer may feel noticeably firmer or softer than a ‘Medium’ mattress from another brand.

At Bedbuyer, we independently assess mattress firmness during our testing process, using a scale from 1 to 10 (with 10 being the firmest). This helps consumers compare different mattresses more consistently.

2. Look for good pressure relief

Pressure relief is particularly important for side sleepers because much of the body’s weight is concentrated around the shoulders and hips.

These areas contain prominent bony structures, including the shoulder joint and pelvis, which can experience uncomfortable pressure when lying on a mattress that is too firm.

A suitable mattress should allow the shoulders and hips to sink gently into the comfort layers, helping to distribute body weight more evenly and minimise pressure points.

Materials such as memory foam, latex, and specialised comfort foams can provide effective cushioning, although the overall mattress construction is more important than any individual material.

3. Maintain healthy spinal alignment

Although cushioning is important, side sleepers still require adequate support to maintain healthy spinal alignment.

When lying on your side, your spine should ideally remain in a relatively neutral position, without excessive bending or sagging through the waist and pelvis.

A mattress that is too firm may prevent the shoulders and hips from sinking sufficiently, whilst one that is too soft may allow the pelvis to sink too deeply.

The ideal mattress provides enough cushioning to accommodate the body’s natural contours, whilst maintaining sufficient support through the rest of the body.

4. Consider your other sleeping positions

Many Australians don’t remain in one sleeping position throughout the night. As our survey demonstrates, sleeping on both the back and side is particularly common.

This is one reason why medium feel mattresses are often a sensible choice. They can provide enough cushioning for side sleeping, whilst maintaining sufficient support when lying on your back.

For back sleepers, a mattress that is excessively soft may allow the pelvis to sink too deeply, potentially affecting spinal alignment.

If you regularly alternate between sleeping on your side and back, a mattress with a balanced medium feel may offer the best overall compromise.

5. Consider adjustable firmness

Mattresses with adjustable firmness can be particularly useful for side sleepers who are unsure of their preferred comfort level.

Some mattresses allow users to rearrange internal comfort layers, flip the mattress over, or add a separate mattress topper to create a softer sleeping surface.

This flexibility can be valuable because mattress comfort is highly individual. Factors such as body weight, body shape, and personal preference can all influence how a mattress feels.

Several mattresses in our top 10 list offer adjustable firmness, allowing users to fine-tune their comfort without purchasing an entirely new mattress.

Final thoughts

Choosing the best mattress for side sleeping involves finding the right balance between pressure relief and spinal support.

Whilst medium and medium-soft mattresses are generally a good starting point, there is no single firmness level that will suit everyone.

Body weight, body shape, sleeping habits, and personal comfort preferences should all be considered when making your decision.

All ten mattresses in this article have been independently tested by Bedbuyer, and each offers characteristics that make it a suitable option for side sleepers.
