Some people prefer to sleep flat on their fronts or backs, whereas others prefer to sleep on one side. Most side sleepers usually have a preference between the left and right sides. However, regardless of which side, side sleeping inevitably puts added pressure on the shoulders and hips.
The best mattress for side sleepers is one that will provide the perfect balance between support and necessary cushioning to keep the spine correctly aligned. An incorrect mattress may lead to shoulder and back pain and many nights of restless sleeping. It is essential to do your research to suit your personal needs and preferences.

How Sleeping On Your Side Affects Your Sleep
It has been well documented that sleeping on your side, as well as being the predominant sleeping position✓ in adults, has many health benefits. Interestingly, it has been shown✓ that children sleep equally as much on the side, back, and front, but tend to spend more time in the side position as they get older. This preference also increases with an increased body mass index (BMI)✓.
Health Benefits Of Side Sleeping Include:
- Opened airways and reduced snoring. Restricted airway passages or obstructive sleep apnea (OSA) can cause snoring, as well as lead to more serious conditions like hypertension, heart disease, stroke, and diabetes.
- Reduction in heartburn/acid reflux. Studies✓ show this to be true when sleeping on your left side, specifically. Sleeping on the right side has been shown to worsen the problem!
- Safety of unborn baby✓. Well, research✓ is varied on this one. However, doctors do generally suggest sleeping on the left side, especially as time goes on.
- Correct spinal alignment. This is of course dependent on your body and spine getting the proper support where needed.
Spine Alignment
Back pain and other issues can result from the spine deviating from a neutral (straight) position. Side sleeping with legs straight is believed to be the second-best sleeping position for your neck and back (second to lying flat on your back). A contouring mattress will ensure both the best cushioning and support in the right places so that the spine is maintained in this neutral position. A higher loft pillow for the head and a thin firm pillow between the legs will also help to keep the spine aligned.
Side Sleepers With Shoulder Pain
One disadvantage to side sleeping is the possibility of shoulder pain. Whilst with the correct support in both pillow and mattress, side sleeping shouldn’t be the cause of shoulder pain, it may exacerbate an existing injury or problem.
Shoulder pain as a result of side sleeping is most often the result of the shoulder collapsing into the mattress as well as pushing up towards the neck, causing misalignment. This puts additional stress on the area but can be avoided with a pillow high enough to keep the head level with the shoulders, and a mattress firm enough so that the shoulder does not sink in too deep but soft enough so that there is sufficient cushioning.
As for existing issues, if not sleeping on the problematic side is impossible, and problems persist, it may be a good idea to try a thick mattress topper best suited for side sleepers.
Side Sleepers With Back Problems
As with shoulder pain, side sleeping shouldn’t be the cause of back pain. A good way to test if your mattress is to blame is to pay attention to when exactly you are experiencing the pain. If it is the first thing in the morning, and a 15-30 minute stretch alleviates the pain somewhat, then it’s a good sign that your mattress may be the problem. Battling to fall asleep or waking up frequently during the night may also point in this direction.
A mattress that does not contour to the shape of the body or provide enough support in necessary places can result in the misalignment of the vertebral column and pressure on the spinal joints. This may cause back problems for side sleepers or exacerbate existing back problems. The best mattress for side sleepers with back problems is one that will offer the correct balance of softness and even full-body support.
Fun fact!
A study in the UK showed 36% of people sleep on their left side. These ‘Lefties’ are likely to be between the age of 45-54 years and are also more likely than any other sleeping position to be degree-educated. The study showed 34% of people sleep on their right side. ‘Righties’ are more likely to be between the age of 35-44 years, heavier smokers than any other sleep position, and big caffeine fans.
Which Mattress Firmness Is Best For Side Sleepers
Mattress firmness is usually rated on a scale of 1 to 10, with one being the softest, and ten being the most firm, like a futon. For side sleepers, the mattress firmness will determine how much cushioning there is under the
pressure points.
- A “medium” (somewhere between a soft and medium-firm) firmness is typically best for side sleepers as it offers both equal amounts of pressure relief and necessary support.
- Bear in mind that a “medium” may differ depending on the brand so best to look at a range between a 5 and 7 on the scale.
- Other factors for side sleepers to take into account when deciding on mattress firmness include personal preference, body weight, body type, and mattress type.
Which Type Of Mattress Is Best For Side Sleepers
There are several types of mattresses on the market today, each having its pros and cons for side sleepers. The best mattress for side sleepers will offer the perfect combination of cushioning and support in the right places. The most commonly available mattresses are listed below. It’s important to understand the differences so that you can make the most informed decision for your purchase. It’s also important to note that specific mattress models across brands may vary slightly in materials, construction, and unique features.
- Innerspring: These mattresses have a support base of steel coils with thin layers of foam or latex, or both, on top. Innerspring mattresses are generally firmer, but can be suitable for side sleepers as long as there are sufficient layers of cushioning to offset the stiffness of the springs.
- Hybrid: A hybrid mattress uses two types of support structures, typically an innerspring support system, and memory foam or latex support system. The combination of these systems essentially results in a “best of both worlds” mattress, offering contouring comfort, stable body support, pressure relief, and proper alignment for your spine. Hybrids can therefore be a good alternative to innerspring mattresses for side sleepers due to this mattress’s ability to relieve pressure as well as provide enough cushioning.
- Latex: A latex mattress is constructed with either natural or synthetic latex. These mattresses are known for their soft, springy feel, as well as their durability. They are typically made from foam and latex, and can be ideal for side sleepers as, like foam, latex conforms closely to the body, relieving pressure, and providing adequate cushioning of certain areas.
- Airbed: An airbed mattress is an inflatable mattress usually made from vinyl, plastic, or rubber. The firmness of these mattresses can be adjusted by filling with, or removing air. Adjustable air mattresses enable you to adjust and customise your comfort. For side sleepers who aren’t sure what their preferred firmness is, or would just like a change, this mattress offers customisable firmness. Models that allow for adjustability in different zones may be advantageous too as side sleepers can adjust the firmness under the shoulders and hips to keep the spine aligned.
- Foam: A foam mattress is usually made using two types of foam – polyfoam, in the base support layer, and memory foam for the top comfort layers. Memory foam mattresses contour closely to the body cushioning areas like shoulders and hips, providing the comfort and pressure relief necessary for the correct spinal alignment. Side sleepers who opt for this mattress should make sure they choose one with a substantial support layer so that the mattress doesn’t sink and sag.
Accessories Important For Sleeping On Your Side
The addition of sleep accessories such as pillows and mattress toppers can make sleeping more comfortable. Knowing what exactly to look for in these sleep accessories is helpful for side sleepers.
- Head pillow for side sleepers: The correct pillow for your head is necessary for optimal spinal alignment. A medium or high loft pillow should lift your head enough to keep both your head and neck aligned with your spine. This relieves pressure on the neck and shoulders.
- Knee pillow: Knee pillows (or softer regular pillows) can also be used to further customise your sleeping position, and aid in keeping the spine aligned and reducing pressure in the hips and legs.
- Mattress toppers: A mattress topper sits on top of your mattress providing additional contouring and pressure relief. For side sleepers, a memory foam topper or latex topper may be your best option. These materials offer both support and cushioning which alleviates pressure and keeps the spine aligned. Worth noting, however, that a mattress topper will not compensate for an old unsupportive, or broken mattress. If this is the case, best to invest in a new mattress.
What Mattress Features Are Important For Side Sleepers
When sleeping on your side there is added pressure on the shoulders and hips and it's, therefore, a good idea to take the following factors into consideration when shopping for a new mattress.
- Mattress Type: For side sleepers, your ideal mattress should most importantly offer you sufficient contouring and full-body support. Other considerations include factors such as temperature regulation, motion isolation, and pressure point relief. Being clear on your priorities and preferences will guide you when looking for the best mattress type.
- Contouring: How well a mattress fits to the unique shape of your body will determine how well it contours. A good contouring mattress for side sleepers will combine firm support as well as plush cushioning for the shoulders and hips, ensuring optimal spinal alignment.
- Quality Materials: High-quality materials result in a mattress that is more durable, comfortable, and lasts longer, however, they may be attached to a heftier price tag. Cheaper mattresses can be less durable and may offer less support over time.
- Firmness Level: For side sleepers who require a balance of soft cushioning for the shoulders and hips and support to keep the spine aligned, a soft to medium-firm mattress is usually best. This comes down to personal preference, as well as other considerations such as weight. Heavy people may prefer to opt for a firmer mattress, whilst lighter people, a softer mattress.
