Best Pillows for Side Sleepers

Side sleeping is the most popular sleep position. In fact, 63% of us do it.

But if you don’t get your pillow right, it can be a pain in the neck. Literally.

We’ve thoroughly researched and handpicked a small selection of the best pillows for side sleepers.

This is how we rank them…

What Happens to Your Neck When You Sleep on Your Side?

Neck misalignment is a common casualty of side sleeping. The head’s location between the shoulders means that when you lie on your side with your shoulder and hip supporting the body, there is a gap between the mattress and the position your head needs to be in to maintain a straight, aligned spine.

If a pillow does not offer the height and support needed to bridge the gap between the mattress and the optimal head position, it results in headaches and disruption to sleep, as well as pain, stiffness, and fatigue in the neck, shoulders, and back. Poor spinal alignment also causes pinched nerves in the back and neck, leading to long term issues and chronic pain. If you’re looking for a pillow for your neck pain, read this guide.

A good-quality supportive pillow can minimize the strains of side sleeping, ensuring that your spine remains in a neutral position while you sleep your way to an energized morning.

The Importance of a Good Pillow

The quintessential pillow offers a comfortable place to lay the weary head, while also supplementing good sleep posture. It prevents neck and back pain (or relieves existing injuries), helping you to fall asleep faster and stay asleep longer. This improved sleep quality means that the body and mind are adequately revitalized, so you have the energy to tackle each day head-on with vigour.

A bad pillow, on the other hand, can wreak untold havoc on the head, neck, shoulders, back and hips. Everyone’s been there at one stage or another- your idyllic slumber brought crashing back to reality with an aching neck, and no amount of endless tossing and turning will make you comfortable again.

The consequences of an unsuitable pillow go much further than disrupting sleep. Poor head and neck support result in neck and back pain, muscle cramping and impaired circulation. On a long-term basis, the constant sleep interruption will potentially cause exhaustion, anxiety and depression. In turn, these issues lead to problems in every aspect of daily existence, from work, to relationships, to leisure, thus diminishing the quality and enjoyment of life.

What Type of Pillows Suit Side Sleepers Best?

Side sleepers require a full medium-firm pillow to support the neck and keep the spine aligned during sleep. Log and yearner sleepers also benefit hugely from added support in the knee area, so body/knee pillows are an excellent addition to the bedtime routine.

Shredded Memory Foam

The firmness offered by shredded memory foam makes a fantastic moulded surface to support the neck while sleeping. The foam settles around the contours of the head, meaning the neck is buoyed completely without strain, keeping the spine perfectly aligned. The curve of the neck means the air passages remain open and relaxed, reducing snoring. A good shredded memory foam pillow also cools while sleeping. Memory foam retains its shape and size, so doesn’t need readjustment or plumping during the night.

Body Pillows

A body pillow is a long cylindrical cushion that wraps around the body to give added support, especially in the knee area. Available in a range of designs, from regular short cylindrical pillows, to J and U-shaped cushions, body pillows are great for easing strain in the knees and hips while side-sleeping.

Body pillows are used commonly in the later stages of pregnancy to support the bump and ease the tension on pressure points, keeping the spine aligned. They also give invaluable reinforcement to people suffering from arthritis, lumbar pain and pelvic injuries. U-shaped pillows in particular are very beneficial for pregnant women and those suffering with fibromyalgia and osteoporosis.

The downside is that they take up a lot of space (sometimes spreading around the body to fill the entire mattress), so are often impractical, especially for those sharing a bed.

Orthopaedic Knee Pillows

Orthopaedic knee pillows support the top knee while side sleeping, keeping the spine neutral and aligned. A lot more compact than body pillows, they are a good compromise for restricted bed space and are ideal for travelling with. Generally made of memory foam, knee pillows are ergonomically designed and are contoured for maximum comfort. They are especially useful for assisting pregnant women and people suffering from arthritis, spine misalignment, lumbar pain and hip bursitis.

Although they are smaller than body pillows, they are still cumbersome and some people find it quite difficult to turn over without removing the pillow.

Custom Height-Adjustable Pillows

Height adjustable pillows are fantastic for offering a tailored solution that suits all body shapes and sizes. They are usually made by stacking thinner-than-average pillows inside a larger zipped shell. The layers of pillow are added or removed as needed, meaning you get the exact amount of support needed to ensure a terrific night’s sleep.

Pillows filled with shredded memory foam can also have a height-adjustable feature where the user tweaks the height by adding or removing the pillow filling to suit themselves.

Advice for Side Sleepers

Sleep position plays a huge part in determining the quality of your sleep, so it’s imperative to get the balance right. Sleeping on the back is the best posture to ensure that the spine is aligned and relaxed but unfortunately, many people (especially snorers) find back sleeping uncomfortable.

Side sleeping is almost as beneficial to your back. However, there are a few pitfalls to look out for. A normal side sleeping position provides no support for the top knee, meaning it is either resting directly on top of the lower knee, or overreached onto the mattress below. Both positions cause spine misalignment resulting in pressure, strain and fatigue in the knees, hips, back and neck. This affects the quality of sleep and causes ongoing stiffness, pain and frequent waking.

The problems associated with side sleeping are helped by-

  • Sleeping with a pillow between the knees. This supports the top knee, keeping the spine straight and in a neutral position
  • Investing in a decent pillow. A good pillow is often a hugely overlooked factor in the pursuit of peaceful slumber. It matters! The optimal pillow will align the ears, shoulders and hips, promoting a neutral positioning of the spine
  • Find a supportive mattress. A firm, supportive mattress will help your back, but to avoid unnecessary strain, it should also have enough yield to be gentle on the shoulders and hips

Mattress Advice

Just as different pillows complement different sleeping positions, side sleepers also need to consider specific mattress features to optimize their posture. Whoever thought that sleeping could be so complicated?!

A good mattress will have the firmness to support the pressure points of the body without compromising on comfort. Combination mattresses have a traditional spring interior for support, but also provide a pressure relieving top layer which gently cushions the body while you sleep. Advanced mattresses have a gel or latex support layer which moulds to the contours of your body, distributing weight evenly and providing maximum relief and support.

Side sleepers need a medium/medium-soft mattress to ensure that their back and neck are supported, while the hips and shoulders are gently cushioned and sink slightly into the surface of the mattress.

What Does Your Sleeping Position Say About You?

At face value, there are 3 main sleeping positions- front, back and side. However, on closer inspection, there are actually 6, and each come with their own advantages and disadvantages. Remarkably, according to research conducted by Professor Chris Idzikowski, a specialist in sleep assessment, a person’s sleeping posture can also reveal hidden personality traits.

Fetal Position

Fetal position is the most common sleeping pose, with over 40% of people choosing to go back to grass roots and sleep on their side like a baby every night. Interestingly, women are twice as likely to be fetal sleepers than men.

Fetal posture allows the spine to maintain its natural alignment, meaning the pressure points remain neutral and stress-free. Finding a comfortable, relaxed sleeping position is the best way to guarantee a refreshing night’s sleep. Apnea sufferers and snorers favour the fetal position as it eases the symptoms of their malaise. It also improves circulation, meaning better blood flow. However, lying on your side puts undue pressure on the organs of the side you sleep on, so alternating sides regularly is a good idea.

Prof Idzikowski’s study found that fetal sleepers tend to have tough exteriors, but are actually sensitive softies at heart.

The Log

Ever wondered where the phrase ‘slept like a log’ came from? Although the log isn’t as popular as its fetal counterpart, it still makes the cut as one of the top six sleeping positions. Log sleepers crash on their side with both arms resting straight down the sides of the body.

The log is another great snore-minimizer, which also reduces the symptoms of acid reflux. The position aligns the spine optimally, however, because the top leg is unsupported, the knee tends to extend over the bottom leg to rest on the mattress. This leads to rotation of the spine, which causes lower back and hip pain, and is extremely uncomfortable for anyone already suffering with lumbar or pelvic injuries. Sleeping with a pillow between the knees will prevent this strain, giving a more comfortable night’s sleep.

Personality-wise, loggers are laid back socialites who like to follow the latest trends, but sometimes have a gullible nature that can be taken advantage of.

Yearner Position

The Yearner is another side position which is similar to the log, except the arms stretch out from the body instead of resting down the sides. Improved circulation and spine alignment are the biggest benefits of this pose, but as with the log, an unsupported top knee leads to lumbar and hip pain. The arms-out position also puts strain on the shoulders, causing tension and discomfort.

Yearners are often open natured, but sometimes possess a cynical, suspicious streak. They like to weigh up all the particulars of a situation before making a decision or forming an opinion, and once their mind is made up, they rarely change it.

Freefall

Freefalling sounds like a fun pursuit for thrill seekers, but as a sleeping position, it is actually the worst posture for your health. The only benefit to sleeping on the stomach in the freefall position is that it may help to ease digestive discomfort.

The drawback of freefalling lies in the neck positioning. Not many people will sleep with their face pressed directly on to the pillow, so this invariably leads to twisting and turning the head into unnatural positions, resulting in neck strain and soreness. Also, although the body is not on its back, the spine is still misaligned which gives rise to back pain upon waking.

Just as you would imagine an actual skydiver to be, freefallers are friendly and boisterous, with balls to boot! However, underneath their gregarious veneer they tend to be self-conscious and insecure, and they don’t take criticism well.

Soldier

Ten-hut! Soldiers sleep on their backs, arms by their sides with military precision. People who sleep like this are less likely to change positions during the night. This pose is one of the healthiest in terms of spine alignment, and in addition, will ease the onset of acid reflux. Amazingly, it also reduces the risk of wrinkles as it avoids prolonged contact of the face with the pillow.

Unfortunately, back positions aggravate snoring and the symptoms of apnea. Beware of using too many pillows in this pose as it will potentially misalign the neck.

Soldiers generally opt for the quiet life, and don’t like being the centre of attention. However, as you would expect of a real soldier, they set the bar high for themselves and the people they are close to.

Starfish

Starfish is another back pose where the arms splay upwards rather than lying by the sides. As with the soldier, this posture is excellent for maintaining a neutral spinal position, but awful for snorers and apnea sufferers. Another disadvantage is that the position of the arms puts pressure on the shoulders.

Starfishers are helpful and supportive, and their great listening skills make them brilliant friends. They tend to shy away from the limelight, preferring to operate in the background.
