Side sleeping is the most effective positional strategy for reducing snoring, and the right pillow makes the difference between comfortable side sleeping and waking up with a sore neck and shoulder. Not every pillow marketed as “anti-snoring” works well for side sleepers. Side sleeping creates specific support demands that anti-snoring pillows must meet while simultaneously keeping the airway open. Here is what to look for and how to position yourself for the best results.
Why Side Sleeping Reduces Snoring
When you sleep on your back, gravity pulls the tongue, soft palate, and surrounding tissues directly backward into the airway. On your side, gravity pulls these tissues sideways rather than backward, keeping the airway substantially more open. Research consistently shows that positional therapy (switching from back to side sleeping) reduces snoring frequency and volume in the majority of habitual snorers.
Left-side sleeping is slightly preferable to right-side sleeping for snoring and overall health. The left-side position keeps the tongue from falling toward the back of the throat as effectively as the right side, with the added benefit of improved digestion and reduced acid reflux. However, the difference between left and right side sleeping for snoring alone is modest, and either side is dramatically better than back sleeping.
Pillow Height for Side Sleepers
Side sleeping creates a gap between the head and the mattress equal to the width of your shoulder. A pillow that is too thin allows the head to tilt downward, collapsing the airway on the lower side. A pillow that is too thick pushes the head upward, creating a bend in the neck that restricts airflow on the upper side. The correct pillow height fills the shoulder gap exactly, keeping the spine and airway straight from the base of the skull through the neck.
Measure your shoulder width from the outside of the shoulder to the side of the neck while standing. Most adults need a pillow with a loft (compressed height) of 10 to 15 centimetres for side sleeping. Broader shoulders require the higher end of this range. Our pillow size and loft guide covers detailed measurement techniques for finding your exact loft requirement.

Firmness Requirements
Side sleeping anti-snoring pillows need to be medium-firm to firm. Soft pillows compress under the weight of the head, reducing effective loft during the night and allowing the head to sink toward the mattress. By morning, a pillow that started at the correct height may have compressed to the point where the airway is restricted, defeating the anti-snoring purpose. Firm pillows maintain their height throughout the night but can create pressure points on the ear and temple.
The ideal balance is a memory foam pillow with enough density (55 to 70 kg/m³) to maintain loft while still contouring around the ear and cheekbone. Contoured memory foam pillows with an ear depression cut into the surface solve the pressure problem: the main pillow body stays firm for support while the ear sits in a recessed area that eliminates direct pressure.
Shoulder Cutout Design
Some anti-snoring pillows designed for side sleepers include a shoulder cutout: a curved notch in the bottom edge of the pillow where the shoulder fits. The cutout allows the pillow to sit closer to the neck without the shoulder pushing it away, providing better neck support and keeping the airway straighter. Without a shoulder cutout, many side sleepers unconsciously scrunch the pillow under their neck, which creates an uneven surface and inconsistent support throughout the night.
Orthopaedic cervical pillows often include shoulder cutouts as a standard feature because cervical alignment and airway alignment overlap significantly. A pillow that keeps the cervical spine neutral also keeps the airway in its most open position, making cervical pillows a dual-purpose option for snorers who also experience neck pain.
Preventing Back-Rolling During Sleep
Many side sleepers start the night on their side but roll onto their back during deeper sleep stages, which is when snoring typically occurs. Anti-snoring pillows with a raised centre section or a central ridge discourage unconscious back-rolling by making the back-sleeping position subtly uncomfortable. The sleeper rolls back to their side without fully waking.
For persistent back-rollers, a full-length body pillow placed behind the back provides a physical barrier against rolling. Hugging a body pillow in front also stabilises side sleeping by giving the upper arm and leg something to rest on, which reduces the rotational force that pulls the body toward the back position. Combining an anti-snoring head pillow with a body pillow is the most effective non-medical approach for positional snoring.

Pillow Materials That Help
Latex pillows offer excellent side-sleeping anti-snoring performance. Natural latex is inherently responsive and maintains its shape better than most foams over time. A solid latex pillow in medium-firm does not compress under head weight the way memory foam or polyester fill can, providing consistent loft and airway support night after night. Latex is also naturally breathable and resistant to dust mites, which reduces nasal congestion that contributes to snoring.
Avoid feather and down pillows for anti-snoring use. While comfortable, down and feather pillows compress too readily under side-sleeping head weight and cannot maintain the consistent loft that airway support demands. The fill shifts away from pressure points during the night, creating valleys that allow the head to sink and the neck to bend. Down pillows excel at comfort but perform poorly at the structural support that anti-snoring positioning requires.
Testing Whether Your Pillow Works
Ask your partner to observe (or use a snoring tracking app) for two to three weeks after switching pillows. Record your sleeping position when you fall asleep and when you wake up. If you consistently stay on your side but snoring persists, the pillow height may need adjustment or the snoring cause may not be positional. If you start on your side but wake on your back, the pillow is not effectively discouraging back-rolling and you may need to add a body pillow or try a design with a more prominent centre ridge.
