Best Pillow Position to Stop Snoring (and the One That Makes It Worse)
Short answer
- Sleep on your side with the neck straight — 10–14cm of firm loft.
- Raise the whole torso 10–15cm, not just the head.
- Never stack two pillows under the head; it bends the airway shut.
- Use a body pillow front and back to stop rolling over.
Pillow position is the cheapest snoring intervention there is, and the one most people get wrong. The instinct when someone snores is to prop their head higher — which, done with ordinary pillows, folds the chin towards the chest and narrows the very airway you're trying to open. The goal is not height. It is alignment plus a gentle whole-body incline.
Why position changes the noise at all
Snoring happens when relaxed tissue in the throat vibrates as air squeezes past. On your back, gravity pulls the tongue and soft palate backwards into that space; on your side, it pulls them sideways where there is room. That's the whole mechanism, and it's why the same person can be silent on their side and thunderous on their back. More detail in sleep position and snoring and how to stop snoring on your back.
The alignment test
Lie in your usual sleeping position and have someone photograph you from the front and from above. Your nose should line up with the middle of your chest, and your neck should form a straight line with your spine — not tilted down towards the mattress, not cranked up towards the ceiling. If your head sags, the pillow is too thin. If your chin is pushed towards your chest, it's too thick or there are two of them.
| Position | Pillow loft | Effect on snoring |
|---|---|---|
| Side, correct loft | 10–14cm firm | Best — airway stays open |
| Side, flat pillow | Under 7cm | Neck bends, partial benefit lost |
| Back, torso raised | Wedge 10–15cm | Helpful compromise |
| Back, flat | 7–10cm | Worst common position |
| Back, two stacked pillows | 18cm+ | Often worse than flat |
Raise the torso, not the head
Elevating the upper body by 10–15cm reduces snoring for many people and also helps anyone whose snoring worsens with acid reflux. The way to do it is to raise the head end of the bed itself — bed risers under the top two legs work — or to use a full-length wedge that starts at the hips. A small triangular cushion that only lifts the skull achieves the opposite of what you want.
Staying on your side all night
Most people can start on their side and few stay there. The reliable methods: hug a full-length body pillow so your top arm and knee are supported, place a second pillow or rolled duvet along your back as a barrier, and if you still roll, use the old tennis-ball-in-a-pocket trick for a fortnight until the habit sets. Shoulder pressure is the usual reason side sleeping fails — a softer mattress topper or a pillow with a shoulder cut-out fixes that.
When the pillow itself is the problem
An old pillow that has lost its loft leaves your neck bent for seven hours a night. Replace fibre pillows every one to two years and foam every two to three. If you want a pillow designed around the airway rather than just around comfort, our anti-snoring pillow guide compares wedge, contoured, side-sleeper and smart positional options with UK prices, and the Nitetronic review covers the one that repositions your head automatically.
If position isn't enough
Give any change a full two weeks before judging it. If you're still snoring on your side, with your neck straight and your torso raised, the obstruction isn't positional — it's most likely nasal or at the tongue base.

Frequently asked questions
What is the best pillow position to stop snoring?
Sleep on your side with a pillow that keeps your head level with your spine — usually 10–14cm of loft for side sleeping — and add a second pillow hugged against your chest to stop you rolling onto your back. Keeping the head and neck in a straight line matters more than raising the head.
Does raising the head of the bed help snoring?
Yes, raising the whole upper body by about 10–15cm helps many people, because it reduces the backward pull of gravity on the tongue and soft palate. Raise the head of the bed or use a wedge — stacking normal pillows bends the neck forward and can make snoring worse.
Should I sleep with one pillow or two?
One correctly sized pillow under the head, plus optionally one between or in front of the knees or chest for positional support. Two pillows stacked under the head usually kink the neck, narrowing the airway rather than opening it.
Is sleeping without a pillow better for snoring?
Only for some back sleepers with a very flat upper back. For most people, no pillow lets the head tip backwards or the chin drop, both of which can worsen snoring. Side sleepers definitely need loft to fill the gap between shoulder and ear.
What pillow height stops snoring?
Side sleepers generally need 10–14cm of firm loft; back sleepers need a lower 7–10cm with some neck support. The test is simple: lying in your usual position, your nose should line up with the centre of your chest and your neck should look straight from the front.
Does a wedge pillow stop snoring?
A wedge that raises the whole torso from the hips upwards helps, especially for people whose snoring is worse with reflux. A small triangular wedge that only lifts the head bends the neck and often achieves nothing.
How do I stop rolling onto my back?
The classic trick is a tennis ball or a rolled towel in a pocket sewn to the back of your nightshirt. A body pillow along your back, or hugging a full-length pillow in front, works just as well and is far more comfortable in the long run.
Will changing pillow position be enough on its own?
For positional snorers — those who only snore on their back — it often is. If you snore in every position, or your partner reports gasping and pauses, position is a helpful addition but the cause is elsewhere and needs assessing.
