Sleeping position and pillow for neck pain

Wake up with a stiff neck a few times and you start looking for a better pillow for neck pain. The shelves are full of contour, memory foam, latex and “orthopaedic” options, and the claims on the packaging run well ahead of the research. This page sets out what the studies have actually tested, what the NHS advises, and where the honest answer is that nobody knows yet.

What the NHS advises

The NHS neck pain page lists a few sleep-related points (NHS):

• use “a low, firm pillow”
• “when sleeping, make sure your head is the same height as the rest of your body”
• “have a firm mattress”
• “do not sleep on your front”
• “do not twist your neck when you’re in bed”

It also names “the neck becoming locked in an awkward position while sleeping” as one of the most common causes of neck pain. The page doesn’t say what evidence each point rests on, and as the rest of this page shows, the research only partly lines up with it. The core idea, keeping your head roughly in line with your body, is the thread that runs through most of the studies.

Is there a best pillow for neck pain?

Not one that has been proven. But some types have done better than others in head-to-head trials.

The best overview. A 2021 systematic review found 35 studies of pillows, of which nine, with 555 participants, were judged high quality. In people with long-term neck pain, rubber (latex) pillows reduced neck pain more than the comparison pillows, though the effect was small. Waking pain and neck disability improved too, and people were more satisfied with their pillows. Pillow design made no difference to sleep quality. The review also found that the shape and height of a pillow affected the alignment of the cervical spine more than whether it was filled with rubber or feathers (Chun-Yiu et al., 2021).

The largest home trial. An Australian group asked 106 side sleepers to spend a week on each of five pillows, plus their own: polyester, foam, feather, latex and a contoured foam pillow. The latex pillow did better than people’s own pillows in most comparisons. Foam and polyester performed about the same as people’s own. The contoured foam pillow showed no advantage over the regular foam one, and the authors concluded that feather pillows “should not be recommended” (Gordon et al., 2009). A second report from the same trial, looking at morning stiffness, headache and shoulder blade pain, found the same order: latex best, feather worst, and contour no better than regular foam (Gordon et al., 2010).

Your current pillow isn’t automatically fine. In that trial, only 42.5% of people reported no waking symptoms on their own pillow, and over half reported regular waking symptoms, an uncomfortable pillow or poor sleep. Poor sleep quality was linked to waking neck stiffness (Gordon & Grimmer-Somers, 2011).

But a pillow can’t fix everything. In a small pilot trial of people with known wear-and-tear changes in the neck, who tried latex and polyester pillows for 28 days each, no pillow made a significant difference to any outcome (Gordon et al., 2019).

Put together: latex has the most support, contour shapes haven’t beaten ordinary pillows, and feather did worst. The home trials described here all come from one research group and mostly tested side sleepers, so the picture is narrower than the marketing suggests. Memory foam wasn’t tested separately in the studies checked for this page.

How high should your pillow be?

This is where the evidence is weakest. A 2021 review of pillow height research concluded that there are still “no firm conclusions about the optimal pillow height” for lying on your back or side (Lei et al., 2021).

What small lab studies suggest is that the right height depends on your build. In 15 young adults lying on their side, pillow heights scaled to each person’s shoulder width changed how hard the sternocleidomastoid and trapezius worked; the middle height gave the lowest muscle activity and was rated most comfortable (Jiao et al., 2024). In nine people, a medium pillow height matched to shoulder width, with neck support, kept the neck’s natural curve, its cervical lordosis, closest to how it looks when standing (Tian et al., 2025).

That fits the NHS’s head-level advice. In practice:

• On your side, the pillow fills the space between your ear and the mattress so your head isn’t tipped up or down. Broad shoulders usually need more height.
• On your back, there is no shoulder to fill the gap, so a pillow that suits you on your side may push your chin towards your chest.
• If you switch a lot, a medium height, or a pillow you can shape, is a reasonable compromise.

Give any pillow time. A lab study of 24 young women found that 71% of their necks had settled on a pillow within 15 minutes of lying on their side, with wide variation (Hodkinson et al., 2013). So a few seconds on a pillow in a shop tells you little about how it will feel at 3am.

Which sleeping position is best for neck pain?

First, a reality check. When 664 Danish workers wore movement sensors in bed, they spent about 54% of the time on their side, 38% on their back and 7% on their front, and changed position about 1.6 times an hour on average (Skarpsno et al., 2017). You won’t hold one position all night, however hard you try.

What the research says about position:

• Side lying looks reasonable. A 2019 scoping review found only four relevant studies, but in them lying on your side was generally protective against spinal symptoms. The authors said there were not enough high-quality studies to answer the question properly (Cary et al., 2019).
• Front and twisted positions go with morning neck pain. In a study of 53 adults filmed at home over two nights, the 13 who woke with neck pain or stiffness spent about twice as long as people without symptoms lying on their side with the top leg rolled forward so the spine twists. They also spent more time overall in that position or on their front, and changed position more often. The authors note an earlier survey in which front sleepers reported the most waking neck symptoms. Because the study looked at one point in time, it can’t say whether the positions caused the pain or the pain changed how people slept (Cary et al., 2021).
• Support changes the picture. In the same study, people whose top leg was propped on a pillow or the duvet weren’t twisting their spine, so the researchers counted that as a supported position (Cary et al., 2021).

So: back and side both seem fine, and front sleeping is the one position the NHS and the small studies both point away from (NHS). If you can only fall asleep on your front, a very low pillow, or none, at least avoids tipping your head back as well as turning it.

Does your mattress matter?

The NHS suggests a firm mattress for neck pain (NHS). The best-known mattress trial was in the lower back, not the neck: 313 adults with long-term low back pain were randomly given firm or medium-firm mattresses, and after 90 days the medium-firm group had less pain in bed and on rising, and less disability (Kovacs et al., 2003). No similar trial for neck pain was found for this page. So “firmer is better” isn’t proven, for the neck or the back.

How to choose a pillow without wasting money

• Start with height, not filling. Lie on your side and check whether your head is roughly level with the rest of your body, as the NHS suggests. If your head tips down or up, the height is wrong.
• If you want to try a different material, latex has the most support and feather the least (Chun-Yiu et al., 2021; Gordon et al., 2009).
• Don’t pay extra for a contour shape unless it simply feels better to you (Gordon et al., 2009).
• Try it for a week or more. That is how long participants slept on each pillow in the trials, and a returns policy makes it less of a gamble.
• Look at your day as well as your night. The NHS lists long spells sitting at a desk as another common cause of neck pain, alongside awkward sleeping positions. The guides to setting up your monitor and microbreaks cover that side.

When a stiff neck in the morning needs checking

The NHS says most neck pain only lasts a few weeks. It advises seeing a GP if (NHS):

• neck pain or stiffness does not go away after a few weeks
• painkillers like paracetamol or ibuprofen have not worked
• you’re worried about the pain
• you have other symptoms, like pins and needles or a cold arm

In many areas you can also get NHS physiotherapy without a GP referral (NHS). For a fuller list of warning signs, see stiff neck after sleeping and neck pain from desk work. If you’re weighing up private treatment, how much physiotherapy costs sets out the options.

A pillow is one part of the picture. Bavelu’s neck sessions are designed and filmed by physiotherapists and can be done on a chair or a mat, with a short version for busy mornings.
