Sleeping Positions for Back Pain: What Helps and How
For most people with back pain, the most comfortable positions are lying on your side with a pillow between your knees, or lying on your back with a pillow under your knees. Both keep your spine, pelvis and hips in a more neutral line. Sleeping on your front is usually the hardest on your back. Below we explain how to set each position up, how to deal with hip and neck pain at night, and when night pain needs a clinical assessment.
TL;DR
Side sleeping with a pillow between your knees, or back sleeping with a pillow under your knees, are the two positions most commonly advised for back pain.
Your head pillow should keep your neck level with the rest of your spine. For neck pain, the NHS advises a low, firm pillow.
Back pain that is worse at night, or has not improved after a few weeks of self-care, is a reason to see a GP or physiotherapist.
A changed sleeping position is one part of managing pain. Staying active and a proper assessment of the cause matter just as much.
At Parks Therapy Centre, a physiotherapy assessment is £76, and we can look at your sleeping set-up as part of your plan.

Why sleeping position affects back pain
You spend around a third of your life in bed, so the position you hold affects how your back is loaded for hours at a time. A position that twists the pelvis, arches the lower back or pulls the neck to one side can keep muscles and joints irritated overnight. You then wake up stiff, even if the day before felt fine.
The aim is simple: support the natural curves of the spine and avoid holding any joint at the end of its range. Mayo Clinic explains that flexing the knees and placing a pillow between the legs helps align the spine, pelvis and hips when you sleep on your side. That principle applies to every position below.
It also helps to be realistic. Sleeping position rarely causes back pain on its own. The NHS lists injury such as a pulled muscle, and conditions such as a slipped disc, sciatica or ankylosing spondylitis among the common causes. Position changes make you more comfortable while the underlying problem is treated.
The best sleeping positions for back pain
On your side, with a pillow between your knees
This is the position most people find easiest to hold. When you lie on your side, the top leg tends to fall forward and twist your pelvis, which pulls on your lower back. A pillow between the knees stops that.
The NHS Sussex Community advice is to try a small pillow between your knees if you sleep on your side.
How to set it up:
Lie on your side with your hips and shoulders stacked, not rolled forward or back.
Bend your knees slightly. You do not need to curl into a tight ball.
Place a pillow between your knees and, if you can, between your ankles too, so the whole top leg is supported.
Use a head pillow that fills the gap between your ear and the mattress, so your neck stays level.
If there is a gap at your waist, a small rolled towel can fill it.
A full-length body pillow does the same job if you prefer one. Switch sides during the night if you wish, as long as the pillow comes with you.
On your back, with a pillow under your knees
Lying on your back spreads your weight over the largest area. Mayo Clinic suggests a pillow under your knees to help relax the back muscles and maintain the curve of the lower back, with a small rolled towel under the waist if you need extra support. The NHS Sussex Community guidance also mentions a small pillow under the knees for people who lie on their back.
Keep the pillow modest in size. The knees should be gently bent, not pulled up high. Your head pillow should not push your chin towards your chest.
On your front
Mayo Clinic notes that sleeping on your stomach can be hard on your back. It tends to arch the lower back and turn the neck to one side for hours. The NHS also advises not sleeping on your front to prevent neck pain, as set out on its neck pain page.
If you cannot sleep any other way, reduce the strain by putting a thin pillow under your hips and lower stomach, and use a flat pillow under your head, or none, if it does not strain your back. Then try, over a few weeks, to shift towards your side.
Reclined or slightly raised
Some people with acute pain find a flat bed impossible and are more comfortable with the upper body raised a little on pillows or an adjustable base. This can be a short-term answer during a flare-up. The aim is still support under the knees and a neutral neck.
Quick comparison
Position | Support to add | Works well for | Watch for |
Side, knees bent | Pillow between knees (and ankles), head pillow filling the neck gap | Most mechanical lower back pain, pregnancy discomfort, sciatic-type aching | Top leg dropping forward and twisting the pelvis |
Back | Small pillow under knees, rolled towel under waist if needed | Stiffness that eases when the back is supported | Pillow too thick, which pushes the head forward |
Front | Thin pillow under hips and lower stomach, flat head pillow | Only if no other position is possible | Arched lower back and a twisted neck |
Slightly raised | Pillows or adjustable base, plus knee support | Short flare-ups | Slumping down the bed in the night |
Does the mattress matter?
A mattress that sags lets the hips sink and bends the spine, while one that is too hard can leave pressure points at the shoulder and hip when you lie on your side. The NHS neck pain advice recommends a firm mattress alongside keeping the head at the same height as the rest of the body. Firmness is personal, though. If you are weighing materials, a guide to memory foam mattresses and back pain covers how firmness and support interact.
Before you spend money, try the simple changes first: a pillow between the knees, a head pillow of the right height, and a mattress that is not visibly sagging.
Waking with hip pain or pain on one side
Side sleeping is helpful for the back but it can load the hip you lie on. The NHS lists bursitis, where pain may spread to the upper leg and feel worse when lying on your side, osteoarthritis, and rheumatoid arthritis among the common causes of hip pain. If your back and hip ache after sleeping, try these steps:
Put the pillow between the knees and ankles, so the top hip is not pulled inwards.
Try lying on the other side, or on your back with knee support, on alternate nights.
Add a thicker, softer layer such as a mattress topper if the hip is pressing hard into the mattress.
Move gently for a few minutes in the morning rather than staying curled up.
If you want more on hip pain that is worse on the affected side, our guide to hip bursitis treatment explains how we approach it.
Neck pain and tension headaches at night
Back pain, neck stiffness and tension headaches often arrive together, and the pillow is a common link. For neck pain the NHS recommends a low, firm pillow and heat or cold packs. Its tension headache advice is similar for people who have neck pain with their headaches, and adds that if sleep problems may be causing the headaches, changing your sleeping habits is worth trying.
Can massage help a tension headache?
The NHS suggests relaxing activities such as exercise, yoga and massage to ease tension headaches. A 2024 systematic review found that trigger point therapy techniques, including ischaemic compression and massage focused on trigger points, reduced the duration, intensity and frequency of tension-type headaches. The same review explains that trigger points in the neck and shoulders can refer pain to the head.
For a gentle self-massage at home:
Sit with your shoulders relaxed and your neck supported.
Use your fingertips to apply light, steady pressure to the muscles either side of the spine at the base of the skull.
Hold for 20 to 30 seconds, then release, and move down towards the top of the shoulder.
Stop if it increases the pain, tingling or dizziness.
If tight neck and shoulder muscles keep returning, a physiotherapist or sports massage therapist can find the tender areas and treat them directly. Our sports massage is priced at £60 per hour.
Headaches that need urgent attention
Do not treat these with massage. The NHS says to get an urgent GP appointment or call 111 for a severe headache with jaw pain when eating, blurred or double vision, a sore scalp, or numbness or weakness in the arms or legs.
Other things that help at night
Position is only one part of a good night. These habits support it:
Stay active in the day. The NHS advises staying active, using ice or heat packs and not staying in bed for long periods when you have back pain.
Use heat before bed. A warm bath or a heat pack on the lower back for a short time can ease stiffness before you lie down.
Check your medicines. The NHS says anti-inflammatory medicines like ibuprofen may help, and that paracetamol on its own is not recommended, as set out on its back pain page. Ask a pharmacist if you are unsure what suits you.
Get in and out of bed carefully. Roll onto your side, drop your legs over the edge and push up with your arms, rather than sitting straight up from lying.
Keep a routine. A regular bedtime and a calm, dark room make it easier to settle when you are sore.
Our guides to lower back pain exercises and pain management strategies cover what to do between nights, and Pilates for back care shows exercises that build the trunk support your back relies on.
When night pain needs more than a pillow
A better position should make you more comfortable within a few nights. If it does not, the problem may not be positional. The NHS advises seeing a GP for back pain if it does not improve after treating it at home for a few weeks, is stopping you doing day-to-day activities, is worse at night, or comes from the top of your back rather than your lower back.
For a slipped disc, the NHS lists a very high temperature, unexplained weight loss, swelling in the back, or pain that is worse at night as reasons to see a GP, as well as painkillers not helping. A slipped disc can also cause numbness or tingling, muscle weakness, and pain in the buttocks, hips or legs if it presses on the sciatic nerve. For hip pain, the NHS advises seeing a GP if it is affecting your sleep, getting worse, or has not improved after 2 weeks of home treatment.
The NHS also says that very rarely, back pain can be a sign of a serious problem such as a broken bone, cancer or infection. That is why pain that wakes you, keeps worsening or comes with other symptoms deserves a proper assessment rather than more pillows.
What a physiotherapist looks at
A physiotherapy assessment looks beyond the bed. We ask when the pain starts, which movements and positions ease it, how you sit and work, and what you have already tried. We then examine your spine, hips and nerves, explain what we think is happening, and agree a plan. That plan might combine hands-on treatment, exercises, advice on sleeping positions and a return to the activities you enjoy.
If your symptoms suggest that scans would help, we can arrange an image referral, and our price list includes an image assessment, referral letter and results review.
We have treated people with back pain in Bedfordshire and Buckinghamshire since 1986, and sleep comes up in almost every conversation. People tell us they have tried several positions, bought a new pillow and still wake up sore. Our view is that sleeping position works best as part of a wider plan. Support at night helps you rest, but lasting improvement usually comes from understanding why your back is irritated, then treating it and strengthening it. That is the value of seeing a multidisciplinary team: physiotherapy, sports massage, acupuncture, Pilates and shockwave therapy are all available under one roof, so the plan can fit the person rather than the other way round. We would rather you came in for a clear explanation after a few weeks of broken nights than carried on guessing. A good assessment gives you a position, a pillow set-up and exercises that suit your body. Ivan

FAQ
What is the best sleeping position for lower back pain?
Most people do best lying on their side with the knees slightly bent and a pillow between them. Lying on your back with a small pillow under your knees is a good alternative. Choose the one you can hold comfortably, and support your neck in both.
Does a pillow between the knees really help?
Yes, for many people. It stops the top leg dropping forward and twisting the pelvis, which keeps the spine, pelvis and hips better aligned. The NHS Sussex Community advises trying a small pillow between the knees when sleeping on your side. If it does not help within a week or so, have your back assessed.
Is it bad to sleep on my stomach with back pain?
It is often harder on the back and neck, because it arches the lower back and turns the head. If you cannot sleep any other way, place a thin pillow under your hips and lower stomach. Gradually practise side sleeping with a pillow between the knees.
Why does my back hurt more in the morning?
Pain on waking can come from an unsupportive position, a sagging mattress, or a cause such as a strained muscle, arthritis or a disc problem. Stiffness that lasts a long time, or pain that is worse at night, should be checked by a GP or physiotherapist.
Can massage help with tension headaches that come with a stiff neck?
It may help. The NHS lists massage among relaxing activities to ease tension headaches, and research on trigger point therapy has found reduced headache frequency and intensity. Seek urgent medical help if a headache is severe or comes with vision changes, jaw pain when eating or numbness.
