Best Position to Sleep for Lower Back Pain

The best position to sleep for lower back pain is the one where your back wakes up quietest, and for many people that means lying on one side or on the back with a pillow for support. Nobody has shown that one position suits everyone. So this page gives you the options, and lets your own mornings be the judge. Awareness of how your body feels is also the heart of the Feldenkrais Method®, and it is the most useful tool you have here.

Lower back pain is very common. It affects about 619 million people worldwide, and in about 90% of cases there is no single specific cause that can be found (WHO, 2023). That is one reason sleeping advice stays loose: if the cause differs from person to person, the best position will too.

The positions side by side

Here is how the usual choices compare. None of this is a rule. It is a starting point for a small experiment.

Position	What to add	Why many backs like it	Watch for
On your side	Pillow between the knees	The top leg stays level, so the pelvis is not pulled round	A gap at the waist, or a top knee that drops forward
On your back	Pillow under the knees	Bent hips let the lower back rest closer to flat	A flat back can feel stiff if you like a little curve
On your stomach	Slim pillow under the hips	Takes some of the arch out of the lower back	The neck turns and the back can arch again
Curled up like a ball	Pillow between the knees	Feels safe and gentle for some people	A very tight curl can leave you stiff on waking

You can see why the first two come up so often. They ask the least of your back. If you are curious about the stomach option, our guide on how to sleep on your stomach without back pain goes through it step by step.

Why comfort is the guide, not a rule

Trials comparing sleeping positions for back pain are small and few. So when someone tells you there is one best way to lie, they are claiming more than the research can back up. What we do know is that lying still in a strained shape for hours can leave a back sore, and that a position that feels easy at bedtime does not always feel easy at 7 a.m.

That is why the test happens in the morning. Your back at bedtime is tired and often distracted. Your back at waking tells you what the night was like for it. Our Feldypedia note on waking with stiffness and pain explains why those first minutes say so much.

How to try it

Change one thing for a few nights. Only one. If you usually sleep on your side, add a pillow between your knees. If you lie on your back, slide a pillow under your knees. Then, each morning, take a moment before you get up and ask: how does my lower back feel right now? Stiff, easy, somewhere between? A word or two in a notebook is enough.

If you also carry tension into bed, a short, slow lesson done lying down can help your back settle first. Our somatic exercises for sleep are a gentle place to start. For the broader picture, see our guide on how to prevent lower back pain when sleeping.

Getting in and out of bed gently

Twisting up from flat is a common moment for a sharp twinge. Move in one piece instead, with what is often called a log roll.

To get out of bed:

1. Bend both knees, with your feet flat on the mattress.
2. Roll onto your side, turning your shoulders and hips together like a log.
3. Lower your legs over the edge of the bed while you push up with your arms.
4. Sit for a moment before you stand.

To get in, do the same steps in reverse. It feels slow for the first few days, and then it feels normal.

When to see a doctor

A better sleeping position is a comfort measure, not a treatment. See a doctor if your back pain is severe or getting worse, wakes you whatever position you try, or hurts more at rest than when you move. Go promptly if it comes with a fever, unexplained weight loss, a leg that feels numb or weak, any bladder or bowel changes, or began after a fall.

Find where to start

Sleep position is only one part of a quiet back. The way you move by day matters too, and the right gentle approach differs from person to person.

Common Questions about the best position to sleep for lower back pain (FAQ)

What is the best position to sleep in with lower back pain?

Most people with a sore lower back find one of two positions easiest. One is on the side with a pillow between the knees. The other is on the back with a pillow under the knees. Neither is proven best for everyone, so choose the one where you wake with the least stiffness.

What sleeping position should I avoid with lower back pain?

Lying flat on your stomach with no support is the one most people find hardest, because it can pull the lower back into an arch and turn the neck. You do not have to give it up. A slim pillow under the hips often eases it. Any position you wake from in more pain is worth changing.

Is it safe to try a new sleeping position when my back hurts?

For ordinary aches, yes. These changes add pillows, not effort. Stop and change back if a position makes the pain sharper, sends pain or tingling down a leg, or wakes you. If pain comes with a fever, a weak or numb leg, or bladder or bowel changes, see a doctor promptly.

How long should I try a new sleeping position before deciding?

Give it three to five nights. The first night often feels odd simply because it is new. Judge it by how your back feels when you wake up, not by how it feels as you lie down. If one change is not helping after that, try another one, and change only one thing at a time.

How long until a new sleeping position eases my back?

Some people notice a softer morning within a few nights. For others it takes a couple of weeks, and some feel little change. Sleep position is one piece among many, including how tense you are at bedtime and how you move during the day. If your pain is not easing after a few weeks, ask a professional.

Is changing position better than buying a new mattress for lower back pain?

They do different jobs. A position change costs nothing and you can test it tonight. A mattress is a bigger decision, and the evidence on it is mixed. Try the position and pillow changes first, and keep the mattress question for later if your back still wakes you stiff.

When should I see a professional about back pain at night?

See a doctor if the pain wakes you whatever position you try, keeps getting worse, or is worse at rest than when you move. Go promptly if it comes with a fever, weight loss you cannot explain, weakness or numbness in a leg, bladder or bowel changes, or follows a fall.
