Lower back pain and poor sleep feed each other: the pain makes it hard to get comfortable, and a bad night lowers your pain threshold so the back hurts more the next day. (How poor sleep makes everything hurt more.) The lever you control overnight is spinal alignment — keeping the spine in a neutral position instead of a strained one — and a few simple adjustments can make a real difference. (This is general information, not medical advice.)
The best positions for a sore lower back
The goal is to keep the natural curve of the spine supported and avoid twisting or over-arching it:
- On your back with a pillow under your knees. This is often the most back-friendly position — it keeps the spine neutral and takes pressure off the lower back. A small rolled towel under the lower back can add support.
- On your side with a pillow between your knees. Keeps the hips, pelvis, and spine aligned rather than letting the top leg rotate the lower back. Draw the knees up slightly.
- If side-sleeping, alternate sides to avoid muscle imbalance.
The position to avoid
Stomach sleeping is the hardest on a bad back — it flattens the natural curve and forces the lower spine into extension, while the turned head strains the neck. If you cannot break the habit, put a thin pillow under your pelvis to reduce the arch, and read the position-change tips below. (Is it bad to sleep on your stomach?)
Mattress, pillow, and getting in and out
- Mattress: a medium-firm surface suits most people with back pain — enough support to keep the spine aligned, enough give to cushion the hips and shoulders.
- Pillow: keep your head and neck neutral, neither propped too high nor flat.
- Log-roll in and out of bed: move as a single unit, rolling to your side and pushing up with your arms rather than twisting up from flat, which spikes back pain.
When to see a doctor
Most positional back pain eases with better support, but red flags need prompt medical attention: leg weakness or numbness, pain shooting down a leg (possible sciatica), or any loss of bladder or bowel control, which is an emergency. (How to sleep with sciatica.)
One note if back-sleeping becomes your new default: lying on your back is great for the spine but can make snoring worse by letting the airway narrow. If you notice that trade-off, it is worth understanding the breathing side too. (The best sleep position for snoring.)

FAQ
What is the best sleeping position for lower back pain? For most people, lying on your back with a pillow under the knees is the most back-friendly, because it keeps the spine neutral and takes pressure off the lower back. Side-sleeping with a pillow between the knees is a good alternative that keeps the hips and spine aligned. Stomach sleeping is the hardest on a sore back.
Why is stomach sleeping bad for back pain? Stomach sleeping flattens the natural curve of the lower spine and forces it into extension, while the turned head strains the neck. Both aggravate back pain. If you cannot avoid it, a thin pillow under the pelvis reduces the arch, but transitioning to back or side sleeping is better for a sore back.
What mattress is best for lower back pain? A medium-firm mattress suits most people with back pain — firm enough to keep the spine aligned but with enough give to cushion the hips and shoulders. The right choice is partly individual, so comfort and waking pain levels are the real test, but very soft or very hard surfaces tend to work less well.
When should I see a doctor about back pain and sleep? See a doctor promptly for red flags: leg weakness or numbness, pain shooting down a leg, or any loss of bladder or bowel control, which is a medical emergency. Ordinary positional back pain that eases with better support is less urgent, but persistent or worsening pain also warrants evaluation.
The bottom line
The overnight fix for lower back pain is spinal alignment: sleep on your back with a pillow under your knees, or on your side with a pillow between them, on a medium-firm mattress, and avoid stomach sleeping. Log-roll in and out of bed to protect the back. And if back-sleeping leaves you snoring more, address the breathing side rather than giving up the position that helps your spine.
