Best Sleeping Positions for Back Pain

By Nova Physical Therapy, an outpatient physical therapy clinic in North Hollywood, CA | Published October 2026

You go to bed feeling fine and wake up stiff and sore. It takes a hot shower and a slow walk to the kitchen before your back loosens up. Or maybe your back pain keeps waking you up at night, and you can't find a position that feels right.

Many people with back pain wonder if they're sleeping "wrong." This article explains what research says about sleeping positions, simple pillow setups that many people find more comfortable, what to know about mattresses, why morning stiffness happens, and which signs mean you should get checked.

The short answer

There's no single "best" sleeping position for everyone with back pain, and research on sleep posture is limited. A review of the available studies found that side lying was most often linked with fewer waking spinal symptoms, but the authors concluded there weren't enough high-quality studies to give firm answers (Cary et al., 2019). For mattresses, a randomized trial found that people with chronic low back pain improved more often on a medium-firm mattress than on a firm one (Kovacs et al., 2003). The most practical approach is to use pillows to keep your spine in a comfortable, neutral position, and to stay active during the day. Back pain that wakes you up every night or comes with other warning signs should be checked. In California, you can see a physical therapist without a referral.

What is the best sleeping position for back pain?

The best position is usually the one that lets you sleep comfortably and wake up with less pain. Here are setups many people find helpful:

• On your side: bend your knees slightly and place a pillow between them. This keeps your top leg from pulling your pelvis and lower back into a twist. A pillow that fills the space between your ear and shoulder helps your neck too.
• On your back: place a pillow under your knees. Many people find this takes pressure off the lower back.
• On your stomach: if this is the only way you can sleep, a thin pillow under your hips and a flat pillow (or none) under your head may make it more comfortable.

Research doesn't clearly show that one of these is better than the others for everyone. In the available studies, side lying was most often linked with fewer symptoms, while some studies linked stomach sleeping and certain twisted positions with more symptoms (Cary et al., 2019). Try a setup for a week or two and see how you wake up.

Why does my back hurt more in the morning?

Morning stiffness is common with back pain. Some likely reasons:

• Staying still for hours. Joints and muscles often feel stiff after long periods without moving.
• A position that strains your back. Twisting, or lying flat on your stomach with your back arched, may bother some people.
• A mattress that doesn't suit you. One that's too soft or too hard may leave you sore.
• Less activity during the day. People who move less often feel stiffer.

Stiffness that eases within about 30 minutes of getting up and moving is common with mechanical back pain. Morning stiffness that lasts much longer, especially in younger adults, is worth mentioning to your physician, because it can point to inflammatory conditions that need medical evaluation.

Does my mattress matter?

It can. In a trial of 313 adults with chronic low back pain, those given a medium-firm mattress were more likely to report less pain in bed and less disability after 90 days than those given a firm mattress (Kovacs et al., 2003). The trial only tested spring mattresses, so it can't tell you which brand or type is best.

Practical tips:

• "Firmer is better" isn't necessarily true; medium-firm worked better in that trial
• Comfort matters, so try a mattress for a few weeks if the store allows it
• If your mattress sags in the middle, that may be worth addressing
• A new mattress alone rarely fixes back pain; daytime activity matters too

What can I do before bed and after waking up?

Small habits can make nights and mornings easier:

• Stay active during the day. The APTA low back pain guideline supports exercise and staying active for most people with back pain (George et al., 2021).
• Do a few gentle movements before bed, like knee-to-chest or gentle back rotations, if they feel good.
• Get out of bed with a "log roll": roll onto your side, drop your legs over the edge, and push up with your arms.
• Move early in the morning. A short walk or a few gentle stretches often ease stiffness faster than staying still.
• Keep a regular sleep schedule. Poor sleep and pain often feed each other.

How can physical therapy help?

A physical therapy evaluation may include:

• Your symptoms, sleep habits, and what makes pain better or worse
• Back and hip motion, strength, and movement testing
• Which positions ease or bother your back
• Screening for signs that need a physician's evaluation

A typical plan may include:

• A sleep position and pillow setup based on what we find
• Gentle morning and evening movement routines
• Exercise to build strength and tolerance in your back and hips
• Hands-on treatment when it helps you move better
• A home program you can keep doing on your own

Physical therapy doesn't guarantee a specific result or timeline. Questions about sleep medication or sleep disorders are best directed to your physician.

At Nova Physical Therapy in North Hollywood, back pain care is one of our core services, and every plan starts with an evaluation so treatment fits what we find.

When should I see a doctor?

See a physician promptly if you have:

• Back pain that wakes you up every night and doesn't ease with changing position
• Pain at rest that keeps getting worse
• Morning stiffness that lasts more than about an hour, especially if you're under 45
• Fever, unexplained weight loss, or a history of cancer
• Back pain after a fall or injury, especially if you have osteoporosis
• Numbness, tingling, or weakness in your legs
• Loud snoring or pauses in breathing during sleep, which a physician should evaluate

Get emergency care for loss of bladder or bowel control, numbness in the groin or inner thighs, or sudden weakness in both legs.

We screen for these signs during every evaluation and refer you to a physician when findings call for medical assessment.

Do I need a referral for physical therapy in California?

Not to get started. California allows direct access to physical therapy. A physical therapist can evaluate and treat you without a referral for up to 45 calendar days or 12 visits, whichever comes first. After that, a physician or podiatrist needs to sign the plan of care for treatment to continue. Your insurance plan may have its own referral rules, so check your coverage.

Frequently asked questions

What is the best sleeping position for lower back pain?
There's no single best position for everyone. Many people find side lying with a pillow between the knees, or lying on their back with a pillow under the knees, more comfortable.

Is sleeping on your stomach bad for your back?
It bothers some people because it can arch the lower back and twist the neck. If it's the only way you can sleep, a thin pillow under your hips may help.

Should I sleep with a pillow between my knees?
Many side sleepers find it helps by keeping the pelvis and lower back from twisting. It's simple and worth trying.

Is a firm mattress better for back pain?
Not necessarily. In one trial, people with chronic low back pain improved more often on a medium-firm mattress than on a firm one.

Why does my back hurt after sleeping but feel better during the day?
Staying still for hours often leads to stiffness that eases with movement. Sleep position and mattress may also play a role. Long-lasting morning stiffness should be checked by a physician.

Can physical therapy help with back pain at night?
Yes, for many people. A physical therapist can suggest positions, pillow setups, and exercises, and screen for signs that need a physician's evaluation.

Do I need a referral to see a physical therapist?
No, not to start. California allows direct access within the limits described above.
