Sleeping on your back or your side are the two best positions for neck pain. Both allow your cervical spine to stay in a neutral, relatively straight line overnight, which prevents the sustained muscle strain and joint compression that cause you to wake up stiff and sore. The position itself matters, but so does your pillow, your mattress firmness, and what you do in the minutes before you get into bed.
Back Sleeping Keeps Your Neck Neutral
Lying on your back distributes weight evenly across your spine and lets your neck rest without twisting or bending to one side. The key is pillow choice: you want a rounded pillow that supports the natural inward curve of your neck while keeping your head relatively flat. A pillow that’s too high or too stiff pushes your chin toward your chest, keeping your neck flexed for hours and producing that familiar morning stiffness.
For back sleepers, a low to medium loft pillow with medium firmness works best. If your mattress is soft, go with a lower, softer pillow since your body sinks in more. On a firm mattress, you can go slightly higher and firmer because your head sits further from the surface. Memory foam contour pillows with a built-in neck ridge and a shallow dip for the back of your head are a popular option, since they cradle without pushing your head forward.
Side Sleeping Works With the Right Pillow Height
Side sleeping is equally good for your neck, provided you fill the gap between your shoulder and the side of your head. Without enough pillow height, your head droops toward the mattress all night, stretching the muscles and compressing the joints on one side of your neck. Too much height does the reverse, crimping the opposite side.
Side sleepers generally need a higher loft pillow, roughly 5 to 7 inches, with medium-firm to firm support. The firmer your mattress, the higher and firmer your pillow should be, because your shoulder doesn’t sink in as much and the gap between your head and the bed is larger. On a soft mattress, you can drop to a medium loft and medium firmness since your shoulder compresses into the surface.
A simple way to check: lie on your bed in your normal position and have someone look at you from behind. Your head, neck, and spine should form a straight horizontal line. If your head tilts up or down, your pillow height is wrong.
Why Stomach Sleeping Causes Problems
Sleeping on your stomach is the hardest position on your neck. Your head has to turn fully to one side so you can breathe, which keeps your cervical spine rotated for hours. At the same time, lying face-down arches your lower back and compresses the front of your neck. Research on prone positioning shows it can worsen narrowing of the spinal canal and reduce blood flow to the spinal cord compared to lying on your back.
If you can’t break the habit, use a very thin, soft pillow or no pillow at all to minimize how far your neck bends upward. But transitioning to side sleeping, even partially, will make a noticeable difference for most people with recurring neck pain.
A DIY Neck Roll for Extra Support
You don’t need to buy a specialty pillow to improve your neck support tonight. A simple rolled towel can fill the gap for back sleepers. Fold a hand towel in half lengthwise, roll it into a cylinder, and optionally tape the end so it holds its shape. Slide the roll into the bottom edge of your pillowcase so it sits snugly against the lower curve of your neck when you lie down. The rolled towel supports your cervical curve while the flat part of the pillow cradles the back of your head. It’s a technique physical therapists commonly recommend and costs nothing to try.
Choosing the Right Pillow Material
The three most common materials each behave differently. Memory foam uses your body heat and weight to slowly mold to the contours of your head and neck. It provides consistent, even support, and higher-density versions can hold their shape for up to three years. The downside is that solid memory foam blocks airflow and sleeps warm.
Shredded memory foam fills are more adjustable. Many of these pillows let you add or remove filling to dial in the exact loft and firmness you need, which makes them a good choice if you switch positions at night. Latex offers a bouncier, more responsive feel. Instead of slowly sinking in, it provides immediate pushback that keeps your head from settling too deep. It also sleeps cooler than memory foam.
Feather pillows conform easily to your neck’s shape and feel comfortable, but they collapse relatively quickly and typically need replacing every year. For someone actively managing neck pain, a pillow that maintains consistent loft night after night is more reliable than one that slowly goes flat.
What About Your Mattress?
Mattress firmness affects neck pain indirectly by changing how far your shoulders and torso sink, which in turn changes the angle of your neck. A mattress that’s too soft lets your body sag, pulling your spine out of alignment. One that’s too firm creates pressure points at the shoulder (for side sleepers) that force the neck into awkward angles. Medium-firm is the most commonly recommended range for spinal alignment, though no clinical studies have directly tested mattress interventions for chronic neck pain specifically. The practical takeaway: your mattress and pillow work as a system. If you change one, you may need to adjust the other.
Stretches to Do Before Bed
Loosening your neck and upper back muscles before sleep can reduce the baseline tension you carry into the night. These four stretches, recommended by the Hospital for Special Surgery, take about five minutes total.
- Lateral neck stretch: Sit or stand tall. Tip your right ear toward your right shoulder while reaching your left hand toward the floor. Use your right hand to gently guide the stretch. Hold 20 to 30 seconds, repeat two to three times, then switch sides.
- Neck twist: Place your right hand behind your back, palm facing out. Tilt your head to the left and turn it down toward your left hip. Gently guide with your left hand while reaching your right hand downward. Hold 20 to 30 seconds, two to three times per side.
- Lying T-twist: Lie on your right side with knees bent and arms stacked. Slide your top arm across your body, rotating your upper back and head to the left until your arms form a T shape. Hold 10 seconds, return, and repeat three to five times before switching sides.
- Doorframe chest stretch: Stand in a doorway with your forearms flat on the frame, elbows at shoulder height. Lean forward until you feel a stretch across your chest and the front of your shoulders. Hold 30 seconds, repeat two to three times.
The chest stretch might seem unrelated to your neck, but tight chest and front-shoulder muscles pull your posture forward during the day, which loads the back of your neck. Releasing that tension before bed helps your neck settle into a more neutral position on the pillow.
Putting It All Together
Sleep on your back or side. Match your pillow height and firmness to your position and mattress: lower and softer for back sleepers, higher and firmer for side sleepers. If you’re on a budget, start with the towel roll trick tonight and see if your mornings improve. Avoid stomach sleeping when possible, stretch your neck and chest before bed, and check your alignment with the straight-line test. Small adjustments to your sleep setup often produce results within the first week.
