Why side sleeping strains the neck
Side sleeping is one of the two positions the Sleep Foundation calls best for neck pain, along with back sleeping. The catch is the gap. When you lie on your side, your shoulder lifts your head well above the mattress. If the pillow is too low, your head tips down toward the bed. If it is too high, your head bends up toward the ceiling. Either way, the neck spends hours bent sideways.
Cleveland Clinic puts the goal simply: the pillow should keep your neck parallel to the mattress, not bent down or up. The most common mistake it describes is a pillow that bends the neck forward or to one side.
How to choose pillow height for side sleeping
Height (loft) matters more than the label on the bag. Three things set the height you need:
- Shoulder width. Broader shoulders leave a bigger gap. Tempur-Pedic sizes its contour neck pillow by measuring from the base of the neck to the outer edge of the shoulder, and suggests choosing the smaller size if you fall between two. That method works for judging any side-sleeper pillow.
- Mattress feel. Cleveland Clinic advises a thicker pillow on a firm mattress and a thinner one on a memory foam topper or pillow-top, because your shoulder sinks deeper into a soft bed.
- Not too tall. The Sleep Foundation notes side sleepers may want to avoid pillows or stacks that are too thick, since too much height bends the neck the other way.
A quick check from the Sleep Foundation: have someone take a photo of you lying on your side on your pillow. Your head should look level with your spine, not tipped up toward the ceiling or down toward the bed.
Which fill holds up for side sleepers
| Fill or shape | Fits side sleepers who | Trade-off |
|---|---|---|
| Cervical contour foam | Want a set neck roll that does not flatten | Fixed height; must match your shoulder width |
| Solid latex | Want firm support that springs back and sleeps cooler | Not for anyone with a latex allergy |
| Shredded foam or latex with a zipper | Need to fine-tune height | Fill shifts; Cleveland Clinic notes shredded foam can lose stability over time |
| Buckwheat hulls | Want firm, moldable, cool support | Heavy and rustles when you move |
| Feather | Prefer a soft, squishy feel | Cleveland Clinic ranks it least supportive for neck pain |
Cleveland Clinic says cervical contour pillows work best for most people, with the higher side under the neck when you lie on your side. It also calls latex foam generally the best material because it supports without holding heat. For more detail on each, see our guides to contour pillows and latex pillows.
The rolled towel trick before you buy
You can test what height feels right before you buy. The Sleep Foundation suggests rolling a hand towel and sliding it along the long edge of your pillowcase, where your neck rests. You can reshape it to fill the space between the side of your face and your shoulder. Sleep on it for a few nights. If it helps, you have learned that you need more support under the neck than your current pillow gives, and roughly how much.
Setup tips that help the pillow work
- Keep the pillow under your head, not your shoulder. Your shoulder should rest on the mattress just below the pillow's edge.
- Hug a second pillow. Cleveland Clinic notes body and side pillows can help keep your spine aligned when you lie on your side. See our side sleeper wedge guide for more support ideas.
- Stop the roll onto your stomach. The Sleep Foundation suggests placing pillows around your body to keep from turning onto your stomach, the position it does not recommend for neck pain.
- Give a new shape time. A firm contour can feel odd for the first few nights after a soft pillow.
What to look for when you buy
Cervical contour memory foam pillow sized to your shoulder
Best for: Side sleepers who switch to their back and want one pillow for both
Cleveland Clinic says cervical contour pillows work best for most people, with a higher edge for side sleeping and a lower one for back sleeping. Some makers size them by shoulder measurement, which helps you match the gap.
Watch out: If the size is wrong, it is wrong every night. Measure first, and pick the smaller size if you fall between two.
See options on AmazonSolid latex pillow, medium to high loft
Best for: Side sleepers with broad shoulders who sleep warm
Cleveland Clinic calls latex foam generally the best pillow material because it supports without retaining heat. A solid piece keeps its height through the night instead of flattening.
Watch out: Skip natural latex if you have a latex allergy; memory foam is the usual alternative.
See options on AmazonAdjustable shredded fill pillow with zipper
Best for: People who are not sure what height they need
The Sleep Foundation notes some shredded memory foam and latex pillows have zippered covers so you can remove fill to change height and firmness.
Watch out: Shredded fill shifts during the night and can lose stability over time, so plush it back into shape and recheck the height.
See options on AmazonFull-length body pillow
Best for: Side sleepers who drift onto their stomach or have wide hips
Cleveland Clinic says body and side pillows help keep the spine aligned in a side-lying position, which takes twisting load off the neck.
Watch out: It adds support for the body, not the neck. You still need a head pillow of the right height.

- Should side sleepers with neck pain use a firm or soft pillow?
- Usually firm enough to hold its height all night. Cleveland Clinic ranks feather pillows least supportive because the fill shifts, while contour foam and latex keep their shape.
- How high should a pillow be for a side sleeper?
- High enough to fill the space from your ear to the edge of your shoulder, so your neck stays parallel to the mattress. Broader shoulders and firmer mattresses call for more height.
- Is it better to use two pillows when side sleeping?
- Stacking can work, but the Sleep Foundation cautions side sleepers against stacks that are too thick. A single pillow of the right height is more stable than two that slide apart.
- Which side is best to sleep on for neck pain?
- The sources we checked do not name a better side for neck pain. Alignment matters more than which side you choose, so pick the one that is comfortable and keep your neck level.
- How do I know my pillow is causing my neck pain?
- A clue is stiffness that is worst on waking and eases as you move. Try the rolled towel test or a photo of your sleeping position to see whether your head tilts up or down.
