Which pillow should a side sleeper with neck discomfort pick?
A side sleeper with neck discomfort should pick by fit: adjustable if unsure of height, contoured memory foam for a shaped neck rest, latex for springy firmness, down only for soft-pillow lovers. Fit depends on your sleeping position, shoulder width and mattress, so no pillow suits everyone. A pillow is a comfort product, not a treatment.

Adjustable fill pillow
An adjustable pillow suits side sleepers who don’t know their right height, or who switch between side and back. You scoop fill out until your head sits level. Skip it if you hate a lumpy, shifting feel.
Contoured memory foam pillow
A contoured memory foam pillow suits side sleepers who like a firm, shaped edge under the neck. Skip it if you want a flat, squishy pillow or you sleep mostly on your stomach.
Down, latex or polyfill alternatives
Latex suits people who like a springy, firm feel, and it did well in two small trials of side sleepers covered below. Polyfill is cheap and soft but flattens. A down/feather pillow suits soft-pillow fans with narrow shoulders, yet a 2009 trial of 106 side sleepers advised against feather pillows for waking neck pain.
How high should a side sleeper’s pillow be?
A side sleeper’s pillow should be tall enough to fill the gap between your ear and outer shoulder, about 4 to 6 inches once compressed. The goal is neutral alignment: head level with the spine, nose lined up with the middle of your chest. Our guide to the best pillow height for side sleepers goes deeper.
Loft by shoulder width
Pillow height (its loft) should grow with your shoulder width. These are starting points, measured after you lie on the pillow:
| Shoulder width | Medium mattress | Soft mattress | Firm mattress |
|---|---|---|---|
| Narrow | 4 to 5 in | about 4 in | about 5 in |
| Average | 5 to 6 in | about 5 in | about 6 in |
| Broad | 6 to 7 in | about 6 in | about 7 in |
A side sleeper with wide shoulders on a firm mattress might need a 7-inch pillow, while a petite person on a plush topper may be fine at 4.
Firmness and sink-in
Firmness decides how much of that height you keep at night. Down squashes a lot, so buy it taller than you need. Memory foam sinks slowly and holds most of its height. Our page on the best pillow firmness for side sleepers covers the feel of each fill.
Quick tip: Judge loft with your head on the pillow, not by the number on the box.
Do cervical and contour pillows work for side sleepers?
Cervical and contour pillows work for some side sleepers, but studies don’t show the shape beats a regular pillow. A cervical pillow is any pillow shaped for the neck, usually with a raised roll and a dip for the head.
What the shape does
A contour pillow puts a firmer roll under the neck and lets the head rest lower. Makers say this supports the neck for back and side sleepers. A 2021 review found cervical alignment may depend more on pillow shape and height than on the fill. For side sleepers, the higher edge must match your shoulder width, or your head tips down.
Where it falls short
A contour pillow isn’t a sure win. In a week-by-week trial, the foam contour pillow did no better than a regular foam one, while latex did best. A 2025 review of five small studies found no pillow type clearly better for chronic neck pain. Memory foam can also feel warm and slow to respond, so look for a cooling cover.
What if shoulder pain is the main problem?
If shoulder pain is the main problem, choose a firmer, taller pillow so your shoulder isn’t jammed up toward your ear, and avoid lying on the sore side when you can.
Pillow choice for a sore shoulder
The right pillow lets your shoulder sit just below or beside it, not squashed under it. Cut-out or winged shapes are made for this. A pillow that’s too low forces the shoulder to carry your head’s weight.
Sleeping position and extra support
Sleep on the pain-free side and hug a body pillow so your top arm doesn’t fall forward. A knee pillow keeps your hips stacked, which stops you rolling. If you change positions a lot, pick an adjustable or mid-height pillow that also works on your back. A side sleeper with a sore right shoulder, for example, might sleep on the left, hugging a long pillow, with a cushion between the knees.
How to test pillow height at home
You can test pillow height at home with a partner, a phone camera and a towel.
- Lie on your side in your usual sleep clothes, on your own mattress.
- Ask someone to photograph you from behind or from the front.
- Check that your nose lines up with the middle of your chest and your neck runs straight from your back.
- Head tipping down? Slide a folded towel under the pillow. Tipping up? Remove fill or try a lower pillow.
- Measure the stack once it looks level. That’s your target loft.
Give a new pillow one to two weeks unless it clearly hurts. Before buying, read the sleep trial terms: what condition the pillow must be in, who pays return shipping, and which fees aren’t refunded. If you woke up sore after a bad night, see how to alleviate neck pain from sleeping wrong.
Why does my neck hurt no matter what pillow I use?
Neck pain that stays the same with every pillow often isn’t a pillow problem. Your mattress, daytime posture, stress and long screen time can all play a part.
Mattress, posture and tech neck
A sagging or very hard mattress changes how your shoulder sinks, which throws off any pillow. Tech neck, the strain from looking down at a phone for hours, builds up by day, and no pillow can correct posture. Morning stiffness and headaches have many causes; our guide to stiff neck pain after sleeping walks through them.
Signs it is not a pillow problem
See a doctor first if neck pain lasts more than a week or two, spreads into an arm, comes with numbness, tingling, weakness or headaches, or follows an injury. MedlinePlus lists these warning signs. Loud snoring with gasping or pauses in breathing also needs a doctor, since these can be signs of sleep apnea. If a doctor says your snoring is worse on your back, side-sleeping can help some people, and a good pillow can make side-sleeping comfortable.
Contoured memory foam option: Derila Ergo
Derila Ergo is a contoured memory foam pillow that stands out for its neck-shaped curve and low price per pillow.
What it is
Derila Ergo measures 54 x 36 x 12 cm (21.2 x 14.1 x 4.7 in) and arrives vacuum-packed; give it 6 to 8 hours to expand. Side sleepers rest the front curve against the side of the neck. The maker says the memory foam contours to your shape and the cover and breathable foam help keep it cool and dry. The maker hasn’t published a study of Derila Ergo itself. For a fuller look, read our ergo memory foam pillow review.
Price and return terms
One pillow is $59.99, two are $99.98 and the family pack of four is $149.96 (checked on the official site on November 4, 2026; prices change often). The maker advertises a 60-day return policy from when you receive the order. Non-defective pillows must come back in manufacturer’s condition, in original undamaged packaging, after you fill in the RMA form. You ship it to the RMA address with tracking, shipping costs aren’t refunded, and the refund arrives within 14 days of inspection. Keep the packaging.
Who should skip it
- You love a flat, soft pillow or need more than 4.7 inches of height.
- You sleep very hot.
- You sleep mostly on your stomach.
- You have lasting pain, arm symptoms or breathing concerns: see a doctor first.
- Babies: no pillow goes in a baby’s sleep space, per Safe to Sleep.
It doesn’t treat neck pain, shoulder pain, snoring or sleep apnea.

Questions readers ask
Is memory foam or latex better for side sleepers?
Both can suit side sleepers. Memory foam sinks slowly and holds its shape, which many people like for a steady neck rest. Latex feels springier and bounces back fast, and it tends to sleep cooler. Pick memory foam for a hugging feel and latex if you change positions often or run warm.
How often should I replace a pillow?
Most pillows need replacing every one to two years, and good foam or latex may last longer. Replace sooner if it stays flat, has lumps, smells, or no longer passes the head-level test when you lie on your side. Washing the cover often helps any pillow stay fresh longer.
Should I use a pillow between my knees?
A pillow between your knees helps many side sleepers stay stacked at the hips, so you don’t twist your lower back or roll forward onto your shoulder. Choose one firm enough to keep your knees about hip-width apart. It’s an easy, low-cost addition to any head pillow.
