If you sleep on your side and wake with a stiff neck, an aching shoulder or a numb arm, your pillow is one of the first things worth checking. Side sleeping leaves a gap between your head and the mattress that the pillow has to fill. Too little and your neck bends down toward the bed; too much and it bends up, and you hold that position for hours. The best pillow for side sleepers fills that gap at the right height for your shoulder width.
I spent years as a physical therapist before reviewing sleep products, and neck position in side lying is something I looked at constantly. For this guide I compared seven pillows on their published construction, loft options, firmness, sizing, trial and warranty, and matched them to frame size using general ergonomics.
Our quick answer: the Naturepedic Organic Latex Side Sleeper Pillow is the purpose-built pick if you know your fit, and the Coop Home Goods Original is the safest bet if you don't. New to choosing loft and fill? Start with how to choose a pillow.

How We Chose
- Loft and adjustability. Can the pillow reach the height a side sleeper needs, and can it be changed (adjustable fill, two heights or size options)?
- Shape and support. Solid, shredded or contoured; whether the shape is designed around side lying.
- Materials and heat. Fill type and cover, judged on how they're built for airflow, not on measurements.
- Frame fit. Which shoulder widths each design is likely to suit, based on loft and how much the fill compresses.
- Policies and price. Trial length, warranty and cost, taken from each review.
Every product fact here matches our individual reviews; see our editorial methodology for how we rate products.
Why Side Sleepers Need a Different Pillow
When you lie on your side, your shoulder presses into the mattress and lifts your head off it. The pillow's job is to fill that space so your head stays level with your spine.
- Too low: your head drops toward the mattress, side-bending the neck.
- Too high: your head tilts up and away, bending the neck the other way.
- About right: your nose lines up with the middle of your chest and your neck looks like a continuation of your spine.
Because the gap depends on your shoulder width and your mattress, there is no single best height. That's why this guide matches pillows to body types rather than crowning one winner for everyone.

How to Choose a Pillow for Side Sleeping
How high should a side sleeper's pillow be?
Start with your shoulder width. The wider your shoulders, the taller the pillow needs to be. These are general starting points, not measured results; fine-tune from there:
| Body type | Approx. shoulder width | Loft that often works |
|---|---|---|
| Petite | Under 16 in | Low to medium (about 4–4.5 in) |
| Average | 16–18 in | Medium (about 4.5–5.5 in) |
| Broad | Over 18 in | Medium-high to high (5.5 in+) |
How does your mattress change the loft you need?
A soft mattress lets your shoulder sink in, so you need a lower pillow. A firm mattress keeps your shoulder high, so you need a taller one. We can't give a precise inch figure for this, because it depends on your body and the specific mattress, but if you change mattresses, recheck your pillow. Our mattress firmness guide and best mattress for side sleepers explain how firmness affects alignment.
Adjustable, fixed or two-height?
- Adjustable fill (Coop Original, Coop Cool+, Nuzzle, Marlow): add or remove fill until the height is right. Best if you're unsure.
- Purpose-built fixed loft (Naturepedic, Purple Harmony): a consistent shape that works if the size fits you.
- Two-height design (TEMPUR-Ergo, Eli & Elm): flip or turn the pillow to switch between a lower and higher side.
Adjustable is safer until you know your number. Once you do, a purpose-built pillow is a reasonable next step.
Should side sleepers use a firm or soft pillow?
Firmer, fuller pillows tend to suit side sleepers because they hold their height under the head; soft pillows compress and let the neck drop. Petite frames, where the gap is small, can sometimes get away with softer pillows.
Which pillow fits your situation?
Broad shoulders: the Coop Original or Nuzzle with most of the fill in, the Purple Harmony's high loft, or the TEMPUR-Ergo in a larger size. Avoid soft, low pillows.
Petite: an adjustable pillow with fill removed, or the Purple Harmony's low loft. Avoid tall fixed pillows.
Neck stiffness: start with loft, not material. The Naturepedic and Eli & Elm are shaped for side lying, and adjustable pillows let you fine-tune. See our best pillow for neck pain guide, and see a doctor if pain is severe or persistent.
Hot sleepers: the Coop Cool+ and Purple Harmony are designed for airflow. Dense molded foam (TEMPUR-Ergo, Eli & Elm) tends to hold more heat. See our best cooling pillow guide.
Pregnant: a full-body pregnancy pillow supports the bump, back and knees as well; see our best pregnancy pillow guide.
Signs Your Pillow Is Wrong
Adjust or replace your pillow if you regularly notice any of these:
- You wake with neck tension that eases as the day goes on.
- Your bottom shoulder feels squashed, or that arm goes numb.
- Someone can see your head tipping up or down when you lie on your side.
- You keep folding, stacking or punching the pillow to change its height.
- The pillow no longer springs back after you fold it in half.
Symptoms that are severe, spread down your arm or come with weakness should be checked by a doctor rather than treated with a new pillow.
Final Verdict
If you know your fit, the Naturepedic Organic Latex Side Sleeper Pillow is the most purpose-built side-sleeper pillow we cover: solid, certified-organic latex shaped for one position.
If you're unsure of your loft, start with the Coop Home Goods Original and tune it to your shoulders. Hot sleepers should look at the Coop Cool+ or, at a premium, the Purple Harmony; couples can save with the Nuzzle set.
Frequently Asked Questions
What is the best pillow for side sleepers?
It depends on your shoulder width and mattress. If you know your fit, the Naturepedic Organic Latex is our purpose-built pick; if not, an adjustable pillow like the Coop Home Goods Original is the safest choice.
How high should a side sleeper pillow be?
High enough to fill the gap between your ear and the mattress, keeping your nose in line with your chest. As a starting point, roughly 4–4.5 inches for petite frames, 4.5–5.5 inches for average frames and 5.5 inches or more for broad shoulders.
Should side sleepers use a firm or soft pillow?
Usually a firmer, fuller pillow that keeps its height under the head. Too soft lets your neck drop; too firm and tall can push your head up.
Is a thick pillow better for side sleepers?
Not always. Thick pillows suit broad shoulders and firm mattresses, but a pillow that's too tall bends your neck upward.
Match the thickness to the gap you need to fill.
I'm between average and broad shoulders. How do I decide?
Start with an adjustable pillow rather than betting on a fixed size. Keep most of the fill in, then remove a little at a time until your neck feels level.
Does mattress firmness change the pillow loft I need?
Yes. A softer mattress lets your shoulder sink, so you need less loft; a firmer one keeps it higher, so you need more.
If you've changed mattresses, reassess your pillow.
What's the best pillow for side sleepers with neck pain?
There's no pillow that treats neck pain, but one that holds the right height helps you avoid a bent neck. Shaped side-sleeper pillows (Naturepedic, Eli & Elm) and adjustable ones (Coop Original) are good starting points.
If pain persists, see a doctor or physical therapist.
Should I put a pillow between my knees?
Many side sleepers find it keeps the hips and lower spine more comfortable. It's separate from your head pillow, which is the focus of this guide.
How often should side sleepers replace their pillow?
As a general guide, about 1–2 years for fiber, 2–3 years for memory foam and 3 years or more for latex. Replace any pillow that stays folded or no longer holds your head at the right height.
