For the best side sleeping pillow for neck pain, start with the Coop Home Goods Original Cut-Out Adjustable Pillow: the shoulder cut-out and adjustable fill address the two things that go wrong for side sleepers, a shoulder pushing the head up and a loft that is the wrong height. If you have broad shoulders, the Hcksviam high-loft pillow is the runner-up for your frame.
Side sleeping is a position where the pillow has to do all the work of aligning the neck, because nothing else supports the head. This guide takes a loft-first approach: instead of ranking by brand, it sorts pillows by shape, height and fill and shows which shoulder width each suits. We did not personally use these products, nothing here is medical advice, and where specs were not published we say not listed.

1. Coop Home Goods Original Cut-Out Adjustable Pillow: Best Overall for Side Sleepers
- Size: queen, listed at 18 x 28 in
- Feel: medium firm, listed for side sleepers
- Fill: memory foam, adjustable
- Shoulder cut-out so your shoulder can tuck under the pillow
- Certifications named by the maker: CertiPUR-US and GREENGUARD Gold
Best for: side sleepers who want a shoulder cutout and adjustable fill. Skip if: you sleep mostly on your back or stomach.
The main problem with side sleeping and a neck that complains is the shoulder. When your shoulder is pushed up against the pillow, the pillow tilts your head. A cut-out lets the shoulder slide under the pillow edge, so your head can rest closer to the mattress surface and your neck stays level.
Coop’s cut-out version keeps the adjustable fill of the Original and adds that shoulder notch. The adjustable fill matters here: a cut-out pillow that is too tall pushes your head sideways just as a flat one pulls it down, so being able to remove a little fill is useful.
Because the shape is specific, it is a poorer choice if you roll onto your back often; the cut-out leaves a small gap. For committed side sleepers, it is the most balanced design on this list.
Pros
- Shoulder cut-out
- Adjustable loft
- Certified foam
Cons
- Not for back or stomach sleeping
- Higher price than basic foam
2. Mellow CloudAlign Memory Foam Pillow: Best Dual-Height Contour
- Shape: contoured, dual-height design
- Fill: memory foam
- Cover: washable
- Listed for side, back and stomach sleepers, with neck and shoulder support
- Exact heights: not listed
Best for: side sleepers who also lie on their back and want two heights in one pillow. Skip if: you prefer a soft, shredded feel.
A dual-height contour has a taller edge and a lower edge, so you choose which side faces up depending on whether you are lying on your side or back. That makes it more flexible for people who change position through the night.
The listing does not publish the heights in inches, so check the seller photos and the maker page before buying. Based on the design, we would aim it at average-to-narrow shoulders; very broad shoulders would be better with a taller option below.
It is a good middle pick when you do not want to manage loose fill but still want some flexibility.
Pros
- Two heights
- Easy care
- Contoured
Cons
- Heights not listed
- Not for very broad shoulders
3. KUCEY Cooling Side Sleeper Pillow (Crescent, Shredded Memory Foam): Best Crescent Shape
- Shape: crescent curve
- Fill: luxury shredded memory foam, adjustable
- Size: queen
- Cover: washable, marketed as cooling
- Loft in inches: not listed
Best for: side sleepers who like a curved shape that hugs the neck and shoulder. Skip if: you want a flat or traditional rectangular pillow.
A crescent pillow curves around your neck and under the ear, and its rounded end lets your shoulder sit in the curve. For many side sleepers it is the quickest way to stop the head from dropping and the shoulder from jamming into the pillow.
KUCEY’s version uses shredded memory foam so you can change how full it is. This is helpful because a crescent that is overfilled turns into a firm tube, while an underfilled one slumps.
Expect to fluff the pillow before bed and to reposition the foam once or twice in the first week.
Pros
- Curved shoulder fit
- Adjustable fill
- Washable cover
Cons
- Needs fluffing
- Specs thin
4. Hcksviam High Loft Pillow for Side Sleepers with Broad Shoulders: Best for Broad Shoulders
- Design: high loft pillow for broad shoulders
- Fill: extra firm tall memory foam
- Dual height configuration listed
- Cover: washable
- Exact heights: not listed
Best for: bigger-framed side sleepers who bottom out on standard pillows. Skip if: you have narrow shoulders or sleep on your back.
If you have broad shoulders, standard pillows often do not reach high enough, so your head tips down toward the mattress and the neck bends. A high-loft pillow is built to close that wider gap.
The risk is overshooting. A pillow that is too tall pushes your head up and over, which is just as uncomfortable. The dual height design gives a small amount of choice, but we still recommend trying it only if you already know that regular pillows are too low.
The exact heights are not listed in the summary we reviewed, so confirm the dimensions on the maker page.
Pros
- Built for broad frames
- Dual height
- Firm support
Cons
- Too tall for many
- Heights unconfirmed
5. JOODOU Extra Tall 6.5 Inch Memory Foam Pillow: Best Tall Budget Option
- Height: 6.5 in listed
- Fill: memory foam
- Marketed for side sleepers and shoulder support
- Cover details: not listed
- Firmness rating: not listed
Best for: side sleepers who need height at a modest cost. Skip if: you prefer an adjustable, soft pillow.
The 6.5 inch height listing puts this pillow in the range of a tall pillow for broad or average-to-broad shoulders. It is a simple, no-frills shape that suits someone who has already worked out that they need height.
Without adjustable fill it is a bet on one number, so measure the gap from your ear to the mattress while lying on your side before ordering. If that gap is near 6 inches or more it is a reasonable match.
Pros
- Clear tall height
- Simple design
- Mid-range price
Cons
- Fixed height
- Details limited
6. QUTOOL Cooling Crescent Side Sleeper Pillow: Best Crescent with Shoulder Cutout
- Shape: crescent with curved shoulder cutout
- Fill: adjustable shredded memory foam
- Cover: dual-sided cool-touch, washable
- Sizes: standard and queen listed
- Loft in inches: not listed
Best for: warm side sleepers who want a curved, adjustable shape. Skip if: you need a very firm pillow.
QUTOOL combines the curve of a crescent with a shoulder cutout, so the shoulder has room without removing support under the neck. The dual-sided cover has a cooler face for warm nights.
Like other shredded designs it needs fluffing, and the listing does not give the exact loft. Treat it as a cost-conscious alternative to the KUCEY.
Pros
- Cooling cover
- Shoulder cutout
- Lower cost
Cons
- Fluffing needed
- Loft unconfirmed
7. Casper Essential Cooling Foam Pillow: Best Firm Foam Block
- Fill: firm memory foam
- Cover: cooling
- Listed as supporting side sleepers, pressure-relieving
- Standard and king sizes listed
- Exact loft: not listed
Best for: side sleepers who prefer a solid foam pillow rather than loose fill. Skip if: you want adjustability.
A solid foam block does not shift or clump. Casper lists this as a firm pillow aimed at side sleepers, which suggests it is intended to hold its height rather than compress.
The trade-off is that you cannot change the loft, and the loft figure is not published in the summary we reviewed. It is a sensible choice for anyone who dislikes loose fill and has found firm foam comfortable in the past.
Pros
- Solid, no fluffing
- Cooling cover
- Firm support
Cons
- Fixed height
- Specs limited

How We Chose
We began by asking what makes a pillow suitable specifically for a sore neck while sleeping on the side. The answer is a combination of height, shape and stability: it must fill the ear-to-shoulder gap, avoid shoving the head upward, and hold that shape all night.
We then picked real products currently sold in four shape families: cut-outs, crescents, tall blocks and dual-height contours, and checked maker pages and listing details for specs. Independent sleep-review sites were used for general context. This guide is research-based, and we did not personally use these products. Where heights or firmness were not published, we say so.
Prices are shown as tiers only, and we capped each brand at two entries. We avoided products with no clear description of their fill or shape, and we skipped pillows sold only as part of a bundle, since they are harder to compare fairly. Each entry lists what we could confirm and what we could not, so you can see where a claim is the maker claim rather than something independently verified.
Buying Guide
Work out your loft number
Lie on your side on your mattress and have someone measure the gap between the mattress and the side of your head, or take a photo from behind. That distance, minus a small amount for compression, is your starting loft. A smaller gap of about 4 inches points to low pillows, about 5 to 6 inches to medium, and 6 inches or more to tall ones.
Pick a shape
Cut-outs and crescents make room for the shoulder and are good if the shoulder tends to push the pillow up. Contours with a raised edge are good if you switch between back and side. Straight rectangles suit sleepers who like to move the pillow around.
Choose adjustable or fixed
Adjustable fill, flip heights and removable layers reduce the risk of buying the wrong height, but loose fill needs fluffing. Solid foam blocks stay put but cannot be changed. If you have never owned a side sleeper pillow, adjustable is the safer first pick.
Think about firmness
Side sleepers generally do better on medium-firm to firm pillows, because soft ones compress under the weight of the head. Extra firm can feel unforgiving, so check the return policy.
Plan the trial period
Before buying, read the return terms. Foam pillows are often non-returnable once opened at some sellers, while others offer a trial. Because side sleeper pillows are shape-specific, a trial matters more than it does for a basic rectangle. If you must buy without a trial, prefer adjustable models, which can be tuned instead of returned.
Also note what size you are ordering. Queen and standard cut-outs can differ in length by several inches, and a crescent that is too short can leave your shoulder unsupported. Check the listed dimensions against your pillowcase size.
Care and odor
New foam can have a faint smell for a few days. Air it out of the bag, in a ventilated room, before first use. Covers listed as washable can go in a gentle cycle; the foam itself should not be machine washed. Shredded foam can be spot cleaned and left to dry flat.
Pair it with your mattress
Softer mattresses let the shoulder sink, lowering the gap. Firmer mattresses raise it. If you recently changed your mattress, re-check your loft number.
Quick Matching Table and What to Avoid
| Ear-to-mattress gap | Shoulder frame | Pillow to look at |
|---|---|---|
| About 4 in | Narrow | Mellow CloudAlign low side, QUTOOL with fill removed |
| About 5 to 6 in | Average | Coop Cut-Out, KUCEY, Casper Essential Cooling Foam |
| 6 in or more | Broad | JOODOU 6.5 in, Hcksviam high loft |
Avoid stacking two thin pillows, because the stack slides apart. Avoid very soft pillows if you need height, and avoid fixed tall pillows if you are unsure of your loft. If you wake with a numb arm or radiating pain, ask a doctor or physical therapist rather than relying on a pillow.
Setting Up the Whole Side-Sleeping Position
The pillow is only one piece of side-sleeping alignment. A second pillow between the knees keeps the top leg from pulling the hips forward, which in turn reduces twisting up the spine toward the neck. A thin pillow or rolled towel against the chest can stop you from rolling forward onto your shoulder.
Mind your arm position. Sliding the bottom arm forward, rather than under the head or pillow, avoids pressure on the shoulder and the nerves in the arm. An arm-hole pillow helps with this, but even a regular pillow works if you get in the habit of placing the arm out in front.
Your mattress matters as much as your pillow. If the mattress is too firm, the shoulder cannot sink, and the gap between ear and mattress grows. A mattress topper of a couple of inches can lower that gap and let you use a lower, more comfortable pillow. If the mattress is too soft, the hips sag and the whole spine curves; in that case a firmer surface helps more than any pillow.
Finally, notice how you wake up. Waking with one ear or one shoulder sore points to height or firmness. Waking with a stiff neck on the side opposite to the one you slept on often means the pillow tipped your head upward. Small changes, such as removing a handful of fill, are usually enough to correct this.
When to Replace Your Side Sleeper Pillow
Foam pillows often hold shape for a couple of years, while loose fill needs fluffing and eventually thins. Signs of wear include a permanent dent where your head goes, a smell that remains after washing the cover, and waking up with discomfort that you did not have when the pillow was new. A pillow protector under the pillowcase extends life, and rotating or flipping the pillow weekly keeps wear even.
Frequently Asked Questions
What is the best pillow for neck pain when sleeping on your side?
A pillow that fills the ear-to-shoulder gap and keeps your head level, usually medium-firm and with a shoulder cut-out or adjustable height, such as the Coop Cut-Out.
How thick should a side sleeping pillow be?
Between about 4 and 7 inches, depending on shoulder width. Measure your gap while lying on your side.
Is a crescent pillow good for side sleepers?
Yes for many, because the curve cradles the neck and leaves room for the shoulder. It can feel odd if you also sleep on your back.
Do cut-out pillows work?
They let the shoulder tuck under the pillow edge, which can keep the head from being pushed up. They work best for people who stay on their side.
Should the pillow be firm or soft?
Usually medium-firm to firm. Soft pillows compress and let the head drop.
How long until a new pillow feels right?
Many sleepers need several nights to a week to adjust, because the neck muscles are used to the old position.
Can I use a regular pillow if I add a rolled towel?
You can as a short-term fix, placing a small rolled towel under the pillow edge to add height, but a purpose-built side sleeper pillow is more stable and less likely to shift overnight.
Are cooling covers worth it?
They can help if you wake warm, though the foam inside still holds heat. Ventilated or shredded fill plus a breathable cover works better than a cover alone, and the effect varies between sleepers.
When should I see a doctor?
If pain is severe, lasts, follows an injury, or comes with numbness or weakness. A pillow is not a treatment.
Which One Should You Buy?
Choose the Coop Cut-Out if you want one balanced side-sleeper pillow with adjustable fill. Choose the KUCEY or QUTOOL if you like a crescent and sleep warm. Choose the Hcksviam or JOODOU if you have broad shoulders and know your gap is tall. Choose the Mellow if you move between side and back, and the Casper if you want a solid foam block.
If you are stuck between two options, pick the adjustable one. A pillow that can be changed will almost always end up closer to right than a fixed pillow chosen by guesswork. Re-check your choice after a month, since foam softens slightly with use and your sleeping habits may shift with the seasons.
Whichever you pick, buy from a seller with a clear return window and give the pillow a full week. Keep notes on the height or fill level that felt best so you can reproduce it after washing the cover or when the foam settles over the first few weeks of use.
