Find the Right Height Before the Right Material
Your shoulder width and mattress softness decide how much loft you need. A broad-shouldered sleeper on a firm mattress often needs more height than a smaller sleeper on a soft mattress. Our pillow loft guide explains how that gap changes.
Your shoulder normally stays on the mattress, while the pillow supports the head and fills the open space above it. See where your shoulders should sit if the edge of your pillow keeps bunching under you. A shoulder cutout may create more room, but a regular rectangular pillow can also work when its loft is right.
Our Six Picks
1 / 6
Coop Original Cut-Out Pillow
Fill
Shredded memory foam and microfiber
Size
18 x 28 in
Loft
Adjustable
Cover
Removable washable Lulltra fabric
Coop combines a curved shoulder cutout with removable shredded memory foam and microfiber fill. An extra fill bag lets you build more height, while the zipper gives smaller sleepers a way to lower the profile.
Owners value that range, especially when a fixed pillow has felt too tall or too flat. The fill can take several tries to balance, and some sleepers still find the finished feel soft or warm, so adjustment matters more than the label alone.
Why It Works
- Removable fill changes both height and feel.
- The cutout leaves room along the shoulder edge.
- The outer cover can be removed for washing.
What To Keep In Mind
- The pillow arrives compressed and needs time to expand.
- Shredded fill needs occasional fluffing and redistribution.
2 / 6
Purple Harmony Medium Pillow
Core
Talalay latex
Surface
GelFlex grid
Loft
6.5 in medium
Care
Wash cover, spot-clean core
Purple pairs a Talalay-latex core with a flexible GelFlex grid and mesh cover. The medium model has a 6.5-inch profile, while lower and taller versions in the same range offer other fixed-height choices.
The result feels springy instead of slow-sinking, so it returns to shape quickly when you move. Some owners like its airflow and steady support, while others sink farther than expected or find the pillow too substantial for their frame.
Why It Works
- Latex rebounds quickly when a sleeper changes position.
- The grid and ventilated core allow air to move.
- Several height options make the range easier to fit.
What To Keep In Mind
- The selected height cannot be adjusted at home.
- Its dense materials make it heavier than a fiber pillow.
3 / 6
TEMPUR-Ergo Neck Medium Pillow
Core
Formed TEMPUR material
Size
20 x 12.5 in
Profile
4 in medium
Cover
Removable polyester knit
TEMPUR-Ergo uses a molded wave shape rather than loose or shredded fill. The medium version measures 20 by 12.5 inches with a four-inch profile, giving it a compact surface and a clear raised contour.
This is the firmest-feeling choice in the group. Owners who want a dense, steady shape appreciate that firmness, but others describe it as hard or smaller than the usual bed pillow, so its exact dimensions deserve close attention.
Why It Works
- Molded foam holds a consistent contoured shape.
- The raised edge provides a defined sleeping area.
- Its knit cover is removable and washable.
What To Keep In Mind
- Extra-firm foam offers little of the feel of a fluffy pillow.
- The compact dimensions may not suit restless sleepers.
4 / 6
Eli & Elm Side Sleeper Pillow
Fill
Latex noodles and polyester fiber
Shape
U-shaped shoulder cutout
Loft
Adjustable
Access
Zippered fill opening
Eli & Elm curves around the shoulder with a deep U-shaped edge. Its blend of latex noodles and polyester fiber can be removed through a zipper, so you can change the loft instead of accepting one fixed height.
Hot sleepers can compare more purpose-built options in the best cooling pillows roundup.
The pillow has a dense, structured feel that some owners find stable for side sleeping. Others report that it feels hard around the ear or becomes too thin after removing fill, and loose pieces can make adjustment messy.
Why It Works
- The U-shaped edge creates space for the shoulder.
- Removable fill allows a more personal loft.
- Latex pieces add spring to the softer fiber blend.
What To Keep In Mind
- Make small fill changes so the center does not become too low.
- Dense fill may press firmly around the face and ear.
5 / 6
Casper Hybrid Pillow with Snow Technology
Build
Foam layers and fiber core
Cover
92% polyester and 8% spandex
Cooling
Cool-touch fabric and heat-dispersing bands
Care
Removable knit cover
Casper builds this pillow with foam layers around a fiber core, then adds a cool-touch cover, phase-change material, and heat-dispersing bands. It feels more structured than an ordinary down-alternative pillow but less rigid than one solid foam block.
Owners disagree about how long the cool surface lasts. Some enjoy its support and cooler first touch, while others say it warms after several minutes or feels less full than expected, making it best for sleepers who also like its hybrid construction.
Why It Works
- Several cooling features address heat at the surface.
- Foam and fiber balance structure with some softness.
- The knit cover can be removed for cleaning.
What To Keep In Mind
- A cool first touch does not guarantee an all-night cold feel.
- Fixed fill gives you no way to raise the loft.
6 / 6
Honeydew Essence Side Sleeper Pillow
Fill
Gel-based memory foam
Shape
Curved shoulder edge
Loft
Adjustable
Construction
Made in California
Honeydew uses a curved lower edge and adjustable gel-based memory-foam fill. The shape gives the shoulder more room than a straight edge, while the fill opening lets you change the height and redistribute material.
Some owners like its moldable support and unusual shape. Others notice an initial foam odor, want a different amount of fill, or find that the curve works best with a case made for it, so plan for a short setup period.
Why It Works
- Adjustable fill helps correct a high or low starting loft.
- The crescent edge fits around the shoulder line.
- Loose foam can be moved to even out support.
What To Keep In Mind
- Air the pillow if you are sensitive to new-foam odor.
- A standard pillowcase may not follow the curved shape neatly.
Buying Guidance for Side Sleepers
Start with alignment. When you lie on your side, your head should not tip toward the mattress or away from it. The side-sleeping pillow guide offers a simple way to check fit at home, while our guide to firm versus soft side-sleeper pillows explains why firmness cannot correct the wrong height by itself.
Choose adjustable fill if you are unsure about loft or often change mattresses. Choose latex if you want quick bounce, molded foam for a fixed contour, or a hybrid if you prefer a mix of softness and structure.
Care also matters. Removable covers are convenient, but foam and latex cores usually need spot cleaning. Follow the label and use our guide on how to wash pillows before putting any full pillow in a machine. Replace a pillow when it no longer returns to its working shape or holds the height you need.
Frequently Asked Questions
What pillow height is best for a side sleeper?
The right height fills the gap between the head and mattress while keeping the head level. Shoulder width, body size, and mattress softness all change that gap.
Do side sleepers need a firm or soft pillow?
They need enough support to hold the correct height. A softer pillow can work if it stays tall enough, while a very firm pillow can still be wrong when its loft is too high or low.
Is a shoulder cutout necessary?
No. A cutout can leave useful room around the shoulder, but a regular rectangular pillow can work well when its height and firmness match the sleeper.
Are adjustable pillows good for side sleepers?
They can be helpful because fill can be added or removed as the mattress, sleep position, or comfort preference changes. Setup takes more effort than using a fixed pillow.
Is latex or memory foam better for side sleeping?
Latex feels springy and returns to shape quickly. Memory foam sinks more slowly and creates a closer contour. The better choice depends on the feel you prefer and the loft available.
Can a side-sleeper pillow also work for back sleeping?
It can if the loft compresses or adjusts enough for both positions. A tall fixed pillow that fits on the side may hold the head too high on the back.
How do I know if my side-sleeper pillow is too tall?
It may be too tall if your head tilts upward away from the mattress. A partner or a photo taken from behind can help you check whether your head stays in line with your torso.
Side sleepers who regularly change position can also compare the best adjustable pillows. If you mainly sleep face up or face down, use the dedicated guides for back sleepers and stomach sleepers.
Side sleepers who regularly change position can also compare the best adjustable pillows. Compare four pillows for back sleepers by loft, firmness, fill, adjustability, cooling design, and care to find support that does not push the head forward. Compare three low-profile pillows for stomach sleepers by height, foam density, firmness, cooling design, expansion, and cover care to find a flatter fit.
