Side sleeping feels natural to many people, but it asks a lot of a pillow. Your pillow has to fill the gap between your head and shoulder so your neck stays straight all night; too flat and your head drops, too tall and it tilts up. The wrong loft is a common reason people wake up with a stiff neck.
We built this guide from two independent sources. Good Housekeeping’s Textiles Lab tested 200 pillows, combining at-home feedback from more than 1,000 consumer testers with lab wash tests and weighted pressure tests for shape retention. CNET’s sleep reviewer tested 30 or more pillows for at least two nights each, sleeping on her side. We haven’t tested these pillows ourselves, and pillow comfort is personal, so check return policies.
Quick answer: Good Housekeeping’s best overall is the Pillow Cube Side Cube, and its best for neck pain is the adjustable Coop Home Goods Original. CNET’s best overall is the Purple Harmony, also Good Housekeeping’s best cooling pick. For the classic sink-in luxury feel, Good Housekeeping recommends the Tempur-Pedic Tempur-Adapt Pro.

What side sleepers need in a pillow
Good Housekeeping cites Dr. Jaspal R. Singh of Weill Cornell Medicine: side sleepers should choose a thick, firm pillow that keeps their ears in line with their shoulders so the neck doesn’t bend either way.
Loft: the right height depends on your build and shoulder width. Good Housekeeping suggests lying on your side with books under your head, adding or removing them until you’re aligned, then measuring the stack as a rough guide. Adjustable pillows remove the guesswork.
Fill: solid foam and latex give the most uniform support; shredded, down and down-alternative fills are more moldable but may need fluffing. CNET recommends memory foam, polyfoam or latex for side sleepers because they stay lofty, and warns that very cheap down-alternative pillows can fall flat.
Sleep style: restless sleepers do better with moldable fills; if you stay on your side all night, a solid foam pillow can hold your head in one position.
The best pillows for side sleepers
1. Pillow Cube Side Cube: best for dedicated side sleepers
Best for: people who sleep on their side all night.
Good Housekeeping’s best overall uses a rectangular shape with 90-degree edges to fill the space between shoulder and neck. Despite initial skepticism, it impressed both the Textiles Lab and consumer testers, and its foam held up under pressure. It comes in one 5-inch height (the Side Cube Deluxe offers more heights), and it’s not ideal if you change positions. Only the cover is machine washable.
Pros
- Purpose-built shape
- Foam holds up
- Excellent alignment
Cons
- One height
- Not for combination sleepers
2. Purple Harmony Pillow: best cooling luxury pillow
Best for: hot side sleepers.
CNET’s best overall combines Purple’s open-cell GelFlex Grid with Talalay latex; its reviewer slept on it for a month and found a soft, squishy top over a supportive latex core, with excellent airflow. It comes in low, medium and tall lofts; CNET suggests tall for most side sleepers and medium for side sleepers under 150 pounds.
Good Housekeeping’s best cooling pick earned some of its highest tester scores for support and bounced back quickly in pressure tests; hot sleepers said it kept them comfortable. It’s heavier than most pillows and expensive.
Pros
- Cool, airy feel
- Three lofts
- Supportive latex core
Cons
- Expensive
- Heavy
- Unusual feel
3. Coop Home Goods Premium Original Adjustable: best for neck pain
Best for: anyone unsure of their ideal loft.
You add or remove the shredded memory foam and polyester cluster fill until the height and firmness feel right. Good Housekeeping says it was a top performer in the Textiles Lab and a favorite among testers with neck pain; both the cover and inner pillow are machine washable and looked great after washing. The outer cover pills over time. CNET also likes Coop’s EdenCool Plus as a cooler adjustable alternative.
Pros
- Fully adjustable
- Machine washable
- Great value
Cons
- Cover pills
4. Tempur-Pedic Tempur-Adapt Pro: best memory foam splurge
Best for: fans of a deep, sink-in feel.
Good Housekeeping says nothing beats Tempur-Pedic foam’s supportive, sink-in feel, and the material bounces back with continued use. It comes in high and low heights; high is ideal for side sleepers. A gel layer helps with cooling, and the cover showed no significant wear after lab washing. It’s slow to recover if you move, and it’s the priciest pillow on Good Housekeeping’s list.
Pros
- Signature Tempur feel
- Two heights
- Durable
Cons
- Priciest
- Slow response
5. Layla Kapok Pillow: best for combination sleepers
Best for: people who shift between side and back.
Its adjustable fill mixes kapok, a silky natural fiber, with shredded memory foam. Good Housekeeping’s testers gave it near-perfect scores for comfort, support and satisfaction, and noted cooling. CNET names it its best memory foam pillow for side sleepers. The gray cover can show through light pillowcases, and it may be too thin for broad shoulders.
Pros
- Adjustable
- Soft yet supportive
- Cool
Cons
- May be thin for broad shoulders
6. Naturepedic Organic 2-in-1 Adjustable Latex: best organic pillow
Best for: shoppers who prioritize certified materials.
Good Housekeeping highlights GOLS and GOTS organic certifications. It’s reversible, with quilted plant-based batting on one side and adjustable shredded latex on the other, inside an organic cotton cover. Some testers found adjusting the fill messy.
Pros
- Organic certifications
- Reversible
- Adjustable
Cons
- Messy to adjust
7. Sleep Number ComfortFit (Ultimate): most customizable
Best for: fine-tuning firmness and height.
CNET found its memory foam and fiber blend supported the neck and reduced shoulder strain, so the tester repositioned less. The Ultimate shape includes three inserts for customizing support and height, and there’s a Curved version for side sleepers. The cover is hypoallergenic Lyocell blend and machine washable. It feels heavy, and all three inserts can make it snug in a standard pillowcase.
Pros
- Highly customizable
- Washable hypoallergenic cover
Cons
- Heavy
- Snug with all inserts
8. Beckham Hotel Collection: best value
Best for: budget-minded shoppers and guest rooms.
Good Housekeeping says it outperformed pillows triple its price. It has polyester down-alternative fill in a cotton cover and is entirely machine washable. Testers liked that it kept its shape without clumping, though some found it too flat for neck support, and it may not suit larger frames.
Pros
- Inexpensive
- Fully washable
Cons
- Less supportive
- One height
Other options
Good Housekeeping also recommends the Saatva Latex Pillow, a gusseted 6- to 7-inch shredded latex pillow with an organic cotton sateen cover, and the Pluto Puff Body Pillow for full-body alignment. CNET likes the Casper Hybrid with Snow as its best cooling pick and the Eli & Elm Side Sleeper Pillow for neck pain.
Make the whole bed work together
Pillow loft interacts with your mattress: a softer mattress lets your shoulder sink, so you may need slightly less loft. See our best luxury mattresses, best mattress toppers and, for hot sleepers, best cooling mattresses. Finish with a smooth pillowcase; we ask are silk pillowcases worth it?
FAQ
What loft do side sleepers need?
Enough to keep your ears in line with your shoulders. Broader shoulders usually need a taller pillow; adjustable pillows help.
Are memory foam pillows good for side sleepers?
Yes. Solid foam gives uniform support; shredded foam is adjustable and more moldable.
Can I wash my pillow?
Often only the cover. Good Housekeeping notes memory foam is usually not machine washable, while down-alternative pillows like the Beckham are.
What if I switch positions?
Choose an adjustable or moldable pillow such as the Coop or Layla rather than a rigid side-specific shape.
The bottom line
If you sleep on your side all night, the Pillow Cube Side Cube is purpose-built for you. Hot sleepers should choose the Purple Harmony, and anyone unsure of their ideal height should start with the adjustable Coop. For pure luxury, the Tempur-Adapt Pro delivers the classic sink-in feel.
