Quick answerAn adjustable cooling pillow is filled with loose pieces, usually shredded foam, shredded latex or buckwheat, inside a zippered cover, so you can take fill out or add it back to get the height right. That loose fill is also why these pillows tend to run cooler: air moves between the pieces. Start full, remove a little at a time, and pair it with a breathable cover.

Why adjustable and cool go together

The Sleep Foundation explains that solid foam generally holds more heat than shredded foam, because air moves more freely through loose fill. Its memory foam pillow guide says shredded pillows leave more room for airflow and can be adjusted to nearly any height, while one-piece pillows are usually firmer, hold their shape better and come at a medium to high loft.

So the feature that lets you set your height also helps heat escape. Many adjustable pillows add a cooling cover or gel-infused pieces on top of that.

Fill options compared

FillCoolingFeel and trade-offs
Shredded memory foamCooler than solid memory foamSoft, conforming; may need reshaping when you change position
Shredded latexLatex is more breathable than synthetic foamSpringier, bouncier; not for latex allergies
Buckwheat hullsOpen hulls create air pockets that prevent heat buildupFirm, heavy, rustles
Gel-infused shredded foamConductive gel pieces; benefit hard to judge in advanceSame as shredded foam
Down alternative clustersLess likely to retain heat than downSoft; can flatten

Cooling notes are from the Sleep Foundation's cooling and memory foam pillow guides. Its side sleeper guide adds that most buckwheat pillows can be adjusted for loft by adding or removing kernels.

How to adjust it, step by step

  1. Know your target. The Sleep Foundation says most side sleepers need at least 4 inches, stomach sleepers usually do best below 3 inches, and 3 to 5 inches is medium loft.
  2. Start with all the fill in. Fluff the pillow fully and sleep on it one night.
  3. Remove a handful at a time. Take out a small amount, zip it up, and lie in your usual position. Your neck should be level with the mattress.
  4. Give each change a few nights. Judge each change by how your neck feels in the morning, not in the first minute.
  5. Keep the extra fill. Store it in a bag or pillowcase. Fill compresses over months, and you may want to top it up.

If you switch positions, the Sleep Foundation notes that someone who sleeps partly on their stomach will probably need more fill for the back and side positions. See pillows for side and stomach sleepers.

Care

One of the advantages of shredded fill: the Sleep Foundation says some shredded memory foam pillows can be machine washed, while most one-piece pillows are spot-clean only. Check the label, and make sure foam dries completely, since damp foam can grow mold. Fluff the pillow regularly; it says this extends a shredded pillow's life. The average memory foam pillow lasts 2 to 3 years.

Who should choose something else

If you want a pillow that never needs fluffing, choose a solid latex pillow instead; it is also breathable but holds a fixed shape. If you need a very low pillow for stomach sleeping, a thin pillow may be simpler. For a full comparison of cool fills, see cool pillows, and for foam specifics see memory foam cooling pillows.

Adjustable shredded latex pillow

Best for: Hot sleepers who want a bouncier, springier feel

The Sleep Foundation says latex is more breathable than synthetic foam, and shredded latex lets you set the height.

Watch out: Not for anyone with a latex allergy.

Buckwheat pillow with zipper

Best for: Hot sleepers who want firm, moldable support

Buckwheat hulls create air pockets that prevent heat buildup, and the Sleep Foundation says most can be adjusted by adding or removing hulls.

Watch out: Heavy and noisy when you move.

Adjustable pillow with gel-infused shredded foam

Best for: Memory foam fans who want a cooler first touch

Gel is a conductive material that draws heat away, and shredded fill adds airflow on top.

Watch out: The Sleep Foundation says the effect of gel is hard to judge before you try the pillow.

When to talk to a doctor: A cooler pillow eases comfort but does not fix a medical cause of sweating. The NHS says to see a GP if you have night sweats regularly that wake you or worry you, or if they come with weight loss you cannot explain, a very high temperature or feeling hot, cold or shivery, a cough or diarrhea.

Questions people ask

How do you adjust an adjustable pillow?
Unzip the cover and remove a small handful of fill at a time, testing in your usual sleep position, until your neck stays level with the mattress.
Are adjustable pillows cooler than solid foam?
Usually. The Sleep Foundation says shredded foam allows more airflow than solid foam.
Can I wash an adjustable cooling pillow?
Some shredded memory foam pillows can be machine washed, the Sleep Foundation says. Check the label and dry it completely.
Is an adjustable cooling pillow good for side sleepers?
Yes, if you leave enough fill in. The Sleep Foundation says most side sleepers need at least 4 inches of loft, and broad shoulders may need more, so side sleepers usually remove less fill than back or stomach sleepers.
What should I do with the extra fill?
Keep it in a bag. Fill compresses over time, and you can add some back later.
