How to Choose the Best Pillow
Last updated August 2026
Quick answer
Choose pillow loft (height) by sleep position: side sleepers need high loft (4 to 6 inches) and firm support, back sleepers need medium loft (3 to 5 inches), stomach sleepers need low loft (2 to 3 inches) or no pillow. Memory foam and latex give the most consistent neck support; an adjustable pillow you can add or remove fill from is the safest bet if you are unsure or sleep in multiple positions.
Why loft is everything
A pillow has one job: keep your head and neck in line with your spine. Get the loft wrong and you force the neck into a bend all night, which is a leading cause of morning neck and shoulder pain. The correct loft fills the exact gap between your mattress and your head in your usual sleep position, no more and no less. Because that gap depends on your position, shoulder width, and how far you sink into your mattress, loft is more important than fill material. If you recently changed mattresses, revisit your pillow too; our mattress buying guide explains how sink depth changes the gap.
Loft and firmness by sleep position
| Position | Ideal loft | Firmness | Best fills |
|---|---|---|---|
| Side | High, 4 to 6 in | Firm | Memory foam, latex, adjustable |
| Back | Medium, 3 to 5 in | Medium | Memory foam, latex, down alternative |
| Stomach | Low, 2 to 3 in | Soft | Thin down alternative, thin foam |
| Combination | Medium, adjustable | Medium | Adjustable shredded foam |
Side sleepers have the widest shoulder-to-head gap, so they need the highest, firmest loft to keep the head from dropping out of alignment. Back sleepers need medium loft that cradles the neck curve without pushing the head forward. Stomach sleepers should use the thinnest pillow possible, or none, to avoid cranking the neck upward. Combination sleepers benefit most from an adjustable pillow whose fill can be tuned on the fly. Browse the full range on our pillows hub.
Fill materials compared
Memory foam. Conforms to the head and neck for personalized, consistent support and the best pressure relief, which makes it the top choice for neck-pain sufferers. Solid foam can trap heat; shredded or gel-infused versions sleep cooler and, in shredded form, let you adjust the fill. The Coop Home Goods Original is a popular adjustable shredded-foam pillow, and the contoured Tempur-Cloud is a go-to for dedicated neck support.
Down and down alternative. Real down is luxuriously soft and moldable but pricey and less supportive; down alternative (polyester) mimics the plush feel for less, and is hypoallergenic. Both need frequent fluffing and have shorter useful lives. The Beckham Hotel pillow is a well-known down-alternative option.
Latex. Responsive and naturally cool, latex supports without the slow sink of memory foam, so you rest on top rather than in it. It is more durable than foam and resists dust mites. The Purple Harmony pillow pairs a latex core with a cooling grid.
Buckwheat and specialty. Buckwheat hulls give firm, breathable, fully adjustable support with excellent airflow; water pillows let you dial firmness by volume. These niche fills suit specific needs but have a learning curve.
Price tiers
Budget (15 to 40 dollars). Down-alternative and basic foam pillows. Perfectly serviceable, though they compress faster and need replacing sooner. An Amazon search for pillows by sleep position shows the field.
Mid-range (40 to 90 dollars). Adjustable shredded memory foam, quality latex, and better covers with washable, breathable fabrics. This is where most buyers get the best value and the ability to fine-tune loft.
Premium (90 dollars and up). Advanced cooling systems, contoured cervical designs, and durable natural latex that holds its shape for years. Worth it for chronic neck pain or hot sleepers who have tried everything else.
Why adjustable pillows are the safe choice
If you are unsure of your ideal loft, cannot find a pillow that fits, or switch positions during the night, buy an adjustable shredded-foam pillow. You can add fill for more height and firmness or remove it for a lower, softer feel, effectively tuning one pillow to your exact neck. It removes the guesswork that makes fixed-loft pillows a gamble and is the most forgiving option for combination sleepers.
A practical way to dial it in: fill the pillow completely, lie down in your main sleep position, and have someone check whether your nose lines up level with your chin and your ears sit over your shoulders. If your head tilts up toward the ceiling, remove a handful of fill; if your chin drops toward your chest, add some back. Store the extra fill in a bag so you can retune later as the foam settles or if you change mattresses. Most people reach their ideal loft within two or three small adjustments over the first week, and the pillow keeps that setting until you decide to change it.
Pillow size, covers, and specialty shapes
Standard pillows (20 by 26 inches) suit most sleepers and fit a standard pillowcase. Queen (20 by 30) and King (20 by 36) pillows give more room to move and help restless sleepers who shift around, and they fill the width of larger beds better. A body pillow is worth considering if you are a side sleeper or pregnant, because hugging one and placing it between the knees keeps the top hip from rotating and pulling the spine out of line.
The cover matters more than people expect. A breathable, removable, machine-washable cover, usually cotton, bamboo, or a poly blend, keeps the pillow cooler and far easier to keep clean than a sealed one. Look for a quality zipper and a cover you can take off without a struggle.
Beyond the basics, a few specialty shapes solve specific problems. Cervical or contour pillows have a raised edge that cradles the neck and a lower center for the head, which many chronic neck-pain sufferers find keeps them neutral all night. Wedge pillows elevate the upper body for reflux or congestion, similar in effect to an adjustable base but far cheaper. Cooling pillows built around latex, shredded foam, or gel grids are the answer for people who flip to the cold side of the pillow every hour.
Care and replacement
Wash your pillow every 3 to 6 months following the care label, and use a pillow protector to extend its life and block dust mites. Replace pillows every 1 to 2 years, sooner if you see lumps, notice a persistent odor, wake with neck pain, or find the pillow no longer springs back when folded in half. Fluff memory-foam and down pillows daily to maintain loft, and redistribute the fill in shredded-foam pillows periodically so it does not clump.
Common mistakes to avoid
- Buying the same loft for everyone in the house. Loft is personal; a side sleeper and a stomach sleeper need very different pillows.
- Stacking two pillows. Two thin pillows shift and slide, ruining alignment. Use one correctly lofted pillow instead.
- Keeping a pillow too long. After a couple of years pillows lose support and collect allergens, undermining even a great mattress.
- Ignoring heat. If you sleep hot, avoid solid memory foam; choose shredded foam, latex, or a gel-infused design.
- Overlooking the mattress relationship. A softer mattress lets your shoulder sink more, reducing the loft you need. Reassess your pillow whenever you change mattresses.
Frequently asked questions
How often should I replace my pillow? Every 1 to 2 years. Over time pillows accumulate dust mites, lose loft, and develop permanent compression that pulls the neck out of alignment.
What is the best pillow for neck pain? An adjustable shredded-foam pillow or a contoured cervical foam pillow, because both let you keep the neck neutral. The Tempur-Cloud and Coop Home Goods Original are common recommendations.
Should side sleepers use two pillows? For the head, one properly lofted pillow beats stacking two. A thin pillow between the knees, however, can help keep the hips and spine aligned.
Can the wrong pillow cause neck pain? Yes. A pillow that is too high or too low forces the neck into a sustained bend all night, which is one of the most common and most fixable causes of morning neck stiffness.
Are cooling pillows worth it? For hot sleepers, yes. Latex, shredded foam, and gel-infused designs breathe far better than solid memory foam and can meaningfully reduce overnight overheating.
Bottom line
Pick loft by your sleep position first: high and firm for side, medium for back, thin for stomach. When in doubt, buy an adjustable shredded-foam pillow so you can tune the height to your own neck, and replace it every year or two before it quietly sabotages your sleep.
