A pillow is a small purchase with a big effect on how you feel in the morning. Buying one online means you can't squeeze it first, so it pays to know which details on the listing really matter.
Start with your sleep position
- Side sleepers need the most height (loft) to fill the gap between ear and shoulder. Look for medium-high loft and medium-firm foam.
- Back sleepers do best with medium loft and a gentle contour that supports the curve of the neck.
- Stomach sleepers need a low, soft pillow, or sometimes none at all, to keep the neck from bending upward.
Solid foam or shredded?
Solid foam keeps its shape and offers consistent support. Shredded foam lets you add or remove fill to adjust height and tends to sleep cooler. If you're unsure about loft, adjustable shredded fill is the safer bet.
Check density and certifications
Higher-density foam lasts longer and resists flattening. Look for third-party certifications that test foam for emissions and harmful substances, and expect a mild "new foam" smell that fades after a day or two of airing out.
Read the cover and care details
A removable, machine-washable cover is a must. Bamboo-derived and cotton covers breathe better than polyester. The foam itself should usually be spot-cleaned only.
Know the return window
Your body can take one to three weeks to adjust to a new pillow. Before you buy, check the seller's return policy for bedding and whether opened items qualify.
