Terms of use

PillowFacts is operated by Delaware Goods Company LLC ("we"). Using the site means you accept these terms.

What this site is

An independent index of pillow specifications, and a calculator that estimates the pillow height a person needs. It is free to use and sells no products.

Not medical advice

Nothing here is medical advice. The site describes the geometry of pillows and does not treat, diagnose or prevent any condition. If a question needs a clinician, ask one.

Specifications and estimates

Specifications are read from each maker's own page on the date shown beside them and can change without notice. Check the maker's current page before you buy.

The calculator's result is an estimate from the figures you enter. It is not a guarantee of fit.

Independence

We are not affiliated with, endorsed by, or connected to any manufacturer named on this site. Trademarks belong to their owners.

Links to other sites

We link to makers and other sites. We do not control them and are not responsible for their content, policies or availability.

Quoting this site

Quoting and linking are welcome. If you quote a figure, keep the maker's page URL and the date it was read with it.

Advertising and commissions

How the site can earn money is set out on the disclosure page.

Changes

We may update these terms as the site changes. The date at the top shows the latest version.
