About

Written and maintained by its editorial desk, this reference covers wool as a pillow fill and stops there.

What is out of scope?

Wool duvets, mattress toppers, and wool as a clothing fibre, all of which behave differently enough to mislead.

Where a pillow pairs wool with buckwheat hulls, the hull side is covered only as far as it changes the pillow.

How is it funded?

Publishing costs are met privately.

Makers are named only where a point about the fill could not be made without them.
