What is a Windsor Chair?
A Windsor chair is a wood chair whose back and sides consist of multiple thin,
turned spindles that are attached to a solid, sculpted seat; its straight
legs splay outward and its back reclines slightly. It is widely agreed that
the Windsor chair was developed in the late 17th or early 18th century
in the vicinity of Windsor, England.

But as to who invented them in the first place, there are only theories.
One suggests that a spinning-wheel maker was responsible. The splayed legs of
his elegant machine are reminiscent of Windsor chairs in both decoration and geometry, while
the wheel supports translate into arm-posts, the spokes into spindles. Add some bent wood to
contain the back and you’ve got something we might recognize as a Windsor chair.
