An easel is an upright support used for displaying and/or fixing something resting upon it, at an angle of about 20° to the vertical. In particular, painters traditionally use an easel to support a painting while they work on it, normally standing up; easels are also sometimes used to display finished paintings. Artists' easels are still typically made of wood, in functional designs that have changed little for centuries, or even millennia, though new materials and designs exist. Easels are typically made from wood, aluminum or steel.
