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. Easels are traditionally used by painters to support a painting while they work on it, normally standing up, and 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 are available. Easels are typically made from wood, aluminium or steel.
