Abstract
A legrest for a dental chair has a telescopically nested section. A cable and pulley system automatically extends the nested section from the legrest as the legrest is moved from a generally vertical position to a generally horizontal position. Bias springs return the section to its nested position as the legrest moves back towards its near vertical position.
