Abstract
A chair has a reclinable backrest formed by a series of at least three superimposed segments articulated together about respective substantially horizontal axes to define, in the reclined position of the backrest, an arcuate configuration with a curve substantially corresponding to that of the arched back of a user. Resilient means are provided for resisting the movement of the segments towards the position corresponding to the reclined position of the backrest.
