Abstract
An armchair (10) comprises a support frame (11, 12) to which a base seat (14) and a back (16) are fastened, which elements are movable between a first and a second position through power-driven movement means (21). The base seat (14) is pivotally mounted, at the front, to the support frame according to a first transverse axis (15). The back (16) is pivotally mounted to the base seat, at the rear thereof, according to a second transverse axis (17) for rotation of the back itself. The back (16) has extensions (18) extending downwardly past said second axis (17) and having ends constrained to slide longitudinally of the armchair. In this manner, on rotation of the back about said second axis (17), the base seat rotates in the same way about said first axis (15).
