An armchair (10) comprises a support frame (11, 12) to which a base seat (14), a back (16) and a footrest (26) are fastened, which elements are movable between a first and a second positions through power-driven movement means (21). The power-driven means (21) is suspended from said base seat (14) and movable therewith. Advantageously, the power-driven means is formed as a single power unit (21), having two independent driving shafts (22, 23). Still advantageously, the base seat (14) is pivotally mounted, at the front, to the support frame according to a first transverse axis (15); pivotally mounted to the rear of the base seat is the back (16) 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, so that upon rotation of the back about the second axis (17), the base seat rotates in the same way about the first axis (15). |
