The assembly has a movable seat unit (3) sliding parallel to a base, and a backrest (4) and a headrest (5). A lateral slide (6) integrated with a fixed frame (2) cooperates with a caster (7) installed on cushion supports (41, 51) of the backrest and headrest. An angle between the supports is less than 180 degrees, and an articulation (9) between the backrest and headrest is moved from top to bottom and from front to rear.
