The seating furniture comprises swivel arms (4). Two tension springs (10,11) which work in opposite directions are attached to the lower ends of the swivel arms. The springs are arranged on the sofa-bed body (1) in such a way that one spring is stressed in the swivel region, from one end position to the vertical position of the swivel arm, and the other spring is stressed from the vertical position to its other end position.
