The invention relates to a furniture drive (12) for driving a movable furniture part (3), comprising: - a movably mounted driving element (16) for driving the movable furniture part (3), and - a coil spring (14) with a longitudinal axis (L) for applying a force to the driving element (16), said coil spring (14) having two end portions (19, 28) between which a winding portion (30) with spring turns (29a, 29b) is arranged. The length of the winding portion (30) of the coil spring (14) can be adjusted in order to apply a spring force by moving the driving element (16), and the winding portion (30) has a preferably periodically alternating sequence of spring turns (29a) with a larger diameter and spring turns (29b) with a smaller diameter along the longitudinal axis (L).
