Just replaced the cable on my Natuzzi recliner. Turn the chair/sofa on its back. Undo the four square drive screws/bolts of the foot rest. Undo the two screws that hold the squab (the bit you sit on) to the metal frame, these are at the back of the frame as you look down, undo the two square drive screws/bolts t the front of the squab. Lift the cushion out, replace the cable (two screws) refit squab in reverse order. New cable from Natuzzi £10. Hope this helps.
