Hello, I would like to know if it is possible to manually move the seat forward and backward if the motor is not running. The armchair tilts and rises but I do not want the front to back and I have it on the right and left armchair anyway. Is it possible to manually move it because the wife sitting in the back with the child has there is not much space and he constantly complains that I put some in. My car is a Citroen C5 station wagon 2002. 2.0
