Remove seat cover

Hello Everyone,



I have a seam that has come apart in the seat of my 2000 megane.



I live in a hot country and there is no electric connection for the seat heater, although the wiring is connected to somewhere beneath the carpet.



I am asking for advice on how to remove the seat and then, removing the cover and after repairing the cover, replacing it.



Thanks for any help.



Colinito.
