the side bolsters are then unclipped from the font by levering up the metal tabs and unhooking the fabric,

you then need to turn the fabric inside out from the bottom of the seat upwards till you are just over half way up, you then need to pull the foam bolsters away from the seat, they have a small amount of glue holding them in place and may make some nasty ripping noises, nothing to worry about if your doing it properly, you then need to undo some more fabric clips holding the back fabric to the seat frame, lever them off with a screwdriver
