Long story short on Thursday my passenger seat was wrecked.
A cat has urinated on it.

The seat was removed from the car and valeted as soon as possible which failed because the scent is still very much present.
I have been to various car salvage places and had no luck in finding a passenger seat.
My last resort was Ford. The parts dept was closed today but I was told by a man in the dealership that it is possible to replace the bottom part.
Before spending money on this car, I want to know is it possible to remove the cover and sponge from the base of the seat and I can really clean it properly (hopefully) and is it difficult getting them back together?
Any help/advice would be much appreciated.
Thank you
