Removing the fabric
Turn the seat over, you need to remove this clip that holds the back of the seat to the bottom.
Go easy, don't lose your pateince, and try not to put a mark in it.
The best way is to get a round screwdriver in the very bottom (further down than in this picture) and gently pry downwards
There you go!
Next I remove the base.
Starting with the smaller section shown release the clips from the outside of the base
Ok, no turning back now...!
