Hi Goldie, This is a site of member migrator, he gave me the link when I wanted instructions for fitting the rear boot seats. This will give you an idea of where all fittings are. Seye.
No hidden bolts as such. Follow the steps in the link above (but in reverse). The worst problem is likely to be the two 'bolts' at the base of the seat back. These are spring loaded and need to be pushed back into the seat back to getb them out of the mounting brackets (probably just one side and then the other is easy to get out). Use a screwdriver or similar to slide the 'bolts'.
