Drivers Seat Removal

[Tyke]

Need to replace my c3 drivers seat as the foam as given way and on longish drives i can feel the seat framework digging into my leg .

Ive ordered a second hand seat via the internet from a scrapyard and im trying to find instructions on how to remove the seat and fit the replacement in.

Any instructions with pictures would be great as ive never replaced a car seat before.

The seat ive bought is on its runners so im expecting ill only need to remove the electric seat belt sensor and the screws holding the seat in.

Any help or tips would be appreciated.
