1. Disconnect battery
2. Take off plastic covers over the bolts
3. Remove bolts
4. (Tricky bit) unclip wiring for airbags, electric seats and seatbelts all are under the seats, you will have to cut some plastic clips too
5. Remove seats
I may have some pics somewhere I will have a look tomorrow
Obvious point, make sure seats are in the right position to get to all the bolts before you disconnect the battery
