i have a y reg corsa but i have mislaid my service book?

you can get replacement service book from main dealers. if you got it serviced there you should ask for print out of all work done on your car reciepts/bills etc and put it in new service book. as for your back seat try pulling centre seatbelt out of seat then moving seat. might be stopping back coming forward. or if not might be catches stuck.
