hiya buddy , the centre panel with the diamonds on is 12 1/2 " wide by 17 1/2" long , the seat back i estimate to be around 17" wide by 24" long.
update on the porsche 944 seats im doing. boy what a pita these are to recover , the original covering was a brown plastic that was imprinted to look like vinyl , horrible nasty stuff

. to allow a new cover to be fitted ive had to use a little artistic licence , ive created a three peice back with hidden zips , this allows the front cover to be hogringed on .
ive followed the stitch lines in the front of the seat onto the back of the seat.
the passenger seats almost finished , just to smooth the cover out and `set` the piping in place .
.
take it easy guys , ade :ILU:T:
