forward. Backward canting makes kneeling support a problem and is a back killer over distance. The other issue is sciatica. Your legs can become numb with pressure of the front support on the back of the thighs.
I have had a couple of seats installed level. Not long before we took a saw to the back drops to cant the seat forward. 3/4 inch difference between front and back as far as distance seat to floor is standard.
Look at many shapes of canoe seats. Many are shaped in the front to avoid nerve impingement.
