I tend to sit a little sideways with my right butt cheek on the seat and my left side facing out. I am right handed, so this keeps the bow a little farther from the stand's foot platform. On closed shots, it is some times necessary to cant the bow considerably to clear.
The best elevated stand I ever had was one I made with pressure treated lumber. It was massive and had a four foot square platform with a seat on it. We called it the tower. I don't know how long it would have lasted, because bad weather blew down the tree it was attached to. On private land, I like permanent stands.
