: I'm customizing my Mariner Max cockpit with sliding seat. There is extensive
: design work involved to keep the seat a slider. I need to roll with ease,
: so which type of seat is better, a flexible band type, or a solid type
: made from minicell foam? I would appreciate any opions.

I agree with Lee. Back rests are a highly personal thing. Since you want to roll, I would suggest that you let the back rest move. This might be easiest with a band. I am very happy with my articulated backrest, but it may be hard to adapt to a sliding seat.
