I did get to try one, not for hours mind you, but I found the chair comfortable. I was worried the arms would dig into the sides of my legs but they were fine. I think their saving grace is they are not very high and are rounded... I wasn't caught by them and they didn't constrain my leg movements.
Maybe someone could say how high the arms come up? That could be helpful too for some.
My beam when sitting is 22" - hate to say it
but I can appreciate it could help.
I forget how easy the chair was/wasn't to adjust but I would probably limit the amount of adjusting I did to it while I was in it just to reduce wear & tear.
I haven't called my dealership yet to see if they can tell me but I'll re-iterate my wish that Hobie would post the chair's weight load. Boat capacity and seat capacity are two different things! I'll post it if/when I find out. It's still not kayaking or kayak ordering season here yet!
