Hi Nick,

An interesting idea this "beanbag" seat.

I am going to try it in my fishing yak. When fishing I need to be able to turn and shift my position quite a bit - this might be just the ticket.

A dowel-and-velcro arrangement might be useable to control the volume [thickness/support] of the cusion.
