I'm 6'5"........ tried quite a few ideas, everything from buckets on up......the best so far for me is the 'hobbie mechanic stool', it adjusts up and down pnuematically and swivels which help with fatigue, there is a tray directly above the casters, that is real handy when changing out decoys in the dark. cost $25 on sale, $35 if not, it looks like the stool the doctors use in their office.
A new idea for this year is the 3 dollar yard sale "super adjustable office chair" I picked up this summer , I adjusted it so it leans way,way forward, because we always do that trying to see under the ice, and it has soft arm rests, never had arm rests, very soft chair, I can see myself falling asleep in it............and missing the big one.....
