Get an old-school drafting stool with a back support. That's what I do for my standing desk. It encourages me to move around a lot because it's so easy to just stand up, or lean on throughout the workday. I stand, sit, get up and pace when I'm thinking. Much better than a "sitting" chair since I feel like that just encouraged me to slouch down and not really move around or change position through the work day and much better than just standing through the entire day -- which feels like a return to working as a cashier.
