There are sit/stand desks where I work, however I would rather get up and walk around and take a break than desk-up and keep working :o) That said we have Steelcase Leap chairs at work. http://www.steelcase.com/en/products/category/seating/task/l... and at home I have a Herman Miller Mirra http://hermanmiller.com/Products/Mirra-Chairs I hope to purchase a Herman Miller Embody Chair next year.
