I have been researching office features which allow flexible space which the worker has control over. I found these desks which are height adjustable so that workers of different heights can sit comfortably and can also stand to work if they want to.
I think this is such an excellent idea, as sitting at a desk all day can cause back pain and bad circulation - being able to stand to work for even just an hour twice a day would really help.
The height range (shown in green) is 720 - 1200mm
