The Electric Xtreme duplex table by SIS Human Factors is great for those that must adjust their monitor height separately from keyboard height. The spring height adjustable keyboard mechanism adjusts with simple squeeze on the release paddle.
It takes a few seconds to adjust from one position to another. This is great because the mind can stay focused while the body is getting a rest from static posture.
Moving throughout the day promotes deep breathing and this increases creativity, clear thinking, and company profits. It also helps to prevent discomfort from working in one position too long.
