Have you been told a standing work station is better than sitting? Have you wanted to try it? I personally don’t believe that standing all day is any better than sitting all day. My opinion is that having a work station that allows you to sit OR stand for different portions of the day would be ideal.
It is important to remember that you can have bad posture standing as well as sitting. When standing, strive to keep your weight distributed equally on both feet and keep your ear, shoulder, hip, knee and ankle in alignment. (If you were to connect the dots of your ear, shoulder, hip, knee and ankle from a side view, it would make a straight vertical line.)
So, if you are curious and not certain that standing would work for you, but don’t want to invest a lot of money in committing to finding out, here is a reasonable option that you might want to explore to give a standing work station a trial.
