The main reason I prefer an electronic height-adjustable desk is the height presets.  Imagine if every time you sat down in your computer chair you had to adjust it from the lowest setting to a comfortable height.  How much time would be wasted?  It&#x27;s not the effort of cranking it there, it&#x27;s determining where the optimal height is.  With electronic, you set it once, and then whether you&#x27;re sitting or standing, your surface is at the ideal height.  (Elbows approximately 90 degrees while typing, etc.)
