I worked in an office with the Sit to Stand desks, and when I went to work from home full time (same job) I wanted to have a sit to stand desk also, like at work.   In my job we need to compare technical papers and arguments across multiple documents, so I need a not of space.  I am also at work a lot (65hrs/week), so need to make height adjustments whether minute, or from sitting to standing.  The range is big, there are 3 metal tiers.  The one at work is something like 70" x 30" and this one is roughly the same size.  It's the biggest size you can get.  It comes in 3 parts.  My husband put it together for me.  The motor works.  It is heavy and sturdy, and the desktop is great quality.  You need 2 people with both arms for the final step, and to move it around. It has 2 cord holes with brush liners so you can put the desk flush to the wall and the cords are more organized.  I use this every day.
