Earlier quoted context omitted.
I use the Fredrik and it works well for me as a standing desk.
I looked into that, The 98cm max-height doesn't work for me. I'm 6'3".
The Fredrik I'm standing at right now can go all the way to 150cm, just make sure you get the correct version. There's a short one and a taller one.

If you look at this pic you'll see the tabletop plus two shelves. The shelves and tabletop can all be mounted at different heights. I mounted the shelves below the tabletop and my tabletop is at 104cm but can go much higher.
