It depends. I suggest you first try to work at your desk with a tray on top or something that lets you try out switching between standing and sitting all the time. See if you’ll actually be switching between standing and sitting and enjoy it.

I have one. Bought it about 9 years ago. Thought it was so cool. After the first week I barely ever moved it to standing.

Fast forward to now. I have some pretty bad lower back pains that I do like standing frequently. Unfortunately the desk I have is motorized not manual; and it stopped working. So I now have a tray that I switch in and out during the day to sit and stand.
