yeah I totally get that, I was in the same camp for the longest time. Thought it was just an expensive fad. What changed for me was setting a timer to actually switch between sitting and standing every hour, instead of trying to stand all day. That movement back and forth made a bigger difference for my lower back than just standing still. My old desk made me slump, but now I catch myself and switch positions. It's not the desk itself, it's forcing myself to break up the posture.
