I've no idea why you were downvoted. The idea of a $20 solution for trying-out a standing desk (two crates upturned and a plank of wood on top) vs. a commitment of $300-$400 seems like a worthwhile contribution. And as far as a criticism of it being "wobbly" -- i've seen automobiles perched on top of plastic milk-bottle crates. Not that I'd recommend it, but surely one will safely hold a relatively breezy laptop and a monitor (15kg total?) Amazon even sells a multi-level cardboard standing desk for $25 that's perhaps a touch more attractive than a milk crate: https://www.amazon.com/Spark-Ergodriven-Perfect-Standing-Medium/dp/B01GGNV6VQ https://www.amazon.com/Spark-Ergodriven-Perfect-Standing-Med... So give it a try. See if a more neutral head-up posture and straight spine are agreeable. If so, consider an upgrade to a "real" standing desk. If not, no real risk or loss.
