hmmm

This will last 100 years. The flatpack bunk beds you buy for $259.99 may last til thanksgiving.

It's not pretty but it's functional. Should get some bed sheets though

Pitch it as a modular living quarter system repairable under resource-constrained field conditions and any army will buy it (it also simplifies logistics)

I mean, the clamps are ugly, and I would fear to rip my skin up. But besides that, I dig it.

I'm sorry but you need to put pins through those poles or at least a wooden board beneath the load. I don't care what the friction is, this won't hold forever.

I wish I had higher ceilings in my room I would absolutely do this

why not add some ladder steps? some long bolster pillows?

Judging by the bookshelves, I think you'd bonk your head trying to get into or out of those chairs. The bed would be safe for sleeping but you'd want to be careful about lively activities that might slide the board off to the right of the photo. Given the rest, and the fact it would be a pain to arrange sheets and pillows, that's probably not going to be an issue, though.

Looks expensive.

looks like my mates house. Only downside I see is that you need ventilation on the mattress or it will mold.

When I was in my early twenties I slept on a scaffold bed much like that more than job. It was usually in a cargo container with nine other people. It was effectively free lodging and I was working seven days a week. Twelve hours a day with overtime.

Good times and great pay.
