Just imagine being so clueless that you don't understand someone having a mattress in his office. “What, do you even sleep next to a computer? EWW, NERD!” And these are the people who are the loudest about their intent to steer the whole industry “the right way”. To be honest, the motto that you don't need the skill to make decisions about the work requiring that skill, or that you don't need understand people doing it (the misleadingly formulated “anti-meritocracy” ideology) could only be taken without laughing out of politeness.

And, as far as I know, the lack of mattress in the room never stopped any stereotypical harassing boss, so what's the point here exactly?
