That zombie-looking person standing next to you, may actually be asleep
The vertical sleeper is in a constant state of readiness, never succumbing to collapse. Homelessness is most often marked by the forbidden act of lying down on the sidewalk, an act that the vertical bed circumvents.
The artist who created this concept will tell you that it’s some artsy-fartsy way to make a statement and get yourself some polyphasic sleep, which is the practice of sleeping multiple times in a 24-hour period, but really it’s just an excuse to be lazy whenever and wherever you want. So lazy that you don’t even lay down.
