I can’t imagine this being comfortable, but a company in Japan is working on a concept for offices called “nap boxes” where you sleep (nap) standing up.
These boxes are shaped like water heaters with a door on the front . . . and are claimed to be comfortable.
STANDING UP? Comfortable? Come on.
The concept is in early stages of development, so they haven’t even demonstrated it yet. They just have a rendering.
Would you be down to take a nap at work . . . standing up?
