Would You Be Able to Sleep in This Standing Nap Box?

It's in the early stages of development.

A company in Japan came up with a new product called “nap boxes” to give workers a place to take a power snooze. But, you have to sleep standing up. They’re big cylinders with a door on the front that only fit one person at a time. Each one has three small shelves inside, strategically placed to support your knees, head, and bottom. So, you’re partially supported, but still vertical. It’s in the early stages of development, so they haven’t even demonstrated it yet.
