These pods play on the fact that a bed at work is unthinkable but sleeping on a couch is not terribly comfortable - they fill a kind of social/technological void for "fatigue management solutions" in what, in reality, is a common practice: sleeping at work either for short periods or during long-haul overnight work shifts.
Whether or not these sleep hubs will make their way to the mainstream or remain luxury items for CEOs with too much money to spend remains to be seen. They are certainly conceptually intriguing but might turn out to be more hype than a real way to get a power-nap on the job.
