There Is A Difference Between A Deep Sleep,

and a power nap, 

because of the pressure of work some Japanese workers turn to short power naps, they have been proven to give workers more concentration and work efficiency, as long as the person doesn’t go into deep sleep. In order to make it easier for people to get power naps pretty much anywhere, one company has begun installing vertical sleeping pods called ‘Gireaffenap’ in cafes all over the country,

each Gireaffenap pod features an alarm system that can be set by the user, as well as support points for the various parts of the body – head, buttocks, calves, and feet, to ensure that the user maintains their upright position when napping. The pods also feature a height adjustment system so that anyone can achieve the perfect posture while using them, Giraffenap is a standing sleeping booth created by Hokkaido-based Koyoju Plywood Corporation. The company doesn’t say why they chose the name, but it might be because not only are giraffes capable of sleeping while standing up, but because they only sleep for a few minutes at a time, what we’d call a “nap.” for the full story have a look here, for myself I can think of nothing more uncomfortable than waking up with bent knees with the weight of my body on them, but there it is.
