Now you can take a nap anywhere -- in your home, at the mall, in the airport, or even in a store -- thanks to MetroNaps and their pod systems. And as their Website says, a mid-day nap boosts alertness, learning, memory and mood.

These pods are sphere-shaped, and surround your upper body in order to block out sound as you recline on the "ergonomic" leg rests. It even has a built-in alarm clock; no annoying noises, just a gentle vibration to wake you from your slumber. What's interesting about MetroNaps is the focus on the supposed "science" of naps, and they even say that naps can make you look younger. They suggest employers order a few pods for the office in order for workers to stay productive. I can foresee many people abusing the napping privilege by extending the recommended 20 minute power nap.

It's kind of a frightening contraption at first glance, looking much like a giant football helmet, but I think I might be able to fall asleep in one if it came down to it. And I certainly wouldn't mind being able to take naps during the workday; if you're in New York, there are two MetroNaps locations where you can give the pods a try.
