Sleepbox
 

I found this and thought it was rather interesting. I say bring back nap time, now there's no excuse heh

Sleep Pods

Yea, airport sex! :D

Despite the variations of what constitutes a 'box' or a 'pod' (think Japanese industrial business hotel), this is a neat contraption.

I like the 'Hostel Edition' as well.

Hell, I want one of those for my apartment. That's nifty.

Just how soundproof? That's the real question. Airports can be loud, obnoxious places. Oh, and I've slept the night at the airport. It wasn't fun.
