dannyboy1101 saidI'm confused as to why one would need such a thing. Cheap hotel.
Or when you're stuck in the airport for just too short a time for a hotel, but too long for your back to tolerate the benches (with their obligatory arm rests) at the gate.
You can rent them for as little as 15 minutes.
They are sound proof, and you can store your luggage and go to sleep without fearing that somebody is going to steal it from you. (One of my friends once had their laptop and bag stolen from underneath his head while he was napping at the airport). They have TVs, wifi and power and air conditioning.
I think Moscow, Dubai and some Japanese airports have them. Now if only Chicago will set them up people won't complain so much about the delays.
