Two rows of about 15 sleeping lounge chairs are bathed in soft green light. Every chair has a normal outlet as well as a USB one. There's also another section that has about 8 high backed cozy sleeping pods. In this same section are 4 small private rooms/pods you can rent (30 euros for two hours I think) that has a clean bed and sink in it.
As seen in the first picture below, there's a selection of books (in German and English) that you can borrow while you are at the airport. The next time I am there I will take more and better photos to show all the great areas.
Bottom line: if you have a choice of airports at which to layover--chose Munich.
