From wiki:
The Su-34's most distinctive feature is the unusually large flight deck, which not only provides side-by-side seating, but includes space for a galley, a latrine, and a bunkbed. It was joked that "It's got a bigger cockpit than the Tu-160". Much of the design work went into crew comfort, which resulted in novel features such as pressurization provided by the air conditioning system, rather than with oxygen masks and a massage function in the K-36 ejector seats.
Niiiiiiiiice. :-)
