From Thinkgeek:

Command the Enterprise from your very own Command Chair, styled after Captain Kirk’s bridge chair from Star Trek:TOS. Fire your phasers and photon torpedoes. Order the warp drive engaged. Negotiate with alien races. Dramatically “fall,” this way and that, when your ship is struck with a shot from a Klingon Bird-of-Prey. Simply provide your own fill and you’re ready to take command.

For those interested in getting one of these, you need to purchase the filler separately. Amazon has some really cheap ones!
