If you're looking for the ultimate in gaming furniture, you should take a look at www.thegamedeck.com and check out their Navis and Mayfly computer 'desks'. Why do I say 'desks'? These 'desks' leave ordinary office furniture lightyears behind...
The Mayfly serves as a normal (albeit really cool looking) desk. Then, slide - flip, it's a racing simulator. Done racing? Flip - flip and now it's a flight simulator. You can install your favorite racing system, flight system and keyboard and switch between these setups in seconds!
If that's not wild enough for you, you can splurge for the Navis workstation. The Navis has the same features as the Mayfly, but also has a built-in seat, brackets to support a surround sound system (including two speaker mounts behind the seat's headrest) and adjustable footrests.
These aren't cheap, but they are excellent for game center applications and simulation gamers looking to put together a really nice gameroom.
