I've got a kind of stealth gaming rig setup in the house where the monitor is on the wall and there is no desk. When I want to use it I want to wheel out a gaming chair that provides a keyboard and mouse tray. I can then hide it when done. Is there a decent version of this in existence? Does anyone make one that comes as a whole or are there any that fit seamlessly together? I've been unable to find a decent all in one.
