You are not alone if you are confused by what exactly a VR chair is, but The Tech Report can help.  Aaron Schradin created the Turris VR chair which essentially allows you to steer VR games with your butt.  By leaning forwards, backwards or to the sides you can make your in game avatar move, instead of needing something in your hands.  Swiveling is also mapped, which is more important than you might think; with your torso decoupled from your head movements you can look around while maintaining the same walking direction.  The Turris also doubles as a case, you can install your PC directly into the chair to clean up the overall look of your VR rig.  Check out the video and full review for a look at this interesting piece of technology.  There is no price nor release date yet but Aaron is aiming for Q4 for the first release.

"Praevidi's Turris VR Chair lets players navigate seated VR experiences by shifting their bodies, an approach that decouples head- and torso-position tracking to create a potentially more immersive experience in VR environments. Join us as we explore this device and its implications for the future of VR control."
