You have a chair that is capable of being connected to any technology.
When sitting in this chair you have a mind-machine link between you and anything it is hooked up to, being capable of controlling and understanding its senses with the same intuitive ease as moving your own body.
The chair also acts as a good place to meditate, allowing you to more easily push away the sensations of your own body to better become in tune with your own mind and/or powers.
