Though I can understand where you're coming from; I recall really "playing" Dactyl Nightmare in the mall (most people would just stand around and stare in the game - it was kinda stupid), and I would walk away fairly sweaty from the "workout" of playing the game (crouching, moving, shooting, aiming, etc).
I always thought that was one of the best aspects of VR gaming - that I could actually be in the game, and not just viewing it through a window semi-passively.
It would be nice to be able to just sit down and relax in VR while playing a game.
Have you ever heard of the company Flogiston - and the Flogiston Flostation?

You can find some more pictures and stuff with google - the company no longer exists, and I don't know if any of the prototypes or such are still around; if they are, they are probably "unobtainium".
But anyhow, part of the system was a particular style of "zero gravity" posture chair, as you can see from the pictures and such. So playing Elite Dangerous in an HMD from a similar chair might be an interesting experience...
