I can't see any realistic way that the ergonomics would be better than your haphazard hotel room setup. Reality is that the device still has weight on your head and neck and is still kind of tiring to wear for long periods of time.

It's still 1.5lbs hanging off the front of your face and over hours that's still straining.

Lying down or in a recliner or something where you're not really having to support the device yourself is about the only way that I feel you might achieve any kind of better result in an ergonomics sense for a significant length of use time.

(Disclaimer: I had one to demo for a few months and used it/experimented with it sporadically, I don't own one.)
