OP here. Of important note, I also have Ehlers-Danlos Syndrome, a connective tissue disorder that makes me especially prone to muscle stress and joint instability.

Good ergonomics apply in VR just as they do in any occupational setup. I was suffering from cervical lordosis before ever going into VR - but because I've used it to increase my range of motion throughout the day, and eliminate my need to ever hunch or squint, I'm feeling much better than before going full-time VR.

But: don't do it all at once. Work up to it, balance the weight appropriately, position screens properly, and take breaks! Yes, I do 8-10 hours a day in VR - but not all at once.

Very good points

I imagine similar to the posture of riding a motorcycle, seeing as a helmet on average would weigh a similar amount to a VR headset.

As a rider myself, the first week or so was a bit rough and an unusual feeling- it wears off after that.

That's a good point, having raced motocross myself I'd agree.

IME, it's mostly a step up from a monitor, because I can position the displays wherever I want. In addition to OP's sitting and standing setups, I spend a lot of time working lying down, or sitting extremely back, with my head fully supported.

And I suppose with these displays there's no reason why you couldnt stand either.

Hang out the washing and read your emails.
