I think a recliner set up could work. In that position you can wear it all day.
The top manufacturer is BoboVR, but they obviously haven't yet made one for the Vision Pro.
I don't get why Meta and Apple don't include this as the default, given that it's obviously the optimal solution. Then again, at least Apple even used a heavy and unnecessary metal frame in the headset, so ergonomics clearly isn't their top priority.
A monitor isn’t much of an issue, just use a VESA mount. Keyboarding is more difficult in a reclined position, unless you can use it fully blind.
