LOL…yeah, I’m using a swivel chair. For VTOL VR, I like it for the arms that are perfectly positioned for resting my forearms in a constant and predictable location. I have to back my chair away from the desk and center my location so that I’m not reaching forward and hitting my desk.
My only problems are sometimes hitting the nav light switches in the F/A-26B because they are just “below” my left chair arm, so I can’t get my virtual hand there without the arm blocking the line-of-sight, so I have to swivel my chair left instead of looking left to access those controls. Fortunately, I don’t have to access those but once in flight (if at all).
I can see where depth of a chair (the distance from your crotch to the front lip of the chair) would be a problem for the items you have to reach down and forward for (like the arming / jettison / ejection controls)…as you described, you’d end up nut punching yourself or hitting the seat cushion.
Could you go less comfy and put a pillow or something behind you to force yourself forward in the seat by chance? Probably not the best solution…but nor is buying a single chair for once experience…haha…
