F-4 Ejection Seat

I stumbled across this awesome chair made out of an F-4 Ejection seat, the same site has a few other chairs made out of other ejection seats too. I wonder comfortable and ergonomic the chair actually is? It wasn’t designed for people sitting at a desk all day, but I have to admit having a chair like that would at least bring a smile to my face everytime I looked at it.
