I had an abusive ex who had one of those. The times I tried to sit on it, lost my balance, and landed painfully on the floor were, in retrospect, a pretty accurate microcosm for the rest of the relationship.
These things are great my coworker had one and it looked interesting so I got one for myself. It was great for gaming as it puts you into a more power pose like if you were riding an Enduro motorcycle and since you get tired sooner you are more inclined to get up and be productive maybe
