While most WOULD hop off a chair, most WON'T because the thrill is, well, all but non-existent.
Most humans will never bungee jump because the of the risk, though many still will. And those that do, will likely only do it only once because after that what's the point. A fraction will go again, even fewer will go a third time, and a negligible (though dedicated) amount will take the leap at every opportunity.
Anyway, back to the chair. It's safe, but unexciting. A base, almost ironic, thrill COULD be attributed to the event. But, really, if you're the type who makes time and looks forward to jumping off chairs, then you are your own special, quirky you.
More power to you.
