I was postulating because I've never been on one. How much force does it take to make them flex, and in what direction(s) do they flex? I can imagine them slightly going side-side, contributing somewhat to rocking, and altering the contact dynamics between seat and bottom. Of course this is all speculative, but I'm having some trouble letting go of the notion.
