We used to have ball chairs in the apartment in Tokyo (in fact we had only two real chairs, and one was a highchair for our then-little firstborn. Someone asked me about them today, and I had to think about why we stopped using them.
Then I remembered: our later not-quite-so-little firtsborn thought that they were such great fun it was becoming difficult to actually get any sitting time on the things.
