What's so great about chairs?

I only collect event/PQ chairs. I refuse to pay mesos for a chair, especially ones that cost over 100m (Beach chair is an exception, paid 60m for it because it reminds me of home :B), I personally think it's a waste of money. Most of them do look awesome, though, and it's probably why most people collect them. Or simply for the sake of collecting, which is pretty fun to some people. I think some of them are ridiculous-looking, though.

I have the Lotus Leaf chair and it's actually semi-useful, heals 200 HP and MP!
