Chairs are very useful. That's quite an obvious statement. I'd say that it's up there with the cup on the most important inventions list. Seriously. Whoever made the cup was genius.
Way back when all we did was chase moo-cow for a living, thinking about a holding device and making it is just astounding. That person who created holding technology must have been loved. I hope to think so. But then again, who knows if showing love was sending the poor guy out to gather things to put in his cup/bowl?
Back o the point; I love chairs.
