I own 3 Steelcase Leap chairs (previously owned an Aeron and didn't care for it). The one I'm sitting in now, I've owned since 1999. It's survived 4 cross country moves and numerous transports to job sites and back.

I originally bought one for work (as I didn't like the "ergonomic" chairs that the company I was at provided) and liked it so much that I eventually got another for my home office and my wife got one as well.
