I haven't cut myself with my knife lately.
Seriously, the thing I like most about our office space is that we've got a kitchen/break room that our secretaries keep stocked with pop and granola bars and things. My last job didn't have that, and I love it. I haven't really changed things to make things more comfortable. I've got a better mouse and keyboard than what ships with the new PCs, but that's because I like them better, not because of comfort.
I think I'm gonna take a picture of my desk just to show all the shit I've got piled up right now - I wouldn't have any room for "comfortable" things
